A variety of good seedless persimmon tube grasp three

The non-nuclei Diospyros deciduous fruit trees have been planted in Zhejiang for thousands of years. Non-nucleate persimmon has strong adaptability, can be planted except for saline-alkali land, and is especially suitable for planting in the headland of Tiantou 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. Another planting method is to plant the annual rootstock seedlings directly into the planting hole, and then wait until the rootstock seedlings are fully lived before grafting. Although slower with this method, the survival rate is high. 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 to make them the result of the branches. As a result, when the branches are extended for many years, the cut trimming can be appropriately shortened to form more fruiting branches. Fertilization is mainly applied to basal fertilizer to enhance top dressing. Basal fertilizer is applied before and after harvesting or before sprouting. Mainly delayed-effect fertilizers (such as bar fertilizer, cake fertilizer, etc.) are used to dig pits deeper than 50 cm around the trees. Fertilizers are generally based on quick-acting fertilizers (such as feces and urine), and N, P, and K must be mixed, depending on the amount of tree-like ingredients. 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 had a polygonal leaf shape. The latter had a round leaf shape. When the leaf was severe, the leaves fell off, causing a large number of fruit failures when it was damaged. Control methods: (1) Remove pathogens after defoliation and before germination, remove dead branches, and remove defoliant incineration. (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 mainly causes damage to the shoots, which generally occurs in early June in July-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. The main pests of the persimmon tree are the persimmon cotton beetles, the turtle wax beetles, the kaki insects, and the blood spot leaflets. Control methods: use 20% dimethoate 1000 times solution, 50% marathon 1000 times solution, 800 times dipterex mixed with dimethoate, 50% dichlorvos 1500 times solution, such as Pyrethroid and other pesticides have good control effect.
