Problems solved by technology

As a jelly-like bacillus, the bacterial solution with a low effective number of viable bacteria is a waste resource, which is generally discharged into the environment as waste water, which not only wastes resources, but also causes harm to the environment.
However, there is currently no specific utilization plan for the bacterial solution

preparation example Construction

[0030] The present invention also provides a method for preparing the above-mentioned liquid fertilizer containing microorganisms, which includes the following steps: (1) After activating the No. 01 strain of Sanju, inoculate it into a seed medium for the first seed fermentation to obtain a first-stage seed fermentation liquid; the seed medium includes the following concentrations of ingredients: 5-12 g / L of sucrose, 0.3-0.8 g / L of dipotassium hydrogen phosphate, 0.1-0.4 g / L of magnesium sulfate, and 0.15-0.35 g / L of sodium chloride and calcium carbonate 0.5~1.2g / L, pH value is 7.0~7.5;

[0031] (2) inoculating the first-stage seed fermentation liquid into the seed medium to carry out second seed fermentation to obtain a second-stage seed fermentation liquid;

[0032] (3) Inoculate the secondary seed fermentation liquid into the fermentation medium to ferment to obtain the fermentation liquid of No. 01 strain Sanju; the fermentation medium includes the following concentrations...

Embodiment 1

[0043] as per figure 1 The shown flow process prepares the liquid fertilizer containing microorganism of high phosphorus type:

[0044] The formula of nitrogen-free medium for activation is: sucrose 10g / L, potassium dihydrogen phosphate 0.5g / L, magnesium sulfate 0.2g / L, sodium chloride 0.2g / L, calcium carbonate 1g / L, agar powder 20g / L , pH 7.5, autoclaved at 121°C for 30 minutes; cultivated at 28-32°C for 48-72 hours;

[0045] The medium formulations of primary fermentation and secondary fermentation are: sucrose 10g / L, potassium dihydrogen phosphate 0.5g / L, magnesium sulfate 0.2g / L, sodium chloride 0.2g / L, calcium carbonate 1g / L; starch 5.5g / L, yeast powder 1.58g / L, soybean meal 5.76g / L, magnesium sulfate 1.4g / L, dipotassium hydrogen phosphate 2.0g / L, calcium carbonate 8.5g / L and sodium chloride 0.2g / L. The culture condition of primary culture is to cultivate at 30~35℃, 150~200r / min for 24~36h, and the condition of secondary culture is to cultivate in seed fermenter at 30~3...

Embodiment 2

[0049] Prepare the liquid fertilizer containing microorganisms of high-nitrogen type, except that the inorganic nutrients are different, all the other conditions are the same as in Example 1, wherein the inorganic nutrients are potassium dihydrogen phosphate, urea and potassium nitrate respectively, wherein by mass percentage, dihydrogen phosphate Potassium accounts for 19.3% of inorganic nutrients, urea accounts for 50.2% of inorganic nutrients, potassium nitrate accounts for 30.5% of inorganic nutrients, and N+P 2 o 5 +K 2 O=150g / L.

Abstract

The invention provides liquid manure containing microorganisms and a preparation method of the liquid manure, and relates to the technical field of bacterial manure preparation. The liquid manure usesbacterial liquid prepared from bacillus mucilaginosus as a solvent, and is further prepared from nitrogen, phosphorus and potassium, the nitrogen, the phosphorus, and the phosphorus are counted as N,P2O5 and K2O correspondingly, and the total concentration of the N, the P2O5 and the K2O is not less than 150g / L; and the living bacterium quantity of three No. 01 bacterial strains in the bacterialliquid is no less than 10*108 / mL. The preparation method is simple, the cost is saved, soil hardening can further be improved, the soil aggregate structure is increased, soil water retention propertyis improved, a rhizosphere microbial system is improved, absorption of nutrients by crops is improved, the growth of the crops is facilitated, and thus the quality and yield of the crops are improved.

Description

technical field [0001] The invention belongs to the technical field of bacterial fertilizer preparation, and in particular relates to a microbial liquid fertilizer and a preparation method thereof. Background technique [0002] Bacillus Mucilaginosus, also known as silicate bacteria, belongs to the genus Bacillus. Its colonies are round, colorless, transparent, and raised. The colonies are smooth, moist and shiny, with neat edges. Bacillus Mucilaginosus can pass through Its own metabolism produces organic acids, amino acids, polysaccharides, hormones and other substances to promote the growth of plants, and can decompose potassium-containing minerals to release potassium and other applied elements. It also has the ability to dissolve phosphorus and fix nitrogen. It is widely used in my country's microbial fertilizers The production strains have played an important role in the field of agricultural microbial preparations. [0003] At present, the state advocates the comprehens...
