摘　　要：通过盆栽试验,研究了外源添加物蚯蚓粪、活性炭、过磷酸钙对地黄[Rehmannia glutinosa(Gaert.)Libosch.ex Fisch.et Mey.]在连作(连作一年、连作两年)土壤中生长的影响。结果发现,蚯蚓粪,特别是高添加量(30%)的蚯蚓粪可以明显提高连作地黄的地上部和地下部的生物量,大幅提高连作两年地黄的成活率,明显改善地黄的连作障碍;活性炭和过磷酸钙也可在部分程度上提高连作地黄的生物量和生理指标,但总体效果不如蚯蚓粪。Pot experiment was used to study the effect of exogenous additives on some growth and physiological traits of Rehmannia glutinosa（Gaert.） Libosch. ex Fisch. et Mey. under of continuous cropping conditions. The results indicated that the aboveground and belowground biomass of R. glutinosa and the survival rate of two stubble continuous cropping R. glutinosa could be significantly improved by vermicompost, especially the high dosage（30%）. And addition of wormcast could obviously improve the continuous cropping R. glutinosa. Activated carbon and phosphate could certainly improve the biomass and physiological indexes, but the effect was not as good as wormcast.
