摘要
探讨草地盐碱化对角果碱蓬出苗及生长的影响。试验结果表明,样地1、样地2和样地3土壤pH值及可溶性盐含量分别为10.10及0.59%、10.55及0.73%、10.58及1.14%,各样地出苗数分别为1143.13株/m2、71.25株/m2和99.59株/m2,样地1角果碱蓬平均株高为34.63cm,样地2和样地3角果碱蓬平均株高只有21.0cm和11.5cm,与样地1角果碱蓬株高差异达极显著水平,株高与土壤可溶性盐之间呈极显著负相关(R2=-0.921)。
This paper will study the effect of grassland salinization on the sprouting and growing of Suaeda corniculata.The results of the experiment are as follows.The soil pH of the sample plot one,sample plot two and sample plot three is respectively 10.10,10.55 and 10.58.And the amount of soluble salt of the sample plot one,sample plot two and sample plot three is respectively 0.59%,0.73% and 1.14%.The sprouting amounts of each sample plot is respectively 1143.13、71.25and 99.59 plant/m2.The average plant height of Suaeda corniculatathe in the sample plot one is 34.63cm,but those of sample plot two and sample plot three are only 21.0cm and 11.5cm.The difference between the sample plot one and the rest sample plots in the the average plant height of Suaeda corniculatathe reaches the significant level.There shows the significant negative correlation between the plant height and the amount of soluble salt in the soil(R2=-0.921).
