1. Vegetable farmers who use HDPE shading factory nets are very easy to buy nets with higher shading rates when purchasing shading nets. They will think that the higher shading rates are cooler. However, if the shading rate is too high, the light in the shed is weak, the photosynthesis of crops is reduced, and the stems are thin and leggy, which reduces the yield of crops. Therefore, when choosing a shading net, try to choose a shade with a lower shading rate.

　　2. When purchasing sunshade nets, try to choose large HDPE sunshade net factories and products with guaranteed brands, and make sure that products with a warranty of more than 5 years are used in the greenhouse.

　　3. The heat shrinkage characteristics of the sunshade net of HDPE sunshade net factory are easy to be ignored by everyone. As it shrinks, the shading rate also increases. Therefore, the thermal shrinkage characteristics should be considered when fixing with the card slot.

　　There are two types of shading net covering methods: full coverage and pavilion-type coverage. In practical applications, pavilion-type coverage is used more because of the smooth air circulation and better cooling effect. The specific method of the HDPE sunshade net factory is: use the skeleton of the arch shed to cover the sunshade net on the top, and leave a 60-80 cm ventilation belt on it. If covered with a film, the sunshade net cannot be directly covered on the film, and a gap of more than 20 cm should be left to use the wind to cool down.
