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.
