摘  要：
通过田间试验设计覆秸旱作、水作和传统旱作3种栽培方式,分别测定山栏稻的抗旱生理指标、农艺性状和产量构成因素。结果表明:水作减轻了山栏稻受干旱胁迫程度,降低了剑叶的POD,MDA以及可溶性蛋白的含量,提高叶绿素含量,而覆秸旱作亦有类似效应但效果不如水作。与普通旱作相比,水作和覆秸旱作山栏稻株高分别提高30.62%和16.69%,叶长分别增长14.32%和6.62%,有效分蘖数分别增加64.7%和26.47%,生育期分别缩短12 d和5 d,产量分别提高267.44%和91.04%。山栏稻在水田环境下具有减少干旱胁迫、优化农艺性状和提高产量等诸多优点。本研究旨在为山栏稻从传统山区旱地种植引向普通旱作和水田种植("山栏下山")提供科学的依据。

摘  要：
Shanlan upland rice was cultivated under three patterns:paddy,rice-straw mulching and upland to determine their drought-tolerant physiological parameters,agronomic traits and yield components in the field trial.The results showed that the paddy cultivation alleviated drought stress on Shanlan upland rice,reduced the contents of POD,MDA and soluble protein and increased the chlorophyll content of the flag leaves.Rice straw mulching had similar,although less,effect to the paddy cultivation.Compared with the conventional upland cultivation,the paddy and rice straw mulching cultivation increased the plant height of Shanlan upland rice by 30.62% and 16.69%,the flag leaf length by 14.32% and 6.62%,the available? tillers by 64.7% and 26.47% and the yield by 267.44% and 91.04%,and shortened the growth stage by 12 and 5 days,respectively.Under paddy field conditions Shanlan upland rice has many advantages such as lower drought stress,optimal agronomic traits and higher yield.This study may provide a scientific basis for further research on cultivation pattern of Shanlan upland rice shifting from traditional upland to paddy field.
