摘　　要：以"泰国柳叶蕹菜"为供试材料,设置不同基质栽培处理,比较研究不同基质栽培对成熟期蕹菜可溶性糖、硝酸盐和叶绿素含量的影响。结果表明:与CK相比,其它处理蕹菜的品质相对较好,其叶片可溶性糖含量和叶绿素含量均相对较高,而硝态氮含量相对较低,菜土添加一定比例食用菌渣或发酵稻草均可显著提高其可溶性糖含量,显著降低硝态氮含量;本研究设置条件下,菜土添加食用菌渣对叶绿素含量无显著影响,但是添加不同比例发酵稻草均可显著提高叶绿素A、叶绿素B及总叶绿素含量,不同栽培基质对蕹菜叶片叶绿素A与叶绿素B比例无显著影响。＂Thailand water spinach＂ was employed for the test material to research the effects of the different culture matrixes on soluble sugar content, nitrate, chlorophyll, respectively. The results showed that the quality for other treatments is better than CK, and its chlorophyll content, soluble sugar content are higher than CK, but its nitrate content lower than CK, vege- table soil with edible fungus residue or fermentative rice - straw as culture matrix for planting water spinach can significantly increased their soluble sugar content but significantly reduced nitrate content; In this experiment, there was no significant effect on soluble sugar content when vegetable soil with edible fungus residue as culture matrix but there was significant effect on chlorophyll（ehl. A, chl. B, chl. A ＋ B） content when vegetable soil with fermentative rice - straw as culture matrix for planting water spinach, there was no significant effect on the ratio of chl. A to chl. B under different culture matrix for plant- ing water spinach in the experiment.
