摘　　要：水溶性铜锌复合微肥对花魔芋光合特性有很大影响:喷施2次后花魔芋叶片光合速率、蒸腾速率、叶绿素分别提高541.11%、64.20%、67.78%,胞间CO_(2)浓度降低35.88%;花魔芋地径、株高和叶盘分别增加23.3%、增加22.5%、25.5%;处理后的魔芋植株更高,叶片更宽大,具有更大的光合面积和更强的光合特性,倒苗时间延后20天以上,总产量增加38.31%。The water-soluble copper zinc compound microelement fertilizer had a great impact on the photosynthetic characteristics of Amorphophallus konjac.After twice spraying,the photosynthetic rate,transpiration rate and chlorophyll of Amorphophallus konjac leaves increased by 541.11%,64.20%and 67.78%respectively,and the intercellular CO_(2)concentration decreased by 35.88%;The ground diameter,plant height and leaf disc of Amorphophallus konjac increased by 23.3%,22.5%and 25.5%respectively;After treatment,the konjac plants were taller,the leaves were wider,the photosynthetic area was larger and the photosynthetic characteristics were stronger.The total yield increased by 38.31%when the time of seedling inversion was delayed more than 20 days.
