Abstract

Abstract: At present, the degradation of natural grassland is serious in China. Reseeding is an important measure of the grassland improvement. Reseeding forage legumes into natural grassland which is dominated with grasses had significant function on the improvement of forage yield, the nutrition of forage, grassland quality and physical and chemical properties of soil. However, the measure was not applied to practice effectively. Reseeding techniques and the stability of grassland community are the problems needed to be solved urgently. The author discussed the reseeding techniques about selection of variety, the way of reseeding and reseeding time, and analyzed the change of forage yield, forage quality and physical and chemical properties of soil after reseeding legumes. In addition, the stability of grassland community after reseeding was also discussed at the aspect of inter-specific competition and coexistence of grasses-legume. While reseeding legumes into natural grassland, we should select suitable reseeding techniques and make use of the theory of inter-specific competition and coexistence in order to enhance the stability of grassland community and realize the resuming of grassland ecology.
