Abstract:: Taking ‘Longshu No.1’ as test materials,potato stalk and soil water leach liquor were used,the allelopathic effect of potato continuous cropping on Solanaceae (tomato，eggplant and pepper) were studied.The results showed that the potato stalk water leach liquor inhibited germination and germination index of the three species.Peppers germinating capacities and the germ length of three species with liquor concentration increases showed a phenomenon of high levels inhibiting and low concentration promoting.Soil leach liquor inhibited the three species germination rate and germination index，but promoted the tomatoes and peppers germ growth.Potato stalk and soil water leach liquor both had allelopathy on three Solanaceae crops germination rate，germination index，radicle length and germ length，and also had certain concentration effect.
