A new type of coating material and solvent were developed. The evaluation of CRFs on turfgrass was involved in this work. The fluidized bed (STREA-1~(TM) Aeromatic-Fielder AG, Switzerland) was employed to produce CAU-controlled release fertilizers.

• 同时,利用从国外引进的先进包膜设备一流化仪(STREA-1~(TM),生产厂家瑞士Aeromatice-Fielder AG),在CAU51系列包膜控释肥的基础上,通过包膜溶液的加热试验和包膜配方的改进,共得到包膜控释肥(CAU61系列)98份,并对其养分释放速率进行了综合评价。
