| 摘 要： | 通过田间试验,采用现代先进的作物生理生态监测仪器,研究了不同保墒灌溉措施对夏玉米生态和生理指标的影响。结果表明,保墒灌溉措施能够有效促进作物生长,夏玉米株高与茎粗之间的关系可以近似用指数方程式来表示,其相关系数高于0.7。同时,保墒灌溉措施能够提高作物的叶片叶绿素含量、有效蒸腾和光合速率,对单叶片水平水分利用效率贡献甚微,各指标基本以地膜覆盖最高佳,秸秆覆盖次之,PAM处理较差。

| Abstract: | Based on the monitoring and analysis of field experiments,used the advanced modern advanced crop physiological and ecological monitoring instruments,we studied the Ecological and physiological indicators of maize under different moisture conserving irrigation(MCI).The result showed that he measurement of MCI can Promote crop growth and the relationship between the height and diameter is index formula,the correlation coefficient is higher than 0.7.At the same time,the measurement of MCI can advance the crop ... |
