摘要：Foliar litters from 5 commonly planted intercorpped trees were collected and decayed within soil of local farm. These soil samples containing different amount of decomposed litters were then used as culture medium for a germination and seedlings growth testing of soybean. The allelopathic effects of intercropped trees on soybean were assessed. The results indicated that Eucommia ulmoides , Paulownia fortune and Acer truncatum litters showed promotional effects at relative low concentration (75-150 g litters decomposed in 6.5 kg soil, that is 75-150 g/pot), but inhibitory effects at high concentration (300 g/pot), thus these trees should be planted with soybean with a low intercrop proportion. Populus Canadensis litters showed promotional effects at low and high concentration (75 or 300 g/pot), but inhibitory effects at moderate concentration (150 g/pot) and this tree should be planted with a moderate intercrop proportion. Zanthoxylum bungeanum litters exhibited promoting effects at all concentrations, thus this tree was recommened to be planted with soybean with any tested intercrop proportion.
