摘　　要：以准两优527和Q优6号为材料,研究了不同栽插方式(机械移栽和人工手栽)对超级杂交籼稻生长特性和产量的影响。结果表明,在生育中期(拔节期至抽穗期),机插稻叶面积指数、比叶面积、叶面积比率、光合势均高于手栽稻,干物质积累量、净同化率、作物生长率均低于手栽稻;成熟期机插稻干物质积累量高于手栽稻,主要是由于抽穗期至成熟期作物生长率高于手栽稻;全生育期内机插稻养分吸收量均低于手栽稻;机插稻有效穗数和千粒重高于手栽稻,而每穗总粒数和结实率低于手栽稻,产量与手栽稻无显著差异。Using Zhunliangyou 527 and Q You 6 as the materials,the effects of different planting patterns—machine transplanting（ MT） and hand transplanting（ HT） on growth characteristics and yield of super indica hybrid rice were studied. The results showed that the leaf are index,specific leaf area,leaf area rate and photosynthetic potential of machine transplanted rice（ MTR） were significantly higher than those of hand transplanted rice（ HTR）,while the dry matter accumulation,net assimilation rate and crop growth rate of MTR were significantly lower than those of HTR in the middle growth stages from the jointing stage to the heading stage. The dry matter accumulation of MTR was higher than that of HTR at the maturity stage as a result of a higher crop growth rate of MTR from heading to maturity stage. In whole growth period,the nutrient uptake of MTR was lower than that of HTR. The number of effective panicles and 1 000-grain weight of MTR were greater than those of HTR while the number of total spikelets per panicle and seed setting rate were less than those of HTR. As a result,the actual yield of MTR was not significantly different from that of HTR.
