Summer black grape single-trunk dual-main-branch shaping and two-bud trimming cultivation method

Abstract

The invention relates to a summer black grape single-trunk dual-main-branch shaping and two-bud trimming cultivation method, which specifically comprises the steps that the top is removed when a field planted seedling sprouts and grows to certain height; after the top is removed, two deputy tips which come out from a tip end part are respectively and fixedly bound on iron wires on the surface of a shed frame along the row direction, the two deputy tips reversely grow along the iron wires, the grown parts are fixedly bound while the two deputy tips grow, the two deputy tips become the two main branches of a grapevine and so a single-trunk dual-main-branch tree shape is formed. During shaping and trimming in winter, a fruiting mother branch is cut back by reserving two full buds at a base. The summer black grape single-trunk dual-main-branch shaping and two-bud trimming cultivation method provided by the invention has the advantages that the method is standard and simple, the skeleton is clear, the operation is easy to conduct, the fruiting mother branch is not required to be bound after trimming in winter, the labor is saved, the demands on the iron wires are small and the cost is low.

Description

technical field [0001] The invention relates to an agricultural planting method, in particular to a single-trunk double-main-branch shaping and two-bud pruning cultivation method for summer black grapes. Background technique [0002] Xiahei grape, a European and American hybrid, also known as Xiahei Seedless and Oriental Black Pearl, was obtained by crossing in 1968 at the Fruit Tree Experimental Field in Yamanashi Prefecture, Japan. Its parents are Kyoho and Bu Si, and it was registered in August 1997. In February 2000, my country introduced the virus-free seedlings of this variety from the Uehara Grape Research Institute in Yamanashi Prefecture, Japan. This variety is sweet and refreshing, with a strong strawberry aroma. It begins to mature in mid-July in Jiangsu, and can be kept on the tree until September. It does not crack, shatter, or aftertaste. It is a high-quality early-maturing fresh food variety suitable for large-scale development. . Natural growth, small fruit...

Problems solved by technology

[0003] At present, ordinary flat sheds or V-shaped and T-shaped frame cultivation models are mostly used in production. The tree skeleton of ordinary flat shed cultivation models is not clear, and the arrangement is relatively complicated, which is likely to cause messy branches and canopy closures, which affect the progress of photosynthesis and are prone to occurrence Diseases and insect pests, which in turn affect fruit quality; and the management is complicated, requiring overhead operations, which is time-consuming and labor-intensive

Due to the low height of the V-shaped and T-shaped frames, it is necessary to bow the head and bend over to work, the labor intensity is high, and the ventilation and light transmission are poor, and the pests and diseases are serious. In addition, the ordinary flat shed cultivation mode requires a lot of iron wires and the cost is high.
