Insect nets have the function of both shading and pest control, and are a new type of material for preventing vegetable pests in fields. Insect nets are mainly used for nursery and cultivation of summer and autumn cabbage, Chinese cabbage, summer radish, cabbage, cauliflower, and solanaceous vegetables, melons, beans and other vegetables, and can increase the emergence rate, seedling rate and seedling quality. Now we will introduce the use of insect nets as follows:


(1) The insect nets shall be directly covered on the large scaffolds, compacted with soil or bricks around them, and compacted on the net with a laminating line, used in conjunction with the laminating line and the membrane coiler, leaving the main door uncovered. (2) Using bamboo or steel rods to be bent into small arches, inserted in Daejeon-myeon, covering the insect-proof nets on the arches, and then watering them directly on the net until harvesting is not revealed. . (3) Cover with a horizontal scaffold.

Coverage growth period

Insect nets have less shading, and they do not need to be covered at night or exposed at the front cover. They should be covered throughout the entire period, and pests are not allowed to invade. In order to receive a satisfactory pest control effect.

Soil disinfection

After harvesting, the residue and weeds of the former hoe were removed from the field in time and burned in a concentrated manner. Ten days before the construction of the shed, the flooded vegetable fields were simmered for seven days, drowning the eggs and aerobic pathogens of the surface and underground pests, and then removing water, allowing the sun to dry for 2-3 days, and spraying pesticides across the field to sterilize and kill them. insect. At the same time, the perimeter of the insect net must be tightly sealed to prevent insects from sneaking into eggs. When the small shed is covered and cultivated, the arch shed should be higher than the crops to prevent the leaves from sticking to the insect nets to prevent pests such as the yellow stripe from outside the net to feed on the leaves and spawn on the leaves.

The right aperture

Pay attention to the aperture when buying insect nets. For the production of vegetables, 20-32 mesh is appropriate, and the width is 1-1.8 meters. Black insect nets are available.

supporting measures

In the covering and cultivation of insect nets, it is necessary to increase the production of organic pollution-free organic fertilizers, use heat and disease resistant insects, biological pesticides, and non-polluting water sources, and adopt comprehensive measures such as micro-injection technology to produce pollution-free quality vegetables.

Careful care

After the use of insect nets in the field, they should be promptly received, washed, dried and rolled to extend the service life, reduce depreciation costs, and increase economic efficiency.

Insect network technology

Insect nets are a new type of agricultural cover material. It uses high-quality polyethylene as raw material, adds anti-aging, anti-ultraviolet and other chemical auxiliaries, and is made by drawing and weaving. It is in the form of window screening and has the characteristics of tensile strength, heat resistance, water resistance, corrosion resistance, non-toxic and tasteless, etc. The correct storage life can reach about 3-5 years. In addition to the advantages of shading nets, the Vegetable Insect Exclusion Network is the most important feature of its ability to prevent insects and disease, significantly reduce the amount of pesticides used, is a key technology for pollution-free vegetables, is a simple, scientific and effective pest control measures.
