Biomass charcoal based probiotic preparation and preparation method thereof

Abstract

The invention discloses a biomass charcoal based probiotic preparation, which is composed of biomass carbon black and concentrated probiotic preparation based on a weight ratio of (8.85-9.15): (0.85-1.15). The preparation is prepared by using agricultural wastes as biomass raw materials, conducting low-temperature carbonization to form porous biomass carbon black; conducting amplification culture to beneficial microorganism, and fermenting to produce probiotic solution; mixing above materials and separating solid from liquid; and drying by flash evaporation to obtain concentrated probiotic preparation, wherein the beneficial microorganism is one or more of paenibacillus polymyxa, trichoderma, nitrogen-fixing bacteria, rhizobium, phosphate dissolving bacteria, potassium dissolving bacteria, cellulose decomposition bacteria, antibiotic producing bacteria, and photosynthetic bacteria. In addition, the invention also discloses a preparation method for the biomass charcoal based probiotic preparation. The biomass charcoal based probiotic preparation provided by the invention uses microporous biomass charcoal, which has very strong absorption capacity and very good light absorption and warming effect. The probiotic preparation is high in survival rate of live bacteria, can be preserved for a long time at normal temperature and has evident synegistic effect for fertilizer.

Description

technical field [0001] The invention relates to a probiotic agent, in particular to a biochar-based probiotic agent; in addition, the invention also relates to a preparation method of the biochar-based probiotic agent. Background technique [0002] my country is a country with a large population and a large agriculture. It uses 7% of the world's land to feed 22% of the world's population. The food issue is always a major issue related to the national economy and people's livelihood. my country has 2 billion mu of arable land and needs 150 million tons of fertilizers annually. It is the world's largest importer of fertilizers and producer of nitrogen fertilizers. Even so, the amount of chemical fertilizers still cannot meet the needs of agricultural development. The reason is that the key problem is that the utilization rate of chemical fertilizers is too low. According to surveys, the utilization rate of chemical fertilizers in my country is only 35%-40%, and the rest is f...

Problems solved by technology

According to surveys, the utilization rate of chemical fertilizers in my country is only 35%-40%, and the rest is fixed by the soil, or leached to cause environmental problems such as water pollution and eutrophication of lakes.

In addition, chemical fertilizer is a high-energy-consuming product. Due to the impact of rising raw material prices and environmental pollution, many small chemical fertilizer plants are on the verge of closing down. However, due to economic and energy constraints, the country is currently unable to transform these chemical fertilizer plants. The increase in the total amount of fertilizer in my country
