Outdoor transplanting and temporary planting method of stock seedlings of healthy sugarcane seedlings

Abstract

The invention relates to an outdoor transplanting and temporary planting method of stock seedlings of healthy sugarcane seedlings, comprising the following processes: outdoor land preparation and bed preparation; transplantation matrix preparation; sparse planting and transplanting of the stock seedlings; short-term heat preservation and moisture preservation; management of water, fertilizers andpesticides; and outplanting. In the invention, the production technology system of the biochemical virus removal of healthy sugarcane seedlings is established, the technical problems of virus removaland rapid propagation of sugarcane axillary buds are effectively solved; the seedling-growing cost is low; the seedling-growing time is short; the seedling-growing survival rate is high; the obtainedbiochemical virus-free healthy sugarcane seedlings have the characteristics of strong tillering rate, high stem forming rate, rapid growth speed, high ratooning rate and the like; the yield per unit area is improved by more than 30%; the sucrose content is improved by 0.5-1.0%; and the using amount of seedlings is saved by more than 60%. The outdoor transplanting and temporary planting method of the invention has great significance for solving the problems of serious degeneration of the sugarcane varieties and low breeding speed of the certified seedlings, plays an active role of promoting the popularization and application of healthy sugarcane seedlings and has important economic and social benefits.

Description

technical field [0001] The invention belongs to the field of open-air transplanting and artificial planting of sugarcane, and relates to a method for open-air transplanting and artificial planting of original healthy seedlings of sugarcane, in particular to a method for transplanting the original healthy seedlings of sugarcane to strengthen seedlings and artificial planting. Background technique [0002] Sugarcane (Saccharum officinarum L.) is the most important sugar crop and energy crop in the world, and sugarcane sugar accounts for about 94% of my country's total sugar production. Sugarcane is an important economic crop in tropical and subtropical regions of my country, an important source of county-level local finance in these regions, and an important economic source for farmers to increase their income. In recent years, sugarcane has been studied and utilized as an important energy crop. [0003] my country's sugarcane is mainly distributed in Guangxi, Yunnan, Guangdo...

AI Technical Summary

Problems solved by technology

[0005] Sugarcane mosaic disease and ratoon dwarf disease are diseases that are difficult to eliminate by general physical and chemical methods in production. After sugarcane is infected, it often leads to dwarfing of sugarcane plants, shortening of internodes, and decrease of sugar content, resulting in reduced sugarcane yield and quality.
