摘　　要：为了探讨攀西地区冬作青薯9号节水节肥最佳栽培模式,以每667 m^2膜下滴灌160 m^3、140 m^3、120 m^3、100 m^3四个灌水量梯度和基施底肥100 kg、80 kg、60 kg三个施肥水平进行试验,研究其在不同水肥梯度下农艺经济性状及生产性能表现。结果表明,青薯9号出苗率与灌水量和底肥施用量影响较小;其他性状则表现为水肥条件越充足,生长量越大,产量越高;水分利用效率随灌水量的增加而降低。灌水量为140~160 m^3/667 m^2,底肥施用量80~100 kg/667 m^2,为攀西地区青薯9号水肥一体化高垄双行膜下滴灌高产栽培模式优选的灌水量和底肥施用量。In order to explore the optimal water-saving and fertilizer-saving cultivation mode of winter potato Qingshu 9 in Panxi area, the experiment was conducted by designing four irrigation gradients: 160 m^3, 140 m^3, 120 m^3 and 100 m^3, and three basal fertilizer levels: 100 kg, 80 kg and 60 kg per 667 m^2 to study its agro-economic traits and production performance under different water and fertilizer gradients. Results showed that irrigation amount and basal fertilizer amount had little influence on seedling emergence rate;sufficient water and fertilizer can improve growth and yield;water use efficiency decreased with the increase of irrigation amount. The optimum irrigation amount was 140~160 m^3/667 m^2, and basal fertilizer amount was 80~100 kg/667 m^2, which can increase the yield of winter potato Qingshu 9 under the conditions of water and fertilizer integration, high-ridge and double-row, drip irrigation under plastic mulch.
