为获得详实数据，指导贵州冬作马铃薯合理施肥，研究不同肥料、组合及不同施肥方式对冬作马铃薯产量、商品薯率及经济效益的影响。结果表明：追施不同肥料对冬作马铃薯产量、商品薯率均影响显著；施肥方式对商品薯率影响显著。施肥效果最优的处理为K2 SO4＋（ NH2）2 CO和KCl＋（ NH2）2 CO的对水处理；其产值、纯收入和较对照增收比例分别为48490．5元/hm2、21378．0元/hm2、120．2％和45750．0元/hm2、18997．5元/hm2、95．7％，增产增效作用显著，可在冬作马铃薯中进行适当面积推广应用，进一步验证。

In order to obtain detailed data to guide the rational application of fertilizers, we studied the effects of different fertil-izers, fertilizer combinations, and various fertilization modes on the yield, tradable potato rate and economic benefit of winter potato production in Guizhou.The results showed that:applying different kinds of fertilizers had obvious influences on the yield and trad-able potato rate of winter potato; fertilization mode had significant influence on the tradable potato rate.After applying K2 SO4 +( NH2 ) 2 CO+water or KCl+( NH2 ) 2 CO+water, better effects were acquired, and the output value, net income, and income-increasing (in comparison with the control) percentage of winter potato production were 48490.5 yuan/hm2, 21378.0 yuan/hm2, 120.2% or 45750.0 yuan/hm2, 18997.5 yuan/hm2, 95.7% respectively.Thus, K2SO4 +(NH2)2CO and KCl +(NH2)2CO could be properly popularized, utilized and further verified in the production of winter potato in Guizhou.
