| Abstract: | The pit covered with film can raise the temperature of the soil and prevent water evaporating from soil. The temperature of the soil between 5～20 deep can be raised 3℃ averagely with the maximum increase on the surface of the pit when film covered in April or May of the year. Water content in soil within 20 deep increases 9 4%～16 9%between last ten days of April and Oct. Survival rate and height of trees are 46 2% and 20 9% greater respectively than without covering in the autumn of the third year. |
