Abstract
The invention discloses a special slow release fertilizer for walnut by using biomass granular carbon as a matrix and a preparation method thereof. Granular carbon prepared from agricultural wastes such as corn cobs, peanut shells, rice hulls, edible fungi matrix and the like are used as a matrix material; and based on the micro-pores and strong adsorption capability of the matrix material, the granular biomass carbon-based special slow release fertilizer for the walnut is prepared by compounding the matrix material and nitrogen, phosphorus, potassium and other nutritional elements required by growth and development of the walnut. The biomass granular carbon is black biomass granular carbon granules formed after the agricultural waste biomass is incompletely burnt under the low-oxygen condition, has multiple properties similar to soil humus and strong adsorption and nutrient and moisture holding capabilities, can stimulate growth of crops, and has good slow release performance on nitrogen, phosphorus and potassium; when the prepared slow release fertilizer is applied at one time, the requirements of the walnut for nutrients in the whole growth period can be effectively met; and the slow release fertilizer has the characteristics of increasing soil fertility, improving the structure of soil, realizing high efficiency and environment friendliness and the like, and is beneficial to large-scale popularization and application in the production of the walnut.
Description
Technical field
The invention belongs to the agricultural fertilizer production technical field, particularly a kind of walnut take the biological particles charcoal as matrix is slow-release fertilizer dedicated and preparation method thereof.
Background technology
In walnut was produced, the rational application of fertilizer was the important measures that guarantee the growth of walnut bulk-growth and reach stable high yield.Nutrient demand and the phenological period of walnut in annual cycle is closely related: after sprouting spring, the phenology process of walnut major organs is very rapid, principal feature during this is to breathe by force, growth is fast, physiological activity is vigorous, especially the nutrient that a large amount of solid plant need is more, thereby must impose quick-acting nitrogen, phosphate fertilizer before sprouting spring.5, after June, fruit Rapid development, bud begin differentiation.Whether the size of fruit development and the quality of bud differentiation and quantity depend between the consumption of nutrient and the accumulation balance.Therefore at this moment should satisfy phosphate fertilizer and potash fertilizer supply.Enter after July, fruit is the bones of the body firmly, and kernel germinates, and this moment fertilising should be take potash fertilizer as main, and be aided with a small amount of nitrogen, phosphate fertilizer.At present walnut fertilising is mainly take quick acting fertilizer as main, and these fertilizer dissolve in soil soon, and fertilizer efficiency is short, and nitrogen, potash fertilizer easily run off.Owing to directly contact with soil, phosphate fertilizer is easily by soil fixing.In order to satisfy the demand of different growth phases, Different Nutrients kind, walnut need repeatedly apply fertilizer in Annual growth cycle, this has not only increased peasant's workload and labour cost, because frequent ditching fertilising has also injured a large amount of root systems, further affects nutrition absorption and improves output.Slow release fertilizer claim again slow-release fertilizer (
Slow available fertilizers) or release and release control fertilizer (
Control release fertilizers), compound release rate in the soil control slow or that nutrient releasing speed can obtain to a certain degree that contains nutrient in its fertilizer continues to absorb for crop.Use slow release fertilizer can reduce the particularly loss of nitrogen in soil of fertilizer nutrient, improve utilization rate of fertilizer, reduce fertilising operation number of times, save labour and expense, and can alleviate the pollution that excessive fertilization causes for environment.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, compound with grow necessary nitrogen, phosphorus, potassium and other nutritive elements of walnut, prepare slow-release fertilizer dedicated method and the application of particulate biomass charcoal base walnut, can satisfy better the needs that walnut is produced.
For achieving the above object, the technical solution used in the present invention is as follows:
