Abstract
The invention discloses a polypeptide fertilizer and a preparation method thereof for wheat. The weight ratio of nitrogen, phosphorus pentoxide, potassium oxide, polyaspartic acid and zinc of pure nutrient of the polypeptide fertilizer is (20-24): (14-18): (5-8): (0.1-0.3): (0.1-0.3). The formula is reasonable and satisfies the absorption law of the wheat for nutrient. Enrichment of the nitrogen, the phosphorus pentoxide, the potassium oxide and trace elements is facilitated due to the addition of the polyaspartic acid to supply the plant, so that the plant can use the fertilizer effectively, and the utilization rate of the fertilizer is improved. According to the polypeptide fertilizer, the tower type melting technology is adopted, so that each polypeptide fertilizer grain has even nutrient, the plant can grow evenly, and the whole growth vigor is good.
Description
Technical field
The present invention relates to agriculture field, particularly Semen Tritici aestivi polypeptide fertilizer also relates to the preparation method of Semen Tritici aestivi polypeptide fertilizer.
Background technology
Wheat is the second largest food crop of China, and its growth cycle is long, uses traditional composite fertilizer at present mostly.After traditional composite fertilizer was manured into soil, most of nutrient was volatilized or is run off, so the plant recovery of nutrient of fertilizer is low, is merely about 30%.In recent years, paid attention to deeply, mainly study, but the nutrient that contains in the different soil is different from the nutrient uptake feature of crop to the research of fertilizer specially for wheat.The Plain of Huanghua Area is the main planting site of China's wheat, and soil is brown earth or drab soil, and total nitrogen content is in medium level, level such as low during rapid available phosphorus is in, and quick-acting potassium content is in the level of enriching.Be not directed against the fertilizer specially for wheat in the Plain of Huanghua Area in the market.Therefore, be badly in need of a kind of Semen Tritici aestivi polypeptide fertilizer, fully combine the soil nutrient characteristics in the Plain of Huanghua Area, can satisfy wheat, reduce the loss of fertilizer, increase operation rate nutrient absorbing rule.
Summary of the invention
In view of this, one of the object of the invention is to provide Semen Tritici aestivi polypeptide fertilizer, and its prescription rationally, and is can utilising efficiency high, can improve the output of wheat after using.
For realizing the foregoing invention purpose, technical scheme is:
Semen Tritici aestivi polypeptide fertilizer, the weight ratio of pure nutrients of nitrogen, Vanadium Pentoxide in FLAKES, potassium oxide, SAP 73 and the zinc of said polypeptide fertilizer is 19-22:13-16:5-9:0.1-0.3:0.1-0.3.
Preferably, the weight ratio of pure nutrients of nitrogen, Vanadium Pentoxide in FLAKES, potassium oxide, SAP 73 and the zinc of said polypeptide fertilizer is 22:16:5:0.2:0.2.
Preferred, the raw material of said polypeptide fertilizer is made up of for 153 parts 388 parts in urea, 364 parts of monoammonium phosphates, 84 parts in Repone K, 9 parts of Zinc Sulphate Heptahydrates, 2 parts of SAP 73s and dry powder by weight.
Preferably, the weight ratio of pure nutrients of nitrogen, Vanadium Pentoxide in FLAKES, potassium oxide, SAP 73 and the zinc of said polypeptide fertilizer is 21:13:9:0.1:0.3.
Preferred, the raw material of said polypeptide fertilizer is made up of for 164 parts 383 parts in urea, 295.5 parts of monoammonium phosphates, 150 parts in Repone K, 4.5 parts of Zinc Sulphate Heptahydrates, 3 parts of SAP 73s and dry powder by weight.
Preferably, the weight ratio of pure nutrients of nitrogen, Vanadium Pentoxide in FLAKES, potassium oxide, SAP 73 and the zinc of said polypeptide fertilizer is 19:15:9:0.3:0.1.
Preferred, the raw material of said polypeptide fertilizer is made up of for 163 parts 329 parts in urea, 341 parts of monoammonium phosphates, 150 parts in Repone K, 13 parts of Zinc Sulphate Heptahydrates, 1 part of SAP 73 and dry powder by weight.
Most preferred; The mass percent of nitrogen is 46.4% in the said urea; The mass percent of nitrogen is 11% in the said monoammonium phosphate, the mass percent of Vanadium Pentoxide in FLAKES is 44%, and the mass percent of potassium oxide is 60% in the said Repone K, and the mass percent of zinc is 23% in the said Zinc Sulphate Heptahydrate.
Two of the object of the invention is to provide the preparation method of Semen Tritici aestivi polypeptide fertilizer, and technical scheme is:
The preparation method of said Semen Tritici aestivi polypeptide fertilizer gets urea, monoammonium phosphate, Repone K, Zinc Sulphate Heptahydrate, SAP 73 and dry powder by proportioning, mixes, and sends into then and carries out granulation in the high tower pellatizer machine, gets Semen Tritici aestivi polypeptide fertilizer.
Beneficial effect of the present invention is: Semen Tritici aestivi polypeptide fertilizer disclosed by the invention, prescription rationally, in the wheat growth that takes into full account to nutrient absorbing rule and Plain of Huanghua Area soil nutrient characteristics:
The growth cycle of wheat is long, moves strategy behind the nitrogen before nitrogen adopts, and soon crop at base manure with on topdressing, reduces using of base manure nitrogenous fertilizer, according to the ratio of nitrogen in this tactful moderate reduction Semen Tritici aestivi polypeptide fertilizer to the demand assignment of nitrogenous fertilizer;
Since winter with spring temperature lower, therefore the fertilizer efficiency of phosphorus is very low, the ratio of increase Vanadium Pentoxide in FLAKES in Semen Tritici aestivi polypeptide fertilizer;
Because Plain of Huanghua Area soil potassium content is in the level of enriching, and adds the most of areas straw-returning, therefore in Semen Tritici aestivi polypeptide fertilizer, reduce the ratio of potassium oxide;
Zinc can promote that the wheat root prosperity is sturdy, and root system is pricked dark, and the drought resisting freezing tolerance strengthens, and wheat lacks zinc, the wheat seeding delay of turning green, and jointing is difficult, and plant is short and small, and blade master pulse both sides chlorosis has influence on the wheat later stage normally to be in the milk, and the threshing phenomenon occurs; Root system is undeveloped, and heading is slow, and fringe is little, and grain is few.
Semen Tritici aestivi polypeptide fertilizer disclosed by the invention fully satisfies wheat growth to nutrient demand such as macroelement nitrogen, Vanadium Pentoxide in FLAKES and potassium oxides, considers wheat growth simultaneously to the trace element zinc demand, utilizes SAP 73 that metals ion is had sequestering action; Can enriched in nitrogen; Phosphorus, potassium and trace element are supplied with plant, make plant more effectively utilize fertilizer; Improve the output of wheat, reduce pollution simultaneously environment.
Adopt tower fusion technology granulation among the present invention, every nutrient uniform distribution in the polypeptide fertilizer that has guaranteed to prepare helps promoting that crop evenly grows, and whole growing way is even.
