| 摘 要： | 以草原3号杂花苜蓿和无芒雀麦为试验材料，对两种牧草混播后当年进行刈割处理，结果表明：随刈割频率增加，两种牧草翌年返青期的株高呈减小趋势，苜蓿头茬草总产呈逐渐降低趋势，无芒雀麦呈逐渐上升趋势。刈割频率增加能够抑制苜蓿翌年叶片的光合速率，促进无芒雀麦光合速率；在初花期刈割翌年苜蓿总产量达到最高，首次刈割时期推后，翌年无芒雀麦头茬产量和光舍速率呈逐渐降低趋势，苜蓿叶片的光合速率呈增加趋势。

| Abstract: | Effects of mowing of first-year planted alfalfa and Bromus inermis mixture grassland on its growth in next year were analyzed in the study.The results showed that plant height reduced with the increasing of mowing frequence in re-green period in next year;total yield and photosynthetic rate of fisrt-stubble of alfalfa decreased while Bromus inermis increased with increasing mowing frequency;alfalfa yield up to highest in the next year when moving happened at early florescence in the first year.Yield of firs... |
