| 摘 要： | 在不同施氮肥量、刈割时期和留茬高度条件下,对无芒雀麦草地的生产性能进行了研究。试验表明,随施肥量的增加无芒雀麦的生产性能显著提高,在施肥量0～140 kg/hm2范围内,无芒雀麦的草产量和粗蛋白含量增加显著,140～210 kg/hm2范围内变化不明显。综合比较,处理组合A3B1C3的干草收获量最高,A3B2C3的粗蛋白收获量最高。

| Abstract: | Effect of different nitrogenous fertilizer rate,mowing period and stubble height on on the production performance of Bromus inermis was studied.Results of experiment showed that with the increase of fertilizer,smooth brome production performance improved significantly.In the treatment of fertilization of 0 to 140 kg/hm2,smooth brome grass yield and crude protein content increased obviously,but they changed little within 140 kg/hm2-210kg/hm2.Comprehensive comparison,the highest hay harvest combination is A3B1C3 and the highest level of crude protein combination is A3B2C3. |
