What matters should be paid attention to when building vegetable greenhouses in rural areas?

The benefit of greenhouse vegetables is increasing year by year. Driven by the demonstration base, greenhouse construction is in full swing all over the country. However, due to uneven technology, greenhouse construction has left many loopholes. Through practice and theory, the following technical experience of greenhouse construction is summarized: the optimum width of greenhouse construction. The sixth generation greenhouse with warm winter and high temperature is a greenhouse with high standard at present, but it is the most economical and suitable for construction all over the country. Generally, the width of each shed is 25 meters. The length varies from 80- 120 meters, but some farmers set the greenhouse too narrow to save land, and the greenhouse in front is too cool for the back in winter, which makes the first half of the greenhouse stay in the dark for a long time, which seriously restricts the yield of vegetables. Expert guidance: Leave 4-5 meters in front of the shed. At present, the front of many greenhouses is flat, so when it rains heavily, rainwater will flow into the greenhouses, which has a great impact on the production and life of the greenhouses. Therefore, a drainage ditch should be left in front of the greenhouse to facilitate drainage in summer and snow in winter. Expert guidance: the ditch is 0.5 meters deep and 3 meters wide. Protection measures of greenhouse The protection of greenhouse walls is very important. Unfavorable protection will destroy the greenhouse and cause great losses. Expert guidance: After the top and back slopes of the greenhouse are leveled, wrap a layer of plastic paper, preferably EVA film, which can prolong the service life, and then wrap a layer of non-woven fabric. Be sure to compact the non-woven fabric. Slope inside the greenhouse wall In order to save land, many farmers design the slope inside the greenhouse wall too small, and some even reach a vertical state, which is not conducive to the wall safety during the greenhouse construction. Expert guidance: According to the local soil quality, the slope of sandy loam should be 9- 10 degrees.
