Insect net cover cultivation is a new practical and environmentally-friendly agricultural technology that increases yields by constructing artificial isolation barriers on the scaffolds to keep pests out of the net, cutting off the pest (adult) reproduction pathways, and effectively controlling various pests. Then use What are the benefits of insect nets?
1. Social benefits
It has greatly improved the insect and disaster resistance of summer and autumn vegetables, and solved the problem of vegetable shortage that has long plagued vegetable farmers and citizens at all levels. The social effect is self-evident.
2. Economic benefits
Insect-proof nets cover, which can realize the production of vegetables without pesticides or less pesticides, thus saving medicine and labor. The use of insect nets has increased production costs, but due to the long service life of insect nets (4-6 years), long use time within the year (5-10 months), and multiple crops can be used (6-8 can be produced by leafy vegetables) Stubble), the input cost per stubble is low (the effect is more obvious in disaster years). Vegetables have good quality (no or less pesticide pollution), and the yield increase effect is good.
3. Ecological benefits
Environmental issues have received increasing attention. Chemical pesticide control effect is remarkable, but it has exposed many disadvantages. The frequent use of pesticides has caused pollution of soil, water, and vegetables. Poisoning incidents caused by accidental consumption of pesticide-contaminated vegetables occur every year.
Pupae have increased their resistance to pesticides, making it increasingly difficult to control them. Plutella xylostella, Spodoptera litura, and other pests have even developed to the point where they have no cure. Insect-proof mulch cultivation is achieved through physical control.
