摘　　要：设置18个杂交稻组合作低留桩再生力筛选简比试验,测定两季稻谷产量、产量构成因子、再生季有效节位与田面的距离、生育期及主要性状,结果表明:天优华占、宜优115、新两优223和Y两优1号低节位再生力较强,头季和再生季产量都较高,可作为低留桩再生稻推广种植。A simple comparison test to screen regeneration capacities of low - stubbles of 18 hybrid rice combination was car-ried out. The grain yields in two cropping season, yield component factors, the distance between effective nodes of ratooning rice and field surface, growth period and main traits were observed and determined. The results showed that, Tianyouhua- zhan, Yiyou 115, Xinliangyou 223 and Y liangyou No. 1 had strong regeneration capacity of the lower parts, both yields in the first and Ratooning cropping seasons were higher, could be planted as low-stubble ratooning rice.
