土默川平原盐生植物碱蓬生长的土壤环境研究初探

Superficial Research the Soil Environment for the Growth of Halophyte and Suaeda Neteroptero Kitagaw in Tumuochuan Plain

通过研究盐生植被碱蓬生长的根际土壤与对照土壤理化性状的差异以及含盐特点,结果表明:碱蓬生长环境所需通气孔隙须在14%以上,土壤盐分组成中 Cl^-占阴离子总量的32%以上,土壤盐分组成中 CO_3^(2-)占阴离子的总量不超过5.7%,碱蓬适宜生长在以氯化物盐分为主的土壤环境。

In this thesis through researching the characters on the physics-chemistry and Salineness between root,s soil and contrasted soil.The results indicate that：the environment for suaeda neteroptera kitagaw growth must meet those dominates;the aeration porosity must be larger than 14%;the Cl^- consist of the soil sah,account more be large than 32% in total anion; the CO3^2- consist of the soil salt ,account be large 5.7% in total anion.Meanwhile the suaeda neteroptera kitagaw can easily live in the soil which mainly consist of chloride solon.
