First, wipe the bud According to the principle of “early shoots, timely picking of the heart, and short cutting of long branchesâ€, combined with the condition of tree vigor, pruning is performed several times during the growth period to achieve the purpose of high yield and stable production. During the sprouting period, the buds that are not in the right position or too dense are erased as soon as possible. For the fruiting branches of mature orchards, leave 8-10 leaf topping above the result site. The second branch germinated after the first topping, leaving 3-4 leaves topping; for the 3rd branch of germination, leave 2-3 leaves topping; leave 10-15 for cultivable leggy or vegetative branches. Sliced ​​topping. The pest branches and thin branches are generally removed from the base. Second, flowering pollination early flowering in late April, full flowering in early May and late flowering in late May. In the flowering period, it is even rainy and poor pollination. Artificial pollination is required. The specific method is: male flocks are collected in advance at the flowering stage, and the pollen sacs are removed and placed at room temperature of 25° C. After an hour and night, the pollen sac opens to collect pollen. Pollination was conducted in two batches during the female flowering period, and the flower pollination effect on the day was good. Third, timely sparse fruit and thinning should be carried out 10-15 days after flowering, in accordance with the principle of "retaining good and bad, leaving large and small, leaving thin and dense, leaving the middle to go to the base", remove deformed fruit, weak fruit, Overlapping fruit, disease and fruit, generally 1-2 fruits in short fruiting branches, 3-5 fruit in middle fruiting branches, and 4-6 fruit in long fruiting branches.4. Caused by a large number of flowers and fruit drop, available 50% zilosulfuron suspension 8000-10000 times, 5% stuck 1000-1500 times solution, spray every 10 days, even spray three times.6-9 months, spraying 80% Dasheng M45 WP 800 times, 40% Fuxing EC 6000-8000 times, 1% Zhongsheng water 200 times to prevent soft rot, brown spot and so on.
