稀土催酶尿素是我国近年来研制成功的一种高效优质的多元复合肥料。我县京原微肥厂1988年引进此项技术,通过生产试用后,1989年9月通过省级鉴定,专家们认为产品技术达到了国内同类产品的先进水平。它是根据土壤理化、生物特性的综合反应原理,以精工稀土元素作催化剂,加入自行研制的催化酶菌,促进微生物固氮菌的转化,使生物固氮与化肥中的氮素化合而成的,与其它氮素化肥相比有以下优点。
Rare earth catalyst for urea is a kind of efficient and high-quality compound fertilizer developed successfully in recent years in our country. Beijing County, the original fertilizer factory in 1988 to introduce this technology, through trial production, in September 1989 passed the provincial appraisal, experts believe that product technology has reached the advanced level of similar domestic products. It is based on the comprehensive response of soil physics and chemistry, biological characteristics of the principle of Seiko rare earth elements as a catalyst, adding their own research and development of enzyme-catalyzed bacteria, nitrogen-fixing bacteria to promote microbial transformation, biological nitrogen fixation and nitrogen in chemical fertilizers, and Compared with other nitrogen fertilizers have the following advantages.
