Fermented organic fertilizer

Abstract

The invention discloses a fermented organic fertilizer. The fermented organic fertilizer comprises the following components in parts by mass: 1000-1500 parts of stalk, 1000-1300 parts of chicken manure, 1000-1500 parts of cattle manure, 800-1200 parts of pig manure, 1200-1800 parts of soybean meal, 35-50 parts of a microbial agent, 10-20 parts of peat humic acid, 50-80 parts of corn meal, 60-90 parts of composite enzyme preparation and 30-60 parts of complex bacteria. The invention also discloses a fermentation method of the fermented organic fertilizer. As the method adopts the microbial bacteria and the composite enzyme preparation, the fermentation efficiency is improved, the fermentation time is effectively reduced, the consumption amount of water, electricity and steam is reduced, the production cost is lowered, and the method is suitable for industrial large-scale production; the fermented organic fertilizer disclosed by the invention has no malodor when used in fields, is cost-saving due to the reduction in the consumption, does not result in soil impoverishment, hardening and salinization, and meets the trend of energy-saving, environment-friendly and sustainable development.

Description

technical field [0001] The invention relates to the technical field of chemical fertilizers, in particular to a fermented organic fertilizer which uses straw and manure as base materials for organic fermentation. Background technique [0002] my country is both a big producer and a big user of chemical fertilizers. For many years, the increase in agricultural production and harvest is inseparable from chemical fertilizers, but chemical fertilizers also bring problems that cannot be ignored. [0003] According to data, in the 10 years from 1984 to 1994, the amount of chemical fertilizers used in my country rose from more than 17 million tons to more than 33 million tons, an increase of 90.7%. More than 440 million tons, an increase of 9.1%. This shows that the diminishing returns of fertilizer use stand out. [0004] A large amount of chemical fertilizers leached into the groundwater or flowed into lakes with rainwater. [0005] Fertilizers that are not used by crops clearl...

Problems solved by technology

[0006] Chemical fertilizers, mainly containing nitrogen, phosphorus, and potassium elements, supplement the lost nutrients for the soil, thereby increasing the yield of crops. However, with the frequent and single use of chemical fertilizers, it has an adverse impact on the soil environment. The soil lacks sufficient nutrients. Under the condition of organic matter, the soil aggregate structure is difficult to form, and the adhesion between soil particles is weakened, which reduces the water retention capacity of the soil.
