Key points of Management of planting Loquat Adult trees

(1) rational fertilization and (1) promoting flower fertilizer. It was applied before budding in September to promote flowering well. Mainly slow-acting organic fertilizer, oil dry + human feces + compound fertilizer. 2. Fat young fruit. After thinning fruit from February to March, the young fruit will grow slightly in spring. Application of rapidly available nitrogen, phosphorus and potassium compound fertilizer + human feces and urine. 3. Strong fruit and fat. From April to May, the fruit expanded rapidly. Apply rapidly available phosphorus and potassium fertilizer, phosphate fertilizer + potash fertilizer + human feces and urine. 4. Fruit-picking fertilizer. After fruit harvest from May to June, it was applied as base fertilizer to promote summer shoot and flower bud differentiation. Apply quick-acting fertilizer and slow-acting fertilizer, urea + phosphate fertilizer + oil withered + compost. 5. Extra-root topdressing. Spray the foliar surface with 0.3% compound fertilizer or urea solution many times.

Second, plastic pruning 1. Plastic surgery uses the trunk layered type, which can be pruned all the year round, with emphasis on summer pruning to stimulate summer shoot germination. It will be finished within 10 days after fruit picking. 2. In addition to summer pruning, one-time pruning should not be too much, and declining trees should pay more attention to pruning. Keep strong fruiting mother branches when pruning; cut short and weak fruiting mother branches; cut off erect big branches, long branches, disease and insect branches, withered branches, and remove dense branches, overlapping branches and cross branches. Second, to promote flowers in January and July. Root cutting, water control, proper drought; pulling flat branches, twisting slightly, ring cutting, ring peeling. In February, early July and early August, when 15% paclobutrazol was sprayed 1000 times or PBO hormone 350x and flowering 2 times 3, 0.25% potassium dihydrogen phosphate + 0.2% urea solution was sprayed. 4. Spray 0.001% "920" during the flowering period. In May, the flowers were thinned in the first ten days of November, and there were only 1 Mel and 2 flower spikes on one fruiting mother branch. After the cold wave in June and March, there were 5 fruits per panicle of medium fruit type varieties and 3 fruit per ear of large fruit type varieties. 7. Three steps of fruit thinning: one shake, 80% discount, and three thinning. Defrost harmful fruit, disease and insect fruit, deformed fruit, too small fruit, too dense fruit. Fourth, pest control 1. Brush the tree trunk with lime paste in winter and burn the disease and insect branches in the garden. 2. Turn the soil in winter and kill some overwintering pests. 3. In the period of new shoot, flowering and fruiting, topurazine + enemy kill + fenitrothion can control leaf spot, anthracnose + yellow caterpillar + pear heart borer, peach borer and so on. Fifth, drought resistance and dehumidification 1. Because of its fear of dry and wet, it should be covered, irrigated and sprayed during winter and spring drought to prevent sunburn to avoid dried flowers and shrunken fruits. 2. Deep trenches are opened for drainage in the rainy season (which begins in June). 6. Anti-cracking and anti-freezing 1. During the color conversion period (turquoise → light green), 0.14% vinyl was sprayed to prevent cracking once every 15 days, and ripening 7 days ahead of schedule. 2. Before the severe cold comes, the flower spikes around the crown cover paper bags from top to bottom, from the inside to the outside, and remove the paper bags after heating up. From December to January of the following year, spray 0.2% urea + 0.3% potassium dihydrogen phosphate.
