Description
Technical field
It is more particularly to a kind of to contain rhizobium the present invention relates to microbial manure, sustained-controll-release fertiliser and its production technical field
Film-coated controlled release fertilizer and its production technology.
Background technology
Agricultural is human survival, the basis of economic development, and agricultural must walk the road of sustainable development.With the increasing of population
Long, people are also constantly increasing to the demand of grain, in order to meet that this demand people must just improve agricultural productivity, and
Application fertilizer is one of key measures of agricultural volume increase.In recent years, sustained-controll-release fertiliser has turned into the focus of fertilizer circle research,
It has the characteristics that to improve utilization rate of fertilizer, reduces environmental pollution, improves crop yield.
But sustained-controll-release fertiliser production cost is high, price corresponds generally to 2~4 times of common fertilizer price, limits it
Widely use, more as specific use (such as lawn, flowers).Secondly as after sustained-controll-release fertiliser is manured into soil, it is wrapped
Membrane material is not decomposed by the microorganisms or extremely difficult decomposition, therefore the coated fertilizer can be to environment structure secondary pollution.In addition, Controlled Release Fertilizer
The controlled-release effect of material is also not ideal, and nutrient release rate also less has synchronism with crop demand.In fertilizer efficiency evaluation, nutrient
Releasing mechanism, fertilizer control release performance etc. also need to further research and improved.From this, exploitation is cheap and can quilt
Biodegradable natural or half-natural coated fertilizer, for example, slowly being decomposed using microorganism, cheap and easily-available, environmental pollution is small
Organic coated material, and then coating is destroyed, the urea of parcel is progressively discharged, and then regulate and control Nitrogen releasing, and reduce coating material
Expect the accumulation in soil, optimize nutrients release pattern to adapt to the demand of crop, avoid polluting soil and environment, will
The strong coordinated development for promoting agricultural and environment.
In recent years, the research both at home and abroad to sustained-controll-release fertiliser is more, particularly the coated fertilizer of coated carbamide, especially will
Rihizobium japonicum bacteroid is applied to have not yet to see report in sustained/controlled release urea coated fertilizer.

Preferably it is easy to get, reduces production cost, and substantially reduce the pollution to environment, is supplemented the nutrients to soil, improves soil texture,
Its nutrient release rate has synchronism substantially with crop regulation of fertilizer requirement.
Brief description of the drawings
Fig. 1 is the film-coated controlled release fertilizer cross-sectional view provided by the invention containing rhizobium.
Embodiment
The present invention is described in further details with reference to the accompanying drawings and detailed description.
As shown in figure 1, sustained-controll-release fertiliser provided by the invention is integrally in granular form multilayer package structure, include substantially：Fertilizer
Expect core body 11, adhesive layer 12, coated fertilizer layer 13.For mass ratio, adhesive layer 12 is the quality of fertilizer core body 11
5-9%, coated fertilizer layer 13 are the 15%-20% of the quality of fertilizer core body 11.
Specifically, fertilizer core body 11 is in spherical that can also be referred to as graininess.Adhesive layer 12 is polyvinyl alcohol material,
It is wrapped in the outer surface of fertilizer core body 11.Coated fertilizer layer 13 is the vinasse for being inoculated with rhizobium, is covered in outside adhesive layer 12
Surface.
When producing the sustained-controll-release fertiliser shown in Fig. 1, following steps are may be referred to：
Sterilized by vinasse material autoclaving, such as with high-pressure sterilizing pot.Then by carbohydrase directly with unfermentable wine
Grain is sufficiently stirred mixing, carries out ferment treatment.Preferably, the temperature of the ferment treatment is between 15-35 DEG C, and the time is between 40-48h.
Vinasse after ferment treatment are inactivated, are that 1.5 ‰ -1.8 ‰ glutaraldehydes inactivate 24h preferably with concentration.
In vinasse after rhizobium access is inactivated, and activator is added, for example, 0.17%-0.5% activator, control
Moisture is 15 DEG C -35 DEG C in 70%-85%, temperature, is fermented in the environment.
Then the vinasse after fermentation are put into the baking oven that temperature is 45-65 DEG C, powder is ground into pulverizer after drying
Shape, in case coating uses.
Spherical fertilizer core body 11 is placed in uniform rotation in rotary drum, is 7- to the spraying concentration of fertilizer core body 11 of rotation
10% poly-vinyl alcohol solution, make the surface wettability of fertilizer core body 11, form adhesive layer 12.
The vinasse added into the fertilizer core body 11 of moistening after fermentation, until poly-vinyl alcohol solution and vinasse run out,
Coated fertilizer layer 13 is formed, the dosage of poly-vinyl alcohol solution, the dosage of vinasse, last adhesive layer 12, coating material should make it that
The mass ratio of the bed of material 13 and fertilizer core body 11 meets aforementioned claim.
Take out, and dry and cool down and pack storage.
Fig. 1 is the step flow chart of preparation method embodiment provided by the invention.
In order to describe in more detail the present invention, two more specifically embodiments are provided below.
Embodiment 1 (only ferment treatment, inactivation process)：
Carbohydrase is accessed in material vinasse, cultivates 40-48h；Then enzyme-deactivating is gone out with 1.5 ‰ -1.8 ‰ glutaraldehydes
Rhizobium are accessed into 24h in material vinasse after bacterium, observe its growth result.
As a result show：Enzymatic activity is suppressed, and microorganism can be good at growth and breeding.
Embodiment 2 (only vinasse fermentation, baking operation)：
Fermented under the conditions of by vinasse and moisture be 80%, temperature is 25 DEG C -30 DEG C, activator addition is 0.33%, and
The dries pulverizing in 60 DEG C of baking ovens, by the activity of microorganism before and after thrombocytometry detection drying, concrete outcome is shown in Table 1.
Micro organism quantity contained by the material of table 1
From testing result, after drying and processing, the quantity of microorganism is：1.05 × 108/g, before about drying
85%, the bacterium number required by micro organism quantity considerably beyond microbial manure contained by it.Therefore, using this method to fermentation after
Material carry out drying and processing be feasible.
Analysis and test show that the present invention has following feature：
1st, slowly decomposed using microorganism, be cheap and easily-available, the material that environmental pollution is small, the urea of parcel is progressively released
Put, and then regulate and control Nitrogen releasing.
2nd, rihizobium japonicum thalline can degrade urea under optimum conditions, urea is existed in the form of ammonium nitrogen, easily quilt
Crop absorbs, and so as to reduce the natural loss of urea, reduces the waste of resource and the pollution of environment.
3rd, the viable bacteria body of rihizobium japonicum thalline can stimulate plant growth with secreting hormone, improve the energy and material of crop
Metabolism.
4th, the viable bacteria body of rihizobium japonicum thalline can decompose various organic matters in soil so that soil aperture is increased, and is changed
Kind soil granular structure.
To sum up, rihizobium japonicum bacteroid is applied to control release urea coated fertilizer by the present invention, passes through soybean nodulation mushroom
Thalline slowly decomposes organic coated material, and then destroys coating, the urea of parcel is progressively discharged, and then regulates and controls Nitrogen releasing,
Make coated carbamide that there is good slow/controlled release effect.In addition, rihizobium japonicum bacteroid is edaphon, so, the live body
The effect of performance edaphon can be continued after into soil.Also, the coated fertilizer for coated urea is cheap, taken
Material is extensive, greatly reduces the pollution of environment, and these reduce environmental pollution sustainable with agricultural to improving utilization of agricultural resources utilization rate
Development is respectively provided with highly important meaning.
