摘要
以美国大速生菜为试材,以腐熟与未腐熟玉米秸秆替代草炭作为莴苣无土栽培基质中的主要材料,研究其对莴苣产量、叶面积、干物质量、光合速率、根系活力、维生素C和硝酸盐含量的影响。结果表明:T3处理(腐熟玉米秸秆∶蛭石=3∶1)基质配方最有利莴苣的生长。
According to the rapid growth lettuce of America for experiment material, use thoroughly decomposed maize straw and undecomposed maize straw instead of grass peat as the main material of lettuce＇s soilless culture base. To research the influence of lettuce output, leaf area, amount of dry matter, photosynthetic rate, root system vitality, vitamins C and nitrate content. The results showed that T3 deal with the base of （thoroughly decomposed maize straw： vermiculite= 3：1 ）formula was optimum growth for lettuce.
