摘要
对格拉姆柱花草的刈割次数与生产性能关系进行了两年时间的研究,结果表明:不同年度、不同次数刈割对生产性能影响很大,当年刈割一次比刈割两次产草量增长44%—68%,粗蛋白产量增长40%左右;第二年刈割两次比刈割一次产草量增长4.8%,粗蛋白产量增长52%,而比刈割三次产草量增长17%,粗蛋白产量增长9%。
The relation between the productivity and cutting times of Stylosanthes guianensis had been investigated for two years.The results showed that the productivity was greatly influenced by different years and differ- ent cutting times.The yields of grass and crude protein of one-time cutting grass respectively increased 44%-48% and approximately 40% than that of two-times cuttings in the same year.Next year the grass and crude protein yields of two-times cutting grass respectivety increased 4.8% and 52% than that of one-time cutting's,and increased 17% and 9% than that of three-times cutting's.
