甘蔗的饲用栽培价值评价

以象草为对照,对9份甘蔗材料进行了研究.结果表明:营养期多次刈割利用模式下,甘蔗的再生性、干物质产量显著低于象草.部分甘蔗资源的抗寒性强于象草.甘蔗幼嫩期营养价值差,成熟期优于象草,比象草更适于一次性刈割利用.甘蔗不同材料在早期生长、分蘖、再生性、耐寒性及干物质产量等方面存在一定差异.

The feeding value of Saccharum officinarum cultivation

Nine sugarcane materials have been studied, with elephant grass as check plant. The results show that mowing in vegetative period will make the regeneration and DM yield of sugarcane obviously lower than elephant grass. The frost resistance of some sugarcane materials is superior to elephant grass. Because of the lower food value of sugarcane in vegetative period, but better than that of elephant grass in mature period, it is more suitable for mowing in mature period than that in vegetative compared with elephant grass. Among different materials of sugarcane, there are some difference existed in the early growing rate, tilling ability, regeneration, frost resistance and DM yield.
