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及产量的影响。方法:采用盆栽试验,以自行研制的3种控释尿素和普通尿素为氮源,测定小麦拔节期、孕穗期、开花期、乳熟期硝酸还原酶活性和植株含氮量,成熟期测产。结果:控释尿素能提高春小麦各生育期硝酸还原酶活性,控3对硝酸还原酶活性影响显著;控释尿素能提高植株各生育期含氮量和产量。结论:各生育期硝酸还原酶活性、植株含氮量和产量结果均表明控3为此小麦品种的最佳氮源。
Objective：The aim was to study the effects of of controlled release urea on the nitrate reductase activity and yield of spring wheat.Method：In the study,pot culture was carried out to the nitrate reductase of the spring wheat in the jointing 、booting、anthesis、milky stage,the content of N and yield.we used three kinds controlled release urea 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 nitrogen and yield of spring wheat.Conclusion：The controlled urea 3 was the best nitrogen for the kind of spring wheat.
