摘要
通过同田对比试验研究了不同钾肥用量和品种对冬作区马铃薯产量、品质的影响,以期为贵州冬作区马铃薯专用肥生产以及应用提供理论资料。结果表明:贵州省土壤肥料研究所多年研究的冬作区马铃薯专用肥配方(N∶P2O5∶K2O=10∶12∶16)适宜在贵州冬作区马铃薯生产中应用,亦可以用氯化钾替代硫酸钾,以降低马铃薯专用肥的成本。
The effects of different amount of potassium fertilizer and varieties on potato yield and quality in winter were studied by the same field contrast experiment. The results showed that the (N : P2O5 : K2O=10 : 12 : 16) in Guizhou province was suitable for potato production, other fertilization method of KC1 intead of K2 SO4, and it can be used in the production of potato in Guizhou.
