| 摘 要： | 为了改善大面积生产的水稻稻米品质,2015年和2016年以杂交中稻优质稻品种‘旌优127’、高产品种‘Ⅱ优602’为材料,通过分期播种并设置高氮低密与低氮高密两种栽培方式,研究了杂交中稻品种、气候及栽培方式互作对稻米品质的影响。结果表明,随着播种期推迟,整精米率、长宽比呈升高趋势,垩白度、胶稠度呈下降趋势,垩白粒率则呈"V"字型变化;高氮低密与低氮高密两个栽培方式间稻米品质差异不显著,栽培方式与年度、品种、播种期对稻米品质的互作效应均不显著;整精米率、垩白度、垩白粒率、长宽比同时受年度、播种期和品种的互作效应显著,胶稠度在年度和品种间互作效应显著,直链淀粉含量在播种期和品种间互作效应显著。对稻米品质影响程度的降序排列是品种、气候、栽培方式。有利于提高稻米品质的气象条件为:播种—移栽相对湿度小、日平均气温高,移栽—拔节期日平均气温低、日照时数少,拔节—齐穗期日最高气温低、日最低气温高、日均相对湿度低,齐穗—成熟期日照时数少。水稻抽穗前的气象因子通过改变穗粒结构而间接影响米质,抽穗后温度升高引起籽粒灌浆速度加快致稻米品质下降。
