Abstract
The invention discloses a special slow release fertilizer used for roses and taking biomass carbon particles as substrate and a preparation method of the special slow release fertilizer. Carbon particles prepared from corncob, peanut shells, rice husk, edible fungi substrate and other agricultural waste biomass are taken as the substrate material; a microporous property and strong adsorbability of the substrate material are utilized; the substrate material is compounded with nitrogen, phosphorus, kalium and other nutrient elements required for growth and development of roses so as to be made into granular biomass carbon slow release fertilizer special for roses. The biomass carbon particles used in the fertilizer are black biomass carbon particles formed after uncompleted combustion of agricultural waste biomass under the hypoxia condition, have various characteristics like soil humus, have very strong capabilities of adsorbing and keeping nutrient and water, can stimulate growth of crops, and have good performance in slow release of nitrogen, phosphorus and kalium. T therefore, after the prepared slow release fertilizer is used once, the requirements on nutrient of the whole growing period of roses can be met effectively, and the slow release fertilizer has the characteristics of increasing soil productivity, improving the soil structure, being efficient and environment-friendly and the like, and is favorable for large scale popularization and application in production of roses.
Description
Technical field
The invention belongs to the agricultural fertilizer production technical field, particularly a kind of rose take the biological particles charcoal as matrix is slow-release fertilizer dedicated and preparation method thereof.
Background technology
The rose well developed root system, fast growth, flower production is high, thus quite large to the nutrient demand amount in the soil, and rose is various to the demand of nutrient, only has different sorts nutrient reasonable coordination, just can make fresh flower high-quality, high yield, and score consecutive bumper harvests.Nitrogenous fertilizer is the important nutrition nutrient of rose demand, and nourishing and growing of rose played an important role with flower production.Only in the well-off situation of nitrogenous fertilizer, ability is flourishing, and growth is normal.If nitrogenous fertilizer is not enough, can make rose branch thin and weak, yellow leaf, shoot growth is slow.Phosphate fertilizer can promote the rose root growth, makes well developed root system, and the blade face is plump, and pattern is bright-coloured.If lack phosphate fertilizer in the soil, then can make branch weak, flower is sagging and unable.Potash fertilizer can impel the growth of rose young sprout tender leaf normal, and fresh flower quantity is increased, and bud is full, and it is high that fresh flower contains the rose oil composition.Rose must repeatedly be applied fertilizer in 1 year to use quick acting fertilizer as main at present, and its consequence one is frequently to apply fertilizer at growing period to injure a large amount of root systems, and is unfavorable to the rose Absorbing Nutrients; The 2nd, increase flower-grower's labor capacity descends cultivation benefit; Moreover fertilizer can not execute in the main rhizosphere of rose, causes utilization rate of fertilizer low.
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 rose, prepare slow-release fertilizer dedicated method and the application of particulate biomass charcoal base rose, can satisfy better the needs that rose produces.
