| 摘 要： | 试验采用15N示踪法,对不同施N水平下大豆产量及大豆的N肥利用率进行了研究。试验结果说明,在岗地白浆土上,不同施N水平的大豆产量差异显著,在一定施N水平条件下,大豆的N肥利用率随施N水平增加而提高。

| Abstract: | A pot experiment has been conducted to study the influnce of urea race on the yield and FUE(Fertilizer Utilization Efficency) of soybean.The %FVE is determined by 15 N isotope lillution method.The result showed that the %FUE is increasing with the urea rate up. The yield of soybean treated with 0 20 kg·hm 2 and 0 40kg·hm 2 urea per mu is positively sigrnificantly different from that of o kg, 0 60 kg and 0 80 kg and 12 kg.$$$$ |
