摘　　要：以蜘蛛抱蛋属植物为试材,采用分光光度法测其叶绿素含量,研究了不同遮荫条件和栽培基质对蜘蛛抱蛋属植物光合作用的影响,以期为蜘蛛抱蛋属植物的栽培提供参考依据。结果表明:在遮荫率为98%条件下,采用JZ1或JZ4栽培基质(沙∶黄土∶营养土=1∶1∶1或1∶2∶1)进行种植时,有利于提高蜘蛛抱蛋属植物的光合作用,提升该属植物叶片的观赏价值。遮荫率为84%条件下,蜘蛛抱蛋属植物叶片叶绿素a、叶绿素b、叶绿素总含量以及类胡萝卜素含量的平均值分别为131.66、67.72、200.39、33.37 mg·g^(-1);遮荫率为98%条件下,叶绿素a、叶绿素b、叶绿素总含量以及类胡萝卜素含量的平均值分别为164.81、87.88、252.41、34.08 mg·g^(-1)。在遮荫率为98%条件下,采用JZ1和JZ4栽培基质时,蜘蛛抱蛋属植物叶片叶绿素总含量最高,分别为279.13 mg·g^(-1)和277.50 mg·g^(-1);采用栽培基质JZ3和JZ5时,类胡萝卜素含量最高,分别为38.54 mg·g^(-1)和38.25 mg·g^(-1)。Aspidistra plants was used as the experimental material,the spectrophotometric method was used to explore the impact of different shading conditions and cultivation substrates on the photosynthetic processes of Aspidistra,in order to provide reference for the cultivation of Aspidistra plants.The results showed that the average values of chlorophyll a,chlorophyll b,total chlorophyll and carotenoid content in the leaves of Aspidistra were 131.66,67.72,200.39,33.37 mg·g^(-1),respectively,under the condition of shading rate of 84%.Under the shading rate of 98%,the average values of chlorophyll a,chlorophyll b,total chlorophyll and carotenoid content were 164.81,87.88,252.41,34.08 mg·g^(-1).Under the condition of a shading rate of 98%,when JZ1 and JZ4 were used as cultivation substrates,the total chlorophyll content in leaves of Aspidistra was the highest,which was 279.13 mg·g^(-1)and 277.50 mg·g^(-1),respectively.When JZ3 and JZ5 were used,the carotenoid content was the highest,which was 38.54 mg·g^(-1)and 38.25 mg·g^(-1),respectively.
