| 摘 要： | 为解决旱坡地甘蔗栽培水土流失和增产问题,于2007—2009年进行了黔糖4号坡地种植土壤免耕和常规开垦栽培(CK)试验与示范。结果表明:旱坡地土壤免耕栽培具有保水保土保肥和明显的增产效果。新宿平均产量129.21t/hm2,比CK增产12.95%,示范10hm2加权平均产量102.75t/hm2,辐射带动推广2 000hm2加权平均产量85.04t/hm2,示范推广2 010hm2加权平均产量93.90t/hm2,分别比CK增产13.0%、14.1%和13.5%;甘蔗种植+加工纯收入36 336元/hm2,产投比为1.79,分别比CK增加41.2%和0.23。种植业中土壤免耕栽培比CK减少投入土地开垦费1 800元/hm2,甘蔗纯收入增加10 579元/hm2,合计增收12 397元/hm2,效益明显。该结果对旱坡地甘蔗栽培控制水土流失、增收节支、提高种植效益具有一定的借鉴作用。

| Abstract: | Qiantang 4,a sugarcane variety,was planted in the sloping upland by no-tillage and conventional cultivation patterns respectively to solve soil erosion of sloping uplands and increase sugarcane yield.The results showed that the no-tillage cultivation pattern had the advantages of water,soil and fertility retention capacity and yield increase.The weighted average yield under the no-tillage cultivation pattern was 129.21t/hm2,11.7% higher than CK.The weighted average yield under the no-tillage cultivation pat... |
