| Abstract: | Sweet sorghum was painting elevation between 1850 and 2700 m in Qinghai Province. The yield of fresh forage varied from 61034 kg·hm^-2 in Qilian to 139 840.5 kg·hm^-2 in the county of Minhe.Furthermore, stalk brix appeared about 9.28% in Danma village, the county of Huangzhong, and 16.61% in Minhe. The quality was excellent and nutritious; the dominant maize. Indeed, the content of stalk brix was twice as high as that production and sheep body weight. Sweet sorghum was a kind of index of this sweet sorghum exceeded the in the maize. It could increase cows milk excellent feeding crop. Moreover, optimal cultivation technology was explored for the future production promotion. |
