A basic introduction to insect proof nets

防虫网 covering culture is a new and practical environmental protection agricultural technology to increase production. By covering the trellises to construct artificial isolation barriers, the pests are excluded from the net, and the propagation path of pests (adult insects) is cut off, so as to effectively control all kinds of pests. Such as cabbage worm, cabbage moth, cabbage moth, aphids, hopping beetle, beet moth, American spot miner, moth will spread and prevent the spread of virus disease harm. It has the functions of light transmission, moderate shading and ventilation, creating favorable conditions suitable for crop growth, ensuring that the application of chemical pesticides in vegetable fields is greatly reduced, making crops of high quality and health, and providing a strong technical guarantee for the development and production of pollution-free green agricultural products.

Insect nets also have the function of resisting natural disasters such as storms, rain erosion and hail attacks. Insect control net is widely used in vegetables, rape and other breeding seed for isolation of pollen into the use, potatoes, flowers and other tissue culture after virus-free shield and pollution-free vegetables, can also be used in tobacco seedling for pest control, disease prevention, physical control of all kinds of crops, vegetable pests of the first choice products. Truly let the majority of consumers eat "cabbage" and contribute to China's vegetable basket project.

Scope of application:
1.Leafy vegetables are vegetables that urban and rural residents like to eat in summer and autumn, with the characteristics of fast growth and short cycle, but there are more pests in open field production, serious pesticide pollution, and citizens do not dare to eat. The use of insect-proof nets can greatly reduce pesticide pollution.
2.Solanum and melon insect-proof nets covered cultivation. The virus disease is easy to occur in summer and autumn in solanum and melon. The application of insect control net can cut off the transmission path of aphids and reduce the harm of virus disease.
3.Raising seedlings. From June to August every year, it is the seedling season of autumn and winter vegetables, and it is also a period of high humidity, heavy rain and frequent insect pests, which is difficult to grow seedlings. After the use of insect nets, the vegetable emergence rate is high, the seedling rate is high, the seedling quality is good, so as to win the initiative of autumn and winter vegetable production.

Application effect:
1. economic benefit. Insect-proof net coverage can realize the production of vegetables without spraying or less spraying, thus saving medicine, labor and cost. Although the use of insect nets increases the production cost, because the insect nets have a long service life (4-6 years), a long use time (5-10 months) in the year, and can be used in multiple crops (6-8 crops can be produced by planting leafy vegetables), the input cost per crop is low (the effect is more obvious in disaster years). Good vegetable quality (no or less pesticide pollution), good yield increase effect.
2.Social benefits. Greatly improve the pest prevention and disaster resistance of summer and autumn vegetables, solve the problem of vegetable shortage that has plagued leaders at all levels for a long time, vegetable farmers and citizens, and its social effect is self-evident.
3.Ecological benefits. Environmental problems have attracted more and more people's attention. The effect of chemical pesticides is remarkable, but many drawbacks are exposed. The frequent use of pesticides has caused the pollution of soil, water and vegetables, and poisoning incidents have occurred every year due to eating vegetables contaminated by pesticides. The resistance of pests is increasing, and the prevention and control is becoming more and more difficult, and the pests such as Diamondiella moth and Noctura terrestris even develop to the point of no medicine. The purpose of insect control is achieved through physical control.
