Abstract
A durable synergist for N fertilizer is prepared from dicyandiamide (10-30 wt.%), hydroquinone (2.5-10), trace element (25-45), rare-earth elements (0.3-1) and zeolite (35-60). Said trace elements include B, Mo and Zn for acidic soil, or B, Fe and Zn for alkaline soil. Its advantages include elongating the fertility, high utilization rate of N fertilizer, high yield of crops, low cost and less environmental pollution.
Description
The present invention relates to the agrochemical technical field, particularly a kind of nitrogenous fertilizer long-acting synergist.
Along with the fast development of China's agriculture production, the nitrogenous fertilizer contradiction that supply falls short of demand becomes increasingly conspicuous.Nitrogenous fertilizer such as urea, sulphur ammonium, ammonium chloride, bicarbonate of ammonia, after being manured into soil, since urase, the very fast decomposition of the activity of nitrification and denitrification bacterium, and except that minority was absorbed by crop, most of nitrogens also were not able to do in time to be absorbed by crop, had just volatilized and had run off totally.Because these fertilizer effectivenesses are too short, so people usually repeatedly use as topdressing.Because of many employing top applications and shallow the executing of topdressing, run off so aggravated the volatilization of nitrogenous fertilizer, also shortened fertilizer efficiency period.Generally about 35%, fertilizer efficiency period has only 35-60 days to the utilization ratio of China's nitrogenous fertilizer according to surveying and determination.Deficiencies such as therefore, it is short how to solve the fertilizer effectiveness phase, and utilization ratio is low, and nutritive ingredient is single have become the problem that presses for solution at present.
The objective of the invention is: improve at the problem that prior art exists, a kind of fertilizer efficiency that prolongs and improve nitrogenous fertilizer is provided, improve its utilization ratio, can promote crop growth, strengthen degeneration-resistantly, reduce production costs, increase economic efficiency, reduce the nitrogenous fertilizer long-acting synergist of environmental pollution, and the manufacture method of this synergistic agent is provided, make it can realize suitability for industrialized production.
The present invention is achieved by following manner: a kind of nitrogenous fertilizer long-acting synergist, it is characterized in that by Dyhard RU 100, quinhydrones, trace element, rare earth, zeolite is formed, the weight percentage of 100 kilograms of these each compositions of long-acting synergist of preparation is: Dyhard RU 100 10-30, quinhydrones 2.5-10, trace element 25-45, rare earth 0.3-1, zeolite 35-60, wherein, to the acid soil trace element is boron, molybdenum, zinc, each weight percentage is followed successively by 8-15,0.3-0.5,16.7-29.5, to the alkaline soil trace element is boron, iron, zinc, each weight percentage are 8.4-12.1,1.9-3.4,16.7-29.5.
The method of the said products is characterized in that finishing through following operation:
A, raw material are accurate, and the raw material (or raw material of some caking) with above-mentioned each composition carries out grinding and sieving respectively with pulverizer;
B, mix to stir, will feed intake in the ratio of stipulating in the above-mentioned prescription, carry out closed stirring and mix, become finished product with the high-efficiency multi-function twin-shaft mixer through each raw material of A operation crushing screening;
C, quantitative package, quantitative package are 2 kilograms of every pouches, and per 25 pouches are 50 kilograms and are loaded in the sack that pouch adopts the heat seal device to seal with polyethylene plastic bag, and sack adopts stapler to sew up with woven bag and seals;
D, check warehouse-in are tested warehousing after passing with the finished product of B operation and the product of quantitative package.
1., Dyhard RU 100 has inhibiting nitrification, solidification to nitrogenous fertilizer the mechanism of action of each composition of nitrogenous fertilizer long-acting synergist of the present invention is:, we can say that it is a solidifying agent, it is again the inhibitor of nitrate reductase, mix or eutectic with nitrogenous fertilizer such as urea, sulphur ammonium, ammonium chloride, bicarbonate of ammonia with it, can increase absorption and the curing of soil colloid to ammonium ion, can slow down the nitrogen transformation of ammonia magnetic again is the reaction of nitric nitrogen, thereby reduce the leaching of nitric nitrogen and the loss that denitrification causes nitrogen, so it can prolong the fertilizer efficiency of nitrogenous fertilizer effectively, and its utilization ratio is provided; 2., quinhydrones can effectively suppress the urase activity, thereby delay the decomposition rate of urea in soil, make urea decomposition by having only 3-5 days originally, increase sharply by about 70 days and just decompose fully, reduce the volatilization and the seepage of nitrogen, prolong service time, thereby prolong the fertilizer efficiency period of urea significantly; 3., trace element (as boron, zinc, manganese, iron, molybdenum etc.) can replenish that soil lacks and the necessary trace element of crop, promotion crop absorption is the ability of other various nutritive ingredients of advocating peace with nitrogen; 4., rare earth can improve the quality of farm crop, it is the material of stimulating plant growth regulating plant physiology function, and the promotion crop growth is arranged, and improves the ability that crop is received nutritive ingredients such as nitrogen; 5., zeolite (being zeolite powder) or flyash all is porous cracks, contains the material of various trace elements, brown coal powder is rich in the acid of humic shield, not only for crop has additional nutrients, and the ability that stimulates plant growth is arranged, they are again soil improvement agents preferably simultaneously.
Nitrogenous fertilizer long-acting synergist of the present invention can be produced in nitrogen fertilizer plant after the synthesis procedure in original technical process such as urea, sulphur ammonium, bicarbonate of ammonia, add by aforementioned ratio before the evaporation prilling operation, just produce long-acting added-acting urea, long-acting added-acting sulphur ammonium and long-acting added-acting bicarbonate of ammonia.In addition, the also available manual production mode of people is prepared, promptly before fertilising, with nitrogenous fertilizer long-acting synergist of the present invention and urea, sulphur ammonium, bicarbonate of ammonia etc. in its weight (1～9): 100 ratio is puddled evenly, just can make long-acting added-acting urea, long-acting added-acting sulphur ammonium, long-acting added-acting bicarbonate of ammonia.In order to ensure the raising of these long-acting added-acting fertilizer effectivenesses, prolong its fertilizer efficiency period significantly, reach the saving of labor, economize purpose fertile, volume increase, we work out 12-15 centimetre of technology of making base manure of long-acting added-acting nitrogenous fertilizer subsoil-application by experiment again.By practice, prove again and again, the long-acting synergist that can utilize the invention described above is by proper proportion, be mixed to join various special-purpose fertile, magnetization is fertile, compound fertile in, thereby can produce special-purpose fertile, fertile, the long-acting added-acting compound fertilizer of long-acting added-acting magnetization of long-acting added-acting that does not need to impose again nitrogenous fertilizer.
The present invention compares with prior art, has following advantage: prolong and the raising fertilizer effectiveness, improve its utilization ratio, can promote crop growthing development, not have plain tasteless, non-stimulated, pollution-free, saving of labor, province's fertilizer, increasing both production and income, short early degeneration-resistant, characteristics such as disease and insect resistance, it changes the intrinsic using method of nitrogenous fertilizer in the past simultaneously, is the overlay film agricultural, water-saving agriculture is exempted to intertill agricultural comparatively ideal chemical fertilizer is provided.
