摘要
研究不同土水势值对油菜的生长发育状况和叶水势、叶温、叶气孔阻力、蒸腾强度、叶细胞液浓度等生理性状,以及油菜的经济产量和生物学产量的影响。对油菜的适宜灌水势值指标进行了初步探讨。
The effects of three soil water potentials on the growth, leaf water potential, leaf temperature, leaf stom- atal resistance, transpiration rate, leaf cell sap consistance and economic and biological yield of rape were investigated. The optimum water potential value of irrigation for the rape was discussed.
