Organic fertilizer and preparation method thereof

Abstract

The invention belongs to the field of organic fertilizers, and particularly discloses an organic fertilizer and a preparation method thereof. The organic fertilizer comprises the following raw materials in parts by weight: 20-50 parts of animal feces, 10-30 parts of vegetable residue, 20-40 parts of fruit residue, 2-4 parts of trace elements, 3-7 parts of biological bacteria and 10-60 parts of water. The method for producing and using the organic fertilizer is convenient, safe and effective. It is proved that the organic fertilizer has the characteristics of improving the yield of crops, reducing the usage amount of chemical fertilizers, pesticides and the like. The organic fertilizer is prepared by composting and fermentation under the action of biological bacteria, long-term use can solve the problems of soil hardening and hardening caused by the use of chemical fertilizers and pesticides in the production period, and the quality of crops can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of fertilizer preparation, in particular to an agricultural organic fertilizer. Background technique [0002] Fertilizer is the food of plants and an important guarantee for the development of agricultural production and national food security. The wide application of chemical fertilizers in agricultural production is one of the most brilliant achievements of the 21st century. It solves the crisis brought about by the rapid population expansion. However, with the development of agricultural production and the continuous increase of chemical fertilizer types, the structure of fertilization The disadvantages of unreasonable and increasing use of chemical fertilizers are becoming more and more obvious, and the resulting negative effects are gradually emerging, such as: soil compaction, soil nutrient imbalance, soil environment pollution, etc. Therefore, the development of new agricultural organic fertilizers A...

Problems solved by technology

(3) The biological fermentation mode mainly adopts fermentation tank fermentation, direct composting, tower fermentation, etc. The advantages of fermentation tank fermentation are simple process, less investment, and low cost. The main problem is that the product stacking time is too long; tower fermentation occupies an area The area is small, the energy consumption is low, and the pollution is small. The problem is that the cost is high and the equipment corrosion is serious.
