Abstract

摘要： 在基肥相同的条件下，设置不同施氮量（纯N 0、90、150、210 kg/hm2）和栽插密度（75万丛、60万丛、45万丛/ hm2）对云粳30号淀粉RVA谱特性的影响。结果表明，最高黏度、热浆黏度、崩解值、最终黏度、消减值以及到达最高黏度时间均随施氮量的增加而显著降低，开始糊化温度受施氮量的影响较小；不同栽插密度间云粳30号淀粉RVA谱特性变化较小，除最高黏度和崩解值在高栽插密度下比中、低密度下显著增加外，其余淀粉RVA谱特性受栽插密度的影响均较小；淀粉RVA谱特征值在施氮量和栽插密度的共同影响下，变异大小依次是消减值>崩解值>热浆黏度>最高黏度>最终黏度>到达最高黏度时间>开始糊化温度。
