Problems solved by technology

However, the suitable growth environment for Bacillus is a high-protein culture solution and an environment with a pH value of 7-9. It grows slowly in acidic soil, so it needs to be expanded to a certain number in advance and provide enough protein environment to improve its effect.

Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with specific embodiments.

[0015] The present invention is a microbial organic fertilizer capable of improving soil alkalinity, comprising an alkali-producing Bacillus subtilis;

[0016] The first step is to inoculate Bacillus subtilis into the culture medium and carry out liquid fermentation. The production conditions are as follows: the pH value is between 7.7 and 8.2, the temperature is 20 to 35°C, and the fermentation time is 5 to 7 days to obtain the original fermentation liquid, wherein The stirring speed is 120-300 rpm, and the substance content in 1L of the culture solution is: peptone 3-7g, bean cake 8-15g, yeast powder 1-2.5g, molasses 10-20g, KH 2 PO 4 0.01g, sodium chloride 0.5~1.5g, K 2 HPO 4 0.01g; expand the culture of the strain HNPY23, add the original fermentation broth to the newly prepared fermentation broth according to the total amount of 1:4, and place it in a gr...

Abstract

The invention discloses a microbial strain organic fertilizer for improving soil alkalinity. The strain in the organic fertilizer can produce alkali under different fermentation conditions, and can be used against a soil acidification problem of over-farmed soil. Bacillus can survive and grow under stresses, can provide various enzymes for soil, and assists in improving soil microbial diversity. An alkali-producing bacillus is screened and is applied in acidic soil, and crop rhizosphere micro-ecology of the acidic soil can be tuned and optimized. Soil urease activity can be improved, such that an excellent liquid microbial fertilizer is provided for the growth of crops such as Indian lettuce and lettuce in the acidic soil. With the organic fertilizer prepared with the strain HNPY23, leaf tissue chlorophyll content, leaf Vc content and yield of the crops such as Indian lettuce and lettuce can be substantially improved. With the fertilizer, both quality and yield can be improved.

Description

technical field [0001] The invention relates to the field of microbial bacteria and organic fertilizers, in particular to a microbial organic fertilizer capable of fine-tuning the rhizosphere microenvironment of acidic soil by producing alkali and promoting the growth of lettuce, lettuce and other crops in acidic soil and its application. Background technique [0002] Bacillus widely exists in nature, with rapid reproduction, fast metabolism, 100,000-fold multiplication in four hours, and standard bacteria can only multiply six times in four hours. The important feature of this genus of bacteria is that they can produce spores with special resistance to adverse conditions. They can withstand low temperature -60°C and high temperature +280°C in a non-humid state. Oxygen reproduction), low oxygen tolerance (anaerobic reproduction). In particular, many bacteria of this genus can hydrolyze starch, decompose protein, pectin, alginate, etc., and are used in industry to extract am...
