Description
One, technical field
The invention belongs to technical field of fertilizer, be specifically related to a kind of fertilizer special for celery cabbages and preparation method thereof.
Two, background technology
Chinese cabbage is one of traditional vegetable variety of China, is referred to as " Chinese cabbage ".Especially in China the Northeast, also can pickle into good to eat sauerkraut, become one of main vegetables that people survive the winter.During plantation Chinese cabbage, need use common chemical fertilizer, because the slow-releasing of this kind fertilizer is relatively poor, cause the nutrient loss in the fertilizer serious, utilization rate of fertilizer is lower.In order to pursue high yield, often to topdress in a large number, to satisfy the growth needs of Chinese cabbage.So not only can cause the intravital nitrate content of Chinese cabbage to exceed standard the serious harm HUMAN HEALTH.Leaching, denitrification, volatilization loss also can take place in the nitrogen element that applies in a large number in soil, not only cause nutrient loss, also direct contaminated soil environment.In addition, because the market value of Chinese cabbage is lower, constantly topdressing needs to drop into great amount of manpower and material resources, makes that its profit is more very little.
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 plant is essential a large amount of and in, trace element, be the fertile additive of ideal compound, add the compound fertilizer that this material is made, the getting fat water conservation is arranged, promote the soil organisms vigor, characteristics such as improve the soil, but do not utilized well for a long time, caused the waste of resource.
Three, summary of the invention
It is good to the purpose of this invention is to provide a kind of slow-releasing, the fertilizer special for celery cabbages that utilization rate of fertilizer is high.
Another object of the present invention provides a kind of preparation method of fertilizer special for celery cabbages, 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 fertilizer special for celery cabbages is made by following preparation method.
The preparation method of two, the present invention---a kind of fertilizer special for celery cabbages comprises the steps:
1, preparation trace element chelated fertilizer feed liquid:
According to 6: 0.02: 0.01: 0.5: 0.2: 23.27 mass ratio took by weighing citric acid (CIT), zinc sulphate powder, Manganous chloride tetrahydrate powder, calcium chloride powder, sal epsom 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:
According to 5-10: 5-10: 0.05-0.1: 0.05-0.1: 0.01: 0.02: the mass ratio of 49.77-59.87 is weighing polyvinyl alcohol (PVA), W-Gum, Dyhard RU 100 (DCD) pulvis, quinhydrones (HQ) pulvis, ammonium molybdate powder, borax 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 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 3: 7 quality;
4, preparation fertilizer:
According to 46.4-48.4: 3-5: 2: 16.5: 13.1: 12: 5 mass ratio took by weighing oil shale lime-ash, furfural dregs, lime carbonate, urea, Secondary ammonium phosphate, vitriolate of tartar and Repone K 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 fertilizer special for celery cabbages.
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 Chinese cabbage grows essential nutrient element, oil shale lime-ash with soil improvement function is a main raw material, the auxilliary mixture compound manure that adds nutrients such as N, P, K, Ca, Cu, Zn, B.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 Chinese cabbage growth desired nutritional, adds the nutritive element of a certain amount of proportioning, has satisfied the quick growth needs of Chinese cabbage.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 improved utilization rate of fertilizer, has realized Chinese cabbage single-dose application in vegetative period, has reduced the fertilising frequency, has saved human and material resources.In human body harm of having avoided causing and soil pollution because of topdressing in a large number, also reduced raw materials cost, increased economic benefit.Cindery land seizure amount has also obtained great reduction, has protected ecotope, has avoided the waste of resource, has 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 Chinese cabbage 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, and contains nitrogen fertilizer slow releasing agent Dyhard RU 100 (DCD), quinhydrones (HQ) and micro-molybdic acid ammonium, borax.
