Microbial inoculums and preparation method thereof

Abstract

The invention discloses a microbial inoculum and a preparation method thereof. The microbial inoculum is prepared from bacterial liquid containing Bacillus subtilis, Bacillus megaterium, Azotobocter chroococcum and Bacillus circulans Jordan and an adsorbent. The adsorbent comprises the following components: humic acid, lignin and diatomite of which the weight ratio is equal to 5:3:1. The proportion of the adsorbent and the bacterial liquid is that: each 100 kg of adsorbent is added with 15 L of bacterial liquid. The effective viable count of the microbial inoculums is between 200,000,000 and 250,000,000 per gram. The microbial inoculum can not only activate the soil and improve the fertilizer utilization, but also effectively inhibit soil-borne disease from breeding and spreading, thereby having the effect of increasing yield.

Description

technical field [0001] The invention relates to a microbial bacterial agent, which belongs to the field of biology. Background technique [0002] my country's chemical fertilizer consumption ranks first in the world, domestic chemical fertilizer can only meet 70% of domestic demand, and the total value of imported chemical fertilizer is more than 3 billion US dollars every year. The utilization rate of chemical fertilizers in my country is low, the utilization rate of nitrogen fertilizer is only about 30%, the utilization rate of phosphorus fertilizer is only 19%, a large amount of phosphorus is absorbed and fixed by the soil and converted into ineffective phosphorus, and the utilization rate of potassium is only about 35%. Lost by leaching or solidified by soil. [0003] The unreasonable use of fertilizers in production has caused varying degrees of damage to the soil ecological environment, ecological physical and chemical properties, and soil microbial flora.

AI Technical Summary

Problems solved by technology

The utilization rate of chemical fertilizers in my country is low, the utilization rate of nitrogen fertilizer is only about 30%, the utilization rate of phosphorus fertilizer is only 19%, a large amount of phosphorus is absorbed and fixed by the soil and converted into ineffective phosphorus, and the utilization rate of potassium is only about 35%. Lost by leaching or solidified by soil

[0003] The unreasonable use of fertilizers in production has caused varying degrees of damage to the soil ecological environment, ecological physical and chemical properties, and soil microbial flora. Salinization, acidification, and compaction of the soil have occurred. The proportion of elements is seriously out of balance, and the sustainable production capacity of the soil is reduced

Extensive use of chemical fertilizers also causes environmental pollution
