The necessity of using shading nets in summer
Some consumers believe that the function of a sunshade net is only necessary when the temperature is low in winter or early spring, and not when the temperature is high in summer. Below, the sunshade net manufacturer will provide you with specific answers.
Sunshade nets have the functions of blocking light, rain, moisturizing, and cooling. The summer weather is hot, and prolonged strong direct light exposure is very detrimental to some crops, such as shiitake mushrooms, edible mushrooms, medicinal herbs, and other protective planting crops. Therefore, when planting these vegetables and medicinal herbs in summer, it is necessary to use shading nets. The application of shading nets is currently expanding in the north, and it is necessary to use them in summer vegetable seedling cultivation or cultivation of valuable medicinal materials to avoid the harm of high temperature and the spread of diseases and pests.
The use of shading nets in the south has become more widespread. There is a saying that "the southern summer is black", which means that shading nets cover a large area of southern fields, making the southern land appear as black.

Discussion on the Humidification Performance of Sunscreen
The humidification performance of shading nets brings great convenience to agricultural production, and we can plant different vegetable plants based on its humidification performance. Here, the sunshade manufacturer will provide you with a specific introduction.
During the high temperature period, covering should effectively increase the ground temperature, promote crop growth, reduce ground water evaporation and irrigation frequency, and achieve the purpose of insulation and humidity reduction. After covering the sunshade net, due to the cooling and wind prevention, the exchange speed between the air in the covered area and the outside world is reduced, and the relative humidity of the air is significantly increased. At noon, the humidity increase value is the largest, generally increasing by 13-17%. The humidity is high, and the soil evaporation is reduced, increasing the soil humidity. The sunshade net crops produced by the sunshade net manufacturers mainly use plastic film mulching, Prevent the exposure of the hot sun from the impact temperature of rainstorm and the spread of diseases and pests.
The method of using local materials and adapting to local conditions for shading net coverage is adopted. The non drip film greenhouse is selected for seasonal and high light intensity vegetable coverage.

The Effect of Different Colors of Shading Nets on Plants
The different ways in which shading nets are used can affect the growth of plants, and it is unknown that the color of shading nets can also affect the growth of crops. Here, the shading net manufacturer will provide you with a specific introduction.
The effect of shading net covering with four different colors of red net, blue net, silver gray net, and black net on the growth and antioxidant properties of tomato hole plate seedlings. The results showed that the height, stem diameter, leaf area, fresh and dry weight per plant of tomato seedlings covered with shading nets were significantly higher than those without coverage. The seedling strength index of Red Net, Blue Net, and Silver Grey Net increased by 41.2%, 15.4%, and 55.2% respectively, while Black Net decreased by 9.7%. Shading net coverage reduced the MDA content, SOD and CAT activities in tomato seedling leaves, and there was no significant difference in POD activity among other treatments except for the blue net.
Moreover, due to the different colors of sunshades, their production speed and output vary. Therefore, consumers should not blindly choose and follow the advice of professional sunshade manufacturers if they do not understand.
