Green long-acting and method for preparing same compound fertilizer

Abstract

A green long-acting compound organic fertilizer comprises 50 to 70 parts of animal manure, 15 to 30 parts of mineral and organic matters, 0.001 to 1 parts of trace elements and 10 to 20 parts of water. The preparation method comprises the following steps: adding each component of the compound fertilizer into a vertical mixer or a horizontal mixer according to the ratio of a formula, stirring for 10 to 20 min, discharging, granulating by a disc or a spiral granulator to obtain columnar granules, and oven-drying or air-drying to obtain the green long-acting compound organic fertilizer. The green long-acting compound organic fertilizer has the advantages of high fertilizer efficiency, complete effective components and long validity period, and can improve the soil without polluting the crops and the soil.

Description

technical field [0001] The invention relates to the field of fertilizer for plant growth, specifically green long-acting compound organic fertilizer for plant growth. Background technique [0002] At present, a large amount of chemical fertilizers are used in crop production. Because chemical fertilizers contain a large amount of inorganic salts, long-term large-scale use of chemical fertilizers can increase the content of inorganic salts in the soil, reduce organic matter, lose the acid-base balance of the soil, and cause soil compaction; and the humic acid in the soil , water and nutrients are seriously lacking, leading to soil desertification; and under the stimulation of chemical fertilizers and the lack of humic acid nutrients, crops will also undergo qualitative changes, lose their original nutrients and unique taste, and affect the food. bodily damage.

[0002] At present, a large amount of chemical fertilizers are used in crop production. Because chemical fertilizers contain a large amount of inorganic salts, long-term large-scale use of chemical fertilizers can increase the content of inorganic salts in the soil, reduce organic matter, lose the acid-base balance of the soil, and cause soil compaction; and the humic acid in the soil , water and nutrients are seriously lacking, leading to soil desertification; and under the stimulation of chemical fertilizers and the lack of humic acid nutrients, crops will also undergo qualitative changes, lose their original nutrients and unique taste, and affect the food. physical damage

However, bio-organic fertilizers that are beneficial to soil and crops are far from meeting the needs of large-scale agricultural production due to their low fertilizer efficiency, high cost and low yield due to the constraints of raw materials.

Therefore, people are constantly looking for ways to expand the production of organic fertilizers. On the one hand, a large amount of animal manure is used. However, since fresh poultry manure contains many germs and insect eggs, as well as toxic substances such as ethanol and methane, direct use will reduce soil fertility. 1. Crops are attacked by diseases and insect pests. In addition, fresh poultry manure also contains a large amount of cellulose, protein and other organic matters that are not fully decomposed. It is difficult for crops to absorb. During the fermentation process that continues to decompose in the soil, it will emit heat and reduce the nitrogen content of the soil. , problems such as burning "seeds" and "seedlings" occurred

Therefore, animal manure cannot be directly added to the organic fertilizer, and it must be fermented, which makes the preparation cycle of the organic fertilizer long, troublesome to use, and susceptible to climate influence
