Prevention and control technology of apple replant disease

摘要

Apple replant disease caused the inhibition of tree growth that occur when replanting in the same location,primarily manifesting as slow growth of young apple trees,aggravated the diseases and insect pests,weakened growth of shoots,made root system unhealthy,reduced yield and quality in replanted apple orchards,and caused huge losses to the operators of fruit trees.To solve the problem,researchers at home and abroad have studied the mechanism and prevention measures of apple replant disease,and our research group put forward the prevention and control technology system of apple replant disease after nearly 10 years of research on the basis of previous studies combined with the actual situation in our country,and achieved the desired effect in the main apple producing areas of our country,so as to provide technical support for the renewal of old orchards and the comprehensive prevention and control of apple replant disease.
