| 摘 要： | 采用水浸法、土柱淋溶法和盆栽方法研究了变性淀粉包裹型尿素氮素释放特性及生物学效应.结果表明:水浸和土柱淋溶试验中,FCU与RCU-J、RCU-C氮素释放差别很大,而RCU-J和RCU-C氮素释放具有相似性,并且与在水中相比,FCU在土壤中氮素释放速率明显降低,氮素释放曲线变化较大.苗期的玉米盆栽试验中,过量、适宜水分条...

| Abstract: | Water dissolution rate method,soil column leaching method and pot experiment were used to study the nitrogen release and biological effect of Urea which coated by modified starch.The results showed that:during the water dissolution rate method and soil column leaching method,the nitrogen release of FCU had many differences with the RCU-J and RCU-C,but the nitrogen release of RCU-J and RCU-C was similar,and compared with in water,the nitrogen release rate of FCU in soil reduced significantly,and the releasin... |
