Problems solved by technology

Extensive use of this type of flushing fertilization can cause soil compaction, deterioration of soil quality, decline of soil fertility, and decline in the quality of agricultural products. At the same time, it seriously breaks the micro-ecological balance of the soil, aggravates the occurrence of crop diseases and insect pests, and also significantly increases the use of pesticides. , which further damages the micro-ecological environment of the soil, forming a vicious circle
When traditional flushing fertilization is used, due to its high water solubility, it is easy to lose with rainwater or evaporate with surface water, so that less than 1 / 3 of the nutrients actually absorbed by the crops
[0003] The existing organic microbial fertilization mainly has the following disadvantages: the strains used are mainly phosphorus-dissolving, potassium-dissolving and nitrogen-fixing, and a small amount of strains with disease resistance are added to a small part, but the effect is slow and the fertilizer loss rate is low. High, and is greatly affected by the method of use and the environment of use

Abstract

The invention relates to a quick-acting multi-microorganism composite water flush fertilizer and a preparation method thereof. The quick-acting multi-microorganism composite water flush fertilizer is characterized by being prepared by mixing bacterial powder which is prepared by fermenting and culturing photosynthetic bacteria, pichiafermentanslodder, lactic acid bacteria, bifidobacterium, bacillus subtilis, bacillus licheniformis, brevibacillus laterosporus, bacillus megaterium, bacillus mucilaginosus, azotobocter chroococcum and actinomycetes. The density of the pichiafermentanslodder ACCC20319T in the quick-acting multi-microorganism composite water flush fertilizer is more than or equal to 2.0*10<8>cfu / g, and the densities of other bacteria are more than or equal to 2.0*10<9>cfu / g. The quick-acting multi-microorganism composite water flush fertilizer can improve the quality and yield of crops and shorten growth period of crops.

Description

technical field [0001] The invention belongs to the field of biological fertilizers, and in particular relates to a quick-acting multi-strain microbial compound fertilization and a preparation method thereof. Background technique [0002] At present, fertilization is mainly used to supply nitrogen, phosphorus, potassium macronutrients and medium and micronutrients to plants. Traditional fertilization is mainly based on inorganic elements. Extensive use of this type of flushing fertilization can cause soil compaction, deterioration of soil quality, decline of soil fertility, and decline in the quality of agricultural products. At the same time, it seriously breaks the micro-ecological balance of the soil, aggravates the occurrence of crop diseases and insect pests, and also significantly increases the use of pesticides. , which further damages the micro-ecological environment of the soil, forming a vicious circle. When traditional flushing fertilization is used, due to its ...
