Abstract

The invention discloses a special coated compound fertilizer for Chinese chestnuts. The special coated compound fertilizer is characterized by being prepared from the following raw materials in parts by weight: 89-100 parts of castor seed oil cakes, 25-34 parts of sawdust, 18-24 parts of wood fiber, 28-33 parts of monoammonium phosphate, 33-40 parts of potassium chloride, 2-3 parts of magnesium sulfate, 1-2 parts of humic acid chelated manganum, 9-12 parts of nanometer bentonite, 8-11 parts of potassium of polyaspartic acid, 26-32 parts of urea, 30-36 parts of sewer mud, 28-34 parts of turfy soil, 5-7 parts of EM (Effective Microorganism) agent, 8-10 parts of soil conditioner and a proper amount of water. According to the invention, the fertilizer with a slow release effect can be prepared by fermenting organic matters, mixing the fermented organic matters and a chemical fertilizer and coating through melting by using urea; due to the addition of the soil conditioner, the special coated compound fertilizer has the effects of increasing the efficiency, promoting plants to absorb nutrients and slowing releasing; the prepared fertilizer can be used for improving the soil condition, has the characteristics of water and fertilizer retention and slow fertility loss, and can also be used for ensuring that chestnuts are robust in growth and stable in high yield.

Description

A kind of Chinese chestnut specific complex coated fertilizer and preparation method thereof

Technical field

The present invention relates to fertilizer field, particularly a kind of Chinese chestnut specific complex coated fertilizer and preparation method thereof.

Background technology

Chinese chestnut is perennial bearing-age tree, gathers in the crops every year fruit and all will take away a large amount of nutritive elements, if supplemented not in time, will certainly affect tree vigo(u)r, causes serious biennial bearing phenomenon.The rational application of fertilizer is to promote that tree body is healthy and strong, strengthens resistance and extends the result time limit, obtains one of important measures of high yield, stable yields.According to chestnut nutritional needs feature, in fertilising, to accomplish rational proportion and the split application of nitrogen phosphorus potassium, supplement the necessary middle micro-mineral nutrient of chestnut simultaneously.Base manure is generally in the fall after fruit picking, applies in the lump when ploughing deeply improvement soil, take fertilizer as main.Because now ground temperature is higher, the fertilizer applying can be is rapidly Root Absorption utilization, can strengthen the photosynthetic efficiency of blade, is conducive to recover tree vigo(u)r, accumulates more nutritive substance, for the high yield in the coming year lays the foundation.

Coated fertilizer claims again coated fertilizer, film fertilizer.The fertilizer forming with semipermeability or opacity film substrate parcel quick-acting chemical fertilizer granule.Filmogen has plastics, resin, paraffin, polyethylene and elementary sulfur etc.The object of coating is that the available nutrient of coated fertilizer the inside after being manured into soil is discharged lentamente, to extend fertilizer efficiency.Rate of release is decided by coating kind, thickness, particle diameter, fertilizer solvability, the soil moisture, soil moisture content and soil microbial activities etc.Be applicable to that economic worth is high, breeding time is long, fertilizer requirement is large but the crop of inconvenient split application, and nutrient is easy to that the temperature of leaching loss is high, area of heavy rainfull or irrigation region, especially on the light sand loam soil of quality.Existing coated fertilizer lacks specific aim more.

Summary of the invention

The object of this invention is to provide a kind of Chinese chestnut specific complex coated fertilizer and preparation method thereof.

In order to realize object of the present invention, the present invention passes through following scheme implementation:

A Chinese chestnut specific complex coated fertilizer, is made by the raw material of following weight part: castor-oil plant oil cake 89-100, wood chip 25-34, xylon 18-24, monoammonium phosphate 28-33, Repone K 33-40, magnesium sulfate 2-3, humic acid chelating manganese 1-2, nano-bentonite 9-12, poly-aspartic potassium 8-11, urea 26-32, cloaca mud 30-36, turfy soil 28-34, EM microbial inoculum 5-7, soil improvement agent 8-10, water are appropriate;

Described soil improvement agent is made by the raw material of following weight part: bamboo charcoal 10-20, nano-carbon powder 1-2, Starso 4-5, methyl methacrylate 17-19, selenium enriched yeast 3-4, copper sulfate 2-3, Zinc Gluconate 2-3, magnesium chloride 1-2, ammonium molybdate 2-3, boric acid 1-2, double pentaerythritol methacrylate 4-6, vinegar 30-40, chitosan 2-3, Oil of Eucalyptus 1-2, citric acid 2-3, nano titanium oxide 1-2, ammonium persulphate 2-3, Union carbide A-162 1-2; First preparation method forms mixture by methyl methacrylate, double pentaerythritol methacrylate and bamboo charcoal, nano-carbon powder, Oil of Eucalyptus, nano titanium oxide, ammonium persulphate, Union carbide A-162 mixing and stirring; Again all the other remaining components are mixed, fully stir and form vinegar solution; Mixture is mixed to high speed dispersion form slurry and get final product with vinegar solution.

A kind of Chinese chestnut specific complex coated fertilizer of the present invention, by following concrete steps, made:

(1) after monoammonium phosphate, Repone K, magnesium sulfate, humic acid chelating manganese, nano-bentonite, poly-aspartic potassium are mixed, add appropriate warm water, mix and add soil improvement agent, continue to stir, obtain after slurry concentrate drying, granulation;

(2) all the other remaining components except urea are mixed, keep water content 40-45%, stir, sealing, carries out anaerobic fermentation 25-30 days under normal temperature, during every turning in 3-5 days once, by drying materials ferment, pulverizing, granulation;

(3) particle in particle in urea melting and step (1) and step (2) is mixed, cooling and get final product.

The invention has the beneficial effects as follows: the present invention, by mixing with chemical fertilizer after organic substance fermentation, adopts the form of urea melting coating, makes the fertilizer with slow releasing function, adds soil improvement agent to there is synergy, promote plant to absorb the effect of nutrition, slowly-releasing; The fertilizer of making can improve edaphic condition, has preserve moisture and fertility, the fertility feature slowly that runs off, and chestnut robust growth, high yield is stable.
