黄河三角洲不同程度盐碱化土壤对芦苇种子发芽的影响

摘要

The germination experiments with reed seed in different soil has varying salinization. Re-search on the response between the germination of reed seed and the different soil salinization shows that local farmland soil has a small impact on reed seed germination. With the increase in soil salinity, reed seed's germination is inhibited increasingly. Local paper making waste water also has very strong inhibi- tion in seed germination. Therefore we should take actions to suit local circumstances in the recover process of degraded saline wetland.%采用黄河三角洲地区不同程度盐碱化土壤及其土壤浸提液和造纸废水对芦苇种子的萌发进行试验,考察不同程度滨海盐碱土和造纸废水对芦苇种子萌芽的影响.研究结果表明:当地农田土壤对芦苇种子萌发的影响较小;轻度盐碱化、中度盐碱化和重度盐碱化土壤对芦苇种子发芽的抑制依次增强;造纸废水对芦苇种子萌发也有极强的抑制作用.因此在退化盐碱湿地的恢复过程中应当因地制宜,合理污灌.
