Problems solved by technology

Guangxi is the leading sugarcane production area in China. In order to increase sugarcane yield, the measures adopted are often to apply nitrogen fertilizer multiple times during the sugarcane growth period. Currently, the nitrogen fertilizer application rate in sugarcane areas in my country is generally 500-700kg / hm 2 , in the case of the same yield, the amount of nitrogen fertilizer in my country is 8 to 10 times that of Brazil, and the utilization rate of nitrogen fertilizer in my country is low. A large amount of nitrogen fertilizer input increases the cost of sugarcane production and reduces the economic benefits of sugarcane; Nitrification and denitrification of land reduce soil fertility and cause serious pollution to the ecological environment

Abstract

The invention relates to the technical field of sugarcane planting, and particularly discloses a planting method for promoting nitrogen fixation of sugarcane. The method comprises the following stepsof detoxifying single-bud seed stems of the sugarcane; carrying out sand culture on the single-bud seed stems of the sugarcane, and carrying out nitrogen fixation bacterium inoculation treatment on sugarcane seedlings when each sugarcane seedling grows out 3-4 leaves; scientifically and cooperatively applying nitrogen-phosphorus-potassium base fertilizer, nitrogen fixation microbial fertilizer andorganic fertilizer in a soil preparation trench for providing nutrition required by sugarcane growth, and planting the sugarcane seedlings subjected to inoculation treatment; and after the sugarcaneseedlings grow for 2-3 months, spraying a nitrogen fixation synergist solution to the leaf surfaces of the sugarcane. According to the planting method, the nitrogen fixation capacity of the sugarcaneis improved, the application frequency and the application amount of nitrogen fertilizer are reduced, the yield and quality of the sugarcane are improved, and the economic benefits of the sugarcane are improved.

Description

technical field [0001] The invention belongs to the technical field of sugarcane planting, in particular to a planting method for promoting sugarcane nitrogen fixation. Background technique [0002] Sugarcane is the general term for Saccharum, which is native to tropical and subtropical regions. Sugarcane is an important sugar-producing crop, especially in Guangxi, my country. Planting sugarcane has higher light energy utilization rate per unit area and higher land productivity. Compared with planting food crops, sugarcane is a crop with greater economic benefits. Nitrogen is one of the three essential elements for sugarcane growth. Nitrogen is a component of important living substances such as protein, chlorophyll, nucleic acid, enzymes, and biological hormones. It is the main nutrient element that affects the yield and quality of sugarcane. Guangxi is the leading sugarcane production area in China. In order to increase the sugarcane yield, the measures adopted are often ...
