Consumers can choose a suitable sunshade net according to their needs. When choosing, they should pay attention to the color, shading rate, width, and other aspects. Next, let's take a look at the plastic net manufacturer.
The commonly used sunshade nets are black, silver-gray, blue, yellow, green, etc. The two types of black and silver-gray are most commonly used in vegetable covering cultivation. The shading and cooling effect of a black sunshade net are better than that of a silver-gray sunshade net. It is generally used in summer and high-temperature seasons and crops with lower requirements for light and less damage to virus diseases, such as cabbage, baby cabbage, Chinese cabbage, and celery, Cover cultivation of green leafy vegetables such as coriander and spinach. The silver-gray sunshade net has good light transmittance and has the effect of avoiding aphids. It is generally used in early summer, and early autumn, and crops that require high light and are susceptible to viral diseases, such as radish, tomato, pepper, and other vegetables. For frost protection in winter and spring, both black and silver-gray sunshade nets are available, but silver-gray sunshade nets are better than black sunshade nets.
2. Shading rate
Sunshade net can adjust the weft density during the weaving process so that the shading rate can reach 25% to 75%, or even as high as 85% to 90%. In mulching cultivation, it can be selected according to different needs. Covering cultivation in summer and autumn does not require too much light. For cabbage and other green leafy vegetables that are not resistant to high temperatures, a sunshade net with a higher shading rate can be used.
Fruits and vegetables that have higher requirements for light and are more resistant to high temperatures can choose a sunshade net with a lower shading rate. In winter and spring, it is covered with frost and frost protection, and the effect of a sunshade net with a high shading rate is good. In general production applications, a sunshade net with a shading rate of 65% to 75% is generally used. When covering, it should be adjusted according to different seasons and weather conditions by changing the covering time and adopting different covering methods to meet the growing needs of different crops.
The general product range is 0.9 meters to 2.5 meters, and the widest is 4.3 meters. Some manufacturers can also customize according to their needs. At present, the use of 1.6 meters and 2.2 meters are more common. In covering cultivation, multiple splices are often used to form a large-area monolithic covering. It is convenient to open the cover when in use, easy to manage, labor-saving, labor-saving, easy to fix, and not easy to be blown up by strong winds. According to the length and width of the coverage area, sunshade nets of different amplitudes can be selected for splicing. When cutting the sunshade net, the notch should be ironed with a soldering iron. When splicing, the cotton thread should not be used, but nylon thread should be used to increase the splicing firmness.
