2. Soil and fertilizer management. Rational collocation of organic fertilizers such as nitrogen, phosphorus and potassium with inorganic fertilizers. The suitable ratio of nitrogen, phosphorus and potassium is 4∶2.5∶3, and the organic fertilizer accounts for more than 60% of the total fertilization. Fertilization in young orchards should be thin and diligent, 4~5 times a year, with nitrogen and phosphorus as the main fertilizer. Adult trees can be fertilized three times a year, the first time with quick-acting fertilizer, the second time with quick-acting nitrogen fertilizer combined with organic fertilizer and phosphate fertilizer, and the third time with slow-acting fertilizer.
3, plastic trimming. Shaping method: after planting, in the first round of lateral branches (30~60 cm from the ground), three evenly distributed branches are selected as the first layer of main branches for cultivation, and two branches are selected as auxiliary branches. Pruning methods: thinning branches, cutting off pests and diseases, crossing branches and overlapping branches, cutting off short leafless branches, retracting drooping branches and weak branches, etc.
4. Flower and fruit management. Measures to promote flowers: strengthen fertilizer and water management in infancy, and take reasonable measures to promote flowers in the second year of growth. Sparse flowers and fruits: strong trees are sparse, weak trees are sparse, Ye Qiang is sparse, leaves are sparse late, leaves are early, and the top is removed to stay inside.
5. Fruit packaging: after flowering 1 month, put 2~3 leaves into paper bags, and spray thiophanate-methyl and pyrethroid pesticides once before. Bagging sequence: first up, then down, first inside and then outside.
6, fruit harvesting: carefully cut off the fruit stalks in your hands, do not scratch the fruit surface, bruise the fruit, after harvesting, put it into a padded fruit basket for single fruit packaging.
