Bio-organic fertilizer and preparation method thereof

Abstract

The invention discloses a bio-organic fertilizer which is prepared from the following components in parts by weight: 800-820 parts of agricultural wastes, 12-18 parts of calcium superphosphate, 4-6 parts of potassium mineral powder, 4-6 parts of fermenting enzyme agent, 40-60 parts of mineral powder, 90-110 parts of boron soil powder, 8-12 parts of humic acid and 4-6 parts of culture. The preparation method comprises the following steps: uniformly mixing all raw materials, adding water for uniformly stirring, stacking the materials into cubic piles at the temperature of more than or equal to 15 DEG C, and making air holes on the cubic piles; turning for 1-2 times per day when the temperature of the material piles reaches 50 DEG C, turning for 4-5 times per day when the temperature of the material piles is more than or equal to 65 DEG C, controlling the fermentation temperature to be 70 DEG C or below; and preparing the fertilizer when the materials in the material piles are loose and the original odor of the materials is avoided. The bio-organic fertilizer has the advantages that the bio-organic fertilizer is full in nutrient elements and is green and environment-friendly, the soil can be improved, and soil hardening caused by use of the fertilizer is improved.

Description

technical field

[0001] The invention relates to the field of fertilizers, and in particular provides a bio-organic fertilizer and a preparation method thereof. Background technique

[0002] At present, in terms of crop planting in my country, most of them still use chemical fertilizers. Although there is a certain amount of rent in terms of increasing production and income, long-term use will cause the following problems:

[0003] 1. Destroy the soil, but the content of organic matter in the soil will decrease, resulting in an imbalance in the proportion of nutrients, acidification and hardening of the soil, which will affect the yield of crops;

[0004] 2. The agricultural ecological environment is deteriorating. After applying chemical fertilizers to farmland, the actual utilization rate is only 30% on average, and most of them flow into rivers with farmland drainage, polluting the environment and endangering people's health.

[0005] Therefore how to improve the fertiliz...
