Cultivation method of black-peel chewing cane healthy tissue-cultured cup seedlings planted in early spring for coming into market in winter

Abstract

The invention provides a cultivation method of black-peel chewing cane healthy tissue-cultured cup seedlings planted in early spring for coming into the market in winter. The cultivation method comprises the following steps of: planting the black-peel chewing cane healthy tissue-cultured cup seedlings according to a certain plant row space with a density of 900-1,100 plants per mu and promoting tillers to come up and grow through water manures and cultivation measure management; removing main seedlings, thinning out seedlings and final singling seedlings from a peak tillering period of the tissue-cultured cup seedlings to an initial jointing stage, wherein each tissue-cultured seedling reserves 3-4 tillering seedlings having basically consistent growth; and using the ripened stems of the tillering seedlings as commercial chewing canes. The cultivation method has the advantages that the tillering seedlings of the planted black-peel chewing cane healthy tissue-cultured cup seedlings grow into the commercial chewing canes, and the aspects of plant heights, internode lengths, stem diameters, field brix, and the like of the commercial chewing canes are superior to that of conventional cultivated plants; the commercial chewing cane rate reaches more than 95 percent; and the output of the commercial chewing canes per unit area is increased by more than 20 percent. Moreover, the chewing canes are planted in early spring and can come into the market in winter, thereby greatly shortening the planting time.

Description

technical field [0001] The invention relates to a method for cultivating fruit cane, in particular to a high-yield cultivation method for healthy tissue-cultured cup seedlings of black-skinned fruit cane planted in early spring and listed in winter. Background technique [0002] The name of black-skinned fruit cane is Badila, and it is also called black-skinned cane because of its purple-black stem color. Black-skinned fruit cane is a prominent variety of fruit cane in my country, with a planting history of more than 50 years. It is the main cultivated variety of fruit cane in southern sugarcane regions such as Guangxi and Guangdong. Among them, the planting area of ​​black-skinned fruit cane in Guangxi accounts for more than 90% of the total area of ​​fruit cane. Due to long-term planting and self-reserved species, the species degradation is serious. At present, the use of tissue culture technology to produce virus-free healthy seedlings is an effective technical measure t...

AI Technical Summary

Problems solved by technology

At present, the production conditions in my country's sugarcane areas are complex, and the virus-free healthy seedlings have not been well isolated during the breeding process, and the probability of re-infection is high, especially for mosaic disease. It will greatly reduce the detoxification synergistic effect of detoxified healthy seedlings
