Dwarf efficient close-planting cultivation method for apples

Abstract

A dwarf efficient close-planting cultivation method for apples comprises the following steps: cultivating dwarf Malus baccata nursery stocks, directly grafting target apples to the nursery stocks to obtain dwarf apple nursery stocks, performing high-density field planting on the dwarf apple nursery stocks, forming an efficient close-planting orchard consisting of close-planted apple trees, and the like. According to the method, dwarf interstocks in the prior art are removed, and technical measures such as root control on root systems of the close-planted apple trees, trunk control on trunks, branch control on branches and chemical control on growth are taken in the cultivation process, so that the production cycle is greatly shortened, and the method is quick in fruiting, low in investment, quick in effect and high in economic benefit. The dwarf efficient close-planting cultivation method for apples is simple to operate, easy to implement and low in labor intensity, is particularly suitable for the current situation that the majority of rural areas in China are extremely lack of adult labor force, is deeply welcomed and praised by the masses, can be used for a fixed orchard to achieve good economic benefits, can also be used for a mobile fruit tree base, can be independently sold for mobile fruit trees. can be moved to urban square communities for picking and the like, and is wide in application range.

Description

technical field [0001] The invention relates to a method for cultivating fruit trees, in particular to a method for dwarfing and high-efficiency dense planting of apples, which belongs to the technical field of fruit tree cultivation. Background technique [0002] Most of the existing apple dwarf cultivation methods are to first cultivate the base stock seedlings, then graft the dwarf intermediate stock on the base stock, and then graft the target variety for cultivation after the dwarf intermediate stock seedlings have grown. There are also dwarf stock varieties imported from abroad for the purpose of direct grafting, but they cannot adapt to the natural conditions of the vast area of ​​my country, especially the colder areas in the north. The seedlings used in this cultivation method usually take about 2-3 years or even longer to complete. The seedling-raising period is long, the operation is complicated, the requirements for seedling-raising technology and seedling-raisin...

AI Technical Summary

Problems solved by technology

There are also varieties imported from abroad for the purpose of direct grafting on dwarf stock, but they cannot adapt to the natural conditions of my country's vast territory, especially in the colder northern regions.

The seedlings used in this cultivation method usually take about 2-3 years or even longer to complete. The seedling raising period is long, the operation is complicated, the requirements for seedling raising technology and seedling raising environment are high, the production management cycle is long, and the cost is high.

[0003] In addition, although the existing dwarf and dense planting cultivation methods of fruit trees have the advantages of early fruiting, high yield, early maturity, and good quality, the planting density is generally 3-4×1.5-2 meters, and the planting density is 110-120 meters per mu. Plants, cultivated for 3-4 years to see fruit, 5-6 years for high yield, but there are still problems such as long production cycle, difficult field management, labor and time-consuming, high cost, large land occupation, low short-term yield, insignificant benefit, and low yield. To adapt to the current situation of the obvious shortage of rural labor force in my country
