A kind of sugarcane seedling cultivation method

Abstract

The invention discloses a method for cultivating sugarcane seedlings. The invention belongs to the technical field of sugarcane seedling planting methods. The method comprises the following steps: drying pond mud, mashing it for use for later use; mashing and sieving the surface soil of the cultivated land to obtain fine mud for future use; mixing fine sand and fine mud to obtain sand A; putting the mashed pond mud In the bottom layer of the cultivation frame, silt A is laid on the upper surface of the pond mud to obtain a culture medium; seeds are sown on the culture medium, and then covered with silt B mixed with fine sand and fine mud; water the culture frame, cover the film, and control Control temperature and humidity until seedlings emerge, remove the film, continue to control temperature and humidity until the seedlings grow to 5-6 leaves, and carry out artificial planting of seedlings; two weeks after the artificial seedlings, start spraying nutrient solution, spray once a week until full growth When the seedlings grow to more than 30cm, they are transplanted in the field. The invention has simple operation process, saves cost, only needs a small amount of chemical fertilizer, reduces phytotoxicity, and has high survival rate and vigorous growth of seedlings.

Description

Technical field [0001] The present invention relates to the technical field of sugarcane seedling planting methods, more particularly to a sugarcane seedling cultivation method. Background [0002] Sugar cane industry is the pillar industry of Guangxi's economy, Guangxi sugarcane planting area accounts for about 65% of the total area of the country, sugar production accounts for about 70% of the total sugarcane sugar (accounting for about 65% of the total sugar in the country), Guangxi sugar occupies a pivotal position in China's sugar supply, the total amount of sugar commodities transferred out of the region every year accounts for more than 80% of the country, due to Guangxi's unique natural conditions and location advantages, guangxi has become China's largest sugar production base and sugar production center. The rapid development of the sugar industry has greatly promoted the development of Guangxi's economy, but at present, the slow renewal of sugar cane varieties in Guang...

Problems solved by technology

[0004] Conventional seedling cultivation substrates require steam autoclaving or dry heat disinfection, which requires expensive equipment and high labor costs. At the same time, conventional seedling cultivation operations are complicated, time-consuming, labor-intensive, cost-intensive, and the cultivation time is long.

At the same time, due to the insufficient fertility of the cultivation substrate, conventional planting needs to spray a large amount of fertilizer, which is not easy to control and is prone to phytotoxicity, which affects the growth of seedlings.
