Asia's Largest Single-span Flower Greenhouse to be Set up in Anning

Covering an area of ​​158 acres -  equivalent to the size of 14 standard football fields, with expected annual output of fresh cut flowers over 30 million... it will be the largest single-span flower greenhouse in Asia. It is expected to be put into operation in the Rose Modern Industry Plantation Base of Anning Modern Flower Industrial Park within this year. The greenhouse automatically controls the temperature, light, water, humidity, and air in the greenhouse through automatic sensing probes, and realizes fully automatic management. After completion, it will "make a sample" for a peaceful, efficient, intelligent and ecological flower planting mode.

Asia's Largest single-span flower greenhouse

In August 2020, the Anning Modern Flower Industrial Park project was officially launched. Among them, the Rose Modern Industrial Plantation Base was built in 2009, covering an area of ​​more than 1,000 mu, with a planting area of ​​more than 600 mu. After the base is built, the traditional soil cultivation mode will be maintained. In recent years, with the rise of soilless cultivation, in August 2020, Anning Northward Flower Industry Co., Ltd. upgraded and transformed the traditional planting model in the park, and in 2020, 416 acres of fertilizer-saving, controllable, environmentally friendly, and high-yield plants will be built. High-quality soilless cultivation intelligent modern flower planting base.

After upgrading and renovation, the production of roses in the park has doubled. According to reports, soil cultivation produces about 60,000-80,000 flowers per mu per year, and the yield of soilless cultivation is 2-3 times that of soil cultivation, while the amount of labor and fertilizer used in soilless cultivation is only two-thirds or even of soil cultivation. half.

Walking into the Rose Modern Industrial Plantation Base in Anning City, I saw roses neatly lined up in the greenhouse. The flowers were raised in a half-meter-high foam planting tank with a drip irrigation belt in the middle. There were many intelligent sensor probes installed in the shed. . "This smart probe is very powerful. It can sense which flower is short of water, fertilizer, or how much. The other end of the sensor probe is connected to the water and fertilizer workshop. The staff adjusts the parameters according to the actual situation of the flower plant, and automatically distributes fertilizer and water. , and then water and fertilize through the drip opening on the drip irrigation belt." Wang Zixi, deputy general manager of Anning Northward Flower Industry Co., Ltd., introduced.

"Not only that, the shading net in the greenhouse will automatically switch on and off according to the light intensity, and the circulation fan will automatically switch on and off according to the temperature and humidity. In the past, one person could manage up to 3 acres of land. Only part of the meticulous bud picking and flower cutting work requires manual operation." Wang Zixi said.

It is worth mentioning that during the entire rose planting process, not a single drop of waste water will flow into the soil. In addition, the company has also built the world's most intelligent and advanced fresh-cut flower processing workshop, with an average daily maximum processing capacity of 600,000 stems.

More importantly, carbon dioxide, the "culprit" responsible for global warming, will play a role in the newly built Asia's largest single-span greenhouse. The company will entrust a third-party company to collect industrial waste gas, purify the carbon dioxide and supply it to the greenhouse to increase the efficiency of rose photosynthesis. In this way, not only the utilization rate of waste gas can be improved, but also the carbon dioxide content in the atmosphere can be reduced, and high-quality flowers can be planted.

Greenhouse Brings "Smell of summer" in the cold winter

During the Spring Festival holiday, many people are still busy in working, like the seedling farmers in Dongtai City, Jiangsu Province, the "Town of Watermelons". With the help of modern agricultural technology, even in the cold winter, the watermelon seedlings here are raised. And this has brought them good economic benefits.

Although it is a cold day, the smart greenhouse in the seedling base in Dongtai City, Jiangsu Province is warm and green. Watermelon farmers are skillfully grafting watermelon seedlings.

Liu Guorong, head of a seedling base in Dongtai City, Jiangsu Province: In the past, the culture of watermelon seedlings could not be guaranteed due to the impact of cooling and cold waves. After electrified intelligent constant temperature cultivation, precise control of temperature, humidity, environment, etc. has been achieved. Now it is possible to to cultivate year-round.

This special insulation resistance wire is laid in the soil, which can convert electrical energy into heat energy. Like the floor heating installed at home, the temperature rises steadily and the temperature is uniform. It is very beneficial to the growth and development of watermelon seedlings, and the emergence rate can reach 95% in winter.

Zhou Aifeng, an agricultural technician from a nursery base in Dongtai City, Jiangsu Province: The temperature in the shed can be maintained at around 20°C even at night. The traditional heating method has poor constant temperature effect and heavy air pollution, and the survival rate of melon seedlings is only about 70%.

The extension of the production cycle and the increase in the emergence rate have doubled the number of seedlings emerging in these greenhouses compared with last year, at the current price of USD 0.2 per plant. Only one greenhouse can bring nearly one million yuan of output value. And this production model is also adopted by more and more growers.

The improvement of the quality of seedlings has also directly driven the local watermelon planting. At present, the watermelon planting area in Dongtai has expanded to 4,500,000 hectares, with an annual output of one million tons of watermelons, with a total output value of over USD 0.5 billion, and an average income of over US dollars $24,000 per hectare.

