1. Economic benefits. Insect prevention net coverage can achieve vegetable production without or less pesticide, thus saving medicine, labor and cost. The use of insect-proof nets increases the production cost, but because the insect-proof nets have a long service life (4-6 years), a long service time (5-10 months) in the year, and can be used in multiple crops (planting leafy vegetables can produce 6-8 crops), the input cost of each crop is low (the effect is more obvious in disaster years). Good quality (no or less pesticide pollution) and good yield increase effect.
2. Social benefits. It has greatly improved the pest prevention and disaster resistance ability of vegetables in summer and autumn, and solved the problem of vegetable shortage that has plagued vegetable farmers and citizens for a long time. Its benefits are self-evident.
3. Ecological benefits. Environmental problems have attracted more and more attention. Chemical pesticides have significant control effects, but they expose many drawbacks. The frequent use of pesticides has caused pollution of soil, water and vegetables. Every year, poisoning incidents caused by eating vegetables and fruits contaminated by pesticides occur from time to time; Pests are more resistant to pesticides and more difficult to control. The diamondback moth, spodoptera litura and other pests even develop to the point where there is no medicine to cure. Insect prevention and cover cultivation is achieved through physical control.
