Description
Technical field
The present invention relates to a kind of fertilizer, more particularly to a kind of soil improvement composite microbic bacterial fertilizer；The invention further relates to one
The preparation method of kind soil improvement composite microbic bacterial fertilizer.
Background technology
Alkaline soil refers to the soil that soil alkali basicity is more than 7；That is, the hydroxide ion concentration in the soil liquid is more than hydrogen ion
Concentration, then refer to soil of the pH value more than 7.3 in practicality.But in nature, often there is various for the soil of plant growth
The problem of barrier factors of various kinds, limit plant growth, and one serious on basic soil is that nutrient availability is low, and involved
And nutrient species also compare more, such as the universal nitrogen stress of basic soil, phosphorus and potassium；Many soil calcium deficiency and magnesium；Some soil lack
Manganese, what the shortage mainly characteristic that is made up of basic soil and the climatic characteristic of these nutrients were determined.The soil of long-term cropping
Requiring abundant nutrient and soil has certain water retention property, and the shortage of nutrition caused by basic soil is to soil
Ground harvest causes greatly to damage.
The content of the invention
An object of the present invention is to provide a kind of soil improvement composite microbic bacterial fertilizer and preparation method thereof, and the present invention adopts
Use following technical scheme：
A kind of soil improvement composite microbic bacterial fertilizer, described composite microbic bacterial fertilizer include each group of following parts by weight
Point：Alkaline phosphatase 10-15 parts, invertase 10-15 parts, bacillus licheniformis agent 10-15 parts, yeast bacteria agent 10-15 parts, Pu
Public English 20-50 parts, gypsum 10-15 parts, sodium alginate 15-25 parts, calcium sulfate 5-15 parts, humic acid 1-10 parts, palm oil 1-5
Part, ferrous sulfate 1-5 parts, ground phosphate rock 10-20 parts, pine soil 20-30 parts, micro- 1-5 parts.
Preferably, described trace element is calcium, magnesium, potassium, boron, manganese, copper, and its mass ratio is 1:0.6:0.6:0.5:0.4:
0.4。
Preferably, the living bacteria count in bacillus licheniformis agent is not less than 109Spore/gram.
Preferably, the living bacteria count in yeast bacteria agent is not less than 109Spore/gram.
Present invention also offers a kind of preparation method of soil improvement composite microbic bacterial fertilizer, comprise the following steps：
(1) to stock up, yeast bacteria agent is inoculated into manganese ion nutrient solution, the initial concentration of manganese ion is 1.5mg/ml,
It is incubated at 45 DEG C, or obtain stationary phase microbial inoculum；
(2) stocked up by said ratio, dandelion is crushed, cross 50 mesh sieves, the dandelion after sieving is added into constant temperature stirring
In tank, the pure water that volume is 5 times of volume after dandelion crushes is added into agitator tank, temperature stirs immersion under the conditions of being 35 DEG C
10h, first time supernatant is taken, first time supernatant is centrifuged into 15min through centrifuge 1000r/min, obtains second of supernatant, will
Second of supernatant filters through food grade active carbon-coating, takes filtrate, is 73% by mass concentration, volume is 5 times of supernatant volume
Food-grade alcohol add in constant temperature agitator tank, filtrate is added in agitator tank, it is 35 DEG C to be kept stirring in tank temperature of charge, on
Clear liquid adds and finishes 0.5~1h of standing, obtains cotton-shaped mixed liquor, and cotton-shaped mixed liquor centrifuges 3- through 3000~4000r/min of centrifuge
5min, solid is obtained, dry gained solid, obtain dandelion albumen finished product；
(3) by the dandelion albumen obtained by step (2), sodium alginate, calcium sulfate, ferrous sulfate, ground phosphate rock, trace element
It is well mixed after crushing, stirring, adds palm oil, coated fertilizer is made；
(4) alkaline phosphatase, invertase, saccharomycete stationary phase microbial inoculum, bacillus licheniformis agent, 5 parts of water are added to mix
Uniformly, it is granulated, hybrid particles is made；
(5) it is hybrid particles surface made from coated fertilizer even application to step (4) made from step (3), drying is cold
But it is well mixed after with gypsum, humic acid, pine soil, composite microbic bacterial fertilizer is made.
Compared with prior art, the beneficial effects of the invention are as follows：
The organic matter that dandelion albumen can improve soil is horizontal, promotes the growth of plant.Sodium alginate is slightly soluble in water, and it is molten
In alkaline solution, make solution that there is viscosity, prevent soil crust, increase the infiltration rate of soil, prevent soil moisture to be lost in, favorably
Kept in soil water and soil part.Dandelion albumen, sodium alginate, calcium sulfate, ferrous sulfate, ground phosphate rock, trace element stir through crushing
It is well mixed after mixing, adds palm oil and coated fertilizer is made, reasonably can provide nutriment for the growth of soil.
Saccharomycete is first put into manganese ion nutrient solution and cultivated, saccharomycete absorbs to manganese ion, and to logarithm
The strain of phase is collected, and at this time the manganese ion enriching quantity in saccharomycete is maximum, subsequently by alkaline phosphatase, invertase, ferment
Female bacterium stationary phase microbial inoculum, bacillus licheniformis agent are granulated, and form internal layer, and so calcium in the trace element of outer layer is planted
After thing is utilized, the manganese ion being enriched with internal layer can be supplemented the calcium in soil, for needed for plant growth, alkalescence
Phosphatase, invertase can supplement alkaline phosphatase original in soil, the deficiency of invertase, after outer layer is utilized decomposition,
Internal layer is playing a role, and plays the function of sustained release.