Happy Life in Strawberry Greenhouse Village of Henan

 On January 31, Chinese New Year's Eve, the warm winter sun shone on the strawberry greenhouse. Stepping into the warm, spring-like greenhouse, rows of strawberries are in full bloom, and the red strawberries are "hiding" in the green leaves, looming and mouth-watering.

Villager Eating in the Strawberry Greenhouses

"I'm too busy, so I can only eat the dumplings in the strawberry greenhouse." Wang Xinlin, a big strawberry grower in Luosong Village, Yaojia Town, Zhongmu County, Henan Province, said a little shyly, "Now is the key season for strawberry picking, and the market demand The quantity is large and the price is high, in order to hurry up, we can only spend the New Year in a greenhouse.”

While eating dumplings, Wang Xinlin instructed others to pick them: "You can't pick very ripe ones. The ones that are half-ripe and slightly bluish-white at the tail are the best. They can be stored well and have a high sweetness."

"In the past few days, the temperature has warmed up, and the ripening speed of strawberries has accelerated. We must accelerate the picking." Wang Xinlin said, looking at the strawberries that were already ripe in the shed, "Tomorrow is the New Year, and the market demand is also very large. Seize the opportunity and sell a good one. Price."

Wang Xinlin has planted three strawberry greenhouses this year, and the "loverberry" and "guifei" planted are growing well. From November 2021 to June 2022, he can harvest a lot of crops. The three strawberry greenhouses can earn up to 130,000 yuan.

Luosong Village is a well-known local professional village for the cultivation of greenhouse watermelons and greenhouse strawberries. As early as 20 years ago, the watermelons of Luosong Village were sold in the surrounding cities because of their early maturity and high sweetness. In recent years, the village has vigorously advocated the development of greenhouse strawberry cultivation, which has changed the previous focus on greenhouse watermelons and ignored the potential opportunities in the strawberry market around the Spring Festival. Today, watermelons in greenhouses, strawberries in greenhouses, and two horse-drawn carriages are running side by side.

"In order to make the strawberries more sweet and delicious, the strawberries in the whole village are pollinated by bees to increase the brightness and sweetness of the strawberries, and improve the taste, quality and yield of the strawberries." Song Lulin, secretary of the village party branch, said, "I didn't expect that this year, this year The price of strawberries in China is so high, and the income of farmers has increased by a quarter compared with last year. First, thanks to the replacement of strawberry varieties, the second is the strengthening of technical force. There are specialized technical personnel and sales consultants in the village to raise seedlings, fertilize, plant, One-stop services such as picking and sales. Third, farmers can sell at a good price in the fields.”

Baskets of strawberries were shipped out of the greenhouse, and the buyers who were waiting on the road in the fields directly weighed, paid, and loaded the trucks. They could walk into the homes of citizens early the next morning and serve them on their dining tables.

Seeing the baskets of strawberries turned into smashing banknotes in the field, Song Lulin couldn't hide his joy: "Before and after the Spring Festival, it is the peak season for the sales of strawberries in greenhouses. Because of the continuous cloudy days in the previous stage, the daily output of strawberries is lower than in previous years. In the past few days, the quality of strawberries has been affected by the rise in temperature, and the shape and sweetness have improved, and the purchase price in the field has also stabilized at about 40 yuan per kilogram. There are more than 1,500 strawberries in 367 households in the village. In greenhouses, the average income of each strawberry greenhouse is more than 40,000 yuan, and some families have five or six greenhouses, and the income is 300,000 yuan.”

When the lights are on, the villagers are wearing headlamps and have been picking strawberries in the greenhouse. Wang Xinlin said, "The merchants haven't left yet. Let's pick them quickly so that the merchants can fill up their carts, earn money, and have a happy New Year."

In the greenhouse, farmers are packing red strawberries into boxes. On the road in the fields, merchants are anxiously waiting for the trucks to be shipped out. When the sun sets, the smell of dumplings permeates the greenhouse.

Smart greenhouse adds color to flower cultivation!

The importance of greenhouses in flower production

The importance of greenhouses to flower production has long been known to cultivators. Using greenhouses to cultivate flowers can not only effectively control environmental factors such as temperature, light, humidity, carbon dioxide concentration, and produce high-quality flower products, but also break the seasonal restrictions on flower growth. , to reach the anniversary of production and supply of flowers. In addition, for those flowers that are not suitable for local cultivation, greenhouse facilities can also be used to create suitable environmental conditions for introduction and cultivation. The use of modern greenhouses with various environmental control equipment can maintain a good microclimate environment inside the greenhouse, so that the flowers grow well and have high quality. Israel is because of its advanced greenhouse facilities and spray and drip irrigation technology, which makes export flower products have high market competitiveness.

