Drought-resistant organic fertilizer and preparation method thereof

Abstract

The invention discloses a drought-resistant organic fertilizer and a preparation method thereof. The drought-resistant organic fertilizer is prepared from the following components in parts by weight: 1000-2000 parts of chicken manure, 4-10 parts of a water-retaining agent and 1-5 parts of a leavening agent. A production method for preparing the drought-resistant organic fertilizer from the components comprises the following steps: 1, taking chicken manure with the water content of 70%; 2, taking a water-retaining agent with a water absorption rate of 200%; 3, a chicken manure leavening agent; 4, the components are fully and evenly stirred, then the evenly stirred mixture is stacked to form a chicken manure fermentation pile, stacking fermentation is conducted for 20-30 days, and when chicken manure is black brown and free of pungent odor, fermentation is completed to prepare the drought-resistant organic fertilizer, by means of the method, the organic fertilizer manufacturing cost is reduced, fertility is slowly released, water retention and drought resistance are achieved, and the crop yield is increased.

Description

technical field [0001] The invention relates to a drought-resistant organic fertilizer and a preparation method thereof. It belongs to the technical field of organic fertilizer production. Background technique [0002] At present, most of the fertilizers used for crops rely on inorganic fertilizers, resulting in the reduction of soil organic matter, the decline of fertilizer and water retention performance, the nutrients applied to the soil are lost in a large amount through seepage, fixation or volatilization, and the accumulation of heavy metal elements exceeds the standard. Degradation leads to excessive pesticide residues, which poses a threat to the health of consumers. Long-term application of inorganic fertilizers leads to compaction of farmland soil and poor permeability, which is not conducive to the growth of crops, affecting quality and yield.

Problems solved by technology

[0002] At present, most of the fertilizers used for crops rely on inorganic fertilizers, resulting in the reduction of soil organic matter, the decline of fertilizer and water retention performance, the nutrients applied to the soil are lost in a large amount through seepage, fixation or volatilization, and the accumulation of heavy metal elements exceeds the standard. Pesticide residues exceed the standard due to degradation, which poses a threat to the health of consumers. Long-term application of inorganic fertilizers leads to compaction of farmland soil and poor permeability, which is not conducive to the growth of crops, affecting quality and output.

[0003] The existing well-known organic fertilizer production methods include aerobic fermentation method. By adding dry matter, the water content of feces and sludge is reduced to create a suitable fermentation environment for aerobic bacteria. The disadvantage of this method is to create a loose and breathable fertilizer. In the fermentation state, a large amount of dry matter needs to be added, such as rice husk and straw, which greatly increases the production cost; there is also an anaerobic fermentation method, which uses a biogas digester for fermentation. The disadvantage of this method is that it will produce a large amount of biogas slurry, Biogas residue, with high water content, is not conducive to packaging and sales
