Abstract
The invention relates to controlled-release type blended fertilizer. The controlled-release type blended fertilizer is prepared from the following raw materials in parts by weight: 7-17 parts of sulfur-coated controlled-release urea, 7-17 parts of peptide controlled-release urea, 1 part of an urease inhibitor, and 65-85 parts of common fertilizer, wherein the nitrogen content of the sulfur-coated controlled-release urea is 34-37%, the nitrogen content of the peptide controlled-release urea is 46%, and the common fertilizer is a mixture of two or more of monoammonium phosphate, diammonium phosphate, potassium sulfate, potassium chloride, large-granule urea and organic fertilizer. By using the sulfur-coated controlled-release urea to replace partial large-granule urea blended in fertilizer, nutrient loss caused by too fast release of common urea is prevented, and thus the fertilizer usage amount is reduced, and the economic benefit is improved.
Description
Technical field
The present invention relates to a kind of agricultural fertilizer material, more specifically say a kind of slow release type bulk blended fertilizer.
Background technology
China is large agricultural country, peasant's quantity more than ten hundred million, and the area that can till the land is limited, and people more and more pay attention to the utilization ratio in soil.Add the attention of central authorities to agriculture-countryside-farmer in recent years, make the development of China's farming technology, vast farmers has also proposed new requirement to chemical fertilizer, and the utilization ratio that applies fertilizers scientifically, conveniently applies fertilizer, improves fertilizer becomes the problem that current peasant extremely pays close attention to.Due in use leakage especially severe of common chemical fertilizer, novel sustained and controlled release chemical fertilizer has become the developing direction of world today's chemical fertilizer.
The at present fertile composite fertilizer of fertilizer or the end used, the later stage imposes the ends such as urea and adds the mode of chasing after, Bulk Blending Fertilizer (BB fertilizer) single fertilization that also useful granular urea does, the later stage no longer topdresses, and peasant cries one to bombard.Add fertilizing type with base fertilizer, while topdressing, in case of the chemical fertilizer that rains evaporates in a large number, chemical fertilizer as excessive in rainwater runs off immediately, utilization ratio is extremely low, also wastes very much a large amount of manpower and materials, the necessary deep fertilizer spraying of the Bulk Blending Fertilizer of making of granular urea (BB fertilizer) single fertilization, because be easy to burn root, burn seed.Sandy soil ground, the excessive later stage of hillside fields or rainwater is seriously de-fertile, must topdress, and affects output, the soil degeneration of also can hardening.
Summary of the invention
The object of the invention is to provide a kind of nutrient equilibrium, single fertilization need not topdress, can prevent that urea from discharging too fast and causing nutrient loss, can reduce the slow release type bulk blended fertilizer of applying quantity of chemical fertilizer.
The object of the present invention is achieved like this:
This slow release type bulk blended fertilizer, made by the raw material of following weight parts:
7-17 parts, sulphur coated slow release urea;
7-17 parts of polypeptide slow-release carbamides;
1 part of urease inhibitor;
65-85 parts of common chemical fertilizer.
Optimum weight part of described raw material is:
9-13 parts, sulphur coated slow release urea;
9-13 parts of polypeptide slow-release carbamides;
1 part of urease inhibitor;
73-81 parts of common chemical fertilizer.
Described sulphur coated slow release urea nitrogen content is 34-37%.
Described polypeptide slow-release carbamide nitrogen content is 46%.
Described common fertilizer is 2 kinds or mixture of more than two kinds in monoammonium phosphate, diammonium phosphate, potassium sulfate, Repone K, granular urea, fertilizer.
This fertilizer has the following advantages:
1, the present invention replaces the granular urea in part bulk blended fertilizer with sulphur dressing sustained/controlled release urea, has prevented that common urea from discharging nutrient loss too fast and that cause, can reduce like this fertilizer amount, increases economic efficiency.
2. the present invention replaces remaining granular urea in residue bulk blended fertilizer with polypeptide slow-release carbamide, has prevented from, because common urea discharges the too fast nutrient loss causing, can further having reduced the consumption of chemical fertilizer.
3. because adding quantitative urease inhibitor in common Bulk Blending Fertilizer, the present invention effectively suppressed the water decomposition of blood urea nitrogen nutrient.
4. the present invention can make full use of sulphur dressing slow (control) and release urea, polypeptide slow-release carbamide, and urease inhibitor, common fertilizer, has mutual coordinative role between dissimilar nutrient, has guaranteed the nutrient stable market supply of crop from seedling stage to ripening stage.Increase crop yield, reduced again cost.
5. the present invention is containing common granular urea, and any soil (running fertile sandy soil ground, hillside fields of metalling run out) can single fertilization, and the later stage of need not topdressing is de-fertile, realizes the object of increasing both production and income because the application's chemical fertilizer can make to run fertile hillside fields, sandy soil ground of metalling run out.
Embodiment
The raw material that slow release type bulk blended fertilizer of the present invention is divided by following weight forms, 7-17 parts, sulphur coated slow release urea, 7-17 parts of polypeptide slow-release carbamides, 1 part of urease inhibitor, 65-85 parts of common chemical fertilizer.The optimum weight component of described raw material is, 9-13 parts, sulphur coated slow release urea; 9-13 parts of polypeptide slow-release carbamides; 1 part of urease inhibitor; 73-81 parts of common chemical fertilizer.The better components by weight percent of described raw material is, 10 parts, sulphur coated slow release urea; 11 parts of polypeptide slow-release carbamides; 1 part of urease inhibitor; 78 parts of common chemical fertilizer.Described sulphur coated slow release urea is the qualified product that can buy on market, and nitrogen content is 34-37%.Described polypeptide slow-release carbamide is the qualified product that can buy on market, and nitrogen content is 46%.Described common fertilizer is 2 kinds or mixture of more than two kinds in monoammonium phosphate, diammonium phosphate, potassium sulfate, Repone K, granular urea, fertilizer.Above-mentioned all raw materials are particulate state, and preparation method obtains fertilizer of the present invention by all raw materials by the even mixing of corresponding proportion.
