试验分析了15℃,25℃和35℃水培条件下6种包膜控释尿素的氮素释放特性,结果表明,6种包膜控释尿素均属温度调节型控释肥料,LPcodoH10,SRcodo180,JTcodo,MScodo120,Agroum和Huda80的初期溶出(3%)天数分别为63,50,17,5,0.4和0.4 d,后期溶出(80%)天数分别为148,267,160,110,35和78 d.6种包膜控释尿素的温度依存性(Q10)在1.4～2.8之间,其中,MScodo120大于2,而SRcod0180,JTcodo和Huda80均小于2.
Study on the Nitrogen Release Characteristics of Coated Urea
The nitrogen release characteristics of 6 kinds of controlled release coated urea were studied under 15, 25 and 35℃ , using the water extraction method.The results showed that their nitrogen release characteristics were all controlled by temperature, and the 3％ solubility time of LPcodoH10, SRcodol80, JTcodo, MScodo120, Agrium and Huda80 was 63, 50, 17, 5, 0.4 and 0.4 day, and their 80％ solubility time was 148, 267, 160, 110, 35 and 7 days, respectively.Their Q10 (temperature dependency) varied from 1.4 to 2.8, Q10 of MScodo120 being ＞2, while that of SRcodo180, JTcodo and Huda80 being ＜2.
