汕优63是我国唯一的部颁杂交稻优质米,遵义县于1986年首次引进试种。为了加速该组合在遵义县的推广速度,我们在全县的南白、枫香、龙坪等8个区的2500余亩种植了汕优63,并以遵义县近几年的当家杂稻组合汕优2号为对照,对该组合的主要特征特性和产量进行了初步的调查和测定。其结果如下: (一)生育期适中,为迟熟杂交稻 在遵义县范围内,海拔845～950M的地方,采用地膜育秧,两段育秧和地膜育小苗直播等方式种植,其汕优63的全生育期均在170～176天范围内变动;与汕优2号(170～177天)相近(见表1)
Shanyou 63 is the only ministerial-level hybrid rice of high quality rice, Zunyi County, introduced in 1986 for the first time.
