摘　　要：通过田间试验表明:在硫酸盐渍化土壤上,土壤含盐量影响着白沙蒿Artemisiasphaerocephala的生长发育,土壤含盐量在0.688%以下,生长发育正常;含盐量在0.859%时,生长发育受到抑制;含盐量在1.019%以上时,不能存活。随着土壤含盐量的增加,场圃出苗率、存活率、地上生物量和产种量逐步降低,冠幅变小,展叶期、落叶期、果实成熟始期推迟,而对花期、果实成熟盛期、植株高度几乎没有影响。The result of field experiment showed that the salt content in sulphate salinized soil influenced the growth of Artemisia sphaerocephala When the salt content was under 0 688%,the growth of the Artemisia was normal When the salt content was at 0 859%,the growth of the Artemisia was restricted And when the salt content was above 1 019%,Artemisia was dead Following increase of salt content,the germination rate,survival rate,aboveground biomass and seed production decreased gradually The plant crown became small,and the phase of leaf stretching,leaf shedding and beginning of fruit riping would be deferred However,the blooming, fruit ripping and plant height was almost not to be influenced
