A kind of cultivation method of controlling root and crown of big cherry

Abstract

The invention discloses a root and crown controlling cultivation method for large cherry trees, and relates to the technical field of cherry tree cultivation. The method includes the following steps that step1, according to land selection, a planting site at the plateau warm and cool region is selected, wherein the elevation ranges from 1800 m to 2400 m ; step2, seedling selection is performed; step3, root-controlling field planting is performed; step4, trunk heading is performed for the first time; step5, first layers of fruit-bearing branch groups are cultivated; step6, trunk heading is performed for the second time; step7, second layers of fruit-bearing branch groups are cultivated; step8, trunk heading is performed for the third time; step9, third layers of fruit-bearing groups are cultivated; step10, trunk heading is performed for the fourth time; step11, fourth layers of fruit-bearing branch groups are cultivated; step12, shaping is performed. The cultivation method has the advantages that the method can regulate and control root systems and enable lateral roots to be thick and short, the photosynthesis of tree crowns is sufficient, the time for cultivating the fruit-bearing branch groups is shortened by 1-2 years, planting density is high, the land area is saved, and the yield of cherries can be obviously increased.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a root-controlled and crown-controlled cultivation method for large cherry. Background technique [0002] Big cherries, also known as cherries, refer to imported cherries with thick skins produced in the United States, Canada, Chile and other American countries, not Chinese cherries with small skins. Although there are currently introduced cherries in my country, But it hasn't reached a scale yet. The prior art discloses a planting method of cherries (application publication number CN104115721A), and the technical measures adopted in the cultivation and management steps of the disclosure are: before germination in spring or after leaves fall in autumn, transplant 1-year-old grafted Finished seedlings; the ratio of the main species to the pollinated species is 3-5:1, adopt free spindle shape shaping, set the stem at about 80cm in the first year after planting, and p...

However, the cultivation time of this cultivation method is as long as 4 years. If it is counted from the 3rd or 4th year of cherry planting, it will take 7-8 years in total, so it takes too long, which is not conducive to high yield and economic income of farmers.
