Abstract
Chinese medicinal stone coated urea consists of urea, Chinese medicinal stone, bone glue, and starch. Coating with Chinese medicinal stone can reduce urea less through flowing and evaporation, prolong relieving period, reduce nitrate and protect environment. The coated urea produces no soil hardening and can promote growth of crops, including resisting loading, strengthening root and promoting maturing.
Description
The present invention relates to a kind of fertilizer, particularly relate to 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 nitrate, 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, the tablets press coating is coiled in the garden that enters, and is drying with electric dryer, sieves, checks the weight, is packing and get final product.
Embodiment:
The rural people Zheng of the huge treasured in Gannan County chases after paddy rice with this fertilizer, and is anti-blue or green faster than coated carbamide with coated carbamide on the paddy rice topdressing test, and than with coated carbamide is ripe not Zao, the seed born of the same parents are full, 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, a kind of medical stone coated carbamide, it mainly by: urea, medical stone, gelatine, starch are formed, and its composition is (%): urea 66%, medical stone 33%, gelatine 0.5%, starch 0.5%.
2, medical stone coated carbamide as claimed in claim 1; it is characterized in that; described making method is as follows: earlier gelatine and starch are added water furnishing tackiness agent; be sprayed on the urea; go up medical stone and stir the back, advance behind the dish tablets press coating of garden to dry with electric dryer, sieve, check the weight, to pack and get final product after sieve.
