How to choose summer sunshade net
1. Color. Commonly used sunshade nets are black, silver-gray, blue, yellow, green, etc., and black and green are the most commonly used in vegetable cover cultivation. The shading and cooling effect of the black sunshade net is better than that of the green sunshade net, which is generally used for the planting of leafy green vegetables such as cabbage, baby cabbage, Chinese cabbage, celery, coriander and spinach in autumn during the summer heat season and the crops with low lighting requirements and less harmful virus diseases. The green sunshade net has good light transmission, and is generally used in early summer, early autumn season and crops with high light requirements and easy to be infected with viral diseases, such as radish, tomato, pepper and other vegetables. For winter and spring antifreeze coverage, black and green sunshade nets can be used, but green sunshade nets are better than black sunshade nets.
2, shading rate. In the process of weaving, the sunshade net can be adjusted by the weft density, so that the shading rate can reach 25% to 75%, and even as high as 85% to 90%. It can be selected according to different needs in mulch cultivation. Summer and autumn mulching cultivation, the requirement of light is not too high, and the cabbage and other green leafy vegetables that are not resistant to high temperature can choose the sunshade net with high shading rate. For fruits and vegetables with higher lighting requirements and higher temperature resistance, sunshade nets with lower shading rate can be selected. Winter and spring anti-frost coverage, with a higher shading rate of the sunshade net effect is good. In general production applications, sunshade nets with a shading rate of 65% to 75% are generally used. When using the cover, it should be adjusted according to different seasons and weather conditions by changing the time of covering and taking different ways of covering to meet the growth needs of different crops
3. Width. The general product range is 0.9 meters ~2.5 meters, the widest up to 4.3 meters, we can also be customized according to needs. At present, the use of 1.6 meters and 2.2 meters is more common. In the cover cultivation, many pieces of splicing are used to form a large area of the whole cover, which is convenient to cover when used, easy to manage, labor saving, labor saving, and easy to fix, and not easy to be blown up by strong winds. Sunshade nets of different amplitude can be selected according to the length and width of the coverage area.
