| 摘 要： | 用RB72-454和F134(CK)2个甘蔗品种,于2003~2005年在坝地和缓坡地进行吨糖田土试验示范,经新植和宿根研究结果表明:在用种量8 000芽/667m2、深沟双行种植、合理施肥和优化管理技术规范下,RB72-454坝地蔗糖分含量15.47%,产量8 616 kg/667m2,产糖量1 130 kg/667m2,比对照蔗糖分含量增长1.16个百分点,产量增加38.0%,单位面积产糖量增加49.1%;坡地蔗糖分含量15.56%,产量7 808 kg/667m2,产糖量1 030 kg/667m2,比对照蔗糖分含量增长1.16个百分点,产量增加37.5%,单位面积产糖量增加48.3%。RB72-454在坝地和坡地含糖量均达到1 t/667m2以上。

| Abstract: | Two sugarcane varieties,RB72-454 and F134 (CK),were tested on the ground and flat gradient soils to find out the comprehensive cultivation techniques for over 1t/667m~2 of sugar yield.The results indicate that the cane sugar content,yield and sugar content of RB72-454 planted on ground soil are 15.47%,8616kg/667m~2 and 1130kg/667m~2,1.16%,38.0% and 49.1% higher than those of CK respectively,the cane sugar content,yield and sugar content of RB72-454 planted on flat gradient soil are 15.56%,7808kg/667m~2 and 1030kg/667m~2,(1.16%),(37.50%) and(48.3%) higher than those of CK separately. |
