Temperature Environment Under Cover

Abstract

Temperature is another important environmental condition for plant growth. The temperature of the plant environment can be modified by cover the area. In the daytime, the main energy source is, of course, the sun, and its energy is stored in the soil. The transmissivity of the film used for covering is an important factor in getting a large amount of energy into the soil surface. At night, the energy source is thus the soil layer. The main heat loss from the surface is due to long wave radiation, and the emissivity of the cover is a key factor in this.
