Problems solved by technology

[0004] The patent application with the publication number CN103992159A discloses a "full element" compound microbial fertilizer and its preparation method and application. The compound microbial fertilizer combines the quick-acting properties of inorganic fertilizers, the long-acting properties of organic fertilizers and the synergistic properties of biological fertilizers In one body, the fertilizer effect is released smoothly, and the effect of promoting growth is good. It is suitable for large-scale use in the planting areas of economic crops such as vegetables and fruit trees. It is of great significance to increase the added value of agricultural products, but it has the disadvantages of long fermentation time and poor fermentation effect.
[0005] The patent application with the publication number CN104098401A discloses a compound microbial fertilizer and its preparation method. The biological fertilizer can improve the soil structure and promote plant growth, but the fertilizer has a long preparation time and has a poor water retention effect on the soil.

Abstract

The invention discloses a preparation method of novel compound bio-fertilizer. The preparation method of the novel compound bio-fertilizer comprises the following steps of raw material pre-treatment,mixing for stirring, fermentation and airing for granulation. By adding a surfactant, microorganism fermentation is promoted, fermentation time is shortened, the nutrient content is improved, growth of harmful bacteria is inhibited, plant absorption is promoted, the soil structure is improved, the moisture and fertility preservation effects of soil are improved, and nutrient absorption of plants is promoted.

Description

Technical field [0001] The invention relates to the field of composite biological fertilizers, in particular to a method for preparing a novel composite biological fertilizer. Background technique [0002] Chemical fertilizers are fertilizers made by chemical and (or) physical methods that contain one or several nutrient elements required for the growth of crops. Long-term application of chemical fertilizers causes soil compaction, reduces soil microbe types and numbers, destroys soil ecosystems, and affects agricultural products. In this case, biological fertilizers have great research significance for quality and environmental pollution. [0003] At present, with the vigorous development of my country's green agriculture, biological fertilizers are receiving more and more attention in agricultural production. In our country, the microbial fertilizer industry is developing very rapidly. The variety, quantity and application range of microbial fertilizer are rare in other countrie...
