Embodiment 1

[0024] A planting method capable of effectively promoting tillering of sugarcane, comprising the steps of:

[0025] (1) choose healthy sugarcane seed stem, cut double bud section, stand-by;

[0026] (2) Soil preparation, plowing depth reaches more than 30-40cm, open planting ditch, open planting ditch according to row spacing 110-120cm, ditch depth 25-30cm, ditch bottom width 20-25cm, ditch bottom flat, finely crushed soil; It is required that the specific degree of deep plowing must be adapted to local conditions. The plowing depth should be 30-40cm, preferably more than 50cm if conditions permit, and the plowing layer should be deep, loose, broken and flat.

[0027] (3) planting, the buds are to both sides, and then cover the stem with crushed soil;

[0028] (4) Reasonable dense planting, 45000-67500 buds per hectare;

[0029] (5) A large amount of fertilizer: 60-75kg of urea per hectare of base fertilizer (3-5kg per mu), 450-600kg of calcium magnesium phosphate fertilizer...

Abstract

A planting method capable of effectively promoting tillering of sugarcane, comprising the steps of: (1) selecting healthy sugarcane seed stems, cutting them into sections, and setting aside; ‑120cm to open the planting ditch, the ditch depth is 25‑30cm, the ditch bottom width is 20‑25cm, the ditch bottom is flat, and the soil is finely crushed; (3) planting, buds to both sides, and then cover the stem with crushed soil; (4) reasonable Close planting, the planting density of sugarcane with large stem varieties is 52500‑60000 buds / hm 2 , the planting density of medium and small stem varieties of sugarcane is 60000‑67500 buds / hm 2 ; (5) urea 60-75kg / hm as base fertilizer 2 , calcium magnesium phosphate fertilizer or superphosphate 450‑600kg / hm 2 and potassium chloride 150‑225kg / hm 2 Or compound fertilizer 450‑600kg / hm 2 (6) Apply sugarcane tillering-promoting fertilizer 500-900g / mu, mix it with 2kg of fine soil before application, and evenly scatter in the row then. The planting method of the invention can simultaneously promote the early onset of tillers, so that the tillers and main seedlings grow and develop synchronously, and there is little difference between the two at the jointing 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 root cane cultivation is the main planting method of 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. By the third year, the perennial cane production has dropped significantly. Compared with some foreign countries, the proportion of sugarcan...
