| 摘 要： | 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K2SO4+(NH2)2CO和KCl+(NH2)2CO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。

| Abstract: | In order to obtain detailed data to guide the rational application of fertilizers, we studied the effects of different fertilizers, 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 tradable potato rate of winter potato; fertilization mode had significant influence on the tradable potato rate. After applying K2SO4 ＋ （NH2 ）2CO＋ water or KCl＋ （NH2）2CO ＋ 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/hm^2,21378.0 yuan/hm^2 ,120.2% or 45750.0 yuan/hm^2, 18997.5 yuan/hm^2, 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. |
