摘　　要：采用钵苗机插、常规毯苗机插、晚播晚栽机插、有机栽培等4种种植方式,研究不同栽培措施对南粳9108群体质量及其稻米品质的影响。结果表明:4种种植方式群体叶面积指数、干物质积累及单位产量由大到小均依次为钵苗机插、毯苗机插、晚播晚栽、有机栽培;品质方面,垩白粒率及垩白度由大到小均依次为钵苗机插、毯苗机插、晚播晚栽、有机栽培;相比其他栽培方式,有机栽培能适当提高直链淀粉含量和胶稠度,降低蛋白质含量,提高RVA特征谱峰值黏度和崩解值,改善南粳9108稻米外观和食味品质。This study conduted four planting patterns including seedling machine transplanting,conventional blanket seedling machine transplanting,late sowing late planting machine transplanting and organic cultivation to investigate effect of cultural practice on the population quality,yield structure and rice quality of Nanjing 9108.The results showed that,leaf area index,dry matter accumulation and yield showed seedling machine transplanting 〉blanket seedling machine transplanting 〉late sowing machine transplanting 〉organic cultivation,the chalky rice rate and chalkiness were seedling machine transplanting 〉blanket seedling machine transplanting〉 late sowing machine transplanting〉 organic cultivation.Compared with the other way of cultivation,organic cultivation increased the amylose content and gel consistency,reduced the protein content,and improved RVA characteristic spectrum peak viscosity and breakdown value.Organic cultivation can improve the appearance and taste quality of rice.
