Abstract
In order to provide theoretical basis and technological gui de for cultivating wild Pteridium aquilinum, study on the influence of plant ing density and fertilizers on growth and yield of Pteridium aquilinum was c onducted. The results showed that the low planting density(25cm×11cm) favou red the development of root stem under earth and increase in plant height and pe tiole length, but resulted in decrease of yield of the fresh Pteridium aquilin um. Under the conditions of chicken dung applying, the root-stems under earth developed well, plant height and petiole length increased and the third-year y ield of the fresh Pteridium aquilinum was significantly higher than that of the fresh Pteridium aquilinum with the treatments of compound fertilizer app lying, ash fertilizer applying and no fertilizer applying. Therefore, the high p lanting density(25cm×5cm) with chicken dung applying is the suitable combin ation measures for obtaining the highest yield of fresh Pteridium aquilinum.关键词
