First, apply more organic fertilizer to ensure at least one catty of fruit yield, apply two catties of organic fertilizer, and pay attention to balanced fertilization. 2. Secondly, load and adjust the fruit yield reasonably. The rot disease is serious, and the yield per mu does not exceed 4000 kg. To increase the yield, the tree should be kept at about 6000 kg after recovery. 3. The best medicine to cure the lesion in time is methylthionaphthylacetic acid (the wound heals fastest). Secondly, bacterial toxins should be careful not to use a mixture of sulfur and stone (the latest research results are completely ineffective), and spray garden cleaner Schneider (amobam) before germination. 4. heal the big wound.
