How to use the insect net:
Soil disinfection and chemical weeding before covering is an important supporting measure for insect net covering cultivation. It is necessary to kill germs and pests remaining in the soil and block the transmission of pests. When the small arch shed covers and cultivates vegetables, the height of the arch shed should be higher than the height of the vegetables, so as to prevent the vegetable leaves from sticking to the insect-proof net, so that the pests outside the net can eat the vegetable leaves and lay eggs on the vegetable leaves. Check the damage status of the insect net at any time, and plug the loopholes and gaps in time.

During the growth period, there is not much shading of the insect-proof net. It does not need to be covered day and night, or it can be covered in the whole growth period. Generally, the wind power does not need to be pressed. In case of strong winds of grade 5-6, the network cable needs to be pressed to prevent it from being opened by the wind.

Selection of suitable specifications According to the different types of vegetables and cultivation seasons, select the width, aperture, wire diameter, color, etc. Among them, the important thing is the aperture, the aperture mesh is too small, the mesh is too large, the mesh is small, and the insect-proof effect is good, but the shading is too much, which is not good for the growth of vegetables. Generally, 30 mesh is more suitable.

When the temperature is high, the temperature inside the net is higher than that outside the net. Therefore, when the temperature is particularly high from July to August, the frequency of watering can be increased to cool down with humidity.

Insect net cover method:
Floating surface cover For water spinach, amaranth, cabbage and other leafy vegetables, from sowing to harvest, directly cover the green insect-proof net on the border surface, and cover the green insect-proof net for cabbage, early cauliflower, etc. 20 fields after planting, not only can effectively prevent twill The damage of noctuid moth and beet moth can also prevent violent storms and reduce leaf damage.

The use of shed masks is the most widely used method of masking. The shape of the small trellis varies according to the width of the border, and it can be made into a small flat shed or a small arched shed. This method requires less investment, is easy to implement, and can be sprayed from outside the shed.

The greenhouse is covered with a greenhouse, which is completely closed and covered with an insect-proof net, and the vegetables are cultivated in it.
