【摘要】 渗水膜覆盖提高了花生叶片光合效能并增强了花生抵抗逆境的能力。与普通地膜覆盖及对照相比,采用渗水膜覆盖花生叶片叶绿素含量、硝酸还原酶活性、细胞间隙CO2浓度、净光合速率、气孔导度以及蒸腾速率等生理指标均有不同程度的提高,而叶片脯氨酸含量和细胞膜相对透性则低于普通膜覆盖及对照。更多还原

【Abstract】 The water-permeability plastic film mulching could increase peanut leaf’s photosynthesis efficacy and strengthene peanut’s resisting ability to the adversity.Its chlorophyll content,nitrate reductase activity,intercellular CO₂ concentration,net photosynthesis rate,stomatal conductance,and transpiration rate of peanut leaves are improved to different degrees,while its praline content and cell membrane relative permeability are lower than the other two treatments.更多还原
