Embodiment 1

[0024] Embodiment 1, preparation microbial mixed bacterial agent

[0025] The active ingredient of the microbial mixed bacterial agent consists of bacillus polymyxa, bacillus licheniformis and bacillus subtilis.

[0026] Preparation:

[0027] 1. Various bacteria (Bacillus polymyxa, Bacillus licheniformis or Bacillus subtilis) were made into powdered active bacteria, the method is as follows: (1) Inoculate the strains into ordinary broth medium, culture at 37°C for 24 (2) Inoculate the seed liquid into the expansion medium (the solvent is water, the solute and its concentration are as follows: soybean meal liquid 20g / L, glucose 5g / L, corn Powder 2g / L, MgSO 4 0.16g / 100mL, K 2 HPO 4 0.28g / 100mL and KH 2 PO 4 0.28g / 100mL), cultivated at 37°C for 48 hours; then inoculated the culture system of step (2) into sterilized bran and cultivated at 37°C for 72 hours to obtain a powdery active bacterial agent.

[0028] 2. According to the ratio of CFU ratio of 1:1:1, the powdery acti...

Embodiment 2

[0031] Embodiment 2, preparation biological organic fertilizer

[0032] 1. Preparation of sludge fermentation agent

[0033] The active ingredient of the starter is composed of aerobic bacteria and facultative aerobic bacteria, the aerobic bacteria are Bacillus subtilis, Aspergillus niger and Sporosporium thermophilic; the facultative aerobic bacteria is Bacillus stearothermophilus and Saccharomyces cerevisiae.

[0034] The above-mentioned 5 kinds of bacteria were all purchased from China Industrial Microorganism Culture Collection Management Center (CICC). The deposit number of Saccharomyces cerevisiae is 2441, and the deposit number of Saccharomyces cerevisiae is 1923.

[0035] Preparation:

[0036] 1. Various bacteria are separately made into powdered active bacteria: inoculate various bacteria (Bacillus subtilis, Bacillus stearothermophilus, Aspergillus niger, Saccharomyces cerevisiae, Sporidium thermophila) into bran for fermentation made.

[0037] 2. According to th...

Embodiment 3

[0048] Embodiment 3, the application of microbial soil conditioner first

[0049] The rape variety used in this example is Deyou 16.

[0050] The organic fertilizer used in this example is "Nongfengbao" organic fertilizer produced by Hainan Nongfengbao Fertilizer Co., Ltd. (registration number: Qiongnongfei (2003) Zhunzi No. 0042.

[0051] Deyou No. 16: Beijing ORG Seed Industry Co., Ltd., variety approval number: Ganshenyou 2005004.

[0052] Treatment group: After harvesting rapeseed, use 150 kilograms of organic fertilizer and 10 kilograms of microbial soil conditioner A prepared in Example 2 per mu to prepare the site; then plant rapeseed again (planting 6000 plants per mu), manage normally, grow During the period, rapeseed rot disease was observed and recorded.

[0053] Control group: the only difference with the treatment group is that the microbial soil conditioner A prepared in Example 2 is not used.

[0054] The onset of rot disease is characterized by: for a rapese...

Abstract

The invention discloses a microbial soil conditioner and a preparation method thereof. The invention provides a microbial mixed inoculant, comprising bacillus polymyxa, bacillus licheniformis and bacillus subtilis as active components. The preparation of the microbial soil conditioner provided by the invention comprises the following steps: mixing sludge with auxiliary materials, then inoculating a sludge starter culture to ferment to obtain decomposed sludge, inoculating the microbial mixed inoculant to proceed with culturing to obtain the microbial soil conditioner, wherein the active components of the sludge starter culture comprise bacillus subtilis, bacillus stearothermophilus, aspergillus niger, thermophilic sporotrichum and Saccharomyces cerevisiae. The invention has important values for promoting the healthy development of agricultural and forestry production of China.

Description

technical field [0001] The invention relates to a microbial soil conditioner and a preparation method thereof. Background technique [0002] Soil pollution, degradation and unreasonable planting methods have caused serious adverse effects on agricultural and forestry production. my country has a large area of ​​low-yield fields with poor properties, adversity soil and barrier soil. In recent years, due to improper application of chemical fertilizers and reduced input of organic fertilizers, the properties of many farmlands have deteriorated, and soil fertility has shown a downward trend. In this case, people continue to explore and research, and found that in addition to improving soil fertility through rational fertilization and tillage, the scientific use of soil conditioners is also an effective measure. And various conditioners for improving and remediating soil have been developed. Soil conditioners can improve soil and increase soil fertility. Although they do not d...
