Problems solved by technology

[0004] The problems existing in the existing technology are: the existing chemical fertilizers cannot improve the properties of saline-alkali soil, nor can they reduce the salinity of the soil, and cause pollution to the environment, and reactivation will harm crops, which is not conducive to crop growth
[0005] Difficulty in solving the above technical problems: saline-alkali soil has high pH and salt content, poor soil nutrients, physical and chemical methods can not solve the problem fundamentally

preparation example Construction

[0053] like figure 1 As shown, the preparation method of the improved saline-alkali land microbial fertilizer provided by the embodiments of the present invention specifically includes:

[0054] S101, preparing microbial fermentation liquid, corn stalks, urea, and calcium phosphate according to the weight percentage; crushing the corn stalks with a micro-powder prototype machine for later use.

[0055] S102, activate wp-3 strain in LB solid medium.

[0056] S103, inoculate the activated strain into the fermentation broth adjusted to pH 7.5-7.83L with ammonia water and ferment for 72 hours, the total number of live bacteria of the strain shall not be less than 2×10 8 CFU / mL.

[0057] S104, adding 150g of urea and 30g of calcium phosphate to the fermentation broth obtained in step S103.

[0058] S105, pour the solution obtained in step S104 into 200 g of corn stalk powder, place it in a fermentation bag, and after fermentation for 5-7 days, air-dry it naturally until the wate...

Embodiment 1

[0062] The invention provides an improved microbial fertilizer for saline-alkali land, which consists of the following components by weight percentage: 85-90% of microbial fermentation liquid, 6-7% of corn straw, 4-5% of urea and 1-2% of calcium phosphate.

[0063] The preparation method of above-mentioned microbial fertilizer, comprises the following steps:

[0064] The activated strain wp-3 was inoculated in the fermentation broth, and fermented at 30° C. in a shaker at 180 r / min for 72 hours.

[0065] Fermentation broth: 5g of yeast extract, 10g of tryptone, 1000mL of distilled water, adjusted to pH 7.5-7.8 with ammonia water, and sterilized at 121°C for 20 minutes.

[0066] Add 150g urea and 30g calcium phosphate to the above-mentioned fermented liquid.

[0067] 200 g of corn stalks were pulverized with a micro-powder sample machine and placed in a fermentation bag.

[0068] Pour the above fermented liquid with urea and calcium phosphate into a fermenting bag, finish fer...

Embodiment 2

[0070] The application of the saline-alkali soil microbial fertilizer provided by the embodiment of the present invention in wheat growth and saline-alkali soil improvement. include:

[0071] (1) Wheat pot experiment

[0072] The soil and the microbial fertilizer were mixed at a ratio of 3:1 to treat the bacterial fertilizer, and the soil without bacterial fertilizer was set as the control.

[0073] Add 2% sodium chloride to the soil without bacterial manure and the soil with bacterial manure.

[0074] Wheat seeds were sown in pots containing an equal amount of 2kg of soil, 20 seeds per pot, and 3 replicates were set for the control and treatment. Timely and equal watering, thinning after 7 days, keeping 6 plants with uniform growth in each pot, measuring their growth and soil physical and chemical properties after 30 days. The effect of promoting growth is as follows figure 2 .

[0075] (2) Determination of wheat growth indicators

[0076] Microbial fertilizer can prom...

Abstract

The invention belongs to the technical field of saline-alkali soil improvement, and discloses microbial fertilizer for improving saline-alkali soil and a preparation method and application thereof. The microbial fertilizer comprises the following components by weight: 85-90% of a microbial fermentation liquor, 6-7% of corn straw, 4-5% of urea, and 1-2% of calcium phosphate. The microbial fermentation liquor is prepared by fermentation of salt-tolerant growth-promoting bacteria staphylococcus wp-3. The microbial fertilizer provided by the invention is remarkable in soil improvement effect and capable of promoting crop growth. According to the application of the microbial fertilizer in wheat growth, the microbial fertilizer has a promoting effect on wheat growth, and the fresh weight of seedlings, the fresh weight of roots, the plant height and the root length are remarkably increased compared with those of a contrast, the pH of the soil is remarkably reduced by 3.6 percent, and the contents of quick-acting phosphorus, quick-acting potassium, organic matters and alkaline hydrolysis nitrogen are remarkably increased by 240.05 percent, 545.47 percent, 75.80 percent and 44.35 percent respectively.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali soil improvement, and in particular relates to a microbial fertilizer for improving saline-alkali soil, a preparation method and an application thereof. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: soil salinization is a worldwide problem, and my country is one of the countries with large saline-alkali land in the world, and the total area of ​​saline soil is about 0.99*10 8 hm 2 . Due to the accumulation of a large amount of salt in the soil, a series of soil physical properties deteriorate: sticky structure, poor air permeability, high bulk density, slow rise in soil temperature, poor activity of aerobic microorganisms in the soil, slow differential release, low permeability coefficient, capillary action Strong, it also leads to the aggravation of surface soil salinization. For a long time, many scholars at home and ab...
