How to Use Insect Netting


The insect-proof net not only has the function of shading, but also has the function of preventing insects. It is a new material for preventing insect pests in field vegetables. Insect control net is mainly used for the seedling and cultivation of vegetables such as cabbage, cabbage, summer radish, cabbage, cauliflower, solanaceous fruit, melon, beans and other vegetables in summer and autumn, which can improve the emergence rate, seedling rate and seedling quality. Now the use technology of insect net is introduced as follows:

cover form
(1) Cover the vegetable insect-proof net directly on the greenhouse, press and compact it with soil or bricks around it, fasten it on the net with a lamination line, and leave the front door uncovered. (2) Bend bamboo pieces or steel bars into small arches, insert them on the surface of the field, cover the arches with insect-proof nets, and pour water directly on the nets afterward. The nets are not uncovered until harvesting, and full closed coverage is implemented. . (3) Cover with horizontal scaffolding.

Must cover the entire growing season
Insect-proof nets have less shading, and do not need to be uncovered day and night or the front cover and back cover. It should be covered throughout the entire process, so as not to give pests a chance to invade, in order to receive a satisfactory insect control effect.

soil disinfection
After the previous crop is harvested, the residues and weeds of the previous crop should be moved out of the field in time and burned centrally. 10 days before the construction of the shed, flood the vegetable field with water for 7 days, drown the eggs and aerobic bacteria of the surface and underground pests, and then remove the stagnant water, expose it to the sun for 2-3 days, and spray the whole field with pesticides to sterilize insect. At the same time, the insect nets should be compacted and sealed to prevent pests from sneaking in and laying eggs. When the small arch shed is covered and cultivated, the arch shed should be higher than the crops, so as to avoid the vegetable leaves from sticking to the insect-proof net, so as to prevent the yellow striped flea beetle and other pests outside the net from feeding on the vegetable leaves and laying their eggs on the vegetable leaves.

Choose the right aperture
You should pay attention to the aperture when buying insect nets. For vegetable production, 20-32 meshes are appropriate, and the width is 1-1.8 meters. White or silver-gray insect nets work better. If the shading effect is strengthened, black insect nets can be used.

Comprehensive supporting measures
In the cultivation of insect-proof net covering, it is necessary to increase the application of decomposed and pollution-free organic fertilizers, select heat-resistant and pest-resistant varieties, biological pesticides, pollution-free water sources, and adopt comprehensive measures such as micro-spraying technology to produce pollution-free high-quality vegetables.

well kept
After the insect-proof net is used in the field, it should be received in time, washed, dried, and rolled to prolong the service life, reduce the depreciation cost and increase the economic benefit.

Insect net technology
Insect net is a new type of agricultural covering material. It uses high-quality polyethylene as raw material, adds anti-aging, anti-ultraviolet and other chemical auxiliaries, and is made of wire drawing and weaving. Lightweight and properly stored, the lifespan can reach about 3-5 years. In addition to the advantages of sunshade nets, vegetable insect control nets are characterized by being able to prevent insects and diseases, and greatly reduce the use of pesticides.
