通过测定不同季节水曲柳－落叶松混交林4种落叶松根际和非根际土的酚酸（2，4－二羟基苯甲酸、7－羟基香豆素、阿魏酸和松香酸）的质量分数，研究了酚酸对水曲柳幼苗生长、根系活力和菌根侵染率的影响。结果表明：（1）施加落叶松根际土的处理中，7－羟基香豆素＋阿魏酸组合的处理对水曲柳幼苗生物量及根系活力均起促进作用，但非根际土中的7－羟基香豆素＋阿魏酸组合处理却产生抑制作用。（2）根际土与非根际土中的2，4－二羟基苯甲酸＋松香酸、7－羟基香豆素＋松香酸、7－羟基香豆素＋阿魏酸＋松香酸组合均显著抑制水曲柳幼苗生物量；2，4－二羟基苯甲酸＋7－羟基香豆素、2，4－二羟基苯甲酸＋7－羟基香豆素＋阿魏酸组合均显著抑制水曲柳幼苗根系活力，而2，4－二羟基苯甲酸＋阿魏酸组合却显著促进根系活力。（3）根际土与非根际土中的2，4－二羟基苯甲酸＋7－羟基香豆素＋阿魏酸均促进菌根侵染率；根际土的2，4－二羟基苯甲酸＋7－羟基香豆素促进菌根侵染率，而非根际土的2，4－二羟基苯甲酸＋7－羟基香豆素却抑制菌根侵染率。
通過測定不同季節水麯柳－落葉鬆混交林4種落葉鬆根際和非根際土的酚痠（2，4－二羥基苯甲痠、7－羥基香豆素、阿魏痠和鬆香痠）的質量分數，研究瞭酚痠對水麯柳幼苗生長、根繫活力和菌根侵染率的影響。結果錶明：（1）施加落葉鬆根際土的處理中，7－羥基香豆素＋阿魏痠組閤的處理對水麯柳幼苗生物量及根繫活力均起促進作用，但非根際土中的7－羥基香豆素＋阿魏痠組閤處理卻產生抑製作用。（2）根際土與非根際土中的2，4－二羥基苯甲痠＋鬆香痠、7－羥基香豆素＋鬆香痠、7－羥基香豆素＋阿魏痠＋鬆香痠組閤均顯著抑製水麯柳幼苗生物量；2，4－二羥基苯甲痠＋7－羥基香豆素、2，4－二羥基苯甲痠＋7－羥基香豆素＋阿魏痠組閤均顯著抑製水麯柳幼苗根繫活力，而2，4－二羥基苯甲痠＋阿魏痠組閤卻顯著促進根繫活力。（3）根際土與非根際土中的2，4－二羥基苯甲痠＋7－羥基香豆素＋阿魏痠均促進菌根侵染率；根際土的2，4－二羥基苯甲痠＋7－羥基香豆素促進菌根侵染率，而非根際土的2，4－二羥基苯甲痠＋7－羥基香豆素卻抑製菌根侵染率。

A pot experiment was conducted to study the effects of applying four kinds of Larix gmelinii rhizosphere and bulk con -centration phenolic acid from a Fraxinus madn shurica-L.gmelini mixed plantation on the growth of F.mandshurica seed-lings.In applying rhizosphere concentration phenolic acid , the combination of 7-hydroxyl coumarin and ferulic acid im-proved the F.mandshurica seedlings biomass and root activity , respectively , while the combination of 7-hydroxyl coumarin and ferulic acid of bulk concentration inhibited seedlings growth .All the combinations of 2, 4-2 hydroxy benzoic acid and abietic acid, 7-hydroxyl coumarin and abietic acid;7-hydroxyl coumarin, ferulic acid and abietic acid significantly inhibi-ted F.mandshurica seedling growth .All the combinations of 2, 4-2 hydroxy benzoic acid and 7-hydroxyl coumarin , 2, 4-2 hydroxy benzoic acid , 7-hydroxyl coumarin and ferulic acid significantly inhibited F.mandshurica seedlings root activities , while the combination of 2, 4-2 hydroxy benzoic acid and ferulic acid could improve seedlings root activities .The combi-nation of 2, 4-2 hydroxy benzoic acid , 7-hydroxyl coumarin and ferulic acid improved F .mandshurica seedling mycorrhi-zal infection incidence. The combination of 2, 4-2 hydroxy benzoic acid and 7-hydroxyl coumarin of rhizosphere concentra-tion could improved F.mandshurica seedling mycorrhizal infection incidence , while the same combination of bulk concen-tration inhibited seedling mycorrhizal infection incidence .
