The invention has the advantages of comprehensive nutrients, good slow release, and the like, fully satisfies the growth needs of soybean and improves the yield and the quality of the soybean.
Description
One, technical field
The invention belongs to technical field of fertilizer, be specifically related to a kind of fertilizer special for soybeans and preparation method thereof.
Two, background technology
Soybean is the main oil crops of the Northeast; Traditional soybean fertilization is extremely unreasonable, only lay particular emphasis on using of farm manure and phosphate fertilizer, and has ignored using of nitrogen, potash fertilizer; Let alone other middle trace element fertilizer; Because using day by day of fertilizer reduces, the yield per unit of soybean is on the low side always, is generally 2250kg/hm
2, its yield potential is bigger, and it is carried out scientific and reasonable fertilising, will be the important channel of improving output.Therefore, need fertile characteristics according to soybean, it is comprehensive to develop a kind of nutrient, and slow-releasing is better, can fully satisfy soybean to nutrient demand, brings into play fertilizer effect to greatest extent, and the dedicated fertilizer that improves soybean yields and quality is particularly urgent.
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, it is fertile to add the compound that this material processes; 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 comprehensive to the purpose of this invention is to provide a kind of nutrient, and slow-releasing is better, can fully satisfy the fertilizer special for soybeans of soybean to nutrient demand.
Another object of the present invention provides a kind of preparation method of fertilizer special for soybeans; 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 realizing above-mentioned purpose, the technical scheme that the present invention takes is:
One, the present invention---a kind of fertilizer special for soybeans is made by following preparation method.
The preparation method of two, the present invention---a kind of fertilizer special for soybeans comprises the steps:
1, preparation trace element chelated fertilizer feed liquid:
According to 5: 0.01: 0.01: 0.01: 0.01: 14.96 mass ratio took by weighing Hydrocerol A (CIT), zinc sulphate powder, manganese sulphate 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 for use 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 (DCD) 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 for use 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 for use than uniform mixing according to 1: 4 quality;
4, preparation fertilizer:
According to 44.38-49.38: 5-10: 2: 3.7: 23.92: 16 mass ratio took by weighing oil shale lime-ash, 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 adds 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 soybeans.
Above-mentioned Z 150PH (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 the soybean growth essential nutrient element, oil shale lime-ash with soil improvement function is main raw material, the auxilliary compound manure that adds nutrients such as N, P, K, Ca, Mg, Mn, Zn, 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 accomplish, 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 soybeans they grow desired nutritional, adds the nutritive element of a certain amount of proportioning, has fully satisfied the soybeans they grow needs, has improved output and the quality of soybean.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; Improved utilization rate of fertilizer; Realize the single-dose application of soybeans they grow phase, reduced the fertilising frequency, saved human and material resources; Reduce 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; Helping soybean trace elements absorbed utilized 4) the present invention adopts the sticker composition biodegradable, and environmentally friendly, and contain the nitrogen fertilizer slow releasing agent Dyhard RU 100.
