Problems solved by technology

Due to the influence of address, environment and climate, saline-alkali land returns to saline-alkali seriously, which makes the improvement effect of saline-alkali land poor and slow, so the effect of traditional improvement methods is not obvious

Embodiment 1

[0032] The composite bacterial agent for saline-alkali soil improvement includes the following components by weight: strains: Aspergillus 8-12, Pseudomonas fluorescens 18-22, Acinetobacter 18-22, amino acid powder 35-40, subtilis Bacillus 18~22, Bacillus megaterium 8~12, Trichoderma 4~6, Enzyme 4~6; medium: polypeptide enzyme 0.8~1.2, molasses 10~12, rooting powder 1.5~2.5, glucose 2.5 ~3.5, peptone 0.3~0.6.

[0033] Specifically, this embodiment includes the following components in parts by weight:

[0034] Strains: Aspergillus 9, Pseudomonas fluorescens 19, Acinetobacter 19, Amino Acid Powder 36, Bacillus subtilis 19, Bacillus megaterium 9, Trichoderma 4.5, Enzyme 4.5;

[0035] Medium:

[0036] Peptide biological enzyme 0.9, molasses 11, root powder 1.5, glucose 2, peptone 0.3.

Embodiment 2

[0038] The difference between the present embodiment and the first embodiment is that the amount of components added is different, and the present embodiment includes the following components in parts by weight:

[0039] Strains: Aspergillus 10, Pseudomonas fluorescens 20, Acinetobacter 20, amino acid powder 37, Bacillus subtilis 20, Bacillus megaterium 10, Trichoderma 5, Enzyme 5;

[0040] Medium:

[0041] Peptide biological enzyme 1, molasses 11, rooting powder 2, glucose 3, peptone 0.5.

Embodiment 3

[0043] The difference between the present embodiment and the first embodiment is that the amount of components added is different, and the present embodiment includes the following components in parts by weight:

[0044] Strains: Aspergillus 12, Pseudomonas fluorescens 22, Acinetobacter 22, amino acid powder 40, Bacillus subtilis 22, Bacillus megaterium 12, Trichoderma 6, Enzyme 6;

[0045] Medium:

[0046] Peptide biological enzyme 1.2, molasses 12, root powder 2.5, glucose 3.5, peptone 0.6.

[0047] Although above-mentioned three embodiments add component content difference, preparation method is basically similar, all comprises the following steps:

[0048] Step 1. Prepare culture medium

[0049] Take the culture medium components of each weight distribution ratio, undergo sampling sterilization and mixing, and adjust the pH to 6.5-7.5 to form a liquid culture medium;

[0050] Step 2. Cultivate

[0051] Take the strain components in proportion by weight, purify and reju...

Abstract

The invention discloses a composite bacterial agent for improving soil of saline and alkaline land and a preparation method thereof. The composite bacterial agent is prepared from the following components in parts by weight: bacteria strains: 8 to 12 parts of aspergillus, 18 to 22 parts of pseudomonas fluorescens, 18 to 22 parts of acinetobacter, 35 to 40 parts of amino acid powder, 18 to 22 partsof bacillus subtilis, 8 to 12 parts of bacillus megatherium, 4 to 6 parts of compound trichodermin and 4 to 6 parts of enzyme microorganism; culture mediums: 0.8 to 1.2 parts of polypeptide biological enzyme, 10 to 12 parts of molasses, 1.5 to 2.5 parts of rooting powder, 2.5 to 3.5 parts of glucose and 0.3 to 0.6 part of peptone. The composite bacterial agent has the characteristics that the functions of fixing nitrogen, dissolving phosphate, decomposing potassium, decomposing organic matters, inhibiting pests, promoting organic conversion, and accelerating rotting of organic matters to decompose nutrients are realized; when the straw crop on the saline and alkaline land is returned into the field, after the bacterial agent is added, the decomposing rate of the straw being returned intothe field is accelerated, and the improving effect on the soil of the saline and alkaline land is lasting; the soil can be improved, and the crop growth is accelerated.

Description

technical field [0001] The invention relates to a composite bacterial agent for soil improvement in saline-alkali land, and also relates to a preparation process of the composite bacterial agent. Background technique [0002] Saline-alkali soil is a general term for saline soil and alkaline soil. Saline soil mainly refers to salinized soil with high chloride or sulfate content. The soil is alkaline, but the pH value is not necessarily high. Alkaline soil refers to the soil containing carbonate or heavy phosphate, the pH value is high, the soil is alkaline, the organic matter content of saline-alkali soil is small, the soil fertility is low, the physical and chemical properties are poor, and there are many anions and cations harmful to crops. Promote seedlings. [0003] my country has a vast area of ​​saline-alkali land. With the continuous development of agricultural technology, the country pays more and more attention to the development and utilization of saline-alkali la...
