Problems solved by technology

[0004] In view of the low temperature in the early stage of the existing technology, the seedling germination time is long, and the seed buds are easily eroded and necrotic by pathogens during the long germination process, and miss the golden period of great elongation in June, the effective growth period of sugarcane Short, technical issues leading to low cane yields and sugar yields

Embodiment 1

[0021] Embodiment one: sugarcane planting method

[0022] A planting method for improving sugarcane yield and sugar production rate. The planting method prepares the ground before planting, opens planting cane furrows and applies base manure, selects new planting cane without pests and diseases as seeds, and passes the selected seedlings through plant probiotics. Sow the seeds from November to January of the next year after soaking in the bacterial mixture, cover them with plastic film, and harvest after germination, tillering, growth and maturity.

[0023] In the present invention, the newly planted cane variety is one of Yuetang 79-177, Yuetang 82-882 and Yuetang 83-88.

[0024] The planting method of the present invention completes the sugarcane germination tillering stage before the end of May.

Embodiment 2

[0025] Embodiment 2: Preparation of plant probiotic mixture

[0026] In the present invention, the mixed solution of plant probiotics is to expand and cultivate the activated Bacillus subtilis, Bacillus licheniformis, Streptomyces KN37 and Trichoderma harzianum respectively, and cultivate the Bacillus subtilis culture solution, Bacillus licheniformis culture solution and Streptomyces KN37 liquid and Trichoderma harzianum culture liquid were mixed in a volume ratio of 1:0.5:1:1.5 to obtain a plant probiotic mixed liquid.

[0027] In the present invention, Bacillus subtilis and Bacillus licheniformis adopt common commercially available strains, and what Bacillus subtilis and Bacillus licheniformis purchased are bacterial agents of Jinan Jinhua Fenghui Biotechnology Co., Ltd., Streptomyces KN37 (Streptomycessp.KN37) and Harzwood Mold (Trichoderma harzianum) is the purchased strain, and the strain preservation number of Streptomycessp.

Embodiment 3

[0032] Example 3: Preparation of Plant Probiotics Mixture

[0033] In the present invention, the activated Bacillus subtilis, Bacillus licheniformis, Streptomyces KN37 and Trichoderma harzianum are respectively inoculated in the culture medium of the Erlenmeyer flask, the inoculum amount is 3-5% (V / V), and they are respectively inoculated into the fermenter after being cultivated for 12 hours. Expand the culture medium until the number of viable bacteria reaches 10 9 cfu / mL to obtain Bacillus subtilis culture fluid, Bacillus licheniformis culture fluid, Streptomyces KN37 culture fluid, and Trichoderma harzianum culture fluid.

[0034] The plant probiotic mixed solution of the present invention is obtained by mixing Bacillus subtilis nutrient solution, Bacillus licheniformis nutrient solution, Streptomyces KN37 nutrient solution, and Trichoderma harzianum nutrient solution in a volume ratio of 1:0.7:1.5:1.7, and the total concentration of live bacteria 1×10 10 ~10 12 cfu / mL....

Abstract

The invention provides a planting method for improving sugarcane unit yield and sugar yield. The planting method comprises the following steps: performing field preparation before planting, opening sugarcane planting ditches and applying a basal fertilizer, selecting new planted sugarcane without pests and diseases as seeds, selecting new planted sugarcane seeds without pests and diseases, soakingthe selected sugarcane seeds in a plant probiotic mixed solution and then performing planting from November to January of the following year, adopting plastic film mulching after planting, and performing cutting harvest after going through the germination period, tillering period, growth period and mature period. The sugarcane planting method of the invention adopts autumn and winter planting, and uses the mixed bacterial solution composed of a Bacillus subtilis culture solution, a Bacillus licheniformis culture solution, a Streptomyces sp. KN37 culture solution, and a Trichoderma harzianum culture solution to soak the sugarcane seeds, and plastic film mulching is performed after planting, so that the effective growth period is prolonged, germination and tillering are ensured, and therebythe sugarcane unit yield and sugar yield are increased.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting and relates to a sugarcane planting method, in particular to a planting method for increasing sugarcane yield and sugar production rate. Background technique [0002] Sugarcane (Saccharum spp.) is the most important sugar crop in my country, and the traditional sugarcane planting in Yunnan is mainly concentrated in February to April, that is, spring planting. However, at this time, the temperature is low, the germination time of seedlings is long, the golden period of large elongation growth in June is missed, and the effective growth period of sugarcane is shortened, which further leads to low yield and sugar production rate of sugarcane. Traditional sugarcane planting is mainly concentrated in February-April, with an average temperature of 14-21°C. The article "Mathematical Model Establishment of Temperature Affects Germination Progress of Sugarcane Seedlings and Its Application i...
