摘　　要：比较了３株沙棘Ｆｒａｎｋｉａ菌感染能力，Ｈｒ１６可与野生菌作用互补．测定了不同接种方式和多种环境因子对回接的影响．土壤表层施菌接种，菌龄８周，苗龄４周，接种量每株０．０１ｍｌＰＣＶ，可产生高效共生效果．Three Frankia strains (Hr8.Hr16 and Hr32) from Hippophae rhamnoides are tested for inoculation in soils with native Frankia species. Hr16 has a compensational effect with native species. The inoculation efficiency of Frankia is influenced by various factors. Higher efficiency is obtained while Frankia is inoculated in soils within 5cm in depth. The strains are cultured for 8 weeks, seedlings for 4 weeks and inoculation amount is 0. 05 ml PCV.
