摘　　要：为了发挥黔糖4号高产高糖的效果,借鉴甘蔗吨糖田土研究成果,于2007-2009年进行了该品种吨糖田土试验、示范及推广应用。结果表明:坝地和坡地试验新宿平均产量134.45t/hm2和产糖量18.09t/hm2,比对照增加50.76%和66.88%,坝坡地新宿平均667m2产糖量为1.206t和1.106t,产糖量达1t以上;坝、坡地示范新宿加权平均产量119.29t/hm2,产糖量16.00t/hm2,比对照增加53.66%和70.76%,坝坡地新宿667m2加权平均产糖量1.08t和1.04t,产糖量均达1t糖以上;坝坡地平均纯收入40 602元/hm2,比对照高43.61%。结论:吨糖田土技术应用是提高黔糖4号产量和产糖量、增加效益的有效途径。Qiantang 4,a new sugarcane variety with high yield and sugar yield,was tested,demonstrated and popularized to probe the integrated cultivation technology for 1000kg sugar yield/667m2 based on the previous research achievements.The results showed that in the plot test,the average yield and sugar yield of Qiantang 4 planted in flat and slope field was 134.45t/hm2 and 18.09t/hm2,50.76% and 66.88% higher than CK and the average sugar yield of Qiantang 4 planted in flat field and slope field reached 1.206t/667m2 and 1.106t/667m2 respectively.In the demonstration test,the average yield and sugar yield of Qiantang 4 planted in flat and slope field was 119.29t/hm2 and 16.00t/hm2,53.66% and 70.76% higher than CK.And the average sugar yield of Qiantang 4 planted in flat field and slope field could reached 1.08t/667m2 and 1.04t/667m2.The average net income of Qiantang 4 plated in flat and slope field was up to 40,602 Yuan/hm2,43.61% higher than CK.Therefore,the integrated cultivation technology could increase yield,sugar yield and economic benefit of Qiantang 4.
