Problems solved by technology

[0004] At present, domestic and foreign studies on salinity-alkali control in coastal areas mostly focus on soil improvement, salt-tolerant plant varieties, engineering technology, etc.
The conventional chemical improvement method has a very significant effect in the short term, but its shortcomings are also obvious, the cost is too high, and the impact on the soil environment needs to be investigated and studied
There are few reports on microbial fertilizers aimed at improving saline-alkali land and promoting crop production

Embodiment 1

[0025] Embodiment 1: preparation bacterial suspension

[0026] According to the characteristics of the bacteria and the promotion or antagonistic effect of the flora, the following strains were selected to prepare the mixed bacterial suspension. See Table 1 for the names of the strains. The strains were purchased from the China Common Microorganism Culture Collection Management Center. body, the specific steps are as follows:

[0027] Step 1.1 Under aseptic operation, use a sterile micropipette to draw 50 μL (or 1-2 drops) of the bacterial solution from the dissolved tube, and drop it into the solid specified medium (the medium number and temperature are shown in the strain order form) ) near a certain edge, inoculated on the culture medium by streaking method;

[0028] Step 1.2 Place the inoculated medium in an incubator at a specified temperature for cultivation;

[0029] Step 1.3 In a sterile environment, wipe the outer tube with cotton dipped in 75% alcohol, and heat the...

Embodiment 2

[0036] Embodiment 2, the acquisition of decomposed matter

[0037] Calculated in parts by weight, take 34-54 parts of solid farmyard manure, add 20-30 parts of fallen leaf compost, 4-6 parts of mushroom mycelium, 2-3 parts of superphosphate or 1.5-2.5 parts of potassium dihydrogen phosphate, water 1-2 portions, mix well, ferment at 60-70°C for 3-4 days to obtain decomposed matter.

Embodiment 3

[0038] Embodiment 3, the acquisition of biological fertilizer

[0039] Proceed as follows:

[0040] Step 3.1 Take 10 parts of silicate minerals, 6 parts of calcite, 15-20 parts of pumice, 5-8 parts of potassium feldspar, 9 parts of Phytophthora, 6 parts of sepiolite, 14 parts of vermiculite, 7 parts of serpentine, Grind 6 parts of Hanshui stone into 180-200 mesh powder, mix well to make mineral fertilizer.

[0041] Step 3.2 10 parts of decomposed matter were crushed to 0.5mm.

[0042] Step 3.3 15 parts of superphosphate, 23 parts of urea formaldehyde, 0.5-1 part of ammonium molybdate, 1 part of EDTA-metal chelate, grind into 160-170 mesh powder, and mix to make slow-release fertilizer.

[0043] Step 3.4 Put the mineral fertilizer, decomposed substance and slow-release fertilizer into the blender and stir and mix the fertilizer matrix in proportion.

[0044] Step 3.5 Mix the fertilizer matrix with the bacterial suspension in Example 1 at a ratio of 3:1 to make a biological fer...

Abstract

The invention provides a preparation method for a bio-fertilizer, belongs to the technical field of the bio-fertilizer, and particularly relates to a preparation method for a bio-fertilizer used for improving saline alkali soil and remedying soil fertility. The bio-fertilizer prepared by the provided preparation method is capable of increasing the supply amount of plant nutrient through the vital movement of microorganisms, inhibiting the activity of harmful microorganisms, improving the physical behavior of the soil of the saline-alkali stress, increasing the soil fertility, and improving the micro-ecological environment.

Description

technical field [0001] The invention belongs to the technical field of biological fertilizers, and in particular relates to a preparation method of biological fertilizers. Background technique [0002] Saline-alkali soil is a soil that is formed by the process of salinization (alkali) under the combined action of various natural environmental factors and human activities. It has a salinized layer or an alkalized layer, contains a large amount of soluble salts, and inhibits the normal growth of plants. . At home and abroad, saline-alkali soil is often used as a general term for various saline soils and alkaline soils, as well as other salinized and alkalized soils to varying degrees. Land salinization is a kind of land desertification, which is the biggest problem in land degradation. It leads to the decline of soil fertility, difficulty in absorbing water for plant roots, and even the inability to grow, resulting in reduced crop production and even abandonment of land, seri...
