| 摘 要： | 以郑单958为试验材料,在抽雄期对穗上部进行不同层次的去茎叶处理,测量各处理获得的生物产量及籽粒产量。结果表明:带2叶去雄与CK相比差异显著,籽粒可增产532.5 kg.hm-2,增产显著,同时大约可获得352 kg.hm-2干物质,相当于2.84 hm2的玉米田就可生产出1 hm2羊草地提供的干物质,经济效益显著,因此带2叶去雄青贮可达到增产、增收,效益最大化的目的。

| Abstract: | Taking the cultivar Zhengdan 958 as the experiment material,remove different level stems and leaves above the ear of the plant at tasseling stage, which will be silaged, the biomass of the stems and leaves,and the grain yield of each treatment mere measured. The results showed that the treatment detassels with two leaves was significant different from the CK,its grain yield increased 525 kg·hm^-2 ,and gained 352 kg·hm^-2 dry-mater （2.84 hm^2 maize equivalent to 1 hm^2 rescue）at the same time. So detassel with two leaves and silage could reach the goal of increasing yield and maximum the beneficial. |
