Promote Agricultural Multi-span Steel-frame Greenhouses

 Since 2021, in order to shoulder the political responsibility of grain production and stabilize the planting area of ​​double-cropping rice, the Leiyang local Government in central China has issued the "Leiyang City 2021 Agricultural Multi-span Steel Frame" according to the current situation of spring ploughing production in our city and the subsidy policy for the purchase of live agricultural machinery. Greenhouse Purchase Subsidy Pilot Implementation Plan", arranges special accumulation funds, fully promotes the application of agricultural multi-span steel frame greenhouses, and strives to make up for the shortcomings of early rice facility-based seedling rearing to "escort" grain production.

Up to now, Leiyang City has installed and put into use a total of 13 agricultural multi-span steel frame greenhouses, covering 11 towns and towns, with a total area of ​​36,903 square meters. The standard is 26 yuan/㎡), the provincial subsidy fund is 295,224 yuan (the subsidy standard is 8 yuan/㎡), and the accumulative subsidy fund at the same level is 738,060 yuan (the subsidy standard is 20 yuan/㎡). Leverage agricultural machinery professional cooperatives and users to invest about 2 million yuan.

Use of Insect-proof Nets in Greenhouses

Why should we install insect nets in greenhouses? There are two main reasons. In addition to promoting the growth of greenhouse vegetables, it also has many benefits for ensuring the environment in the greenhouse. Although the role of insect nets is obvious, improper installation and use will also have side effects.

The purpose of installing agricultural insect-proof nets in greenhouses

(1) Pest control After covering the insect control net, it can basically avoid various insect pests such as cabbage caterpillars, diamondback moths, and aphids.

(2) The anti-disease and insect-proof net can play a role in preventing diseases, especially the spread of aphids, cutting off the transmission of pests, especially the spread of aphids, greatly reducing the incidence of virus diseases, and avoiding the spread of viruses to agricultural greenhouses. with catastrophic consequences.

(3) The temperature-controlling insect-proof net can adjust the temperature and soil temperature of the agricultural greenhouse. In the hot summer, the greenhouse is covered with a white insect-proof net, and the temperature in the greenhouse in the morning and evening is the same as that in the open air, but at noon is about 1°C lower than that in the open air; Covering the black insect net in the season can achieve the effect of heat preservation and effectively reduce frost.

(4) Humidity control The insect-proof net can prevent part of the rainwater from falling into the agricultural greenhouse, reduce the humidity in the field, reduce the incidence of disease, and reduce the evaporation of water in the greenhouse on sunny days.

(5) Shading light In summer, the light intensity is large, and the strong light will inhibit the vegetative growth of vegetables, especially leafy vegetables, and the insect-proof net can play a certain role in shading and shading.
