Abstract

The invention discloses microbial compound bacterial fertilizer. The microbial compound bacterial fertilizer is prepared from the following components in parts by weight: 5 to 25 parts of compound microorganisms, 65 to 95 parts of compound nutrient carrier, 0.5 to 2 parts of EDTA (Ethylene Diamine Tetraacetic Acid)-metal chelate and 5 to 10 parts of diatomite. The invention further discloses a preparation method of the microbial compound bacterial fertilizer and application of the microbial compound bacterial fertilizer to soil improvement and promotion of crop growth and development. Comparedwith the prior art, the microbial compound bacterial fertilizer has the advantages that ingredients play a synergetic role, so that soil can be effectively improved, hardening parts can be loosened,nutrients can be balanced, the soil fertility can be improved, the soil components can be activated, the water and fertilizer retention capabilities of soil can be improved, and production increase ofthe crops can be promoted. Meanwhile, a production process is simple, raw materials are easy to obtain, the ingredients are derived from low-cost industrial and agricultural waste, the equipment andsite requirements are not high, operation is safe, and the application effect is remarkable. The microbial compound bacterial fertilizer can be produced on a large scale in enterprises, and can be prepared at home by individuals or peasants.

Description

technical field [0001] The invention belongs to the technical field of microbial fertilizers, and in particular relates to a microbial compound bacterial fertilizer and its preparation method and application. Background technique [0002] Because chemical fertilizers can quickly promote crop growth and increase crop yields, farmers in my country have used chemical fertilizers for a long time, and the lack of organic fertilizers has resulted in imbalances in the proportion of various nutrients, soil physical and chemical properties and soil microbial flora have been damaged to varying degrees. To some extent, it affects the quality of agricultural products. Crop control of pests and diseases mainly uses chemical agents and toxic pesticides, which are applied to the soil or on crops. Long-term use of pesticides is likely to cause resistance of pests and diseases. The application of chemical fertilizers usually breaks the balance of flora in the soil micro-ecosystem, which will...
