Embodiment

[0022] The invention provides a high-density, extremely dwarf, early and high-yield cultivation method for sweet cherry arbor stock, comprising the following steps:

[0023] Step 1. Plant 333 trees per acre, with a plant spacing of 1m and a row spacing of 2m. They will be cut short from the end of June to the beginning of July of the year of planting to promote branching;

[0024] Step 2. Select a strong branch and leave 40cm, and leave other branches 20cm short to increase branches. After autumn, each tree will reach 8-15 branches with a length of 0.5m-1.5m, and the number of branches per mu will reach more than 4000, that is Complete plastic surgery;

[0025] Step 3: After the autumnal equinox, the whole garden is sprayed with 150 times paclobutrazol once to promote early stop and long-term prevention of winter freezing damage;

[0026] Step 4: In the spring of the second year, the method of multi-channel ring cutting is used to promote the germination of leaf clusters and ...

Abstract

The invention discloses an early high-yield sweet cherry cultivation method achieving high-density and highly-dwarfed vigorous stocks. The method comprises the steps that field planting is conducted according to the specification of 333 trees per mu in the mode that the plant spacing is 1 m, and the line spacing is 2 m, cutting back is conducted again from the end of June to the beginning of July in the same year of field planting, and branch emerging is promoted; a strong branch is selected, a 40-cm body of the strong branch is retained, 20-cm bodies of other branches are retained, cutting back is conducted to increase the branches, each tree grows out 8-15 branches with the length ranging from 0.5 m to 1.5 m after autumn, the branch quantity per mu reaches 4,000 or above, and then shaping is completed; 150 times of paclobutrazol is sprayed to a whole garden once after autumn equinox, early growth stopping is promoted, and winter freezing injuries are prevented; in spring of the second year, germination of leafage branches is promoted to form flower buds by adopting a multiple girdling method, branch pulling is not needed, the method is simple and easy to operate, and shaping can be completed in the same year of planting.

Description

technical field [0001] The invention relates to the technical field of sweet cherry high-yield cultivation, in particular to a high-density, extremely dwarf, early-high-yield cultivation method for sweet cherry arbor stock. Background technique [0002] Dalian area is an important sweet cherry production area in my country, with a cultivation history of more than 100 years. The economic benefit of cultivating sweet cherries is very high. It is known as the golden planting industry and is very popular among fruit farmers. In recent years, under the strong support and guidance of the Dalian Municipal Government, the cultivation area has increased rapidly, and the industrial scale has continued to expand. The cultivation area of ​​sweet cherry in Dalian has grown from less than 2000hm in 2001 2 Increased to 23326hm in 2010 2 . With the development of the rural economy, the production of sweet cherry in the greenhouse is 1 to 1 month earlier than that in the open field, and t...
