In order to understand the adaptability of Guitang 42,sugarcane fields with different fertility were observed for many years by multi point test. The result showed that Guitang 42 have good performance in different soil fertility of Jinguang farm. The average yield of newly plant was the same with the control,but the yield of ratoon had larger scale increase than the control.The yield was increased with the increasing of ratoon year. More prominent on land with higher fertility. It is indicated that Guitang 42 was suitable for planting in the same type of sugarcane planting areas.%为了解桂糖42号的适应性,在金光农场蔗区选择肥力不同的蔗地,进行了多年、 多点的观察试验.试验结果表明,桂糖42号在金光农场蔗区不同肥力地块种植均表现出良好的适应性.与对照相比,虽然新植蔗的产蔗量与对照相当,但其宿根蔗的平均产蔗量增产显著,且宿根年限越长,增产越显著,这种优势尤其在高肥力地块中表现更突出.综上认为,桂糖42号较广西蔗区主栽品种而言更适合在相同蔗区种植.
