Abstract
The invention discloses a slow-release fertilizer special for a lotus root using biomass particle carbon as a matrix and a preparation method thereof. The particle carbon prepared by agricultural waste biomass such as corn cobs, peanut hulls, rice husks and edible fungus matrixes is the matrix material; the particle carbon is compounded with nitrogen, phosphorus, potassium and other nutrient elements which are needed by the growth of lotus roots through plurality of micropores and strong capacity of the particle carbon, so that the granular biomass carbon-based slow-release fertilizer special for the lotus root is prepared. The biomass particle carbon used by the slow-release fertilizer is black biomass particle carbon particles which are generated by incompletely burning the agricultural waste biomass under a low oxygen condition; the biomass particle carbon has a plurality of features similar to the features of soil humus, strong capacities of absorbing and maintaining nutrients and water, and good slow-release performance for nitrogen, phosphorus and potassium, and also can stimulate the growth of crops; the slow-release fertilizer prepared in such way is fertilized once, the nutrients required by lotus roots in the whole growth phase can be effectively supplied; and the slow-release fertilizer has the characteristics of increasing soil fertility, improving soil structure, efficiency, environment protection and the like, and is in favor of being large-scale popularized and applied in lotus root production.
Description
Technical field
The invention belongs to the agricultural fertilizer production technical field, particularly a kind of lotus rhizome take the biological particles charcoal as matrix is slow-release fertilizer dedicated and preparation method thereof.
Background technology
Lotus rhizome is grown under water, brings inconvenience to fertilizing management.Must plough under earth after the lotus rhizome fertilising, close to root system, be convenient to absorb after burying first, the 2nd, prevent that a large amount of nutrients is dissolved in the water, make body eutrophication, unfavorable to the lotus rhizome growth.Produce at present upper lotus rhizome fertilising except the part fertilizer, main fertilizer variety is urea, Repone K, composite fertilizer etc.These fertilizer are quick acting fertilizer, and dissolving can make soil solution concentration improve rapidly soon in a short time after the fertilising in soil, so, once can not use too many.Therefore in the breeding cycle of lotus rhizome except using base manure, also need topdress 2～3 times, repeatedly fertilising improves labour cost, cultivation benefit descends.Simultaneously, although quick acting fertilizer adopts a small amount of fertilization principle repeatedly, owing to just existing with ionic state from the rear fertilizer that is manured into soil, still make in water body and the soil nutrient density larger, easily run off and to depth of soils drip washing, cause utilization rate of fertilizer low, and contaminate environment.
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 get to a certain extent 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 lotus rhizome, prepare slow-release fertilizer dedicated method and the application of particulate biomass charcoal base lotus rhizome, can satisfy better the needs that lotus rhizome is produced.
