Composite microbial inoculants of paddy field

Abstract

A composite microbial inoculants of paddy field comprises photosynthetic bacteria, Bacillus subtilis, Bacillus licheniformis and amino acids, zinc sulfate and calcium chloride; 10-20% of photosynthetic bacteria, 10-15% of Bacillus subtilis, 5-8% of Bacillus licheniformis, 6-8% of amino acid, 0. 5-1% of zinc sulfate, 1-3% of calcium chloride and 50-55% of purified water; The photosynthetic bacteria, the bacillus subtilis and the bacillus licheniformis contain more than 200 million effective live bacteria per liter in the compound bacterial agent; The optimum proportion of bacterial species, compound and diluted purified water in the compound bacterial agent was 15% of photosynthetic bacteria, 15% of Bacillus subtilis, 7% of Bacillus licheniformis, 6% of amino acids, 1% of zinc sulfate, 1% of calcium chloride and 55% of purified water. The photosynthetic bacteria used may be Rhodopseudomonas capsularis, Rhodopseudomonas marsh.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a paddy field microbial compound bacterial agent. Background technique [0002] As a large agricultural country, my country produces a large number of crop products for export in addition to self-sufficiency, so crop products occupy a pivotal position in the economic field of our country; with the increase in demand for crop products in recent years, the country has vigorously advocated agricultural production, resulting in In order to increase the yield of crops, people use a large amount of chemical fertilizers to achieve the purpose of increasing production; at the same time, it also leads to the unreasonable use of chemical fertilizers in agricultural activities and the unreasonable development of agricultural resources, resulting in the destruction of soil structure, imbalance of trace elements, and decline in soil fertility. structural decay; [0003] At...

Problems solved by technology

[0004] Most of the common microbial preparations on the market are of a single strain. Although they can be applied to soils in many different situations, they also have a certain effect on improving the soil, but the effect is difficult to meet expectations and can only be used for a single problem. The second is that the survival period in the soil is short, and the effect is obvious in the short term. It cannot effectively improve the soil environment for a long time, and repeated use is required to maintain and strengthen the governance effect.
