Abstract
The invention relates to a field crop nitrogen-containing top-dress fertilizer comprising sulfur-containing urea, a nitrate nitrogen fertilizer, and a trace element fertilizer. According to the invention, the sulfur-containing urea and nitrate nitrogen fertilizer are selected as nitrogen fertilizers, and the trace element fertilizer composed of calcium oxide, magnesium sulfate, zinc sulfate, ferrous sulfate, borax and manganese sulfate is used in auxiliary. All components are mixed and a granular finished product is prepared. The sulfur-containing urea can be released slowly, such that nitrogen fertilizer releasing time is prolonged, and a problem of high loss of nitrogen fertilizer of prior arts is prevented. With the various trace element fertilizer, crops can grow vigorously, and yield can be increased. The top-dress fertilizer is a sustained-release top-dress fertilizer with a good effect.
Description
Technical field
The invention belongs to nitrogenous top dressing technique
field, especially a kind of field crop is nitrogenous topdresses and preparation method thereof.
Background technology
Field crop refers to open country plantation, directly supplies with the crop of grain, oil plant and clothes raw material, mainly comprises paddy, wheat, corn, Chinese sorghum, highland barley and beans etc., and these crops and people's life is closely bound up.When crop is cultivated, first need to use enough base fertilizer large Tanaka, the fertilizer of using before sowing or transplanting, it mainly supplies with crop needed nutrient in whole vegetative period, for crop growth, creates good edaphic condition, also has the effect of improvement soil, culture fertility, except base fertilizer, different steps crop all needs to use to topdress, with meet crop in certain period a large amount of needs to nutrient, or the deficiency of supplementary base fertilizer.The nitrogen element containing in above-mentioned topdressing very easily runs off, so people are in order to guarantee the consumption of nitrogen element, must use in a large number formulation fertilizer containing nitrogen, but has caused like this waste of fertilizer, also easy contaminate environment.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, proportioning science is provided, discharges that a kind of field crop is nitrogenous slowly topdresses.
The technical scheme that the present invention takes is:
A kind of field crop is nitrogenous topdresses, and it is characterized in that: comprise the following component of proportioning by weight:
And described sulfur-containing nitrogen fertilizer is sulfur-coated urea.
And described calcareous fertilisers are calcium oxide.
And described fertiliser containing magnesium is magnesium sulfate.
And described zinc fertilizer is zinc sulfate.
And described iron fertilizer is ferrous sulfate.
And described boron fertilizer is borax.
And described manganese fertilizer is manganous sulfate.
Another object of the present invention is to provide the nitrogenous preparation method who topdresses of a kind of field crop, it is characterized in that: comprise the following steps:
(1) take sulfur-containing nitrogen fertilizer, nitrate fertilizer, calcareous fertilisers, fertiliser containing magnesium, zinc fertilizer, iron fertilizer, boron fertilizer and manganese fertilizer, standby;
(2) step component is (1) added to granulation in tablets press, make particle diameter and be the particulate state finished product of 2～4 millimeters.
Advantage of the present invention and positively effect are:
In the present invention, nitrogenous fertilizer is selected sulfur-coated urea and nitrate fertilizer, be equipped with the trace element fertilizer being formed by calcium oxide, magnesium sulfate, zinc sulfate, ferrous sulfate, borax and manganous sulfate, each component is mixed rear granulation shape finished product mutually, because sulfur-coated urea wherein can discharge slowly, extended the time that nitrogenous fertilizer discharges, there will not be a large amount of problems that run off of nitrogenous fertilizer in prior art, and various trace element fertilizers have played the effect of growing up strong and sturdy, increase output, be a kind of slow, effective topdressing that discharge.
Embodiment
Below in conjunction with embodiment, the present invention is further described, and following embodiment is illustrative, is not determinate, can not limit protection scope of the present invention with following embodiment.
A kind of field crop is nitrogenous topdresses, and innovation of the present invention is: comprise the following component of proportioning by weight:
Wherein, described sulfur-containing nitrogen fertilizer is sulfur-coated urea.Described calcareous fertilisers are calcium oxide.Described fertiliser containing magnesium is magnesium sulfate.Described zinc fertilizer is zinc sulfate.Described iron fertilizer is ferrous sulfate.Described boron fertilizer is borax.Described manganese fertilizer is manganous sulfate.
The nitrogenous preparation method who topdresses of above-mentioned field crop, comprises the following steps:
(1) take sulfur-containing nitrogen fertilizer, nitrate fertilizer, calcareous fertilisers, fertiliser containing magnesium, zinc fertilizer, iron fertilizer, boron fertilizer and manganese fertilizer, standby;
(2) step component is (1) added to granulation in tablets press, make particle diameter and be the particulate state finished product of 2～4 millimeters.
Embodiment
Choose 100 mu of lands for growing field crops, rice cultivation, wherein 50 mu are used tradition to topdress, other 50 mu are used formula of the present invention, the paddy rice of same breed is used in two groups of lands for growing field crops, according to just as management process manage, use the land for growing field crops per mu yield of the present invention's formula to improve 15%, common night, sick sickness rate was lower than 10%.
In the present invention, nitrogenous fertilizer is selected sulfur-coated urea and nitrate fertilizer, be equipped with the trace element fertilizer being formed by calcium oxide, magnesium sulfate, zinc sulfate, ferrous sulfate, borax and manganous sulfate, each component is mixed rear granulation shape finished product mutually, because sulfur-coated urea wherein can discharge slowly, extended the time that nitrogenous fertilizer discharges, there will not be a large amount of problems that run off of nitrogenous fertilizer in prior art, and various trace element fertilizers have played the effect of growing up strong and sturdy, increase output, be a kind of slow, effective topdressing that discharge.
