The invention discloses a fertilizer special for maintaining lawns and a preparation method thereof. The method comprises the following steps: weighing, mixing and stirring citric acid, zinc sulphatepowder, copper sulphate powder, manganese sulphate powder, ferrous sulphate powder, borax powder, ammonium molybdate and water at a temperature of 80-90 DEG C for 40-60 minutes to prepare trace element chelate fertilizer liquid; weighing, mixing and stirring polyvinyl alcohol, cornstarch and dicyandiamide powder at a reaction temperature of 80-90 DEG C for 40-60 minutes to prepare bonding liquid;uniformly mixing the trace element chelate fertilizer liquid and the bonding liquid according to a mass ratio of 1:4 for spare; weighing, drying, crushing and screening pyrobituminous shale residue, furfural residue, calcium carbonate, magnesium sulphate, urea, diammonium phosphate and potassium sulphate by a screen of 100-120 meshes; uniformly mixing; adding the mixture to a pelletizer; and spraying the mixed liquid to granulate so as to obtain the fertilizer special for maintaining lawns. The invention has the advantages of enough nutrients, good slow release, and the like, prolongs the nutrient-supplying time and protects the biological environment.
Description
One, technical field
The invention belongs to technical field of fertilizer, be specifically related to a kind of lawn maintenance dedicated fertilizer and preparation method thereof.
Two, background technology
At present, the lawn has become the important symbol of urban afforestation, and incity, many cities original soil is all covered by turfgrass.Under normal circumstances, turfgrass will keep located growth for many years, except using when building the lawn the base fertilizer, also need topdress in the turfgrass season of growth, because turfgrass needs often to prune, fertilizer requirement is bigger.The existing fertilizer nutrient that applies is sufficient inadequately, and slow-releasing is also relatively poor simultaneously, is difficult to adapt to the long-time growth needs of turfgrass.
Oil shale (oil shale) is a kind of organic sedimentogeneous rock that contains, and it is 2,400,000,000 tons that China has verified resource.Along with resources such as world oil, Sweet natural gas are in short supply day by day, the oil shale development and use enlarge day by day, and a large amount of lime-ash of its industrial discharge are piled into the mountain, take a large amount of soils, have a strong impact on ecotope.The oil shale lime-ash contains SiO
2, organic and that plant is essential is a large amount of and micro-, be the good raw material of exploitation composite fertilizer, but do not utilized well for a long time, caused the waste of resource.
Three, summary of the invention
The purpose of this invention is to provide a kind of nutrient abundance, slow-releasing is good, can adapt to the lawn maintenance dedicated fertilizer of the long-time growth needs of turfgrass.
Another object of the present invention provides a kind of preparation method of lawn maintenance dedicated fertilizer, this method is to be main raw material with the oil shale lime-ash, not only can solve oil shale lime-ash land occupation effectively, the problem of influence ecological environment, but also avoided the waste of resource.
For achieving the above object, the technical scheme taked of the present invention is:
One, the present invention---a kind of lawn maintenance dedicated fertilizer is made by following preparation method.
Two, the present invention---a kind of preparation method of lawn maintenance dedicated fertilizer comprises the steps:
1, preparation trace element chelated fertilizer feed liquid:
According to 5: 0.01: 0.01: 0.01: 0.01: 0.01: 0.01: 14.94 mass ratio takes by weighing citric acid (CIT), zinc sulphate powder, copper sulphate powder, manganese sulphate powder, ferrous sulfate powder, borax powder, ammonium molybdate powder and water respectively, above-mentioned raw materials is mixed, and under 80-90 ℃ temperature of reaction, stirred 40-60 minute with 100 rev/mins rotating speeds, it is stand-by to make the trace element chelated fertilizer feed liquid;
2, preparation binding liquid:
Mass ratio difference weighing polyvinyl alcohol (PVA), W-Gum, Dyhard RU 100 pulvis and water according to 5-10: 5-10: 0.1-0.2: 59.8-69.9, above-mentioned raw materials is mixed, and under 80-90 ℃ temperature of reaction, stirred 40-60 minute with 100 rev/mins rotating speeds, it is stand-by to make binding liquid;
3, preparation mixed solution:
With the trace element chelated fertilizer feed liquid and the binding liquid of step 1 and step 2 gained, more stand-by than uniform mixing according to 1: 4 quality;
4, preparation fertilizer:
According to 41.5-43.5: 3-5: 2: 2: 19: 12.5: 18 mass ratio took by weighing oil shale lime-ash, furfural dregs, lime carbonate, sal epsom, urea, Secondary ammonium phosphate and vitriolate of tartar respectively; above-mentioned raw materials is carried out drying, pulverizing; after crossing 100-120 purpose sieve; uniform mixing; add in the tablets press; spray into the step 3 gained mixed solution that accounts for raw materials quality 20%-30% and carry out granulation, promptly get the lawn maintenance dedicated fertilizer.
Above-mentioned polyvinyl alcohol (PVA) molecular weight model is 1300-1800.
Above-mentioned W-Gum is that grade is a 50-80 purpose conventional corn starch.
Fertilizer of the present invention be a kind of with cheap and easy to get, nontoxic, contain that turfgrass grows essential nutrient element, oil shale lime-ash with soil improvement function is a main raw material, the auxilliary compound manure that adds nutrients such as N, P, K, Ca, Mg, Cu, Zn, Fe, Mn, B, Mo.This invention compared with prior art has following advantage: 1) technology is simple, and non-chemical industry synthesis technique utilizes conventional equipment and compound technology to finish, and can directly drop into existing fertilizer plant production, has reduced the equipment input, has reduced cost.2) adopting the oil shale lime-ash is main raw material, and according to the characteristics of turfgrass growth desired nutritional, adds the nutritive element of a certain amount of proportioning, both satisfied turfgrass fast growth can improve the resistance on lawn again to the needs of nutrient, promote the balanced growth in lawn.The oil shale lime-ash can be used as the physical barriers that fertilizer nutrient discharges again, has increased the slow-releasing of fertilizer, has prolonged time for fertilizer, has satisfied the long-time growth needs of turfgrass, has improved utilization rate of fertilizer and has reduced raw materials cost, has increased economic benefit.Simultaneously, reduce cindery land seizure amount, protected ecotope, avoided the waste of resource, realized the reasonable resources utilization.3) trace element among the present invention is the chelating attitude, can prevent the ineffective treatment of trace element effectively, helps turfgrass to the trace elements absorbed utilization.4) the present invention adopts the binding agent composition biodegradable, and environmentally friendly, and starch can promote microbic activity through slaking, improves the physico-chemical property of soil.
