摘　　要：以辐照灭菌的酸性黄壤（ｐＨ５６）为供试土，种植有性繁殖的茶苗（Ｃａｍｅｌｉａｓｉｎｅｎｓｉｓ）并接种ＶＡ菌根真菌（Ｇｌｏｍｕｓｃｉｔｒｉｃｏｌｕｍ），以不接种菌根真菌为对照，分别追施３２Ｐ过磷酸钙和８６Ｒｂ氯化铷（代替４０Ｋ）。试验结果证明：菌根浸染率，３２Ｐ组合为５２６０％、８６Ｒｂ组合为５６７０％，茶树株高分别是对照的２１０倍和２５０倍，对磷、钾元素的吸收量分别比对照增加４６０和３１０倍，磷肥利用率提高１４１０％、钾肥利用率提高１７１３％。Tea(Camellia sinensis)seeds were sown on sterilized acitic yellow soil(pH5 6)in a pot experiment and treated as follows:1)inoculated with VA mycorrhizal fungus(Glomus citricolum),2)nonmycorrhizal as control,top dressed with 32 P single superphosphate(M 32 P)and 86 Rb rubidium chloride(M 86 Rb).The results showed that the percentage of VA mycorrhizal infection was 52 6% for M 32 P and 56 7% for M 86 Rb. Plant height,dry weight and the uptake of phosphorus and potassium were 2 1 and 1 8 times,2 4 and 2 5 times,5 6 and 4 1 times as that of control respectively.The utilization rate of phosphorus and potassium were raised by 14 10% and 17 13% respectively.
