不同栽培方式下稻田千金子的成株与结实特性研究

Study on the Stubbing and Fructifying Traits of Red Sprangletopin Different Cultivating Ways of Rice

调查并研究了不同水稻栽培方式下千金子 [Leptochloachinensis(L .)Nees .]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。

Based on different cultivating ways of rice,the biological traits of stubbing and fructifying for subaqueous red sprangletop [Leptochloa chinensis(L.)Nees.]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.
