Bio-organic fertilizer and preparation method thereof

Abstract

The invention discloses a bio-organic fertilizer and a preparation method thereof. The organic fertilizer is prepared from the following components by weight: 80-120 parts of wormcast, 600-680 parts of waste, 300-320 parts of nitrogen-phosphorus compound fertilizer, 80-120 parts of river bottom silt, 60-80 parts of plant ash, 100-120 parts of modified zeolite powder, and 100-120 parts of biological organic acid. The preparation method consists of: mixing all the components evenly according to the weight ratio, adding water, stirring the substances evenly, performing stacking, then using yellow mud for screeding and conducting sealing; when the temperature of the material stack rises to 40-45DEG C, stirring and turning over the screeding yellow mud and the mixed materials therein; when the temperature of the material stack is greater than or equal to 55-65DEG C, turning over the materials 2-3 times a day, controlling the fermentation temperature below 70DEG C, then further conducting sealing with yellow mud, and when the materials in the stack become loose and odorless, carrying out stirring and overturning, thus obtaining the bio-organic fertilizer. The bio-organic fertilizer provided by the invention has the characteristics of simple making method and low cost, can improve soil hardening after long-term use, and also can provide crop fertility.

Description

technical field [0001] The invention relates to a bio-organic fertilizer and a preparation method thereof. Background technique [0002] Soil compaction refers to the phenomenon that the soil surface layer is poor in structure due to lack of organic matter. Under the action of external factors such as irrigation or rainfall, the structure is destroyed and the soil material is dispersed. After drying, the soil surface is hardened by the cohesive force, which is not suitable for the growth of crops, flowers and trees. . The main reasons for the formation of soil compaction are as follows: [0003] The soil texture of the farmland is too sticky and the cultivation layer is shallow. The clay content in the clay is relatively large, and the average cultivated layer is less than 20cm, the capillary pores in the soil are less, and the ventilation, water permeability, and temperature increase are poor. After raining or irrigation, the pores are easily blocked, resulting in crustin...

AI Technical Summary

Problems solved by technology

Insufficient supplementation of organic matter in the soil, low soil organic matter content, poor structure, affecting the activity of microorganisms, thereby affecting the formation of soil aggregate structure, causing the soil acidity and alkalinity to be too large or too small, resulting in soil compaction; long-term single soil Partial application of chemical fertilizers

There is a serious shortage of farm manure, heavy nitrogen and light phosphorus and potassium fertilizers, soil organic matter declines, humus cannot be replenished in time, causing soil compaction and cracks
