Abstract

The invention relates to a sugarcane seedling culture method. The method comprises the steps of preparing sugarcane seedling culture matrix, laying the sugarcane seedling culture matrix, sowing seeds, and moving a sowing frame to a greenhouse provided with a sunshade net and peripherally covered with thin film to perform seedling management. According to the method, the matrix is rich in nutrition, the seedling culture operation is simple, the seedling culture cost is low, and the method can be popularized and used on a large scale. According to the sugarcane seedling culture method, the average germination rate of seeds reaches 98.4%, the average survival rate of temporary planting reaches 99.0%, and obtained sugarcane seedlings are robust and excellent.

Description

technical field [0001] The invention belongs to the technical field of plant sexual reproduction, and in particular relates to a method for growing sugarcane seedlings. Background technique [0002] Sugarcane is an annual or perennial tropical and subtropical herbaceous plant, which is a C4 crop. Cylindrical stem, erect, tillering, clustered, noded, with buds on nodes, solid internodes, covered with wax powder, purple, red or yellow-green, etc., clustered leaves with thick white midribs; large panicles Terminal, with silvery long hairs at the base of spikelets, oblong or oval caryopsis small. [0003] The country with the largest sugarcane planting area is Brazil, followed by India, and China ranks third. Sugarcane is the main raw material for sugar production in China. In the world's total sugar production, sucrose accounts for about 65%, while China accounts for more than 80%. Sugar is one of the essential foodstuffs for human beings, and it is also an important raw ma...
