| 摘 要： | 目的]研究控释尿素对春小麦不同生育期硝酸还原酶活性和叶绿素含量的影响。方法]采用盆栽试验,以自制的3种控释尿素（CRU1、CRU2和CRU3）和普通尿素为氮源处理,测定了各处理小麦不同生育期的硝酸还原酶活性和叶绿素含量。结果]控释尿素能提高春小麦各生育期的硝酸还原酶活性,其中CRU3对硝酸还原酶活性影响显著;控释尿素提高了植株各生育期的叶绿素含量。结论]CRU3为小麦品种克98R-813的最佳氮源。

| Abstract: | Objective] The aim was to study the effects of controlled release urea on the nitrate reductase activity and the content of chlorophyll of spring wheat.Method] In the study,pot culture was carried out to determine nitrate reductase activities and the content of chlorophyll during different growth periods by using three kinds of controlled release urea(CRU1,CRU2 and CRU3) and common urea as nitrogen.Result] The results showed that in treatments using controlled urea NRA were higher than those treatments using commom urea,CRU3 was the best.The controlled urea can increase the content of chlorophyll of spring wheat.Conclusion] CRU3 was the best nitrogen for the kind of spring wheat Ke 98R-813. |
