采用不同等级的NaCl溶液或K2CO3溶液定期定量浇灌引种栽培的香根草,通过3个月试验研究观测,统计分析了香根草的引种成活率、分蘖率和生物量积累率及香根草植株体内的盐分含量,并进一步测定计算了引种栽培的香根草吸收土壤中盐分的质量和能力。试验结果表明:香根草对土壤中盐分的吸收能力较强,香根草对于土壤中盐分的吸收能力与土壤中盐度有关,同时对土壤中盐分的吸收是选择性的。并指出了进一步研究的方向。
With the different rank NaCI solution or the K2CO3 solution regular quota irrigation introduction cultivation Veliveria zizanioides, the author of this article had done three month experimental study observation, and had maken the statistical analysis Veliveria zizanioides's the introduction survival rate and Minute tiller rate and biomass accumulates rate salt content in adult plant of Veliveria zizanioides, and further determined has calculated in the introduction cultivated Veliveria zizanioides absorption soil the salinity quality and ability. The experimental study indicated that the salinity absorbancy of Veliveria zizanioides from the soil is strong, the Veliveria zizanioides be regarded that the salinity absorbancy from soil is relate with the salt content of soil, and simultaneously, the salinity absorption from soil of Veliveria zizanioides is selective. In the end of this article, the author had pointed out further studies direction and forecast.
