摘要
甜高粱在青海海拔1850m-2700m种植,鲜草产量61 034 kg·hm-2(祁连)-139 840.5 kg·hm-2(民和),茎秆糖锤度9.28%(湟中县丹麻村)-16.61%(民和)。品质优良,营养丰富,绝大多数指标优于玉米,茎秆糖锤度平均比玉米高1.0倍。可提高奶牛产奶量和羊体重。甜高粱是一种品质优良的饲料作物。为在生产上推广种植,提出了甜高粱栽培技术。
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.
