【摘要】 对从巴西引进的3个饲料蔗品种B9、B10、B60进行比较试验,结果表明:B60、B9品种具有较高的鲜茎叶产量,较强的发株能力和分蘖能力,水溶性总糖、粗蛋白质含量较高,适口性较好;在年收割2次的情况下B60的最佳下种量为15万芽/hm2,鲜茎叶产量最高,达到288.97t/hm2;青饲奶牛的产奶量以B60最高,接近GM1号象草;B60等品种可作为粗饲料的补充在广西推广种植。更多还原

【Abstract】 A comparative experiment for three fodder sugarcane varieties(B9,B10,B60) from Brazil shows that B60 and B9 have the higher fresh stem and leaf yield,stronger germinating and tiller ability,higher water-solubility total saccharide and crude protein and better taste.In two harvesting per year,B60’s best sowing density is 150,000 sprouts/ hm2,which can reach the highest fresh stem and leaf yield of 288.97 t/ hm2.The dairy cattle’s milking yield for B60 feeding is highest,similar to GM1 grassiness.The B9 etc can also be planted in Guangxi as a supplement of coarse fodder.更多还原
