【摘要】 引进29个甘蔗新品种(系)进行品种比较试验,通过新植蔗和宿根蔗各1年的试验结果表明:在坝地种植22 个品种,比对照F134增产14.2%~37.7%,蔗糖分含量增长1.20~2.85个百分点,理论产糖量增长30.7%~62.2%的有14 个品种;在旱坡地种植7个品种,比桂糖11号增产10.0%~26.4%,蔗糖分含量增长1.15~3.46个百分点,理论产糖量增长27.3%~39.9%的品种有4个。这18个品种是生长势旺、抗病虫性较强、抗逆性强、宿根性较好的高产高糖品种。更多还原

【Abstract】 Twenty-nine introduced sugarcane varieties were tested to investigate their yields and sugar contents.The results show that yields and sugar contents of 22 varieties planted in the flat ground are 14.2%～37.7% and 1.20%～2.85% higher than CK respectively and the theoretical sugar-producing amount of 14 varieties increase by 30.7%～62.2%. The yields of 7 varieties planted on upland sloping land increase by 10.0%～26.4% and sugar content raising 1.15%～3.46% than CK respectively and the theoretical sugar-producing amount of 4 varieties increases by 27.3%～39.9%. The 18 varieties showed vigorous growth, strong (disease)-resistance, adverse-resistance and good perennial root.更多还原
