不同有机生态型基质在上海青无土栽培上的应用研究

Application of Different Organic Ecotype Matrix to Soilless Culture of Brassica campestris

为探索菇渣与锯木屑替代草炭作为蔬菜基质栽培的可行性,采用草炭、菇渣、锯木屑和珍珠岩作为基质原料,并研究了不同原料配比在上海青无土栽培上的应用效果。研究结果表明:处理1(草炭:菇渣:锯木屑:珍珠岩=2:2:2:1)和处理5(草炭:菇渣:锯木屑:珍珠岩=4:2:2:1)两种基质配比的上海青植株生长形状均优于CK,处理1和处理5的根系活力、Vc含量均高于CK,硝酸盐含量均低于CK,处理1和处理5的叶绿素含量均高于CK。由此可见,采用菇渣、锯木屑和珍珠岩进行适当配比可研制出适合蔬菜种植的栽培基质,另外,处理1和处理5中的栽培基质可以作为上海青蔬菜栽培基质推广应用。

To explore the feasibility of mushroom residue and sawdust instead of peat as vegetable substrateculture, the authors took mushroom residue, sawdust, peat and perlite as substrate material, the applicationeffect of different material ratios in Brassica campestris soilless culture was studied. The results showed thatplant growth of treatment 1（peat： mushroom residue： sawdust： perlite=2：2：2：1） and treatment 5（peat：mushroom residue： sawdust： perlite=4：2：2：1） were better than that of CK, the root activity, vitamin C contentand chlorophyll content of treatment 1 and treatment 5 were higher than that of CK, NO3-content was lowerthan that of CK. The proper ratio of mushroom residue, sawdust and perlite could be developed for vegetableplanting cultivation matrix. In this study, the cultivation medium of treatment 1 and 5 could be used ascultivation medium in Brassica campestris soilless culture.
