摘要： 本文调查和研究了不同水稻栽培方式下千金子湿生体的成株与结实的生物学特性。比较得出了其湿生体与旱长株的区别，明确了移栽、抛秧和直播田的千金子在株高、茎蘖数、匐匐茎数、匐匐茎分蘖数、穗长、穗分枝数、每穗花数和千粒重性状上的异同。

Abstract: Based on different cultivating ways of rice,the biological traits of stubbing and fructifying for subaqueous red sprangletop were investigated and researched. Some morphological difference between the subaqueous red sprangletop and the dryland-living one,such as their plant heights,stem tiller nodes,stolons,stolon tiller nodes,tassel lengths,tassel branches,followers per tassel,weights of thousand-grain and so on,in the rice fields with transplanting,seedling-broadcasting and direct-seeding ways were distinguished clearly.
