9种盐生植物对克拉玛依盐碱地绿化脱盐效果研究

Effects of 9 Halophytes on Greening and Desalination of Karamay Saline-alkali Land

2017~2018年在克拉玛依市南新公园开展盐碱地园林绿化试验,研究9种荒漠盐生植物(草本4种、灌木5种)对盐碱地的绿化脱盐效果。结果表明:9种盐生植物均有较好的脱盐效果,土壤表层0~20cm脱盐率达49.79%~71.05%,总脱盐率为35.61%~57.49%。野艾蒿、黄花补血草、盐地碱蓬、刚毛柽柳土壤脱盐效果较好;铃铛刺、白皮锦鸡儿和多枝柽柳土壤脱盐率较低。9种盐生植物中,盐地碱蓬的耐盐性最强,其次是黄花补血草、刚毛柽柳和野艾蒿;乌拉尔甘草、白皮锦鸡儿和铃铛刺的耐盐性相对较弱。

In 2017—2018,a greening experiment was conducted on saline-alkali lands in Nanxin Park in Karamay.9 desert halophytes(4 herbs,5 shrubs)effect on greening and desalting of saline land were studied.The results showed that:all 9 halophytes had better desalination effects.The desalination rate of soil surface 0~20cm reached 49.79%~71.05% and the total desalination rate was 35.61%~57.49%.The soil desalinization effect of Artemisia lavandulaefolia DC.,Limonium aureum(L.)Hill.,Suaeda salsa(Linn.)Pall.,Tamarix hispida Willd.are better;the desalination rate of soils of Halimodendron halodendron(Pall.)Voss,Caragana leucophloea Pojark.,and Tamarix ramosissima Ledeb.are lower.And Suaeda salsa(Linn.)Pall.has the strongest salt tolerance,followed by Limonium aureum(L.)Hill.,Tamarix hispida Willd.,Artemisia lavandulaefolia DC.;and Glycyrrhiza uralensis Fisch.,Caragana leucophloea Pojark.,Halimodendron halodendron(Pall.)Voss are relatively weak.
