Problems solved by technology

[0003] However, conventional nitrogen fertilizers are generally chemical fertilizers, which lack organic matter and humus. If used for a long time, the soil aggregate structure will be destroyed due to the lack of organic matter and humus, resulting in soil compaction, resulting in a decline in the yield and quality of alfalfa.

Abstract

A method for annual production of alfalfa by using biogas slurry comprises the following steps: step 1, after land is leveled, applying a phosphate fertilizer and a potash fertilizer which are used as base fertilizers into soil at one time, and meanwhile, applying 40-48kg / ha of base fertilizer urea; 2, sowing alfalfa seeds according to the sowing rate of 12-15 kg / ha, wherein the line spacing is 25-30 cm; 3, after the alfalfa is cut once, ditching and dressing urea according to 10-12 kg / ha, meanwhile, dressing biogas slurry according to the nitrogen content of 20-24 kg / ha, and leveling the land after the biogas slurry is immersed into the soil; 4, after the alfalfa is continuously cut twice, ditching and dressing biogas slurry with the nitrogen content of 20-24 kg / ha, and after the biogas slurry is immersed into the soil, leveling the land; and step 5, continuously cutting the alfalfa twice again to complete fertilization and harvesting of the annual alfalfa. The method optimizes the application of nutrients in the annual production process of the alfalfa, realizes high yield of the alfalfa, improves the quality of the alfalfa, reduces the use amount of chemical fertilizer and improves the soil fertility.

Description

technical field [0001] The invention belongs to the technical field of agricultural waste resource treatment, and in particular relates to an annual production method of alfalfa using biogas slurry. Background technique [0002] The hilly area is a typical area with fragile ecological environment. The abandoned soil resources in the hilly area or the extensive traditional agricultural production farmland in the hilly area should be adjusted in time to adjust the industrial structure, develop high-quality artificial grassland, return farmland to grassland, and cooperate with the development of animal husbandry. Nutrient cycling, organic fertilizers to replace chemical fertilizers and other multiple goals. Alfalfa is a perennial herb with the largest planting area of ​​artificial grassland in my country, and is known as the "king of forage grass". Therefore, alfalfa planting is conducive to the sustainable development of the ecological environment and economy in this region. ...
