Carbon-based compound fertilizer containing probiotic organisms and preparation method of carbon-based compound fertilizer

Abstract

The invention discloses a carbon-based compound fertilizer containing probiotic organisms. The carbon-based compound fertilizer comprises biomass carbon black and probiotics, wherein the biomass carbon black is prepared by the following method: carrying out low-temperature carbonization on agricultural wastes as biomass raw materials to form porous biomass carbon black. The probiotics are prepared by the following method: carrying out amplification culture on beneficial microorganisms and fermenting to form probiotic liquid; and mixing and then carrying out solid-liquid separation and expansion drying to form the probiotics, wherein the beneficial microorganisms are selected from one or more of peanibacillus ploymyxa, trichoderma, nitrogen-fixing bacteria, root nodule bacteria, phosphate-solubilizing bacteria, potassium bacteria, cellulose decomposition bacteria, antibiotic-producing strain and photosynthetic bacteria. The carbon-based compound fertilizer disclosed by the invention is made of microporous biomass carbon, and thus the carbon-based compound fertilizer has extremely-strong adsorption capacity and favorable light absorbing and temperature increasing effects; in addition, the probiotics of the carbon-based compound fertilizer are high in cell viability; and the carbon-based compound fertilizer can be preserved at normal temperature for a long time, can be mixed, granulated and dried with other organic and inorganic fertilizers without being influenced and is remarkable in synergistic action.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a biochar-based compound fertilizer containing probiotics; in addition, the invention also relates to a preparation method of the biochar-based compound fertilizer containing probiotics. 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 i...

Problems solved by technology

Therefore, the release rate of nitrogen in ordinary compound (mixed) fertilizers is difficult to maintain a certain scientific ratio with phosphorus and potassium to meet the special needs of nutrients in different crop growth stages

Although the proportions of nitrogen, phosphorus, and potassium are consistent with the fertilizer absorption characteristics of crops in the process of formula design and production of special compound (mixed) fertilizers, when the fertilizer enters the soil, the effect of the fertilizer varies greatly due to various factors.
