Abstract

The invention relates to the technical field of microbial fertilizer and especially relates to a preparation method of concentrated compound microbial fertilizer. The concentrated compound microbial fertilizer comprises 25% to 45% of a carbon source, 15% to 40% of a nitrogen source, 5% to 25% of phosphorus and potassium, 3% to 20% of fulvic acid and 5% to 25% of a mixed inoculant, a slow release agent and trace elements. The concentrated compound microbial fertilizer has characteristics of high viable count and high nitrogen, phosphorus and potassium content and the two indexes are higher than the national standards. The concentrated compound microbial fertilizer is suitable for cultivation of all crops and especially for cultivation of high economic value crops such as vegetables and flowers, belongs to high-quality fertilizer and can be used after being diluted by 100-300 times. The concentrated compound microbial fertilizer has high nutrient content, can fully meet the nutritional needs of various crops, can reduce or replace chemical fertilizer or compound fertilizer, can improve crop quality and can reduce a farming cost and the pests and diseases.

Description

technical field [0001] The invention relates to the technical field of microbial fertilizers, in particular to a preparation method of concentrated compound microbial fertilizers. Background technique [0002] As we all know, the planting and cultivation of most crops currently require fertilization, and most of the existing fertilizers are chemical fertilizers. Chemical fertilizers are manufactured by chemical methods or mined ores, and processed fertilizers are also called inorganic fertilizers, including nitrogen fertilizers, Phosphate fertilizers, potash fertilizers, micro-fertilizers, compound fertilizers, etc., have the following common characteristics: simple ingredients, high nutrient content; fast fertilizer efficiency, strong fertilizer; some fertilizers have acid-base reactions; generally do not contain organic matter, no soil cultivation The role of fat. If it is used for a long time, it will cause soil compaction, increase the cost of farming, reduce the qualit...
