The results sho１w６８ed that regreened in the course of nature after winter or after transplant in the７s６e０t３wo８ cold places . The seed yield was kg / ha in Huhhot in the second year after planting . Additionally , the hay yield was . kg / ha in Hailaer in the second year after planting . Conclusions Galega oriental ３３ ３ Huhhot may be a suitable place for the seed breed base of although its seed yield was . kg/ ha Galega oriental １２％ lower than that in Tubi county , Xinjiang . hay was only reduction in Hailaer compared to Tubi , Xinjiang . Galega oriental This implicated that Galega oriental hay could be produced in Hailaer to meet the needs of in the local area . Therefore , planting might be of important value in Inner Mongolia .
