摘要
针对当前春夏青绿饲草短缺现状,试验以2001年引入的杂交甜高粱新品种——甜格雷兹Sorghum bicolourvar.Sugargraze为试材,进行刈割次数研究。结果表明:随着刈割次数的增加,鲜草、干草和粗蛋白产量降低,单位品质含量增加。其中1次刈割产鲜草、干草和粗蛋白质量最高,分别为:110.78、29.75和1.25 t/hm2,2次刈割次之,且糖锤度高,适口性好,利于饲喂;3次刈割则较低,不宜采用。
Clipping frequency of Sugargraze, a new hybrid variety of sweet sorghum introduced in 2001, was studied. The result showed that with the increasing of clipping times, fresh and dry yield, crude protein reduced, but the unit content increased. Cutting only once had the highest fresh, dry yield and crude protein of 110 780, 29 750, 1 250 kg/hm^2, respectively; the treatment of 2 cuttings followed, but with higher stem sugar content; 3 cuttings was the worst and should not be used.
