Abstract
The invention discloses a special controlled release fertilizer for lawns and a production process thereof. The special controlled release fertilizer comprises the following components in percentage by weight: 22-28 percent of N, 8-12 percent of P, 2-6 percent of K, 2-8 percent of medium trace elements, and the balance of inevitable impurities; and the production process comprises the following steps of: uniformly mixing various weighed raw materials in a blender mixer, putting the mixed raw materials into a granulator to granulate to obtain materials with certain granularity, drying, cooling and sieving the materials to obtain qualified granules, and then carrying out film-coating, metering and packaging on the qualified granules to obtain the finished product, namely the special controlled release fertilizer, wherein unqualified granules return to the system. The special controlled release fertilizer contains a large number of elements, namely N, P and K as well as the medium trace elements and inevitable impurities and has the advantages of improving the lawn quality, maintaining the lawn durability, timely replenishing supply of nutrients to lawn soil and ensuring that the lawn quality is kept at a higher level; the release rate of available nutrients converted after the special controlled release fertilizer is applied to the soil is low, and the nutrients contained in the special controlled release fertilizer can be absorbed and utilized by crops in a delayed manner after fertilization; and in addition, the special controlled release fertilizer has longer fertilizer effect compared with a quick-acting fertilizer.
Description
Technical field
The present invention relates to a kind of fertilizer, relate in particular to the slow-release or control-release fertilizer of a kind of lawn special use; The production technique that also relates to this fertilizer.
Background technology
The lawn can purify air, and the toxic and harmfuls such as the carbonic acid gas in the absorption atmosphere, sulfurous gas, hydrogen fluoride, ammonia, chlorine discharge oxygen simultaneously; Energy dust suction sterilization; Can the Gas regulation temperature and humidity; Can reduce sound pollution; Can also the water conservation drought resisting, beautify the environment, regulate the climate.The lawn is main mainly with nourishing and growing, and is the highest to the nitrogen demand, and nitrogen easily mobile and volatilization in soil.The fertilising of initial lawn is take Agricultural Fertilizer as main, along with the lawn nutrient research deeply and the raising of soil testing technology, the Lawn management person finds that gradually the nutrient requirement of Agricultural Fertilizer and lawn growth is not too identical.On the other hand, because the lawn has the function of a series of uniquenesses, biological characteristics and cultivation management technology have determined that the lawn needs long-term uniformly nutrient supply.Use readily avaiable fertilizer and following problem will occur: amount of application is excessively low, might be able to not satisfy the needs that lawn growth is grown, and rate of fertilizer application is low just must often use, and that is a large amount of man power and material of needs just; The too high lawn of not only can burning of amount of application, and also can make a large amount of leaching loss of nutrient by irrigating, not only cause the substantial contribution waste, but also pollute the environment.
Summary of the invention
Technical problem to be solved by this invention provides a kind of macroelement nitrogen, phosphorus, potassium and middle trace element and organic matter of containing, can improve turf quality and safeguard the lawn persistence, in time replenish nutrient supply in the lawn soil, make turf quality remain on higher level, and the rate of release that changes the plant effective state nutrient after being manured into soil into is less than Quick-dissolving fertilizer, contained nutrient can delay absorbed by crops after fertilising and utilize, and has the special-purpose slow-release or control-release fertilizer in lawn of the effect of more fleshing up than quick-acting fertilizer.
For solving the problems of the technologies described above, technical scheme of the present invention is: the special-purpose slow-release or control-release fertilizer in lawn, and the weight percent of each component is: N is that 22～28%, P is that 8～12%, K is 2～6%, and middle trace element is 2～8%, all the other are organic and inevitable impurity.
Another technical problem to be solved by this invention provides a kind of production technique of producing the special-purpose sustained-controll-release fertiliser in above-mentioned lawn.
For solving the problems of the technologies described above; the production technique of technical solution of the present invention is: after mixing in mixer through the various raw materials that comprise above-mentioned component that measure; enter granulator granulation; reach the material of certain particle size through oven dry, cooling, screening; qualified particle metering packing behind coating gets finished product, underproof particle retrieval system.
As preferred technical scheme, described raw material comprises monoammonium phosphate, vitriolate of tartar, urea, humic acids, ferrous sulfate, sal epsom and borax.
As to improvement of the technical scheme, described tablets press adopts steam granulation.
Since adopted technique scheme, the special-purpose slow-release or control-release fertilizer in lawn, the weight percent of each component is: N is that 22～28%, P is that 8～12%, K is 2～6%, and middle trace element is 2～8%, all the other are organic and inevitable impurity; After will in mixer, mixing through the various raw materials that comprise above-mentioned component of metering; enter granulator granulation; reach the material of certain particle size through oven dry, cooling, screening, qualified particle metering packing behind coating gets finished product, underproof particle retrieval system.Nitrogen, phosphorus, potassium nutrition in the special-purpose slow-release or control-release fertilizer in described lawn can all dissolve, and are beneficial to the lawn absorption and give full play to fertilizer efficiency.Wherein: phosphorus all is available phosphorus, can replenish rapidly the phosphorus nutrition on lawn, promotes the lawn root growth, strengthens the lawn to the patience of arid, cold and high temperature; Water-soluble potassium and slowly available potassium organically combine, and can replenish the lawn to the demand of potassium rapidly, for a long time, can improve the resistance on lawn, such as prevention waterlogging, drought resisting, resist disease, insect pest etc.The special-purpose slow-release or control-release fertilizer in simultaneously described lawn contains the necessary element of lawn growth, can promote chlorophyllous synthesizing, and can make turf color turn green rapidly, and do not overgrow after the use, and turf color is more healthy, and can improve the anti-trample on lawn.The special-purpose slow-release or control-release fertilizer stability in described lawn is high, though fertilizer through the transportation of long period, deposit also and can not change, fertilizer efficiency is also unaffected.The present invention is the special-purpose slow-release or control-release fertilizer in lawn, sustained-controll-release fertiliser refers to various regulatory mechanisms nutrient be discharged, and consistent with the rule of Crop nutrient according to the release mode of setting, the core content that discharges not only refers to the release period of fertilizer, and the rate of release that more highlights the nutrient in the fertilizer is consistent with the crop regulation of fertilizer requirement.The present invention contains macroelement nitrogen, phosphorus, potassium and middle trace element and organic matter, be convenient to storage, transport and use, can improve turf quality and safeguard the lawn persistence, in time replenish nutrient supply in the lawn soil, make turf quality remain on higher level, and the rate of release that changes the plant effective state nutrient after being manured into soil into is less than Quick-dissolving fertilizer, and contained nutrient can delay absorbed by crops after fertilising and utilize, and has the effect of more fleshing up than quick-acting fertilizer.
