Straw fermented organic fertilizer and preparation method thereof

Abstract

The invention relates to a straw fermented organic fertilizer and a preparation method thereof. The fertilizer is prepared from the following raw materials in parts by weight: 30-50 parts of kanuma soil, 30-50 parts of straws, 3-5 parts of traditional Chinese medicine dregs, 3-5 parts of coconut bran, 0.5-2 parts of a micronutrients fertilizer, 0.5-1 part of a microbial inoculant and 0.5-2 parts of fermenting powder, wherein the traditional Chinese medicine dregs comprise 35% of dried radix rehmanniae dregs, 35% of rhizoma anemarrhenae dregs and 30% of semen litchi dregs. The preparation method comprises the following steps: (1) fermentation of cornstalks; (2) enzymolysis of traditional Chinese medicine dregs; (3) crushing; (4) mixing; (5) granulation; and (6) drying. The straw fermented organic fertilizer provided by the invention is prepared from kanuma soil, straws, traditional Chinese medicine dregs, coconut bran and micronutrients fertilizer, is reasonable in formula, and can meet various demands required by growth of crops.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a rice straw fermented organic fertilizer and a preparation method thereof. Background technique [0002] my country is a big agricultural country, and it is also a big country in the production and use of chemical fertilizers. The domestic use of chemical fertilizers has increased from less than 0.1% in 1949 to the vast majority of crops currently being planted with chemical fertilizers. At present, my country's total output and application of chemical fertilizers rank first in the world. . [0003] With the large-scale application of chemical fertilizers and pesticides in agricultural production, agricultural production has been greatly increased. However, long-term application of chemical fertilizers and pesticides has a relatively large negative effect, which not only causes soil compaction and changes in soil quality, but also reduces the regeneration capacity of the soil...

[0003] With the large-scale application of chemical fertilizers and pesticides in agricultural production, agricultural production has been greatly increased. However, long-term application of chemical fertilizers and pesticides has a relatively large negative effect, which not only causes soil compaction and changes in soil quality, but also reduces the regeneration capacity of the soil. Very low, lower quality of agricultural products
