Appropriate light intensity and temperature are necessary conditions for plant growth. In general, the stronger the price of sunshade nets, the higher the temperature. In order for plants to be safe for the summer, tradeoffs and tradeoffs can only be made between temperature and light intensity. Usually choose to increase the shade, and reduce the temperature by increasing the shade or the number of layers of the shade net. For example, the production of Impatiens in New Guinea generally does not require shade or only a layer of silver shade nets of 50%, but in the high temperature season of summer, an extra layer or even two layers of shade nets should be added to reduce the temperature.
Pay attention to the following two points when using sunshade nets:
1. For general flowers, the price of the shade net is better than that of black.
2. It is recommended to increase the number of layers of the shading net, instead of directly replacing the shading net with a high shading rate. The price of shading nets At the same time, it is recommended to adopt a combination of fixed shading nets and openable shading nets. In this way, it is flexible and can be closed in a rainy day or when the temperature is relatively low in the morning and evening, so that the plant can adjust the light under different temperature conditions, which is beneficial to plant growth.
