以菇渣、锯木屑、珍珠岩作为有机生态型栽培基质,采用单纯形-格式设计方法,研究这3种基质对菠菜产量和品质的影响。结果表明,菇渣在提高产量及维生素C含量、降低硝酸盐含量上影响最大,锯木屑在降低可溶性草酸含量上效果最好。通过综合选优后,得到菠菜高产优质的适宜基质配比为菇渣∶锯木屑∶珍珠岩=0.27∶0.5∶0.23。
Abstract：Scrap of woods,mushroom-grown cotton seed coat(MCSC)and perlite were used to act as ecological organic stroma,and simplex-lattice design method was applied to study the ef fects of the three stromas on yield and quality of Spinacia oleracea L.The results showed that MCSC had maximum impact on increasing the yield and Vit C content and decreasing nitrate content.How ever,the effect of scrap of woods on decreasing oxalate content was the best.Through a comprehen sive selection,the suitable proportion of stroma of high yield and quality was MCSC∶scrap of woods∶ perlite equalling to 0.27∶0.5∶0.23.
