Abstract: In order to provide theoretical basis and technological guide for cultivating wild Pteridium aquilinum, study on the influence of planting density and fertilizers on growth and yield of Pteridium aquilinum was conducted. The results showed that the low planting density(25cm×11cm) favoured the development of root stem under earth and increase in plant height and petiole length, but resulted in decrease of yield of the fresh Pteridium aquilinum. Under the conditions of chicken dung applying, the root stems under earth developed well, plant height and petiole length increased and the third year yield of the fresh Pteridium aquilinum was significantly higher than that of the fresh Pteridium aquilinum with the treatments of compound fertilizer applying, ash fertilizer applying and no fertilizer applying. Therefore, the high planting density(25cm×5cm) with chicken dung applying is the suitable combination measures for obtaining the highest yield of fresh Pteridium aquilinum.
