Application range and effect of insect control net in greenhouses

 Application scope of greenhouse insect control net
(1) Leaf vegetable cultivation with insect control net. Leaf vegetables are very popular among urban and rural residents in summer and autumn. They have the characteristics of fast growth and short cycle. But the open production of pests, pesticide pollution is serious, the public dare not eat. Pesticide contamination can be greatly reduced by covering cultivation with insect nets.
(2) Planting eggplant and melon with insect control nets. Eggplants and fruits are prone to disease in summer and autumn. After the application of insect control net, cut off the aphid transmission path, reduce the harm of the disease.
(3) Raising seedlings. Every year from June to August, is the autumn and winter vegetable seedling season, but also high humidity, heavy rain, frequent insect pests period, seedling cultivation is difficult. After using insect control net, vegetable emergence rate is high, seedling rate is high, seedling quality is good, won the initiative of autumn and winter vegetable production.

Application effect: 
 (1) Economic benefits.  With insect-proof net covering, vegetable production can be realized without or with less pesticide, saving medicine, labor and cost.  Although the use of insect control net increases the production cost, it has a long service life (4-6 years), a long use time (5-10 months), can be used for a variety of crops (planting leafy vegetables can produce 6-8 crops), and the input cost of each crop is low (especially the effect in disaster years).  Good vegetable quality (no or less pesticide pollution), good yield effect. 
 (2) Social benefits.  It has greatly improved the pest control and disaster resistance ability of vegetables in summer and autumn, and solved the problem of vegetable shortage that had long troubled leaders at all levels, vegetable farmers and citizens.  The social effect is self-evident. 
 (3) Ecological benefits.  More and more people are concerned about environmental problems.  The effect of chemical pesticide control is remarkable, but it exposes many disadvantages.  Frequent use of pesticides has caused pollution of soil, water and vegetables.  Every year, poisoning incidents caused by eating vegetables contaminated with pesticides occur from time to time.  Pest resistance is becoming stronger and more difficult to control.  Pests such as diamondback moth and noctuidae have even developed to the point of no cure.  Insect control mulching culture is achieved by physical control
