A method for rapid breeding of sugarcane healthy seedlings by transplanting original seedlings three times

Abstract

The invention discloses a method for repeatedly transplanting and rapidly breeding healthy sugarcane seedlings for three times, which comprises the following steps of: transplanting healthy sugarcaneseedlings cultured by tissue culture into a field after false planting and hardening seedlings; and when 90% of the original healthy sugarcane seedlings are tillered, cutting off the main stems for cutting and transplanting, and cutting off the main stems grown from the cutting stems for cutting and transplanting when 100% of the first cutting stems are tilled. By using the method, the sugarcane seeds can be saved by changing one mu into three mu, the planting and management time can be staggered, and the utilization rate of machinery and labor can be greatly improved; the sugarcane seeds canbe harvested in batches, and the problems that the sugarcane seeds of a double-high sugar material sugarcane base are intensively harvested, which causes obvious transition of a slack season and a busy season and seriously lack of seeds in the later period are solved; the production period can also be shortened, the production cost is saved, and high-quality sugarcane seeds and high-yield sugarcane can be quickly harvested.

Description

technical field [0001] The invention relates to the technical field of plant breeding and planting, in particular to a method for rapid breeding of sugarcane healthy seedlings and original seedlings transplanted three times. 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, affected by various factors such as poor production conditions, lagging research and development of improved varieties, single variety, slow promotion of improved varieties, rapid increase in labor costs, and fluctuations in domestic and foreign prices, the benefits of sugarcane planting h...

Problems solved by technology

[0005] In view of the problems described above, the purpose of the present invention is to provide a method for rapid breeding of sugarcane healthy seedlings by transplanting the original seedlings 3 times, which can realize the cost reduction of more than 60% for repeated expansion of the main stem twice, not only Realize one mu into three mu, save sugarcane seeds, and can stagger the planting and management time, which greatly improves the utilization rate of machinery and labor; it can also harvest sugarcane seeds in batches, alleviating the risk of sugarcane production in the double-high sugarcane base. It can also shorten the production cycle, save production costs, and quickly harvest high-quality sugarcane seeds and high-yield sugarcane
