The method of repeated replanting of main stems of healthy sugarcane seedlings and original seedlings to prolong the harvesting period of sugarcane

Abstract

The invention discloses a method for repeated replanting of main stems of healthy sugarcane seedlings and original seedlings to prolong the harvesting life of sugarcane. The method is to transplant the healthy sugarcane seedlings cultivated from stem tip detoxification to December after artificial planting and hardening Replant the harvested perennial sugarcane field or the newly planted sugarcane field in February of the following year. When 90% of the healthy sugarcane seedlings have tillered, cut off the main stem cuttings and transplant them to the perennial sugarcane harvested in January-February When the first cutting stems 100% tillering occurs, cut off the main stem cuttings and transplant them to the perennial sugarcane fields harvested in March or April. The newly planted sugarcane fields are replanted in April-May. Using the method of the present invention can not only save sugarcane seeds, reduce the cost of sugarcane seedlings for replanting healthy sugarcane seedlings, shorten the production cycle, but also solve the problem that there is no suitable sugarcane in the sugarcane field due to the prolongation of the new planting period and harvest period of sugarcane. The problem of replanting prolongs the harvest period of sugar cane.

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
