Description
Technical field
It is specifically a kind of using Cortex walnut and dento liva as the slow-release fertilizer of raw material the present invention relates to slow release fertilizer field
Material.
Background technology
South of Gansu Province is resourceful, with a varied topography, and the big ditch depth in mountain, living resources species is various, and photo-thermal is sufficient, per capita arable land
Few, mountainous region accounts for more than 90%, and rainfall spatial and temporal distributions are uneven, and arid frequently occurs, and mud-rock flow landslide is serious, soil to fertilizer not
It can keep well, therefore have more and more urgent requirement to discharging slow release fertilizer.Traditional sulphur makees coating material can not
The problem of sealing fertiliser granulates surface well, envelope membrane surface is usually present with " pin hole " or crack, it is easy to water
Via or seam enter fertilizer core and quickly dissolve fertilizer, reduce slow release effect.And sustained release is manufactured with wood residue
The method of fertilizer casing, but this method is a compression moulding, since wood residue is solid, poor fluidity, charging and pressure
Wood residue hardly enters the bottom of mold during housing processed so that and the housing bottom suppressed is usually very thin, insufficient strength,
The housing bottom of compacting is even made cavity occur, does not load fertilizer.
The content of the invention
Present invention proposition is a kind of using Cortex walnut and dento liva as the slow release fertilizer of raw material, and Cortex walnut and dento liva is made to manufacture and delay
Release fertilizer.
To achieve the above object, it is of the present invention a kind of using Cortex walnut and dento liva as the slow release fertilizer of raw material, it is described slow
Release fertilizer is to be prepared from the following raw materials in parts by weight：150-200 parts of dento liva, 70-120 parts of walnut shell, green peel of walnut 70-
120 parts, 5-10 parts of white rot bacteria agent, 40-70 parts of ammonium sulfate, 30-60 parts of dipotassium hydrogen phosphate, 9-45 parts of magnesium sulfate, vermiculite 150-
300 parts；
Preparation process is as follows：
(1) by proportioning, dento liva, walnut shell, each half of green peel of walnut and ammonium sulfate, dipotassium hydrogen phosphate, sulphur are taken
Sour magnesium, vermiculite are uniformly mixed；The moisture of mixture is adjusted as 55-65wt%, controls pH4.5-6.5, fermentation reactor system is decomposed；Temperature
Timing when rising to 50 DEG C is kept for 4-7 days；Turning, timing when temperature rises to 50 DEG C again are kept for 3-5 days, make solid culture
Base；
(2) culture medium is placed in progress high-temperature sterilization 60-70min in high-pressure sterilizing pot, temperature is in holding autoclave
121-125 DEG C, pressure 0.12-0.2Mpa；Sterilized culture medium is taken out, is placed in aseptic inoculation room and cools down；Work as culture
When base is cooled to 15-24 DEG C, white rot bacteria agent is mixed, inoculum concentration accounts for culture medium weight percent as 1-8%, control culture room temperature
It spends for 15-33 DEG C, is cultivated；
(3) stir culture medium in incubation, through 5-9 days culture after obtain covering material, by covering material be coated on through
Cross the remaining dento liva after high pressure sterilization, walnut shell, on green peel of walnut；It dries in the shade after absorption covering material.
Culture medium is stirred or stirred in the incubation, is stirred 3-6 times daily within 1-2 days；Stir 6-11 daily within 3-6 days
It is secondary；It is stirred 5-6 times daily in 7-9 days.
Taken in the step (1) dento liva, walnut shell, each half of green peel of walnut and ammonium sulfate, dipotassium hydrogen phosphate,
Magnesium sulfate, vermiculite are uniformly mixed, and dento liva, walnut shell, the powder particle diameter of green peel of walnut are 1-10mm in the step.
Culture medium is stirred in step (3) incubation, after culture in 5-9 days, addition residue is after high pressure sterilization
Dento liva, walnut shell, green peel of walnut mix thoroughly, adsorb after dry in the shade；Dento liva, walnut shell, green peel of walnut powder in the step
Particle footpath is 5-15mm.
It is described a kind of using Cortex walnut and dento liva as the slow release fertilizer of raw material, wherein step (3) described method for coating, it realizes
Step is as follows：
A, dento liva, walnut shell, green peel of walnut coarse granule of the residue after high pressure sterilization are heated to 60-100 first
It DEG C is placed in agitating device and adds in organic solvent, the weight of the organic solvent of addition is the 5-20% of the coarse granule weight；
B, the coarse granule of organic solvent and covering material example 1 in mass ratio will be added in：1 dries in the shade after mixing；It again will be surplus
Remaining covering material is uniformly mixed again with being uniformly mixed the material to dry in the shade；
C, the coarse granule covering material of mixing again is mixed with additive, the additive is by polyurethane, polypropylene, bee
Honey and modified starch composition；The polyurethane, polypropylene, the mixed weight ratio of honey and modified starch are 1：1-5:1-2:1-
8。
The coarse granule covering material and the mixed weight ratio of additive are 94-95：5-6.
The organic solvent is made of olive oil and walnut oil, and wherein the ratio of olive oil and walnut oil is 93-96：4-
7。
The white rot bacteria agent is formulated by following two microbial inoculums, and it is total that both microbial inoculums account for composite microbial fertilizer bactericide
The percentage of weight is：Whiterot fungi 70-90%；Bacillusmusilaginosiengineering 10-30%.
Of the present invention a kind of using Cortex walnut and dento liva as the slow release fertilizer of raw material, its advantage is：With walnut
Skin and dento liva remain the porosity of timber for the slow release fertilizer of raw material, and permeability is more preferable, and can control shell according to ratio
The slow release speed and effect of body；The coarse granule stability of Cortex walnut and dento liva is good, and intensity is high, this slow-release fertilizer is enable to reach longer
Slow-release time, after fertilizer is coated on coarse granule and is manured into soil, rainwater impregnates coarse granule, and the fertilizer of dissolving passes through walnut
The exudations such as the intrinsic interstitial channels of skin and dento liva, the new tunnel then generated further through adhesive degradation supply plant nutrient,
Fertilizer, which endlessly oozes out, plays the role of slow releasing function, last Cortex walnut and dento liva also can under whiterot fungi in the soil by
It decomposes, for plant nutrient；The inventive method manufacturing method is simple, easy to operate, and being capable of flexible making as needed
The Cortex walnut and dento liva of required fertilizer rate of release and size；After the housing applies fertilizer to plants such as forest, flowers, both it ensure that
Crop constantly obtains nutrient during its growth, and the nutrient that plant growth is kept to need reduces fertilizer application frequency, avoids
Fertilizer loss improves the comprehensive utilization ratio of fertilizer, and it is excessive and cause the generation of burn seedlings to also avoid single-dose application.
