(3) Light is needed for a series of important life activities, such as stomatal opening and closing, water absorption, flower bud formation and so on.
2. Treatment in different seasons
Mainly talk about winter and summer. The temperature in winter is very low, so it should be exposed to as much light as possible so that it can survive the winter safely. However, the light is too strong in summer, but it can not be without light. Therefore, it is generally chosen to receive light before 7 o'clock in the morning, when the light will be very soft and will not burn the leaves. After seven o'clock, the shading is about 50% to 90. In spring and autumn, scattered light is fine.
