Recently, the pear fruit has expanded and matured, the long shoots stopped growing, the leaves were all built, and the tree entered the flower bud differentiation stage. Fruit farmers should pay close attention to weather changes and strengthen the management of pear orchards.
The prevention and control of pests and diseases in the recent stages is frequent, and it is necessary to pay attention to the treatment of pear black spot, black spot and ring disease. The applicable drugs are thiophanate-methyl, flusilazole and carbendazim. After the rain, there is a high temperature, and the pears and red spiders are prone to occur in the field.
After the harvest of fertilizer and water management, 200 grams of urea per tree is applied to improve the quality of flower bud differentiation, and then increase the yield and quality of next year. In combination with the prevention and control of pests and diseases, urea (0.2% to 0.3%) or potassium dihydrogen phosphate (0.3% to 0.5%) is added and sprayed at the time of application. In addition, it is necessary to do a good job of composting the organic fertilizer to make it fully ripe.
