| 摘 要： | 对两种不同用途饲用玉米的干物质积累和各器官的分配研究发现,青贮型玉米科多8号的干物质生 产主要集中在吐丝以前,茎叶鞘中的物质分配较多,约占总量的59％;粮饲兼用型玉米的干物质积累主要集中 在吐丝以后,穗子中的干物质分配较多,约占总量的50％。可见,青贮型玉米科多8号主要注重前期茎叶鞘等 茎秆产量的生长,粮饲兼用型玉米陕单310主要注重后期籽粒产量的形成。

| Abstract: | Through analysis dry matter accumulation and every organic distribution of different feeding type maize, it is founded that fodder maize of keduo 8 dry matter accumulation is mostly collected before spin, and hydrated number of plant is dropped slow in anaphase. But generative growth Period of shaandan 310 is longer, its dry matter accumulation is mostly collected after spin, and hydrated number of plant is dropped rapidness in anaphase. That is said that ensilage maize of keduo8 is mostly growth of stem including stem and leaf and vagina, but food and fodder dual-purpose maize of shaandan310 is mostly growth of grain. |
