Although the film roots of fruit trees can increase the temperature of the ground and keep the water after watering from evaporating and increase the survival rate, the summer diseases are more unfavorable. The reason is: With the increase in ground temperature in the summer, not only the heat of the soil covered by plastic film can not spread out, but the heat absorption of the agricultural film is enhanced, it is easy to cause root-burning suffocation and death (newly planted fruit trees are more serious). In addition, when the water around the root system is depleted, the agricultural film isolates the surface of the soil and does not come into contact with the recharge of rainwater, which also affects the development of the roots. Therefore, it is not advisable to remove the plastic film if the film is used before the tree has survived or the high temperature has come. Grass is best used in summer.
