Problems solved by technology

At present, the development and utilization of differentiated coal is very limited, the main reason is: the activity of humic acid in differentiated coal is very low, and combined with calcium, magnesium, iron, aluminum, etc., it is insoluble in water, and the effect of direct application in agricultural production is different. very big
[0004] In the existing microbial fertilizers, peat or differentiated coal is only the carrier for adsorbing microorganisms, and the humic acid in it has not been activated, so it cannot improve the soil and promote the growth of crops.
This not only causes a waste of resources but also affects the application effect of microbial fertilizers

Embodiment 1

[0026] In Bacillus subtilis (Ehrenberg) Cohn, covered culture medium (medium is beef extract medium: beef extract: 5 g; sodium chloride: 5 g; peptone: 5 g; agar: 10 g; water: 1000 ml ;pH: 7.5~7.7) Add differentiated coal on the surface, and liquefied black liquid strains will appear after 1 day of cultivation. After 2 days, the medium will all turn brown, and the substances absorbing > 205nm ultraviolet light will increase greatly. The weight loss rate of differentiated coal It is 32.6%, which shows that the water solubility of humic acid is improved through the degradation of microorganisms.

Embodiment 2

[0028] 1. Preparation of compound microbial fertilizer:

[0029] Proportion by weight: 10% of compound microbial bacterial agent, 60% of peat, 20% of nitrogen, phosphorus and potassium inorganic nutrients (10% of pure nutrients), 10% of magnesium sulfate and zinc sulfate, these raw materials are fully mixed and granulated to make compound microbial fertilizer , and its main technical indicators are: the number of effective viable bacteria ≥ 2 × 10 7 per gram, total nutrient ≥ 10%.

[0030] 2. Application of compound microbial fertilizer:

[0031] Ditch 10-20cm, apply compound microbial fertilizer in the ditch, then cover the soil and raise the ridges to transplant seedlings and water.

Abstract

The invention discloses a composite microbial fertilizer. Bacillus subtilis and other bacteria compound to a composite microbial inocula, which then compounds with turf or differentiation coal and inorganic additive, so as to obtain the composite microbial fertilizer. Compared with a present microbial fertilizer, the composite microbial fertilizer of the invention not only has effects of a present microbial fertilizer but also can decompose turf and differentiate humic acid in coal by humic acid decomposer therein, so as to increase fertilizer efficiency of the composite microbial fertilizer, promote growth of crop, increase crop output and improve soil.

Description

technical field [0001] The invention relates to a compound microbial fertilizer and belongs to the field of biotechnology. Background technique [0002] Differentiated coal, lignite and peat are humic acid substances formed by the long-term differentiation of woody or herbaceous plant residues. Humic acid is not only used in petroleum exploration, ceramic industry, medicine and health, and environmental protection, but also has agricultural significance. Wide application prospects. [0003] Humic acid is the basic material of soil physical structure, which can be used to improve soil aggregate structure; enhance soil water and fertilizer retention capacity. Small molecule humic acid has strong physiological functions, which can promote the growth and development of crop roots; improve crop drought resistance; especially reduce leaf transpiration. At present, the development and utilization of differentiated coal is very limited, the main reason is: the activity of humic ac...
