| The study on forage yield and quality of AoYu5102 and other silage hybrids under different planting densities in different areas were carried in order to select silage hybrid suitable to Beijing area with high yield and quality. The results indicated: l)There were significant difference among varieties inforage yield, Neuter Detergent Fiber (NDF%) and Acidity Detergent Fiber (ADF%) . There were nosignificant difference in forage field among AoYu5102, ZhongBei410 and YaYu8, but those were muchhigher than NongDal08 and Liao625 significantly. In quality, NongDal08 and Liao625 were excellent; ZhongBei410 was good; AoYu5102 were common and YaYu8 were not good. 2) The forage yield were affected largely by the area. 3) The forage yield and NDF% were much affected by planting density. Higher planting density tended to increase forage yield and decrease the quality. 4) The interaction on forage yield were existed between variety and area and between variety and planting density only in TongZhou. The interaction on NDF were existed between variety and planting density. 5) In general, then study showed, ZhongBei410 was suitable to Beijing area, which produced high forage yield with good quality. |
