In fact, from the point of view of the name, we must not be unfamiliar with the greenhouse insert protection net. It must be used to release insects, but is the function of the insert protection net used to prevent insects? Let's take a look at the other effect.
We don't need to explain the feature of insect control in detail. Everyone will understand that it is used to prevent those pests. For these pests, we will not explain much here. In addition to the role of insect control, it also has the functions of disease prevention, temperature regulation, and strong light shielding.
Generally, the insect protection net is often used in summer. The high temperature in summer is also the growing season for many vegetables, and it is also the season when insects are active. The bacteria in this season are also very active. Generally, these bacteria are disasters for vegetable cultivation. Sex, the main pathogen comes from aphid-borne diseases. With the insect protection net, the bite of insects is isolated, so that the pathogen cannot infect vegetables.
Many people say that we can understand insect and virus prevention, so why does it also have the effect of blocking strong light and adjusting the temperature? The summer sunshine is the most prosperous and the most dazzling. The intensity is very high. The growth of vegetables is not a good thing for growers, and the color of the inspect protection net is diverse.
We can completely choose black or dark gray as shading in summer, and we have data showing that in July-August, in the 25-mesh white insert protection net, the temperature in the morning and evening is the same as that of the open field, and the temperature of the sunny day is higher than that of the open field at noon. about 1°C lower. From March to April in early spring, the temperature in the shed covered by the inspect protection net is 1-2°C higher than that in the open field, and the temperature in the 5 cm ground is 0.5-1°C higher than that in the open field, which can effectively prevent frost.
