Description
Technical field
The present invention relates to technical field of agricultural fertilizers, relate in particular to a kind of corn long-acting special formula fertilizer and preparation method thereof.
Background technology
Corn is one of world's Three major grain crops, in China, corn yield has occupied first of Three major grain crops, and this has important strategic importance to ensureing China's grain security, corn is not only important food crop, is also important feeding, medicinal and energy crop simultaneously.
Milpa is tall and big, the blade plumpness, well developed root system, its all one's life is larger to the npk nutrient demand, especially to the demand of nitrogen, nitrogen is not only the important living matters such as corn protein, chlorophyll, is also the deciding factor that affects photosynthesis of maize, corn, to the nitrogenous fertilizer sensitivity, is executed nitrogen and can be made the corn yield increasing successful.While some Meso-and micro-nutrients of Rational Application, as magnesium, sulphur, zinc, manganese, iron, boron etc. can significantly strengthen the photosynthesis of corn, further promote protein synthesis, be conducive to chasmogamy, improve the plumpness of setting percentage and seed, the resistivity of enhancing to poor environment, bring into play the yield potential of corn to greatest extent, improves corn quality.
Yet, corn will be realized high yield, must impose sufficient fertilizer in seedling stage, jointing stage, trumpet period, filling stage, and it is very inconvenient to topdress at later growth period, time-consuming effort, the cost of increasing input, and in fertilizer, the release rate of nutrient is uncontrollable, especially nitrogen very easily causes runoff, leaching, ammonia volatilization, nitrated-denitrification loss, has reduced widely the utilization ratio of fertilizer, not only waste resource, and environment is exerted heavy pressures on.In addition, because peasant for a long time drops into nitrogen phosphorus potassium excessive in farmland, caused the relative enrichment of macronutrient in soil, and the phenomenon that middle trace element lacks relatively starts to highlight, and becomes new yield and quality limiting factor.
For these problems, developed multiple envelope type slow release fertilizer both at home and abroad, although control to a certain extent the release of nutritive element, general self hard degradation of these coated fertilizers, cause soil pollution and coated fertilizer costliness price limit its extensive use.And urea formaldehyde fertilizer has been used formaldehyde as reactant owing to producing, easily cause environmental pollution and potential safety hazard.For above problem, how to prepare that a kind of nutrient is comprehensive, ratio rationally, nutritive element discharge controlled and coordinate lasting, single fertilization need not topdress, pollution-free, low-cost corn becomes relevant technologies personnel problem demanding prompt solution with agricultural fertilizer.
Summary of the invention
The present invention proposes a kind of corn long-acting special formula fertilizer and preparation method thereof, this formula fertilizer nutrient is comprehensive, ratio reasonable, the release of nutritive element is controlled and it is lasting to coordinate, single fertilization need not topdress, pollution-free and cost is lower.
A kind of corn long-acting special formula fertilizer, contain following component: 35～42 parts of peptide ureas, 5～10 parts, urea ammonium nitrogenous fertilizer, 20～30 parts of Ureaphils, 20～30 parts of potash magnesium sulphate fertilizers, 0.2～0.5 part, zinc sulfate, 0.2～0.4 part of manganous sulfate, 0.05～0.5 part, ferrous sulfate, 0.2～0.6 part of borax, 0.5～1 part of chloromethylpyridine, 0.005～0.01 part of sodium nitrophenolate, 0.5～1 part of auxiliary material by weight.
Preferably, described auxiliary material is: Tapioca Starch.
Preferably, in described corn long-acting special formula fertilizer, the mass ratio of nitrogen, phosphorus, three kinds of elements of potassium is (23～25): (8～12): (5～8), and N+P
2o
5+ K
2o>=40%.
Preferably, in described corn long-acting special formula fertilizer, the mass ratio of nitrogen, phosphorus, three kinds of elements of potassium is 24:10:6, and N+P
2o
5+ K
2o>=40 part.
Preferably, described corn long-acting special formula fertilizer, contain following component: 40～42 parts of peptide ureas, 5～6 parts, urea ammonium nitrogenous fertilizer, 20～23 parts of Ureaphils, 25～30 parts of potash magnesium sulphate fertilizers, 0.3～0.4 part, zinc sulfate, 0.25～0.3 part of manganous sulfate, 0.1～0.3 part, ferrous sulfate, 0.3～0.5 part of borax, 0.5～0.6 part of chloromethylpyridine, 0.006～0.008 part of sodium nitrophenolate, 0.7～1 part of auxiliary material by weight.
A kind of preparation method of corn long-acting special formula fertilizer comprises the following steps:
S1, once feed intake: take respectively by weight percentage potash magnesium sulphate fertilizer and Ureaphil, put into tablets press and mix, wherein, the tablets press rotating speed is 45～55r/min;
S2, peptide urea and urea ammonium nitrogenous fertilizer particle are pulverized;
S3, secondary batching: take respectively by weight percentage peptide urea, urea ammonium nitrogenous fertilizer, chloromethylpyridine and auxiliary material after described S2 pulverizes, add in tablets press, intermittent type passes into hot steam and mixes, and wherein, the tablets press rotating speed is 45～55r/min;
S4, feed intake for three times: take respectively by weight percentage zinc sulfate, manganous sulfate, ferrous sulfate, borax and sodium nitrophenolate, intermittent type adds respectively in tablets press in proportion, and intermittent type passes into hot steam and mixes, and wherein, the tablets press rotating speed is 45～55r/min;
