Abstract

The invention provides a crop organic fertilizer and a preparation method thereof and especially relates to an environment friendly and high-efficiency organic fertilizer prepared by the use of biogas residue, biogas slurry and straw. The organic fertilizer has an obvious effect of improving soil hardening and salinization. The invention has the following beneficial effects: 1, by the use of efficient complex microbial starter cultures which are beneficial to soil, biogas residue, biogas slurry and straw can be fermented within a short period of time to form an organic fertilizer with high fertilizer efficiency; 2, the formula of the organic fertilizer is scientific and reasonable, has strong pertinence and high content of organic matter, and can promote increase of crop yield and enhance quality of agricultural products; 3, the organic fertilizer produced by the invention can improve soil structure, promote formation of granular structure, raise soil fertility, adjust pH value of soil and boost fertilizer maintenance and water retention capacity of soil; and 4, agricultural wastes are fully utilized, the problem of environmental pollution caused by agricultural waste is solved, cyclic utilization of waste resources is realized, and the organic fertilizer is in accordance with the idea of national green development and is beneficial to human.

Description

technical field [0001] The invention relates to an organic fertilizer for crops, in particular to an organic fertilizer for crops made from biogas residue, biogas slurry and straw. Background technique [0002] Like land, forests, and coal, organic fertilizers are an important resource for the country. Unlike many countries, the contradiction between population and land in our country is very prominent. Relying on grassland rotation, extensive planting and low harvest, and farming and leisure methods cannot solve the problem of food and clothing for our people. Relying on increasing the yield of agricultural products per unit area, cultivating fertile soil, and vigorously improving low- and medium-yielding fields are important measures. Like knowing anything in the world, the understanding of organic fertilizers is also tortuous. In the early days of the founding of the People's Republic of China, farmers were very enthusiastic about production and hoped to obtain more agr...
