Plain weaving 1.3*1.3mm 2-3%UV White Screen Mesh Net For Crop Cover
In addition to pest control and prevention of insect disease network, there is a certain role in regulation, then this regulation is to regulate what? How is it adjusted? What kind of benefits does this regulation have to the crop growing environment in greenhouses?
First of all, the role played by the insect control network is actually the regulation of temperature and soil temperature in the shed, as well as the regulation of air humidity and soil moisture. In short, it is the adjustment of temperature and humidity. The
Secondly, through experiments, we found that during the hot July-August, in the 25-mesh white insect net, the morning and evening temperatures were equal to the open air, and the sunny days were about 1 degree lower than the open ground. In the early spring and March-April, the temperature of the insect net covering the shed is 1-2°C higher than the open air temperature, and the temperature of 5cm is 0.5-1°C higher than the exposed ground.
Thirdly, through the analysis of experimental results, we can summarize the effect of insect nets on the environment within the shed, that is, it can effectively reduce the temperature in the summer and effectively prevent frost in the winter; when it rains, it can reduce the amount of precipitation in the net room, and the sunny days can reduce. The amount of evaporation in the net room.
