Abstract

The invention discloses a straw biogas slurry fertilizer, and a preparation method and application thereof. The straw biogas slurry fertilizer is characterized by being prepared by adding composite bacteria, wood vinegar and carbonized organic matter into a mixture of crop straw and biogas slurry and then carrying out fermenting and decomposing, so that the problems that the drying amount of strawis large, the water content of biogas slurry is high, and the straw and the biogas slurry are difficult to treat separately are solved. The straw biogas slurry fertilizer consists of the following fermentation materials in parts by weight: 0.5-1 part of corn straw, 0.5-1 part of wheat straw, 1-3 parts of biogas slurry, 0.001-0.01 part of compound bacteria, 0.005-0.01 part of wood vinegar and 0.05-0.1 part of carbonized organic matter. The straw biogas slurry fertilizer is applied to soil according to a usage amount of 0.5-1 ton per mu, organic matter in soil can be increased, the soil structure is improved, biological activity of the soil is enhanced, the yield and disease resistance can be increased in cucumber planting, and quality is improved.

Description

technical field [0001] The invention belongs to the field of resource treatment and application of crop straw and biogas slurry. The invention relates to a straw biogas slurry fertilizer and a preparation method and application thereof. Background technique [0002] my country is a large agricultural country and one of the countries with the most abundant straw resources. According to statistics, the total amount of crop straw resources in my country in 1999 was about 640 million tons. Among them, the output of major crops and corresponding straws in Tianjin is about 1.9032 million tons. At present, about 30% of the crop straws are burned, and about 10% of the straws are piled up in ditches and roadsides for a long time, seriously polluting the air and water environment. [0003] Biogas slurry is the supernatant liquid after anaerobic fermentation of human and livestock manure, crop straw, grass and other organic substances to produce biogas. It contains more comprehensive ...
