Precautions for the use of insect nets



black shading net factory ( https://www.cnsunshadenet.com/product/shade-net/dhzy2080.html ) has many types of insect-proof nets, such as vegetable insect-proof nets, greenhouse insect-proof nets, fruit tree-proof nets, etc. Because of its simple use, easy operation and obvious effect, it is deeply favored by everyone. But don't be sloppy when applying, pay attention to the following points:

(1) It must be covered throughout the reproductive period

Only full reproductive period coverage. Do not give the opportunity for pest invasion, in order to effectively prevent pests. Generally, vegetables with a short growth period are covered, and the net must be covered after the base fertilizer is applied. The organic fertilizer can be used only after it is fully decomposed. After the shed is covered with insect-proof nets, water is poured directly on the nets, and the nets are not removed until harvesting.

(2) Select the appropriate specifications

The specifications of the insect net mainly include aperture, wire diameter, color, width, etc. In particular, the aperture, too few meshes, and large mesh can not achieve a good insect-proof effect; too many meshes and small mesh, although insect-proof, increases the cost of the insect-proof net, and also reduces the light transmittance and air permeability of the greenhouse. At present, the recommended mesh in production is generally 24-30 mesh, the wire diameter is 0.14-0.18 mm, the width is 10-15 meters, and it is white. If you need to enhance the shading effect of the insect net, you can choose a black insect net. The silver-gray insect net is very effective for aphid avoidance.

(3) Soil disinfection and chemical weeding before mulching

It is an important supporting measure for insect-proof net covering cultivation. It must kill the pests in the soil and cut off their transmission routes. The insect-proof net is tightly compacted with soil pressure around it, and is fastened with a lamination line.

(4) Choose heat-resistant varieties

Insect-proof nets are generally used for delayed cultivation of summer vegetables, cabbage cultivation and early cultivation of autumn vegetables. During this period, the temperature is relatively high, and some insect-proof nets will increase the ground temperature and temperature, so heat-resistant varieties should be selected.

(5) Pay attention to preventing rain and waterlogging

Insect-proof net covering cultivation is generally in the rainy season, so deep trenches and high furrows should be used, and the trenches should be matched, which can drain and irrigate to prevent rain and waterlogging.

(6) Use with insecticidal lamps

Should use yellow board to attract aphids, frequency-vibration insecticidal lamps and other supporting insect control technology in the production period is long, such as the production of cowpea, tomato and other vegetables, when using the insect-proof net covering technology, should be matched with yellow board to attract aphids, frequency vibration type insecticidal lamps and other technologies.

(7) Pay attention to closing the door

Large and medium-sized sheds and greenhouses must be entered through the door for agricultural operations. Insect-proof nets must be installed, and the door must be closed immediately after entering and leaving.

(8) Proper use and storage

Check the damage of the plastic netting manufacturer's （ https://www.cnsunshadenet.com/product/building-net/ ） insect net at any time, and plug the loopholes and gaps in time. In case of strong winds, you need to pull up the pressure network cable to prevent the wind from opening the net. After the insect net is used in the field, it should be collected in time, washed, dried, rolled and stored to prolong its service life and reduce the cost of use.
