What are the methods for planting and managing persimmon trees?
How do you plant and manage persimmon trees? Please give an introduction. The methods for planting and managing persimmon trees can refer to the following methods: 1. Planting persimmon trees. 1. Choose the site and build the persimmon orchard. Choose a leeward, shady site with deep soil, fertile and loose soil, and a low groundwater table. 2. Dig holes and apply base fertilizer. Follow the mountain contour to cut horizontal terraces, and build them into mountain orchards with a front ridge and back ditch, reverse-sloping terrace surfaces, or a "fish-scale pit" style. Plant at a row spacing of 6 x 5.5 m, with 20 trees or 50 trees (close planting) per mu. The hole surface width, bottom width, and depth of the planting hole should reach 1 m, 0.8 m, and 0.6 m respectively. First allow weathering, then backfill the planting hole with weeds and topsoil to 80% full, and at the same time backfill a corresponding amount of organic fertilizer as base fertilizer, with the hole position 20 cm above the terrace surface. When planting, spread 1-1.5 kg of calcium magnesium phosphate fertilizer in each hole to improve planting quality and growth.

The methods for planting and managing persimmon trees can refer to the following methods:
I. Planting persimmon trees.
1. Choose the site and build the persimmon orchard. Choose a leeward, shady site with deep soil, fertile and loose soil, and a low groundwater table.
2. Dig holes and apply base fertilizer. Follow the mountain contour to cut horizontal terraces, and build them into mountain orchards with a front ridge and back ditch, reverse-sloping terrace surfaces, or a "fish-scale pit" style. Plant at a row spacing of 6 x 5.5 m, with 20 trees or 50 trees (close planting) per mu. The hole surface width, bottom width, and depth of the planting hole should reach 1 m, 0.8 m, and 0.6 m respectively.

When planting, spread 1-1.5 kg of calcium magnesium phosphate fertilizer in each hole to improve planting quality and growth.
3. The most suitable period for planting persimmon trees is after leaf fall in autumn and before bud break in spring, that is, before mid-February, generally no later than the Rain Water solar term.
II. Management of the persimmon orchard.
1. Increase fertilizer and improve the soil. Persimmon trees are deep-rooted tree species, so the planting holes should be expanded to improve the soil and more fertilizer should be applied for the trees to be vigorous and strong. For bearing persimmon trees, the holes should be expanded to improve the soil in winter, with holes 1-1.5 m long, 0.4 m wide, and 0.4-0.5 m deep. When backfilling topsoil, apply 100-150 kg of farmyard manure per tree, or 50 kg of dried pig or cattle manure, or 100-150 kg of mushroom soil, or 1-1.5 kg of calcium magnesium phosphate fertilizer, etc., mix evenly with topsoil and fill into the lower layer, and level the hole surface with orchard topsoil. Deep plowing to improve the soil can also be used, that is, organic fertilizer is spread at the drip line of the canopy, and then deep plowed 20 cm at the fibrous root zone. For high-yield persimmon trees, apply sufficient N 6.5 kg, P2O5 2.5 kg, and K2O 0.6 kg per mu.
2. Prune branches. For mature bearing trees with tall canopies or crossing and shading branches, moderate renewal pruning should be carried out after leaf fall in winter, mainly using heading cuts, combining thinning and renewal, cutting off dense branches, crossing branches, water sprouts, and diseased or dead branches, so as to promote reasonable branch distribution and prune into a reasonable tree form.
3. Carry out winter orchard cleaning. Winter pruning should thoroughly remove diseased fruit, diseased calyxes, dead branches, and fallen leaves, and eliminate overwintering sources of diseases and pests. For persimmon trees seriously damaged by scale insects, from leaf fall in winter to before germination in spring, spray 95% mineral oil emulsion (jiejiamanling) at 150 times or 5 degrees Baume lime sulfur.
