摘　　要：通过2009-2010年示范方资料分析,初步探明了超级稻品种武运粳24在机插条件下的生育规律和产量700 kg/667 m2的栽培技术指标。结果表明,武运粳24高产超高产是以足量的有效穗与较大的穗型,单位面积颖花量3000万以上,并保持正常的结实率和千粒重。配套栽培技术措施应围绕基质育秧、适期精量播种、插足基本苗、精确肥水运筹和综合防治病虫害等栽培手段,塑造超高产的库容量,实现稳定超高产。The growth development law and the cultivation technique with yield of 700㎏/ 667 m2 under mechanical planting were confirmed by the demonstration experiment from 2009 to 2010.The results indicated that the super high yield of Wuyunjing24 required effective panicle,at less 3000 spikelets per unit area,normal seed setting rate and 1000-grain weight.Improving seedling quality,precision planting,pest and disease control were the main cultivation techniques of Wuyunjing24 to stabilize super high yield.
