“涂层尿素应用技术与开发研究”是广州氮肥厂委托中国科学院石家庄农业现代化研究所的应用开发项目。主要任务是探索涂层尿素增产效果及其在土壤中的移动和转化规律,确定在主要农作物上的施用技术,解决涂层尿素在北方推广应用中的技术以及开发前景和经济效益问题。1990年中国科学院石家庄农业现代化所技术开发中心将涂层尿素引入北方试验,效果显著。1991年正式组建课题组进行系统研究。1992年在试验的同时,加大了开发力
“Application and Development of Coated Urea Research” is an application development project commissioned by Guangzhou Nitrogen Fertilizer Plant of Shijiazhuang Institute of Agricultural Modernization, Chinese Academy of Sciences. The main task is to explore the effect of coated urea production and its movement in the soil and transformation rules to determine the application of the main crops on the technology to address the application of coated urea in the north of the technology and development prospects and economic benefits. In 1990, the technology development center of Shijiazhuang Agricultural Modernization Institute of Chinese Academy of Sciences introduced the coated urea into the northern experiment, and the effect was remarkable. In 1991 formally formed a research group for systematic research. In 1992 at the same time test, increased development efforts