Nowadays, the role and status of greenhouse facilities in human economic life are becoming more and more obvious. Take Colombian roses as an example, because the atmospheric temperature is too low for more than two months in winter every year, and there are occasional periods when the temperature is too high in summer. Often there is a gap in rose production at these two times of the year. Although it has more than 20 years of cultivation experience, due to the unstable quality and yield of roses, the market during this season has been gradually captured by Ecuador. Therefore, Colombia has to pay attention to the development of facility planting, and constantly develop new greenhouses and supporting facilities. Take international potted flowers as an example, whether it is Canada, the United States or the Nordic countries Denmark and Norway with a cold climate, Colombia and Mexico with a warm climate in Central and South America, Kenya and Zimbabwe in African countries, and even Japan, and Southeast Asia. In Korea and other countries, in order to obtain higher economic benefits, greenhouse facilities are widely used to produce commercial flowers.

It can be said that greenhouses have become a prerequisite for the development of the flower industry. Without advanced greenhouse facilities, it is difficult to produce high-quality potted flowers.

Looking back at the development history of China's flower industry, it can be clearly seen that it is closely related to facility agriculture. The rapid rise of the flower industry in the past 20 years is exactly the 20 years of the rapid development of China's greenhouse industry. The rise of the flower industry in northern China just confirms the importance of modern greenhouse technology for flower production. It is also the widespread promotion of greenhouses that makes New Year's Eve flowers no longer the patent of Cantonese people, but has become a nationwide concept of flower sales time. There are four seasons. Therefore, in order to better develop the flower industry, we must not only rely on the progress of science and technology and the improvement of management level, but also rely on and utilize greenhouse facilities well.

Flower production is increasingly integrated with greenhouses

With the continuous development of the international flower industry and the continuous improvement of modernization and specialization, the combination of flower production and greenhouses has become more and more closely, and the proportion of the facility cultivation area in the world's major flower power plants is also increasing.

As the world's largest flower production and sales country, the Netherlands has a greenhouse area of ​​10,905 hectares, including 4,047 hectares of cut flowers and 1,467 hectares of potted plants, more than 97% of which are Venlo-type glass greenhouses. , fertilizer, gas comprehensive automatic control. The flower industry can create a value of 3 billion euros every year, accounting for half of the total Dutch horticultural output; its flower exports account for 60% of the global market share. With the development of large-scale operation and the change of market positioning, the output value of flowers will further increase. In other countries such as Germany and Israel, 80% to 90% of potted flowers are cultivated and produced in modern greenhouses.

The import and export of flowers in China is also increasing year by year. At present, the total production area of ​​flowers is 334,000 hectares, and the production area of ​​flower facilities (heated greenhouses, solar greenhouses, and plastic sheds) is 47,000 hectares; Nearly 20 billion qualified seedlings were produced. Due to the limited land area, the major cities in the country for flower production have vigorously developed facility cultivation to obtain maximum profits. Taking Beijing as an example, in recent years, flower circulation and sales have grown rapidly. There are 21 flower sales markets with an area of ​​more than 5,000 square meters, occupying 15 hectares of greenhouse area, accounting for 13% of the total greenhouse area; 55% of large greenhouses are used for flower planting and breeding. , renting and the expansion of flowers, forestry, seedlings. Experts predict that during the "Eleventh Five-Year Plan" period, Beijing's large greenhouses will maintain an annual growth rate of 8 to 10 hectares, while the newly built greenhouses are mainly used for the production of flowers and forestry seedlings, high-end potted flowers and fresh cut flowers.

These all reflect the increasingly close integration of greenhouse facilities with the flower industry. It can be said that the development and growth of the flower industry in a country and region is more and more inseparable from the use of modern greenhouses.

What is green house?

With the production of high molecular polymers - polyvinyl chloride and polyethylene, plastic films are widely used in agriculture. 

What is green house?

Greenhouse refers to a room with facilities such as cold protection, heating and light transmission for cultivating plants in winter. In the season that is not suitable for plant growth, it can provide growth period and increase yield, and is mostly used for plant cultivation or seedling raising of warm vegetables, flowers, forest trees and so on in low temperature season. Greenhouses are buildings that control or partially control the environment in which plants grow. Mainly used for non-seasonal or non-regional plant cultivation, scientific research, addition breeding and ornamental plant cultivation, etc.

In the early 1950s, Japan, USA and some European countries successfully applied plastic film to cover the hotbed, and then covered the shed with good results. The greenhouse was originally a special equipment for vegetable production. With the development of greenhouses, the application has become more and more extensive. At present, greenhouses have been used for potted and cut flower cultivation. For example, greenhouses are used for cultivating fruit such as grapes, strawberries, watermelons, melons, peaches and citrus, etc. In forestry production, used for tree seedlings, ornamental trees cultivation, etc. 

Why is a greenhouse called a greenhouse?

Greenhouses originally mean botanical gardens. But with the spread of the term "greenhouse effect", this word has been given a new meaning. As we all know now, greenhouse effect describes the way a portion of the sun's heat is absorbed by the earth's atmosphere and keeps our planet warm at night. And the same process that warms up the earth also takes place in a greenhouse, where the glass (or plastic film) structure will capture the sunlight and the area under the glass/film will heat up. That is why now greenhouse is the widely used term to describe these sheds of plastic film, glass or polycarbonate structures.
