Abstract
The invention discloses a pickle prolonged-effect-time compound fertilizer and a preparation method thereof. The pickle prolonged-effect-time compound fertilizer includes nitrogen fertilizer, phosphate fertilizer, potash fertilizer, urease inhibitor, nitrification inhibitor and fertilizer synergist, wherein the total mass fraction of the nitrogen fertilizer, the phosphate fertilizer and the potash fertilizer is not lower than 96%; the preparation method of the pickle prolonged-effect-time compound fertilizer includes the steps as follows: smashing urea to powder so as to btain urea powder; adding water for fully dissolving borax, thiourea, dicyandiamide and polyaspartic acid to obtain a mixed solution; spraying all the mixed solution into the urea powder and then mixing with calcium superphosphate and potassium chloride to obtain a mixture; adding a binder; and granulating the mixture and then drying so as to obtain products. The pickle prolonged-effect-time compound fertilizer has high utilization rate, long fertilizer effect time, using safety and lower relative cost, can meet primary fertilizer application of the pickle, and can obviously reduce the convent of nitrate in the pickle.
Description
Technical field
The present invention relates to a kind of hot pickled mustard tube durable composite fertilizer, particularly relate to and a kind ofly can realize single fertilization and can reduce hot pickled mustard tube durable composite fertilizer of hot pickled mustard tube nitrate content and preparation method thereof.
Background technology
At present, durable composite fertilizer is to add the composite fertilizer that control-released agent is produced by film-coating technique or in common composite fertilizer, and its advantage is that fertilizer efficiency period is long, the plant recovery of nutrient height; Its shortcoming is the film-coating technique complex manufacturing, and residual big, practical application is few.On the other hand, add control-released agent and do not change compound fertilizer production technology, controlled-release effect is good, once base is executed, and research is relative more with application, but there are several problems in present controlled-release compound fertilizer, the one, the production cost height, as the composite fertilizer that produces with normal-butyl thiophosphoryl triamine, price is several times in a urea, and big face is applied difficulty; The 2nd, toxic side effect is big, and such as quinhydrones, people and animals eat 5 g, can cause death, and should not use; The 3rd, Different Crop is inhaled fertile rule difference, and differently the region soil characteristic is variant, and a kind of controlled release fertilizer can not accomplish to be fit to all crops, all regions uses.
Therefore, a kind of hot pickled mustard tube durable composite fertilizer that can realize single fertilization and can reduce the hot pickled mustard tube nitrate content arises at the historic moment.
Summary of the invention
In view of this, one of purpose of the present invention is to provide a kind of hot pickled mustard tube durable composite fertilizer, on the basis of nitrogenous fertilizer, phosphate fertilizer and potash fertilizer, select urease inhibitor, nitrification inhibitor and fertilizer synergist cheap, safe without toxic side effect for use, thereby reach the raising utilization rate of fertilizer, realize the hot pickled mustard tube single fertilization, and improve the purpose of hot pickled mustard tube quality; Described hot pickled mustard tube durable composite fertilizer comprises nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, urease inhibitor, nitrification inhibitor and fertilizer synergist; Wherein, the total mass mark of nitrogenous fertilizer, phosphate fertilizer and potash fertilizer is not less than 96%.
Further, described urease inhibitor is borax and/or thiocarbamide, and the massfraction of urease inhibitor in composite fertilizer is 0.11% ~ 0.78%;
Further, described nitrification inhibitor comprises Dyhard RU 100 and/or thiocarbamide, and the massfraction of nitrification inhibitor in composite fertilizer is 0.13% ~ 0.36%;
Further, described fertilizer synergist comprises poly aspartic acid, and the massfraction of fertilizer synergist in composite fertilizer is 0.04% ~ 0.12%;
Further, the weight ratio of N, P, K element is 1:(0.4 ~ 0.6 in described nitrogenous fertilizer, phosphate fertilizer, the potash fertilizer): (0.8 ~ 1.2);
Further, the N element comes from urea, the P element comes from calcium superphosphate, and the K element comes from Repone K.
Borax in the described hot pickled mustard tube durable composite fertilizer is effective urease inhibitor, and can slow down hydrolysis of urea is ammonium nitrogen, will be absorbed by crop gradually as microelement fertilizer simultaneously; Thiocarbamide is a kind of weak urease inhibitor, also is good nitrification inhibitor; Dyhard RU 100 is a kind of good nitrification inhibitor, and the major control ammonium nitrogen transforms to nitric nitrogen, can stop nitric nitrogen denitrification loss simultaneously; Poly aspartic acid is good fertilizer synergist, can strengthen crop to nitrogen phosphorus potassium and trace elements absorbed, promotes plant growth; Thiocarbamide, Dyhard RU 100 and poly aspartic acid gradually by biological degradation, are absorbed by crop with the ammonium nitrogen form in soil.
Described hot pickled mustard tube durable composite fertilizer plant recovery of nutrient height, fertilizer efficiency period is long, safe in utilization, relative cost is lower, can satisfy the hot pickled mustard tube single fertilization, and can obviously reduce the hot pickled mustard tube nitrate content.
Two of purpose of the present invention is to provide the preparation method of described hot pickled mustard tube durable composite fertilizer, can reach by following steps:
101: urea is ground into to Powdered, gets the urea powder;
102: add water borax, thiocarbamide, Dyhard RU 100 and poly aspartic acid all dissolved, mixed solution, mixes with calcium superphosphate and Repone K after described mixed solution all sprayed into described urea powder, must mixture;
103: add binding agent, to coating behind the described mixture pelleting, oven dry at last gets product.
Further, described binding agent is white meals earth, and the massfraction of binding agent in composite fertilizer is 4.0% ~ 4.5%.
Described preparation method's technology is simple, is easy to promote.
