| 摘 要： | 为给小麦优质栽培提供理论依据,以淮麦19和烟农19为材料,研究了地力水平、施氮量对小麦淀粉RVA特性的影响.结果表明,地力水平、施氮量对RVA谱特征值的影响除个别指标外,均达到显著或极显著的差异.在RVA特征值中,峰值黏度、热浆黏度、崩解值、最终黏度、消减值、峰值黏度时间和回复值存在显著的地力与品种互作效应.两供试品种在高、中、低三种地力水平上,RVA谱曲线均随施氮量的增加而降低.峰值黏度、热浆黏度、崩解值、最终黏度、回复值、峰值黏度时间随施氮量的增加而显著或极显著下降. |

| Abstract: | Took Huaimai19 and Yannong19 as materials,the effects of nitrogen application rate on RVA profile characters under different land fertility levels were studied.The results showed that soil fertility levels and nitrogen rate had significant or extremely significant effect on RVA profile characteristics except one or two characteristics.The mutual effect of soil fertility level and cultivar was remarkable in peak viscosity,hot viscosity,breakdown,cool viscosity,setback,peak time and consistence.With the incre... |
