Method for prolonging harvest life of sugarcane by repeatedly replanting main stems of healthy original sugarcane seedlings

Abstract

The invention discloses a method for prolonging the harvest life of sugarcane by repeatedly replanting main stems of healthy sugarcane seedlings, the method comprises the following steps of: transplanting the healthy original sugarcane seedlings cultured by stem tip detoxification into a perennial root sugarcane field harvested in December or a sugarcane field newly planted in February next year for replanting after the seedlings are subjected to false planting and hardening, and when 90% of the healthy original sugarcane seedlings are tillered, cutting and transplanting the main stems to a perennial root sugarcane field harvested in January to February or a sugarcane field newly planted in March for replanting, and when 100% of the first cutting stems tillers, cutting and transplanting the main stems grown from the cutting stems to a perennial root sugarcane field harvested in March to April or a sugarcane field newly planted in April to May for replanting. By using the method, not only can the sugarcane seeds be saved, the cost of the sugarcane seeds used for replanting of the healthy sugarcane seedlings be reduced, the production period be shortened, but also the problem that the sugarcane are not replanted properly on a sugarcane field because the new planting period and harvesting period of the sugarcane are prolonged can be solved, and the harvest life of the sugarcane isprolonged.

Description

technical field [0001] The invention relates to the technical field of plant breeding and planting, in particular to a method for repeated replanting of main stems of healthy sugarcane seedlings and prolonging the harvesting period of sugarcane. Background technique [0002] Sucrose is the main body of sugar consumption in my country, accounting for more than 90% of sugar consumption. Guangxi and Yunnan are the largest sugar cane production bases in my country. The planting area and output both account for more than 80% of the national sugar cane area and output. The sugar industry is also an important pillar industry in the two provinces (regions) and an important channel for farmers' income. In recent years, due to various factors such as poor production conditions, lagging research and development of improved varieties, single varieties, slow promotion of improved varieties, rapid increase in labor costs, unreasonable breeding and planting management, and domestic and for...

AI Technical Summary

Problems solved by technology

my country's newly planted sugarcane planting and harvest overlap time is relatively long, affected by labor and harvesting time (sugarcane fields that need to be replanted must wait until harvesting is completed, and the harvesting time span is long), every year from January to May There are new sugarcane plantings in between, and due to the influence of weather, mechanical planting, sugarcane quality and other aspects, the newly planted sugarcane often exists without ridges and seedlings, which seriously affects the yield of new planted sugarcane

If the replanting with conventional stems takes too long to emerge, the growth lag will cause the replanted seedlings to be shaded, affecting the uniformity of sugarcane, and even the seedlings will die after emergence

In the past, the original seedlings of healthy sugarcane seedlings cultivated through stem tip detoxification tissue cost a lot (1 yuan / plant), and they were only used for transplanting and breeding sugarcane in the field. If healthy sugarcane seedlings are used to supplement the sugarcane , it is necessary to cultivate healthy sugarcane seedlings in stages, and the cultivation cost is higher
