Abstract
The invention discloses a slow-release fertilizer specialized for pear trees by using biological granular carbon as matrix, and a preparation method of the slow-release fertilizer, which comprises the following preparation steps: using granular carbon prepared from agricultural waste such as corncobs, peanut shells, rice husks and edible mushroom matrix as a matrix material, making use of the porous property and the strong adsorption capability of the matrix to compound with nitrogen, phosphorus, potassium and other nutrition elements necessary for the growth of the pear trees to prepare the granular biological carbon-based slow-release fertilizer specialized for the pear trees. The biological granular carbon is black biological granular carbon particles formed after incomplete combustion of the agricultural waste under a condition with low oxygen; the biological granular carbon has various properties similar to soil humus, and the capability of the slow-release fertilizer for adsorbing and retaining the nutrition and the moisture is very strong; the biological granular carbon is also capable of stimulating the growth of crops, having good performance of slowly releasing the nitrogen, the phosphorus and the potassium; the prepared slow-release fertilizer is capable of effectively supplying the nutrition demand of the pear trees in the whole growth period by one fertilization time, having the characteristics of improving the soil fertility, improving the soil structure and achieving high efficiency and environmental protection, is beneficial for large-scale popularization and application in the pear tree production.
Description
Technical field
The invention belongs to the agricultural fertilizer production technical field, particularly a kind of pear tree take the biological particles charcoal as matrix is slow-release fertilizer dedicated and preparation method thereof.
Background technology
Pear tree is perennial bearing-age tree, and annual results fruit all will be taken away a large amount of nutritive elements, if untimely being replenished will certainly affect tree vigo(u)r, causes serious biennial bearing phenomenon.Therefore, the rational application of fertilizer is to promote that pear tree tree body is healthy and strong, strengthens resistance and prolongs the as a result time limit, obtains one of important measures of high yield, stable yields.There is following problem aspect the pear tree fertilising at present: the one, in the pear tree Annual growth cycle, need repeatedly fertilising, the chemical fertilizer that current pear tree is used mainly is quick acting fertilizer, they dissolve in soil soon, if applied once too much not only injures root system, also can cause the loss of nitrogen, potash fertilizer: the 2nd, the pear tree root system is distributed in the darker soil layer, answer ditching to execute the competence exertion effect in the root district during fertilising, growing period frequently ditching fertilising can cut off a large amount of root systems again, is unfavorable for the absorption to nutrient; The 3rd, because quick acting fertilizer easily drip washing with rainfall or irrigation water in scholar's earth, so utilization rate of fertilizer is not high.
The method one that addresses these problems in fertilising at present is the consumption that increases fertilizer, the 2nd, and chemical fertilizer application is taked on a small quantity repeatedly.Along with the continuous expansion of pear tree cultivated area, fertilizer can not be satisfied the demand, and peasant's labour intensity and recruitment cost repeatedly used and increased to chemical fertilizer.Adopt the long-acting or slow special release fertilizer single fertilization of pear tree more and more to be subject to peasant's welcome.Present slow release fertilizer both domestic and external generally all is to reach the purpose that prolongs fertilizer efficiency by physical methods such as coating, parcel, packing, coatings, such as the coated fertilizer of bag Thio Urea, polymer coated fertilizer, fertilizer bag fertilizer, coated fertilizer and with Quick-dissolving fertilizer and the mixing formed Wrapped fertilizer of rubber latex etc.The slow controlled-release technology that also has employing physics and biochemical method to combine is produced slow release fertilizer.The general cost of these fertilizer is higher, and seldom possesses hole and adsorptive power, more without increasing soil fertility, improving the characteristics such as Soil structure.
On the other hand, at present China has become one of country of agriculture waste biomass generation maximum in the world, it is reported, the gross annual output of all kinds of agricultural crop straws of China amount of giving birth to reaches more than 700,000,000 tons, wherein straw is 2.3 hundred million tons, 2.7 hundred million tons of maize straws, 100,000,000 tons of peanut, beans and autumn coarse cereals stalks.The easiest way of Treating straw is directly to burn down on the farm at present.Burning season, once repeatedly occuring to be forced to close event because smog all over the sky causes flight to land with motorway, both wasting a large amount of precious resources, bringing severe contamination to environment again.Therefore agriculture waste biomass outlet has become a great problem that solution is badly in need of in government department.Particularly along with the raising of level of agricultural production development and life of farmers level, fewer and feweri to utilizing of original agriculture waste biomass as fuel and fertilizer, agricultural wastes are more and more.
Summary of the invention
The purpose of this invention is to provide a kind of take the standby particle charcoal of the agriculture waste biomass-makings such as corn cob, Pericarppium arachidis hypogaeae, rice husk, stalk, edible fungi substrate as substrate material, utilize its many micropores, strong adsorptive power, to grow necessary nitrogen, phosphorus, potassium and other nutritive elements compound with Growth of Pear Trees, prepare slow-release fertilizer dedicated method and the application of particulate biomass charcoal base pear tree, can satisfy better the needs that pear tree produces.
For achieving the above object, the technical solution used in the present invention is as follows:
