Embodiment 1

[0020] (1) Starting and running

[0021] Select plots with fertile land, good drainage and irrigation conditions, and corn in front; deep plowing and deep loosening, fine soil preparation, deep plowing of more than 0.3m, raking and raking; furrowing according to 1-1.2m furrow surface, furrow height 0.15-0.2 m, the furrow width is 0.4-0.5m; planting furrows are made on the furrow surface at a row spacing of 0.4m, and the furrow depth is 0.1-0.15m; 3 rows are planted in each furrow.

[0022] (2) High density planting

[0023] First-level seedling field: In April, cut off about 2 / 3 of the leaves of bare-root seedlings in sand beds with a pseudostem height of 10-20 cm, and plant them in the planting ditch at a distance of 0.4 m (about 3333 plants per mu), and then cultivate the soil for 2 ~3cm, pour enough water for root fixation; adopt small arched shed transplanting technique (Tang Junhai, Tang Liqiu, Lu Zuzheng et al. Experimental report on small arched shed field transplantin...

Abstract

The invention discloses a high-density expanding propagation method of healthy sugarcane seedlings, which comprises the steps of (1) ridging and ditching, (2) high-density planting, (3) fine field management and (4) shearing and harvesting and stubble cane management. According to the method, in the processes of seed production and expanding propagation of the healthy sugarcane seedlings, a high-density expanding propagation technology is adopted for expanding propagation, so that the purposes of saving land resources, reducing reinfection rate of a pathogen and increasing the total number of buds in unit area are achieved, the intensive and fine management is realized, the expanding propagation efficiency is improved, and a positive promotion effect is played on accelerating the popularization of the healthy sugarcane seedlings.

Description

technical field [0001] The invention belongs to the technical field of sugarcane seedling propagation, in particular to a high-density propagation method for healthy sugarcane seedlings. Background technique [0002] Sugarcane is a vegetatively propagated crop. After years of continuous vegetative planting, various pathogens have repeatedly infected and accumulated in the plants, especially sugarcane perennial root dwarf disease, mosaic disease and other diseases that cannot be controlled by chemical drugs. The quality and yield of sugarcane will degenerate continuously, which will cause great losses to production and seriously threaten the safety of sugarcane planting industry. More than 30% of the varieties used in production are infected with mosaic disease, and 100% are infected with perennial dwarf disease. The use of tissue culture technology to produce detoxified healthy seedlings can realize healthy and non-toxic sugarcane production, so that the seed properties of ...
