Effects of Reseeding fine Forage on Production Performance and Forage Quality of Degraded Grassland in Zhaosu,Xinjiang
No-tillage reseeding is one of the important measures to improve degraded grassland,which plays an important role in improving grassland production performance,improving forage quality,and promoting soil nutrient cycling.In order to clarify the effects of reseeding of excellent forage on the production performance and forage quality of degraded grassland in Zhaosu,Xinjiang,this study took the degraded grassland of Zhaosu in Xinjiang as the research object,set up the non-reseeded grassland as the control,and reseeded Bromus inermis Leyss.,Elymus nutans Griseb.,Agropyron cristatum(L.)Gaertn.,Medicago varia,Onobrychis viciaefolia Scop.,Lotus corniculatus Linn.)in Zhaosu grassland.The results showed that the dry matter biomass of reseeding grassland increased by 36.92% and the crude protein content of forage grass increased by 4.38% on average compared with the control.The correlation between the dry matter biomass of Bromus inermis Leyss.and its influencing factors was 65.81%,while the Medicago varia correlation between the relative feeding value of forage grass and its influencingfactors was 67.55% .Therefore,no-tillage reseeding can improve the produc-tion performance and forage nutritional quality of degraded grassland.Among them,reseeding Bromus inermis Leyss.can significantly improve the production performance of degraded grassland,and reseeding Medicago varia can significantly improve the forage quality of degraded grassland.
