Spray drying-type microbial fertilizer

Abstract

The invention discloses a spray drying-type microbial fertilizer which is prepared from the following raw materials: boric acid, potassium carbonate, ammonium molybdate, citric acid, microelements and a composite microbial agent, wherein the microelements include the elements in parts by weight: 3 parts of zinc, 0.4 part of copper, 0.3 part of iron and 0.3 part of manganese; and the composite microbial agent contains 1 billion / ml of saccharomycetes, 0.5 billion / ml of lactobacillus, 1 billion / ml of bacillus subtilis, 10 billion / ml of photosynthetic bacteria, 1 billion / ml of streptomyces microflavus and 0.5 billion / ml of bacillus laterosporus. The obtained spray drying-type microbial fertilizer has the beneficial effects that the photosynthetic intensity of crop leaf surfaces is improved, the chlorophyll ingredient is added, the stress resistance of crops is strengthened, growth of harmful bacteria is inhibited, and plant diseases and insect pests are reduced. The spray drying-type microbial fertilizer is scientific in raw material proportion and low in production cost, and can replace a chemical fertilizer for use; soil acidification is avoided; nutrients in soil are fixed or transformed, and are directly supplied to the crops for absorption; the fertilization method is simple; and the economic benefits are significant.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a spray-type microbial fertilizer. Background technique [0002] With the improvement of people's living standards, people are increasingly pursuing safe and pollution-free food. Therefore, it has become a development trend to develop efficient and safe fertilizers in crop production. However, most of the existing fertilizers have drug residues, and many of them have strong toxic side effects on the human body. , due to the extensive use of chemical fertilizers, soil compaction, acidification and other phenomena, therefore, to make agricultural production harvest year after year, but also to avoid acidification of the soil, so that sustainable development of agricultural production, it is necessary to find a new fertilizer. Contents of the invention [0003] Purpose of the present invention is exactly a kind of spraying type microbial fertilizer designed in...
