| 摘 要： | 土壤盐渍化会严重影响作物生长发育及产量,在供试的3种作物中,油菜耐盐能力较差,棉花耐盐能力最强,大豆次之.在一定盐度范围内,作物某些生长性状和产量性状与土壤含盐量之间存在显著的哪相关关系.室内测试分析和田间调查表明:①油菜株高与土壤含盐量之间呈曲线相关,油菜单株结果数与土壤含盐量之间存在极显著的半对数线性相关关系;②大豆植株成活率与电导率EC25之间呈极显著的半对数线性负相关关系,其单株结荚数与EC25之间有极显著的线性负相关关系;③棉花成活率和土壤含盐量之间呈曲线相关,线型呈抛物线,棉花相对产量与土壤的含盐量呈线性负相关性.

| Abstract: | In this paper,three plant(cotton,soybean,rape) were involved,with different salt tolerance.The experiment results of laboratory analysis and surveys in the field showed:there was a curve correlation between the rape plant height and soil salt concentration and there was significant half logarithm correlation between the number of shells per plant and soil salt concentration;the relation between soybean survival rate and electronic conductivity rate was half logarithm linear negative,while between the number of shells perplant and electronic conductivity rate was significantly negative;cotton survival rate assumed a change of parabola curve under different soil salt concentration,while the relative yield of cotton was negatively correlated with soil salt concentration. |
