摘要:

本文作者采用NaCl溶液调配的六个等级浓度溶液对引种栽培在同质土壤上的同种生态型品种香根草进行浇灌,并观测其一个生长期,通过试验数据的统计分析了,不同土壤盐度对香根草引种成活率、分蘖率、越冬前幸存率、生物量积累率,以及叶绿素含量、根系长度、根径和重量等指标。发现香根草对土壤盐度有一个适应的范围,在该范围内适合香根草的生长发育,超过该范围将不利香根草生长发育。并建立了土壤盐度对香根草生长发育影响活力指标和模型,研究表明该方法是可取的,研究成果是可靠的,定性准确,定量合理。

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.
