| 摘 要： | 朝鲜碱茅在分蘖期、拔节期和孕穗期施氮肥试验结果表明,各不同施肥时期种子和干草产量之间有极显著差异,拔节期施氮肥增产效果最好。种植第四年的朝鲜碱茅,施N138.00kg/hm2,种子和干草产量分别为482.00kg/hm2和6606.67kg/hm2,分别比对照增产193.31%和227.12%,施肥并可增加经济效益。

| Abstract: | The effects of nitrogen application on seed and herbage yield of Puccinellia chinampoensis Ohwi in tillering,jointing and booting stage were studied in the paper.The results showed that there were prominent differences in different stage of nitrogen application between seed and herbage yield,and the effects of applying nitrogen was best in tillering stage.Seed and herbage yield of this treatment(138.00kg/hm2) in fourth year were 482.00 kg/hm2 and 6606.67kg/hm2,with an increase of 193.31% and 227.12% compared to the CK,and improved economy benefits. |
