【摘要】 以6个不同类型的饲用高粱品种为材料研究其粗蛋白的积累规律。研究结果表明,叶片中粗蛋白在生育期中呈现直线下降趋势,而茎秆、穗和全株粗蛋白含量则都呈现L形变化趋势,且前期下降迅速、后期下降缓慢。不同部位粗蛋白产量则呈现双峰变化趋势,且后一个峰值较高。更多还原

【Abstract】 With six forage sorghum cultivar as tested material,accumulating regulation of crude protein was studied.Results showed that crude protein content of leaf decreased linearly during the whole growth period,while crude protein content of stalk,ear and whole-plant were presented L-shaped trend,and crude protein content decreased rapidly at the early stage and slowly later.The dynamics of CP yield of different parts showed double peak trend,and the latter was higher than the former.更多还原
