Preparation of total-nutrient efficient biological compound fertilizer and special microbial strain

Abstract

The invention provides preparation of a total-nutrient efficient biological compound fertilizer and a special microbial strain. The fertilizer is a microbiological multiple-strain compound fertilizer which is formed by carrying out fermenting, granulating and coating on oil shale ground slag, chicken manure, multiple strains and inorganic nutrients and is suitable for different soils and the growth of crops. The biological compound fertilizer can obviously improve the content of corresponding quick-acting nutrients in soil, and can increase the yield of various crops by 10-30%. The invention has simple and convenient process, easy operation, wide raw material sources and low manufacture cost.

Description

technical field

[0001] The present invention relates to the preparation of a full-nutritional high-efficiency biological compound fertilizer and special strains in the technical field of biological fertilizers. It is prepared from oil shale slag buried underground for hundreds of millions of years and organic material chicken manure, fermented by multiple strains , A biological full-nutrient compound fertilizer product that is mixed with nitrogen, phosphorus, and potassium after decomposition. Background technique

[0002] At present, all countries in the world are vigorously promoting bio-organic fertilizers, but an obvious defect of organic fertilizers is that they act slowly, and it is difficult to meet the various nutrient supplies for rapid growth of plants in the field. There are many organic fertilizers fermented with crop straw powder in China, but they are often single strains with few strains and weak strains, and some of them are mixed with several strains, becaus...
