摘要
本研究对河北省赞皇县、高邑县、望都县、河北农业大学标本园等地枣树的ＶＡ菌根自然侵染率进行了调查。结果表明：所调查的枣树均有ＶＡ菌根菌侵染，但ＶＡ菌根的自然侵染率因立地条件、树龄、品种不同而异。树龄越大，侵染率越高；土壤肥力高或过低均不利菌根菌的侵染。
Natural occurrence of vesicular-arbuscular mycorrhizal (VAM) fungi in Chinese jujube trees was investigated in Zanhuang, Gaoyi, Wangdu county and the garden of Hebei Agricultural University. The results showed that VAM fungi were present on all the trees but the percentage infection varied with locality, variety and the age of the trees. The older the trees, were the higher the percentage infection bacame. The trees planted in both fertile and sterile soil had lower percentage infection.
