摘　　要：【目的】探索木薯节本增效栽培技术,为旱地木薯节本增效栽培提供参考。【方法】对比粉垄栽培与传统整地栽培(CK)两种种植方式对木薯品种新选4088的茎叶生长及产量构成因素的影响,并测定株高、茎径、单株叶片数、块根长度、块根直径、单株块根重和产量等。【结果】粉垄栽培的木薯块根长度、块根直径、单株块根数、单株块根重和鲜块根产量分别较对照增加了25.35%、28.70%、30.00%、44.92%和46.69%。【结论】粉垄栽培技术可促进木薯前中期茎叶生长,增加木薯生物量,提高木薯产量,是促进木薯产业可持续发展的一项重要措施。[Objective]The present study was conducted to explore a low cost-high benefit cultivation technique for cassava cultivation. [Method]Effect of two planting patterns, viz., ridge and traditional cultivation （CK） on growth and yield of cassava variety Xinxuan 4088 were observed by measuring plant height, stem diameter, length and diameter of tuber, number of tubers per plant, weight of tuber per plant and yield of tubers. [Result]The ridge cultivation technique improved stem and leaf growth of cassava at the early and middle growth stage and increase the biomass of cassava. The plants cultivated with ridge cultivation method showed 25.35, 28.70, 30.00, 44.92 and 46.69% increase in length, diameter, number of tubers per plant, weight of tubers per plant and yield of tubers, compared to CK. [Conclusion]The ridge cultivation technique enhanced the yield of cassava. The technique may be applied for commercial cassava production to ensure the supply of raw material in cassava processing enterprises and for sustainable development of cassava production.
