How to distinguish the shade cloth and anti insect net
Insect nets and sunshade nets are both products that can be applied to agricultural planting, and both can play a role in protecting and covering crops. So what is the difference between these two products? Let's talk about the difference between them.
1. Function:
(1) The shading rate can reach 35% to 75%, and the cooling effect is obvious;
(2) Resist storms, rainstorms, hail and other disasters;
(3) Reduce transpiration, water retention and drought resistance;
(4) The control effect is 89% to 100%, and the control effect is 88.9% to 95.5%.
2. Precautions for use:
(1) Cover before sowing, no need to open the net, but pay attention to open the net at night after emergence. After transplanting and sowing, the seedlings can also be covered to slow down the growth of the seedlings, but they should be treated day and night.
(2) Melons, eggplants, beans, etc. harvested in spring and summer can be refrigerated. After planting, they can be covered with small arched sheds or large arched sheds, and small arched sheds can be covered. If the small arches covered with film are covered with shading nets, the frost protection is good, but cover them day and night.
(3) The black net is suitable for vegetables with weak light demand, and the white net is suitable for vegetables with light preference. The black net is suitable for short-term concealer, while the white net is suitable for the whole growing season. After covering the black nets, the nets should be opened and covered in strict accordance with the vegetable variety and vegetable growth period, and the use of white nets is not strictly required.
(4) In summer, it is mainly covered by sunny days at noon, and can be removed in the morning, evening and cloudy days. On sunny days, the nets are generally covered from 9am and the doors open at 3pm.
Insect-proof net is a new type of covering material, which has the functions of shading and insect-proof.
1. Covering method:
(1) The greenhouse is covered. Covering the scaffolding improves the utilization of the scaffolding.
(2) The shed is covered. It has the advantages of less investment, easy promotion and application, and can achieve the effects of insect control, disaster prevention and fresh-keeping. However, the height of the trellis should be higher than the height of the crops to prevent the leaves of the crops from moving when they encounter feeding pests during the incubation period, which is higher than the height of newly planted vegetables.
2. Protection effect:
(1) It covers the entire growth period. The product has less shade and requires no covering during the day or night, nor does it require a front cover. Covering the whole process, preventing pests from invading, and achieving satisfactory control effects. The ends are compacted with bricks or earth blocks to prevent them from being blown away by the wind.
(2) Select the appropriate criteria. The standards of insect nets mainly include waviness, aperture, wire diameter, color, etc. In particular, the aperture and density are usually calculated according to the mesh number. If the number of grids is too small, the grids will become too large to keep out insects; but if there are too many grids, the grids will be small, which will increase the cost.
