A kind of persimmon hedge shape shaping method

Abstract

The invention discloses a hedge-shaped shaping and pruning method for sweet persimmons. The main technical scheme is to build a high-density garden with 222 plants per mu; 0.60m, the central trunk height is 3.0m, and the crown height is 3.5-4.0m; the uniaxial branch group is cultivated, and long branches are pruned; the leaf area index is 4.5, the crown coverage is 50%-65%, and 1.5-1. The 1.8m mechanical operation lane, all plants form a continuous tree wall through the vertical frame. The invention facilitates the direct entry of orchard machinery into the orchard, saves labor costs, early formation, early yield, simple tree structure, convenient pruning, and excellent fruit quality.

Description

technical field [0001] The invention relates to the field of fruit tree shaping and pruning, in particular to a new tree shape and its supporting pruning technology suitable for mechanized operation of sweet persimmon gardens, high early yield, excellent fruit quality and easy operation. Background technique [0002] China is one of the main producers of persimmons, and its output and area both rank first in the world. It is also an important origin of astringent persimmons and sweet persimmons. Sweet persimmon (D. kakai L.f.) does not need to be artificially removed after harvesting, its fruit will naturally remove its astringency when it matures on the tree, it is peeled and eaten crisply like apples and pears, it is convenient to eat, has high nutritional value, and the crispness time is 2-3 times longer than that of astringent persimmon , is one of the main fruits consumed in Japan, China, South Korea, Hong Kong, Macao and Southeast Asian countries. The development of s...

Problems solved by technology

[0003] In the production process of astringent persimmon and sweet persimmon in my country, the main tree shape is evacuated layered shape, natural round head shape, tall tree body, high crown coverage, tree shape with central trunk, and main branches are distributed in layers on the central trunk. Many; the main branch is equipped with side branches, on which fruiting branch groups grow, and the tree structure is complex, which leads to canopy closure in the orchard during the full fruit period, poor ventilation and light transmission, poor fruit quality and complicated operations during pruning, technical requirements high, difficult to grasp

[0004] At the same time, the future sweet persimmon production will face a series of unfavorable factors

The cost of materials is increasing, the price of chemical fertilizers, agricultural film, and pesticides is increasing, especially the labor cost is also increasing. The rate of price increase is between 100% and 200%. Farmers are not willing to invest too much labor It has become very urgent to mechanize as many orchards as possible and reduce labor input. However, in the production process of sweet persimmons, the traditional evacuated layered shape and natural round head shape are adopted. Although the new orchard adopts a relatively simple heart shape, the flourishing In the orchard during the fruiting period, there are still branch transfers between plants and rows, the group structure is closed, and the canopy coverage rate is as high as 95%. As a result, self-propelled fog machines, rotary cultivators, and transport machinery cannot directly enter the orchard, hindering the orchard. increase in mechanization
