Who knows the cultivation and management of persimmon trees?

First, persimmon tree planting. 1. Choose a site to build a persimmon orchard. It is appropriate to choose the leeward direction with deep soil layer, fertile and loose soil and low groundwater level. 2. Dig a hole and apply base fertilizer. To form a horizontal terrace according to the mountain situation, it is necessary to build a front ridge and a back ditch, an anti-inclined countertop or a "fish scale pit" mountain garden. According to the row spacing of 6×5.5 meters, 20 or 50 plants (close planting) are planted per mu. The hole surface width and bottom width and depth of the planting hole should reach 1m, 0.8m and 0.6m respectively. After weathering, the planting holes should be backfilled with weeds and topsoil to 80% full. At the same time, a considerable amount of organic fertilizer should be backfilled as base fertilizer, and the height of the hole platform is 20cm. When planting, calcium magnesium phosphate fertilizer 1- 1.5 kg was applied to each hole to improve the quality and growth of planting. 3. The most suitable time for persimmon planting is after defoliation in autumn and before germination in spring, that is, before mid-February, which generally does not exceed the solar term of rain. Second, persimmon orchard management. 1. Increase fertilizer and improve soil. Persimmon is a deep-rooted tree species. It needs to expand holes, improve soil and increase fertilizer to make the tree grow vigorously. In winter, persimmon trees put into production should be enlarged to improve the soil. Hole length 1- 1.5m, hole width 0.4m and hole depth 0.4-0.5m When backfilling topsoil, plants should apply100-150kg of soil miscellaneous fertilizer, 50kg of dry pig manure and100. , and then mixed with topsoil to fill in the lower layer, the hole surface should be filled with topsoil in the garden. N6.5 kg P2O52.5 kg and K20.6 kg were applied to persimmon trees with high yield per mu. 2. Trim the branches. Adult trees with tall crowns or shaded branches put into production should be moderately retracted and pruned after defoliation in winter. Short branches should be used to prune dense branches, cross branches, clustered branches and diseased dead branches, so that the branches can be distributed reasonably and cut into reasonable tree potential. 3. Clean the garden in winter. Winter pruning should thoroughly remove diseased fruits, diseased stems, dead branches and fallen leaves, and remove the source of overwintering pests and diseases. Persimmon trees seriously damaged by scale insects should be sprayed with 95% oil emulsion (acaricide) 150 times or Pomei 5-degree stone sulfur mixture before defoliation in winter and germination in spring.
