Abstract
The present invention relates to maifanite coated urea which is mainly composed of urea, maifanite, bone glue and starch. The present invention has the advantages that the urea bleeding and the urea volatilizing are reduced through coating the materials by the maifanite. The present invention has the advantages of slow release, long release time, low nitrate consumption, certain environmental pollution prevention effect and no soil hardening effect after the application of maifanite coated urea fertilizers. The present invention has the functions of promoting the growth, preventing the fall and the bend, strengthening roots and promoting the precocity on crops.
Description
The present invention relates to a kind of fertilizer, particularly a kind of medical stone coated carbamide.
At present, urea exists urea to run off and volatilization discharges soon, and urea amount of application utilization ratio is low, and contaminate environment does not have keying action to the farm crop growth.
The purpose of this invention is to provide a kind of medical stone coated carbamide, urea runs off and slowly-releasing has been played in volatilization by suppressing behind the medical stone coating, release period prolongs, reduce the utilization ratio that the urea amount of application improves urea, reduced nitrohydrochloric acid, environmental pollution plays a qualitative effect, fertilizer after the urea coated soil that do not harden, chessom, medical stone has facilitating effects to farm crop, and strong root is anti-to be held up.
The invention is characterized in that it comprises urea, medical stone, gelatine, starch composition, its composition is (%): urea 66%, medical stone 33%, gelatine 0.5%, starch 0.5%.
Making method of the present invention is: earlier gelatine and starch are added water furnishing tackiness agent and are sprayed on the urea, go up the medical stone stirring after, sieve again, enter the granulating disc coating, dry, sieve, check the weight, pack and get final product with electric dryer again.
Embodiment:
The rural people Zheng of the huge treasured in Gannan County chases after paddy rice with this fertilizer, topdresses experimentally with coated carbamide than coated carbamide is anti-blue or green fast in paddy rice, and than with coated carbamide is ripe not Zao, full seed, in advance precocious (5-7) sky.Impose rice yield than using not coated carbamide volume increase more than 5% with the medical stone coated carbamide.
Claims (2)
1. medical stone coated carbamide, it is made up of urea, medical stone, gelatine, starch, and its composition is (%): urea 66%, medical stone 33%, gelatine 0.5%, starch 0.5%.
2. according to the preparation method of the described medical stone coated carbamide of claim 1; it is characterized in that; described making method is as follows: earlier gelatine and starch are added water furnishing tackiness agent and be sprayed on the urea; after going up the medical stone stirring; sieve again; enter the granulating disc coating, dry, sieve, check the weight, pack and get final product with electric dryer again.
