Method for promoting branching of central trunk of tree-rootstock sweet cherry

Abstract

The invention relates to a method for promoting branching of a central trunk of a tree-rootstock sweet cherry. The method includes the following steps: a first step, nursery stock selection; a second step, soil preparation and repairing and a nursery stock planting technique; a third step: a branching promoting technique: 1) notching buds; 2) spraying the buds with an AB branching hormone; and a fourth step: a branch opening angle technique. The problem that because the long and thin spindle-shaped or super thin spindle-shaped trimming process is not suitable for the tree-rootstock sweet cherry, and then the branching number is few, and the branching length and the branching angle are not suitable can be solved; and many buds on the central trunk of high-quality strong seedlings are notched, and the buds are sprayed with the novel AB branching hormone, and in this way, the number of branching of the central trunk is increased, the growth vigor of the new germinated shoots is even, tree body forming can be achieved early, fruit bearing is earlier, the high yield can be achieved rapidly, and establishment of a short-trunk narrow-crown tree body structure is facilitated.

Description

technical field [0001] The invention relates to a method for planting cherries, in particular to a cultivation technique for promoting multiple shoots in the central stem of cherries, and belongs to the technical field of cherries. Background technique [0002] Dwarfing and dense planting cultivation is the development direction of fruit trees in the world, but production practice at home and abroad has proved that sweet cherries on dwarf stocks have many problems, such as many fruits, difficult artificial fruit thinning, small fruit, low selling price, and rapid tree decline. The main sweet cherry producing countries in the world and our country have so far mainly used sweet cherry seedlings with arbor anvils. The advanced cultivation and management technology adopted at present is "dense planting of arbor anvils and dwarf management", which means to adopt dense planting of arbor anvils and apply dwarf management technology.

Problems solved by technology

[0003] Research and production practice at home and abroad have proved that the slender spindle shape or superfine spindle shape is the main tree shape used in modern sweet cherry dense planting cultivation, but in actual operation, there are problems such as unsuitable fixed stem height, small number of shoots, and growth potential of lateral branches. The application effect is unsatisfactory due to problems such as strong tree crown, large crown, and late formation; how to make the planted arbor seedlings have ideal shoot height, appropriate shoot number, shoot length and shoot angle, and quickly form a tall spindle or ultra-fine spindle , early results, early high yields, and early returns are major issues that the industry needs to solve urgently

[0004] The techniques for promoting the dry branching of sweet cherry center mainly include setting the stem, cutting the buds, and smearing branching agents (such as Huazhibao, Promalin, etc.), etc. Tian Changping of Yantai Academy of Agricultural Sciences (Shandong Agricultural Science , 2013, 45(2): 75-77) The study showed that "cutting buds + coating promarin" is more beneficial to promote the growth of lateral branches with more central trunk than single bud carving and promarin coating. The structure of the body is well-proportioned and reasonable; but the application of Promarin is time-consuming and labor-intensive, and the labor efficiency is low
