Description

A kind of salt-soda soil composite bacterial fertilizer and preparation method thereof

Technical field

The present invention relates to alkaline land improving technical field, specific field is a kind of salt-soda soil composite bacterial fertilizer and its preparation side Method.

Background technology

Salt-soda soil refers to that soil is influenced be subject to nature or the factor such as artificial, causes salts substances gradually to penetrate into soil Go, so that the saliferous and alkalinity of soil are more, and cause this kind of soil not used, China salt-soda soil substantially distributed area Domain is in northwest, northeast, North China and coastal region, and salt-soda soil primarily forms the reason is that more work of the soil of arid area in evaporation Under, moisture is evaporated into vapor, and is emitted into air, but the salinity in water can not be excluded and stayed among soil, By prolonged accumulation, salinity gradually increases in soil, therefore and form salt-soda soil, alkaline land soil structure is poor, brings one Series of problems such as permeable breathable is poor, and easily hardened, microbial activity is poor, and therefore soil is absorbed in vicious circle cannot plant in growth Thing；In recent years, the good result that composite bacterial fertilizer obtains on salt-soda soil is administered gradually is taken seriously, it mainly passes through beneficial microbe Vigorous breeding and metabolism come complete the conversion of material and beneficial metabolites it is continuous formed improve alkaline land soil structure and Salt reduction alkali content, can so promote salt-soda soil to circulate benignly, but micro organism quantity is less and living in existing salt-soda soil composite bacterial fertilizer Property is poor, while cost remains high, and is unfavorable for effectively administering salt-soda soil.

The content of the invention

It is an object of the invention to provide a kind of salt-soda soil composite bacterial fertilizer and preparation method thereof, to solve above-mentioned background technology The problem of middle proposition.

To achieve the above object, the present invention provides following technical solution：A kind of salt-soda soil composite bacterial fertilizer and preparation method thereof, Its raw material forms and corresponding parts by weight are：26~36 parts of Chicken dung, 13~18 parts of decomposed straw powder, urea 12~20 Part, 8~16 parts of potassium dihydrogen phosphate, 5~12 parts of Cosan, 3~7 parts of humic acid, 1~4 part of kelp, 0.1~0.18 part of bean powder, can 0.002~0.006 part of 0.02~0.09 part of soluble starch and microbial bacterial agent.

Preferably, the kelp is dry kelp.

Preferably, azotobacter chroococcum, phosphobacteria and B. mucilaginocus each 2~2.5 hundred million are contained in every gram of microbial bacterial agent.

Preferably, a kind of salt-soda soil composite bacterial fertilizer and preparation method thereof, its preparation method is：

1) kelp is crushed, it is 1~3mm to be crushed to particle diameter, and the kelp after crushing, bean powder and soluble starch is same When add in distilled water, distillation water quality is kelp, 2.5~3 times of bean powder and soluble starch gross mass, stir 5~ 10min, sterilize 12~20min at 120~130 DEG C, spare；

2) microbial bacterial agent is added in step 1) prepared product, is cultivated under 28 DEG C of constant temperature 5~6 days, daily to culture Container is once vibrated, and duration of oscillation is 4~8min；

3) Chicken dung and decomposed straw powder are uniformly mixed, step 2) prepared product is uniformly then sprayed to Chicken dung On the mixture of decomposed stalk；

4) urea, potassium dihydrogen phosphate, Cosan and humic acid are added in step 3) prepared product at the same time, are uniformly mixed i.e. Can.

The beneficial effects of the invention are as follows：A kind of compound organic fungi-manure in salt-soda soil, rich in protein, amino acid, carbon in kelp Hydrate, inorganic salts, vitamin, enzyme and sugared isoreactivity material, after crushing with bean powder and soluble starch it is sterilized after be used for Increase the activity and quantity of microbial bacterial agent, so that azotobacter chroococcum, phosphobacteria and B. mucilaginocus amount reproduction, are sprayed to corruption It is applied in ripe chicken manure and decomposed straw powder in soil being mixed with inorganic quick-acting fertilizer, azotobacter chroococcum, phosphobacteria and potassium are thin Bacterium can decompose the organic matter in Chicken dung and decomposed stalk in breeding and metabolic process, and catabolite is organic acid Salt alkali content in soil can be reduced with organic colloid and improves soil texture, while azotobacter chroococcum, phosphobacteria and B. mucilaginocus Firm nitrogen is each served as to the nitrogen in inorganic quick-acting fertilizer, phosphorus element and potassium, decomposes the effect of slightly solubility phosphorus element and potassium, is carried The utilization rate of high nitrogen, phosphorus element and potassium；Cosan produces sulfuric acid due to oxidation in the soil, can further reduce soil PH value, humic acid often use material for salt reduction alkali, and increase soil organic matter content has the effect of salt reduction alkali at the same time；Salt-soda soil of the present invention Composite bacterial fertilizer, using kelp as improve microbial activity and increase micro organism quantity pioneer's material, with other organic fertilizer and Inorganic fertilizer is together applied in soil, and preferable improved effect can be played to salt-soda soil, and kelp source is wide, cost It is relatively low, with compared with isoreactivity sum number amount microbial bacterial agent, cost is greatly diminished.
