Description

A kind of improving yield of wheat compound fertilizer special and preparation method thereof
Technical field
The present invention relates to a kind of Chemical Mixed Fertilizer and preparation method thereof, particularly relate to a kind of improving yield of wheat compound fertilizer special and system thereof Preparation Method.
Background technology
In China, Semen Tritici aestivi is only second to Oryza sativa L. as a kind of main cereal crops, its cultivated area, at the big model of northern China Enclose plantation, but per mu yield and the utilization rate of fertilizer of China's Semen Tritici aestivi are the most relatively low at present, and need to carry out at whole crop cycle Repeatedly apply fertilizer, and carry out substantial amounts of field management, increase labor intensity, and China's practical situation is at present, the exhausted of kind of ground of being in Great majority are old people or women, between twenty and fifty all at immigrant laborers, the most how only can release once in the growth cycle of Semen Tritici aestivi Fertilising is the most permanently effective in growth cycle, can also improve fertilizer utilization efficiency simultaneously and ensure that the Special fertilizer for wheat of volume increase seems Particularly important.
Summary of the invention
It is an object of the invention to solve the problems referred to above, it is provided that a kind of can only release single-dose application in the growth cycle of Semen Tritici aestivi And permanently effective in growth cycle, fertilizer utilization efficiency can also be improved simultaneously and ensure the Special fertilizer for wheat of volume increase.
For achieving the above object, the technical scheme is that a kind of improving yield of wheat compound fertilizer special, it is by following weight The raw material of number is made: described improving yield of wheat composite fertilizer special is by the ammonium nitrate of nitrogen content >=34%, containing P2O5The phosphorus heavily excessively of >=46% Acid calcium, containing P2O5≥52%、K2The O potassium dihydrogen phosphate more than or equal to 34%, forms containing K2O >=11.7% potassium fulvate；Wherein nitric acid Ammonium, double superhosphate, potassium dihydrogen phosphate, the parts by weight ratio of potassium fulvate is (350-400): (12-17): 100:(60- 80).
Concrete, described Chemical Mixed Fertilizer is made up of the raw material of following parts by weight: described improving yield of wheat composite fertilizer special is by containing The ammonium nitrate of nitrogen quantity >=34%, containing P2O5The double superhosphate of >=46%, containing P2O5≥52%、K2The O biphosphate more than or equal to 34% Potassium, forms containing K2O >=11.7% potassium fulvate；Wherein ammonium nitrate, double superhosphate, potassium dihydrogen phosphate, the weight portion of potassium fulvate Number ratio is (360-390): (13-16): 100:(65-75).
More specifically, described Chemical Mixed Fertilizer is made up of the raw material of following parts by weight: described improving yield of wheat composite fertilizer special By the ammonium nitrate of nitrogen content >=34%, containing P2O5The double superhosphate of >=46%, containing P2O5≥52%、K2The O phosphoric acid more than or equal to 34% Potassium dihydrogen, forms containing K2O >=11.7% potassium fulvate；Wherein ammonium nitrate, double superhosphate, potassium dihydrogen phosphate, the weight of potassium fulvate Amount number ratio is 370:15:100:70.
Present invention also offers a kind of method preparing above-mentioned Chemical Mixed Fertilizer, comprise the steps:
(1) prepared by core material, 350-400 part ammonium nitrate, 12-17 part double superhosphate, 100 parts of potassium dihydrogen phosphates is mixed, High-tower granulation is used to prepare Chemical Mixed Fertilizer core material, by the size controlling of core material at 2.5 ~ 3.5mm；
(2) preparation of potassium fulvate solution, the potassium fulvate taking 60-80 part is dissolved in 20 ~ 40 parts of water, stirs standby；
(3) prepared by peplos agent, takes 5-10 part paraffin and is dissolved in above-mentioned potassium fulvate solution, and adds 30-50 part polyhydric alcohol, 2-3 Part hexamethyl tetramine, 3-5 part acrylate, 3-5 part water-soluble resin mixes, and stirs, and is heated to 50-60 DEG C of guarantor Temperature；
(4) peplos, peplos agent prepared by core material step (1) prepared and step (3) carries out peplos, peplos temperature through peplos agent Degree is at 50 ~ 60 degrees Celsius；Need during peplos to control the speed that peplos agent is sprayed, the most unsuitable fast, if not making through peplos agent It is finished and core material can be carried out multi-coated, until peplos agent makes to be finished；
(5) cooling, is dried peplos fertilizer after complete and is cooled to 30-35 DEG C, packs envelope.
Fertilizer employed in the present invention is acidic fertilizier, owing to double superhosphate belongs to acidic fertilizier, and itself and alkalescence Fertilizer or the mixed easily generation of carbamide
The beneficial effects of the present invention is: (1) uses double superhosphate, ammonium nitrate, potassium dihydrogen phosphate fertile as core material, and it all belongs to In acidic fertilizier, reaction will not be produced each other and reduce fertilizer efficiency, and the phosphorus content of double superhosphate is high, can reduce fertilising Amount；(2) fertilizer owing to being used by invention is acidic fertilizier, and acidic fertilizier can improve the character of soil, makes soil be more suitable for The growth of plant；(3) present invention is by using peplos agent that fertilizer core material is carried out peplos, makes the fertilizer in core material slowly discharge, And the membrane wrapping thickness of the present invention is relatively thick, and in peplos agent, add potassium fulvate, make potassium fulvate be dissolved in peplos agent And be sprayed at core material surface together with peplos agent and carry out, in fertilizer is sprinkled upon wheatland, the peplos agent of fertilizer surface is melted slowly Falling, during gradually melting away, potassium fulvate is also discharged into field slowly with peplos agent and supplies Semen Tritici aestivi absorption, especially at Semen Tritici aestivi In the stage of long Seedling, in potassium fulvate, substantial amounts of organic matter and suitable nitrogen, phosphorus, potassium content can meet the demand of Caulis et Folium Tritici aestivi；(4) exist The middle and late stage in wheat growth cycle, treats that peplos agent melts away thoroughly, and the mixing fertilizer in core material is discharged in soil and absorbs for Semen Tritici aestivi, Meet the growth demand in Semen Tritici aestivi later stage；(5) in core material of the present invention, the nitrogen of fertilizer, phosphorus, the ratio of potassium control 26%, and 18%, 7% is attached Closely, the demand in Semen Tritici aestivi later stage can be met, the Semen Tritici aestivi resistance to pest and disease damage can also be strengthened simultaneously；(6) present invention is by using relatively Thick finer and close thin layer, makes fertilizer release slowly, improves the plant absorbance to fertilizer, can realize a cycle fertilising simultaneously Once, reduce peasant's labor intensity, reduce fertilizer cost, increase the yield of Semen Tritici aestivi simultaneously.
