Lei Zongzhong, professor of Yangling Vocational and Technical College, replied: There are two reasons for the problems in the leaves. First, farmers may spray pesticides in orchards under high temperatures, causing phytotoxicity in orchards. If this is the case, a kind of plant called "Baihu" plant grown in Germany can be sprayed on the orchard to strengthen the phytotoxicity. The second possible cause is a problem with kiwifruit roots, such as root rot. If this is the case, a bio-fertilizer may be applied to the fruit trees and some rooting powder may be added, wherein the bio-fertilizer kills the root bacteria, and the rooting powder gives the fruit tree a new root system.
In addition, in the same orchard, the root knots of some tree roots that do not develop branches, leaves, or fruit are also used in the prevention and treatment of biological bacterial fertilizer and rooting powder.
