中文摘要：
以香根草为试材,采用人工配置含有一定浓度的NaCl或K2CO3盐碱的土壤为栽培基质,统计分析了香根草的成活率、分蘖率和生物量积累率,与香根草植株体内的盐分含量及栽培土壤中盐碱含量,并进一步测定了所栽培的香根草吸收土壤中盐分的质量和能力及土壤中减少的盐碱质量。结果表明：香根草对土壤中盐碱的吸收能力较强,在其生长发育过程中氯盐的吸收能力大于对碳酸盐的吸收;但对于土壤中的盐碱降解来说,碳酸盐的降解比氯盐容易;同时得出香根草对于盐碱土壤具有一定的修缮改良作用。
英文摘要：
Vetiveria zizanioides was used as test material,through artificially compounding soil with NaCl solution or the K2 CO3 solution in certain density,the author of this article had maken the statistical analysis of the survival rate and minute tiller rate and biomass accumulates rate of Vetiveria zizanioides,and of the salt content of in soil or in adult plant of Vetiveria zizanioides,and had further calculated the salinity quality in the cultivated Vetiveria zizanioides by absorbed from soil,and the ability of that the cultivated Vetiveria zizanioides absorbs salt and alkali from soil,and the quality of NaCl or K2 CO3reduced in the soil.The results indicated that the saline absorbancy of Veliveria zizanioides from the soil was strong,and the absorbancy of NaCl was more strong than the absorbancy of K2 CO3 for the Veliveria zizanioides from the soil,but as for the reduction of salt and alkali in soil,the reduction of K2 CO3was more easy than NaCl.And Vetiveria zizanioides be regarded that had function of restoring and ameliorating salt or alkaloid soil in certain degree.
