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 Qyou 6 as materials, the effects of different transplanting methods (mechanical transplanting and artificial planting) on the growth characteristics and yield of super-hybrid indica rice were studied. The results showed that leaf area index, specific leaf area, leaf area ratio and photosynthetic potential of machine-inserted rice were higher than those of planted rice in the middle growing stage (jointing stage to heading stage), dry matter accumulation, net assimilation rate, crop growth rate The dry matter accumulation in mature rice was higher than that in hand-planted rice, which was mainly attributed to the higher crop growth rate from heading to maturity than that in hand-planted rice. The nutrient uptake of organic rice during the whole growth period Lower than that of hand-planted rice; the effective panicle number and 1000-grain weight of machine-inserted rice were higher than those of hand-planted rice, while the total grain number and seed setting rate per panicle were lower than those of hand-planted rice.
