Persimmon tree cultivation
Choose a place to build a persimmon orchard. It is advisable to choose a leeward shaded land with deep soil, fertile and loose soil, and low groundwater level.
Dig holes and apply base fertilizer to adapt to the mountain, and build a horizontal terrace, which should be built into a front ridge and a ditch, an anti-skewed platform or a "fish scale pit" type mountain garden. Planted in rows with a spacing of 6×5.5 meters, 20 or 50 plants (close planting) per mu. The hole surface width, bottom width and depth of the planting hole should be 1m, 0.8m and 0.6m respectively. After weathering, the planting hole is backfilled with weeds and topsoil at most half full, and an appropriate amount of organic fertilizer is used as base fertilizer. High table top 20 cm. Sprinkle 1.5 kg of calcium magnesium phosphate fertilizer per hole during cultivation to improve the quality and growth of planting.
Suitable time for planting The most suitable time for planting persimmon trees is after leaf fall in autumn and before budding in spring, generally not exceeding the rain solar terms.
Persimmon orchard management
The persimmon tree is a deep-rooted tree species, and the hole should be expanded to improve soil and fertilizer to grow vigorously. The persimmon trees put into production need to expand the hole and change the soil in winter, the hole length is 15 meters, the width is 0.4 meters, and the depth is 0.4 to 0.5 meters. When backfilling the topsoil, apply 50-100 kg of soil miscellaneous fertilizer or 50 kg of dried pig and cow manure or 50-100 kg of mushroom soil or 15 kg of calcium magnesium phosphate fertilizer, etc., mix it with the topsoil and fill it into the base layer. Use the garden topsoil for the cave surface It can also be filled up, and the soil can also be deepened, that is, organic fertilizer is applied to the drip line of the canopy, and then the fibrous rhizosphere is turned 20 cm deep. For high-yield persimmon trees, 6.5 kg of nitrogen fertilizer, 2.5 kg of phosphate fertilizer and 0.6 kg of potassium fertilizer should be applied per mu.
Pruning the adult trees with huge crowns or interspersed and shaded branches should be properly retracted and pruned after deciduous in winter, using short-cutting as the main method, combined with thinning, cutting off dense branches, interspersed branches, long branches and diseased dead branches , Promote the reasonable spread of branches and cut them into a reasonable tree.
There are many kinds of pests and diseases of persimmon trees in winter, and cleaning persimmon orchards in winter is an effective period for control. Persimmon angular spot disease, round spot disease, anthracnose, etc., live on fallen leaves, dead branches and other sick tissues in winter. The remaining leaves and fallen leaves on the tree should be burned together to reduce the incidence of the coming year; If pests live in the old bark and peel of the persimmon tree, and in the damaged young fruit, they should scrape off the old bark and peel, and remove the fruit hanging on the persimmon tree. The concentrated burning can eliminate the pupae and larvae of the persimmon stalk. Reduce the harm in the coming year, ensure the healthy growth of persimmon trees, and improve fruit quality. Before deciduous leaves in winter and before germination in spring, it should be sprayed with 95% motor oil emulsion (scale miteling) 150 times or Baume 5 degree lime sulfur mixture for control.
