High-efficiency biological organic compound fertilizer and preparation method thereof

Abstract

The invention discloses a high-efficiency biological organic compound fertilizer and a preparation method thereof. The compound fertilizer is characterized by being prepared from the following raw materials in parts by weight: 100-125 parts of crop stalk, 300-400 parts of livestock excrement, 80-100 parts of tobacco offcut, 50-60 parts of toosendan fruit, 80-100 parts of flos chrysanthemi indici, 60-80 parts of urea, 50-75 parts of potassium sulfate, 45-60 parts of ammonium chloride, 35-50 parts of sodium selenite, 15-20 parts of zinc sulfate, 3-4 parts of an EM microbial agent, and 10-12 parts of a soil improvement agent. A product produced via high temperature fermentation by adding the EM microbial agent to the raw materials can overcome the defects of root rot, yellow leaf and seedling death of a crop. The soil improvement agent of the compound fertilizer contains bowlder and a large number of microelements, is beneficial for the human body, can effectively adsorb and solidify toxic heavy metal elements in soil, can reduce absorption of the heavy metal elements by the crop, and can increase the yield of the crop.

Description

technical field [0001] The invention relates to a compound fertilizer and a preparation method thereof, in particular to a high-efficiency bio-organic compound fertilizer and a preparation method thereof. Background technique [0002] Agriculture is the foundation of other industries such as industry and service industry. The rise and fall of agriculture is a major event that directly affects the national economy and people's livelihood. At present, the world is facing severe problems of population increase and environmental degradation. As a country with a large population and a large agricultural country, this problem is particularly prominent. One of the main reasons for this situation is the extensive use of inorganic fertilizers. The deficiencies of this inorganic fertilizer are mainly manifested in the following aspects: 1. The nutrient is single and cannot provide comprehensive and reasonable nutrients for crops; 2. After use, the soil will be acidified or salinized,...

AI Technical Summary

Problems solved by technology

The deficiencies of this inorganic fertilizer are mainly manifested in the following aspects: 1. The nutrient is single and cannot provide comprehensive and reasonable nutrients for crops; 2. After use, the soil will be acidified or salinized, which will reduce the soil quality; 3. 1. Due to the decline of soil quality, the buffering capacity is greatly reduced, and the use of inorganic fertilizers is difficult to achieve results and is likely to cause fertilizer damage; 4. Due to the imbalance of nutrients, the disease resistance of the crops used is reduced; 5. During the production and use of inorganic fertilizers, there will be The environment causes a lot of pollution and wastes a lot of resources; 6. It makes agricultural production fall into a vicious circle and it is difficult to achieve sustainable development
