Greenhouse grape branch and tendril refreshing method

Abstract

The invention discloses a greenhouse grape branch and tendril refreshing method. After a grape plant is planted, a new tip is selected to be cultured to be a fruit bearing parent branch in the next year, after grape picking in the second year, the parent branch is subjected to layering processing to one side and is cultured to be a fruit bearing parent branch in the next year, after grape picking in the third year, the plant which is planted in the first year is partially cut off and planed off, the fruit-bearing parent branch is pressed into the position during planting, and layering is carried out on the two sides in turn every year afterwards. By the processing, grape plants are all biennial plants and annual plants, orderliness is achieved, strong growth is achieved, plant aging is avoided, Kyoho and other shortcomings that grape variety branches and tendrils cannot form good flower buds in a greenhouse are overcome, the quality and the amount of borne fruit can be guaranteed, production in successive years is achieved, and economic benefit is improved.

Description

technical field [0001] The invention relates to a crop propagation method, in particular to a method for renewing grape vines. Background technique [0002] Grapes are planted once for many years, and they need to bear fruit for many years after planting. With the extension of planting time, grape plants will have the disadvantages of reduced yield and quality, and the plants will age quickly. If the old plants are cut off and replanted, it will take at least one year to slow down the seedlings During the period, the grape yield is affected and economic benefits are reduced; for some varieties such as Kyoho, the branches and vines grown in the greenhouse cannot form good flower buds, which will affect the grape yield, quality and benefit of the coming year. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a greenhouse grape vine renewal method that keeps the plants 1-2 years old, prevents the plants from senescenc...
