摘　　要：本试验以中糯1号、中糯2号和京科糯2000 3个糯玉米品种为试验材料,开展了摘穗后秸秆不同收获时间对其营养成分含量和DMD影响的研究。结果显示,随摘穗后时间延长,秸秆的NDF和ADF含量都逐渐减少,而WSC含量则都逐渐增多,DMD都逐步提高;而且,总糖含量也显示增加、ADL含量也显示减少的基本趋势。可见,糯玉米摘穗后收获秸秆的间隔时间越长,秸秆的营养价值越高。In this study,the Zhongnuo No.1,Zhongnuo No.2,and Jingkenuo 2000 were used as experimental materials to investigate the influence of harvesting time on the nutritional components and DMD of waxy corn stalks after earing.The results showed that with the extension of time after stripping,the contents of NDF and ADF of the waxy corn stalks decreased,the content of WSC increased,and DMD increased.Moreover,the content of total sugars of the waxy corn stalks increased and the content of ADL decreased.Obviously,the nutritive value of waxy corn stalks increased with the extension of time after earing.
