Planting method capable of effectively promoting sugarcane tillering

Abstract

Provided is a planting method capable of effectively promoting sugarcane tillering. The method comprises the steps of 1, selecting healthy sugarcane seed stems, and cutting the sugarcane seed stems into chunks for standby application; 2, preparing land, opening planting ditches with row spacing of 110-120 cm, and flattening ditch bottoms and crushing and loosening soil, wherein tilling depths reach 30-50 cm, ditch depths are 25-30 cm, and widths of the ditch bottoms are 20-25 cm; 3, sowing seeds, and immediately covering the seed stems with the crushed soil, wherein buds face the two sides; 4,conducting rational close planting, wherein the planting density of big-stem-variety sugarcanes is 52500-60000 buds/hm<2>, and the planting density of middle and small-stem-variety sugarcanes is 60000-67500 buds/hm<2>; 5, applying urea as a base fertilizer 60-75 kg/hm<2>, a calcium magnesium phosphate fertilizer or calcium superphosphate 450-600 kg/hm<2> and potassium chloride 150-225 kg/hm<2> ora compound fertilizer 450-600 kg/hm<2>; 6, applying a sugarcane tillering promoting fertilizer 500-900 h/mu(a Chinese area unit and equal to 666.67 m<2>), wherein the sugarcane tillering promoting fertilizer is mixed with 2 kg of fine soil evenly before being applied and then is spread in rows evenly. According to the planting method capable of effectively promoting sugarcane tillering, tilleringand early germination can be promoted simultaneously, thus tillering parts grow and develop in sync with main seedlings, and the tillering parts and the main seedlings have no big difference at an elongation stage.

Description

technical field [0001] The invention belongs to the technical field of sugarcane planting, and in particular relates to a planting method capable of effectively promoting sugarcane tillering. Background technique [0002] Sugarcane (Saccharum spp.) is the most important sugar crop in my country. Cane sugar accounts for more than 90% of the country's total sugar output, while Guangxi's sugarcane sugar output accounts for more than 65% of the country's total output. It can be seen that the stable supply of sucrose in Guangxi is of great importance to my country. The sugar market has a pivotal position. Perennial cane cultivation is the main planting method for sugarcane production in Guangxi. The cultivated area accounts for 50-60% of the total sugarcane planting area. The lifespan of perennial roots in Guangxi is generally 2-3 years, and the production of perennials has dropped significantly by the third year. Compared with some foreign countries, the proportion of old sugarc...
