为筛选温室黄瓜有机生态型无土育苗基质，采用随机区组设计，对6种不同基质进行比较。结果表明:采用玉米秸秆、食用菌下脚料、蛭石、牛粪按体积比1∶1∶2∶0.5配制的基质，黄瓜的出苗率、株高、茎粗、叶片数与根冠比均为最高；同时幼苗的光合能力最强。根系活力最强、叶片的SOD与POD活性最大，说明该基质配比更利于黄瓜壮苗的培育。

In order to obtain the soilless substrate for cucumber organic and ecological seedlings in greenhouse， six different substrates were compared by random block arrangement test design. The results showed that the ratio of corn straw∶edible scraps∶vermiculite∶cow dung = 1∶1∶2∶0.5 ratio of substrate， cucumber seedling emergence rate， plant height， stem diameter， leaf number and root-cap ratio on the character of numerical were all the highest. At the same time， seedlings maintain a strong photosynthetic capacity. Cucumber seedlings maintain the strongest root activity and the activity of SOD and POD were the highest in leaves. It indicates that the matrix ratio is more conducive to the cultivation of strong cucumber seedlings.
