| 摘 要： | 通过设置在陇中黄土高原丘陵沟壑区的长期定位试验,研究了不同耕作措施下旱作春小麦和豌豆叶水势的变化特征及其与环境因子的关系.结果表明:免耕秸秆覆盖处理各生育期春小麦和豌豆叶水势的日均值均高于其它处理;整个生育期春小麦各处理的叶水势与土壤含水量之间呈显著正相关,其中免耕秸秆覆盖、免耕不覆盖、传统耕作秸秆还田处理下叶水势与土壤含水量之间达到极显著水平.不同保护性耕作措施下春小麦和豌豆叶水势与气温、大气相对湿度、太阳辐射显著相关,其中小麦和豌豆的大气相对湿度是影响春小麦叶水势日变化的最重要的气象因子.

| Abstract: | By setting long-term experiment in hilly and gully region of Loess Plateau,the leaf water potential and its relationship among the environmental factors of spring wheat and pea under different conservation tillage measures were studied.The results showed that the daily mean value of leaf water potential of spring wheat and pea in each growth period under no-tillage with straw cover treatment was higher than that under any other treatment.During the whole growth period,the leaf water potential of spring whea... |
