饲用甘蔗闽牧42在贵州南部的适应性种植试验

Adaptability test on forage grass sugarcane Minmu42 in the South of GuiZhou

2001～2002年对饲用甘蔗闽牧42在贵州南部进行引种试验。结果表明:饲用甘蔗闽牧42耐热、抗旱能力特强,较耐寒、瘠,在贵州南部种植能安全越冬,生长天数为254天左右。闽牧42的分蘖能力较强,单株分蘖一般为28个左右,生长速度快,株高60～100cm时开始刈割,年刈割5次,全年鲜草产量可达150t/hm2左右。鲜草品质佳,其中脂肪含量为3.73%、蛋白质含量为9.58%、粗纤维含量为40.73%、粗灰分含量为7.63%、Ca含量为0.82%、P含量为0.36%、无氮浸出物含量为31.7%是贵州南部地区推广种植的一种优质高产饲料作物。

Adventitious txperiment from 2001 to 2002 in the south of GuiZhou showed:Forage grass sugarcane Minmu42 could strongly resist heat and drought.Also cold-resistant barren-resistant.It can pass winter safely and it's growing time is 254 days in the south of GuiZhou.Minmu42 tiller ability generally could reach 28 branches.When it grew about 60-100cm it began to reap,which could be reaped 5 times.Fresh grass yield was 150t/hm2,which quality was fine.Minmu42 fat content was 3.73%.Protein 9.58%.Fiber 40.73%.Ash content 7.63%.Ca 0.82%.P 0.36%.It was a good quality and high yield forage plant which adapts growing in the south of GuiZhou.
