Problems solved by technology

Since the number of sugarcane tillers varies with different varieties, for sugarcane varieties with low tillering ability, if the effective stem yield is increased by increasing the seeding amount and narrowing the row spacing, it is not in line with the economic principle, and it will affect the population structural quality

Abstract

The invention relates to a method for early tillering of sugarcane. The method comprises the following steps: using a paclobutrazol aqueous solution with the concentration of 5-500mg / L to soak seed stems of sugarcane for 8-48 hours, and then planting in the field according to a conventional method. The method has the advantages that in the +2 to +4 leaf stage of the seedling age of the main seedlings of the sugarcane, new seedlings begin to come up, and the tillering time is earlier than the contrast tillering occurrence time for more than three-sheet leaf age. The sugarcane tillering rate is increased by 1-3 times compared with the contrast tillering rate, therefore, the seeding quantity per unit area is reduced, and the productive tillers are added.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a method for early sugarcane tillering. Background technique [0002] Sugarcane cultivars belong to the grass family and have tillering habits. Tillering is a very important growth link in the life of sugarcane, which is of great significance to the growth and yield of sugarcane. Sugarcane is an allopolyploid or aneuploid with a very complex genetic background, and its main economic traits are quantitative traits controlled by minor polygenes, which are highly affected by environmental factors, and the heritability of tiller number is often low; At the same time, the growth cycle of sugarcane is almost the longest among grasses, and environmental factors such as light, irrigation, fertilizer, and temperature all have a great influence on the formation of effective stems by tillers. [0003] The number of effective stems is one of the important factors constituting the ...
