The non-nuclei persimmon deciduous fruit tree has strong adaptability. It can be planted except for saline and alkaline land. It is particularly suitable for planting in the corner of the field and beside the village road. It is a tall tree with large leaves and shade. It can be used to beautify the environment. It is fruity and red in autumn and winter. It has a variety of uses such as fruit picking, viewing, shading, and cooling.
First, the cultivation of seedless persimmon seedless persimmon planted in the late autumn season, such as a piece of planting, planting distance should be in the row spacing of 56 meters, the most dense not more than 45 meters. The planting hole has a depth of 1 meter and a diameter of 1 meter. The planting depth is 5 centimeters below the ground plane. Planted too deep, poor growth of fruit trees, planted too shallow, it is easy to be blown down by the wind, vulnerable to low temperature damage. Another planting method is to plant the annual rootstock seedlings directly into the planting hole, and then graft them after the rootstock seedlings completely live. Although slower with this method, the survival rate is high. Because the rootstock seedlings are easy to grow and easy to survive, they will be exempted from transplanting procedures after being grafted and will not injure the grafted part.
Second, plastic, pruning and fertilizing pruning time is generally carried out after defoliation and before the next year's germination. The dry height is about 1.5 meters. In the case of natural growth without seeds, perennial persimmons often maintain the center's leadership, and the main branches are distributed hierarchically on the center's leadership, naturally forming evacuation layered shapes and the main branch naturally happy-shaped crown. Each year, short cuts are made to the trunk and main branches to form a strong skeleton. The long branches may be appropriately shortened so that they become the result of the branches. As a result, if the branches have been extended for too many years, they may be shortened by trimming the pruning section to form more fruiting branches. The canopy will look at a fan far away and look at an umbrella. Achieve more results and higher yields. Fertilization is mainly applied to basal fertilizer to enhance top dressing. The basal fertilizer is applied before and after harvesting or before sprouting. The topdressing fertilizer is generally based on quick-acting fertilizers (such as human waste). To mix N, P and K, it depends on the amount of tree-like preparation. The first time before flowering, the first Secondary application at the beginning of fruit development can prevent late physiological fruiting, increase fruit set, and increase yield.
3. Disease and Pest Control Persimmon leaf spot disease and persimmon leaf spot disease are the major diseases that damage the persimmon leaves and persimmon. The former is a diseased leaf with a polygonal shape, while the latter is a diseased leaf with a round shape. When the leaf is severe, the leaves fall off, causing a large number of persimmon trees to drop fruit when it is harmed.
Control methods:
(a) Remove the disease after defoliation and before germination, remove dead branches, and remove defoliants for burning.
(B) In the middle of June, spray a 1:5:600-fold Bordeaux mixture, ie, 1 kg of copper sulfate, 5 kg of lime, and 600 kg of water, spray once every other half month. Or spray with 400-500 times Daisen zinc solution. Persimmon anthracnose is a major hazard to the branches, and it usually occurs in early June. The incidence of fruit is from July to September. Control methods: Spray 5 times lime sulfur before germination, spray 600 times Bordeaux mixture after 6 months. Note that it is not appropriate to apply pure nitrogen fertilizer during the growth period to prevent the shoots from being green and tender.
Insect pests of persimmon trees are mainly persimmon cotton beetles, turtle wax beetles, kaki worms, and blood spot leaflets.
Control methods: use 20% dimethoate 1000 times solution, 50% marathon 1000 times solution, 800 times dipterex mix 100 dimethoate, 50% dichlorvos 1500 times solution, such as pyrethrin and other pesticides have good control effect.
