摘要
本试验的研究结果表明:随着收割高度的增加,粗蛋白含量逐渐降低,收割高度从40cm至70cm,粗蛋白含量从平均22.67%降低至19.77%,但叶粗蛋白含量变化不明显。收割高度每增加10cm,饲料干料667m2产量约增加40kg,生育期约延长9天。综合考虑饲料产量、营养成分(粗蛋白含量)和生产成本,苎麻作为蛋白饲料开发,整株收割高度应在70cm以下。
The testing results indicate:Conte nt of crude protein of ramie for feed r educes as plant height of ramie rises.When the reaping heig ht rise to 70cm from 40cm,average con tent of crude protein lower to 19.97%from 22.67%.However,cont ent of crude protein of ramie leaves d oes not change obviously.The yield of dry ramie feed increases about 40kg and growing period delay a bout 9days by per 10cm rising of reaping height.Comprehen sively considering yield of feed,content of crude protein and pro-ducing cost,ramie for feed protein s hould be reaped below its 70cm plant height.
