200 Meters Silver Grey Insect Mesh Netting For Adjust Soil Temperature

What you need to know before using insect nets

Insect nets are a new type of material used to prevent vegetable insects in the field. They can both shave and prevent insects, and they have a wide range of applications. We need some understanding of the pest network when we use it. First of all, we have to understand the coverage period of the insect net. Because of the holes in the insect-proof nets, there is not much shading, and it is not necessary to cover them at night in the daytime. It is better to cover the whole process so that the pests do not have an opportunity to invade, so as to receive satisfactory results.

Insect-proof net is a new type of cover material, which is made of polyethylene (PE) as a raw material and is woven and woven to form a window screen. With high tensile strength, UV resistance, heat resistance, water resistance, corrosion resistance, aging resistance and other properties, non-toxic and odorless, the service life of 3 ~ 5a [1]. In order to study the application effect of insect nets on small green vegetables, this experiment was specially conducted. 1 Materials and Methods 1.1 Species of test materials: Dwarf yellow, sowing volume is 22.5kg/hm2. Insect nets and control agents: 5% of CPT is produced by the Japan Petroleum Corporation; 2.5% of deltamethrin EC is imported from France.

The experimental design pest control test set up five treatments: (1) 0.45mm (40 mesh) aperture insect nets; (2) 0.6mm (30 mesh) aperture insect nets; (3) 5% Suppository EC 2000 times; (4) 2.5% deltamethrin emulsifiable concentrate 2000 times; (5) control. Repeat 3 times, randomly arranged. The shelter net community was bent into bamboo sheds, each plot was 7.0m×1.67m, and the ditch width between the plots was 0.5m.

There is also an insect screen to choose the appropriate aperture size. We must pay attention to the size of the aperture when choosing to purchase insect nets. In general, vegetable production mainly uses 20-32 mesh, which is about 1 to 1.8 meters wide. In addition, black insect nets can be used. Also understand the coverage of the insect net. You can use steel bars or bamboo pieces to be bent into small arches, inserted into the surface of Daejeon, and then cover the insect nets on the arches. Watering can be poured directly on the net, and the nets can be uncovered when harvesting. Fully enclosed coverage.

In addition, horizontal scaffolding can also be used. During the covering and cultivation process of insect nets, it is best to apply pollution-free organic fertilizer, select resistant insects, use biological pesticides, and water sources that are not polluted. Insect nets should be removed promptly after the end of field use. Blow dry, wash, roll well. Maximize the service life, reduce the depreciation cost, and bring more economic benefits
