不同施肥处理对马铃薯品种大西洋产量及干物质含量的影响

Effects of Different Fertilizers on the Yield and Dry Matter Content of Potato Cultivar Atlantic

为通过有效施肥调节马铃薯产量和品质,以马铃薯主食化主要加工品种大西洋为研究对象,采用两因素(底肥与追肥的不同肥料)随机区组试验设计,研究了不同肥料对马铃薯产量、干物质含量及全粉产量的影响。结果表明:单施底肥时,底肥施用硝酸钾对产量增加有显著影响,底肥施用硫酸钾对干物质含量有显著影响。两因素互作,底肥施用硝酸钾和叶面喷施锌肥对产量、干物质含量及全粉产量的增加具有显著作用。锌肥叶面喷施和底肥施用硫酸钾对干物质含量的提高有显著作用。综合判定,底肥施用硝酸钾和喷施锌肥对产量、干物质含量和全粉产量提升具有显著作用。

In order to regulate the yield and quality of potatoes by effective fertilization,a randomized block experiment was conducted to study the effects of different fertilizers on the yield,dry matter content and total flour yield of potatoes in Atlantic,the main grain processing variety of potatoes.The results showed that the application of potassium nitrate in bottom fertilizer had a significant effect on yield increase,and potassium sulfate in bottom fertilizer had a significant effect on dry matter content.The interaction of the two factors showed that potassium nitrate and zinc fertilizer had significant effects on the yield,dry matter content and total powder yield.Spraying zinc fertilizer on the leaf surface and applying potassium sulfate on the base fertilizer had significant effects on the increase of dry matter content.Comprehensive judgment showed that the application of potassium nitrate and zinc fertilizer in base fertilizer had significant effect on the increase of yield,dry matter content and yield of whole potato flour.
