Maotai-flavor distiller's grain organic fertilizer and preparation method thereof

Abstract

The invention discloses a Maotai-flavor distiller's grain organic fertilizer and a preparation method thereof. The fermentation raw material of the organic fertilizer comprises the following components: 80-90 parts of Maotai-flavor distiller's grains, 5-10 parts of rape seed cake, 4-8 parts of bone meal, 3-4 parts of straw, 3-4 parts of sawmilling powder, 5-10 parts of corncob core, 2-4 parts of egg shell, 1-2 parts of quicklime, 0.1-0.2 part of decomposing microbial inoculum and 2-4 parts of kitchen waste. The organic fertilizer contains few heavy metals and enough nutrients. The preparation method of the organic fertilizer comprises the steps of raw material crushing, raw material mixing, microbial inoculum inoculation, fermentation and granulation, drying and the like; and the preparation method realizes thorough composting and can avoid secondary fermentation after the organic fertilizer is applied to soil.

Description

technical field [0001] The invention belongs to the field of organic fertilizers, in particular to a Maotai-flavored distiller's grains organic fertilizer and a preparation method thereof. Background technique [0002] With the improvement of people's quality of life, people's requirements for crop growth quality and growth efficiency are also constantly increasing when planting crops. In order to improve the growth quality and growth efficiency of crops, people usually apply fertilizers to crops in the growth period. [0003] The fertilizers currently used include inorganic fertilizers and organic fertilizers. Inorganic fertilizers refer to inorganic salt fertilizers containing nitrogen, phosphorus, potassium and other nutrients. Inorganic fertilizers are mostly extracted or synthesized from minerals. Inorganic fertilizers have high nutrients and quick results. They can provide a large amount of nitrogen, phosphorus, potassium and other elements needed by crops, and can pro...

Problems solved by technology

However, poultry manure such as chicken manure contains a large amount of heavy metals, which will lead to excessive heavy metal content in crops, and if used for a long time, it will also cause excessive heavy metal content in soil

In addition, forced drying makes various organic raw materials not fully decomposed, which will cause secondary fermentation of organic fertilizers after they are applied to the soil, burning the roots of crops, and fermentation requires nitrogen sources, which compete with crops for nutrients and affect the early growth of crops. Make organic fertilizer can not play its role
