Winter cultivation and management methods of persimmon

First, persimmon tree planting

1. Choose a land to build a persimmon garden. It is advisable to choose a leeward and sloping land with deep soil layers, fertile soil and low groundwater level.

2. Dig a hole in the base fertilizer. In order to meet the mountain's potential level, it should be built into a front and rear ditch, a counter-sloping countertop or a "fish scale pit" type mountain garden. According to the row spacing of 6 meters - 5.5 meters, 20 plants per acre or 50 plants (close planting) planted. The width of the hole and the width of the bottom of the planting hole should reach 1 m, 0.8 m and 0.6 m respectively. After weathering, the weeds should be backfilled to the planting hole, and the topsoil will be filled to 80%. At the same time, a considerable amount of organic fertilizer will be backfilled as the base fertilizer. High table top 20 cm. When planting, apply 1~1.5 kg of calcium magnesium phosphate fertilizer per hole to improve the quality of planting and ensure the growth demand.

3. Planting the appropriate period. The most suitable period for planting persimmon trees is after the autumn leaves and before the spring germination, that is, before mid-February, generally no more than the rainy season.

Second, persimmon tree garden management

1. Increase fertilizer and change soil. Persimmon trees are deep-rooted tree species, which should be expanded to change soil and increase fertilizer to make the tree flourish. In the winter, the persimmon tree should be expanded to change the soil. The hole length is 1 to 1.5 meters, the width is 0.4 meters, and the depth is 0.4 to 0.5 meters. When backfilling the topsoil, the plant is mixed with 100-150 kg of soil or 50 kg of pig manure or 100-150 kg of mushroom soil or 1 to 1.5 kg of calcium, magnesium and phosphate fertilizers, mixed with the topsoil and filled into the lower layer. The inner topsoil is filled in. It can also be turned deep into soil, that is, organic fertilizer is applied to the canopy drip line, and then 20 cm deep in the rhizosphere. 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.

2. Trim the branches. Adult trees with tall canopy or cross-cutting shades should be moderately retracted and pruned after winter leaves, short-cutting, shrinking and combining, cutting off dense branches, cross branches, long branches and dead branches to promote reasonable distribution of branches. , cut into a reasonable tree.

3. Winter clearing. Winter pruning should completely remove the diseased fruit, diseased pedicle, dead branches and fallen leaves, and eliminate the source of wintering pests. Persimmon trees with heavy worms should be sprayed with 95% oil emulsion (蚧螨灵) 150 times or Baume 5 degree stone sulphur mixture before winter germination to spring germination.
