摘　　要：以武运粳7号为材料,研究超高茬麦田套稻与常规育秧不同带蘖秧苗的素质。结果表明,超高茬麦田套稻秧苗分蘖发生快、成穗数多、干物质积累量大,产量比常规育秧单茎苗高,与带3蘖的壮苗产量无明显差异,且具旱育秧及免耕田条件下秧苗根系活力强的优势,表明超高茬麦田套稻小麦让茬时黄瘦的单茎苗不是弱苗,是增产潜力大的秧苗。Rice variety Wuyunjing 7 was used as experimental material to compare the tillered seedling qualities between ultra-high stubble wheat interplanted rice and conventional planted rice. Panicles and dry matter accumulation of rice seedlings interplanted with ultra-high stubble wheat were more than those of conventional planted rice seedlings, so was the yield. Root vitality of rice seedlings interplanted with ultra-high stubble wheat in the no-tillage field was high. All the above facts indicated that the yellowish and slim rice seedlings interplanted with high stubble wheat at the stage of wheat harvest were not weak but potentially strong in yield increase.
