Abstract:

Abstract：The author of this article had used six rank density solution which the NaCl solution mixes to the introduction cultivation on the homogeneity soil homogeneous ecotype variety fragrant root grass to carry on the irrigation, and observes its vegetal period front, through the tentative data statistical analysis, the different soil salinity to the fragrant root grass introduction survival rate, has divided the tiller rate, survives the winter fortunately survives rate, the biomass accumulation rate, as well as targets and so on chlorophyll content, root system length, root diameter and weight.Discovered the fragrant root grass has an adaptation scope to the soil salinity, suits the fragrant root grass in this scope the growth growth, will surpass this scope to be disadvantageous the fragrant root grass growth growth. And has established the soil salinity to the fragrant root grass growth growth influence vigor target and the model, the research indicated this method is may take, the research results are reliable, qualitative accurate, the quota is reasonable.
