摘要
试验研究了3个不同施氮水平对10个玉米品种产量的影响,结果表明:桂单0810、桂单901、亚航670、桂先365及万川1306获得高产的最佳施氮量为纯N 345 kg/hm2;桂单1125及亚航671获得高产的最佳施氮量为纯N 138 kg/hm2;桂单162、亚航0919、兆丰588低氮高氮条件下产量相当,稳产性能好。
The test study on the effects of 3 different N-fertilizer levels on yield of 10 maize varieties which were selected and promoted on the production. The results showed that,to Guidan 0810, Guidan 901, Yahang 670, Guixian 365 and Wanchuan 1306,the best N application to obtain high yield was 345 kg/hm2, to Guidan 1125 and Yahang 671, the best N application to obtain high yield was 138 kg/hm2, Guidan 162, Yahang 0919, Zhaofeng 588 had the same yield in low nitrogen and high nitrogen level ,which had good yield stability.
