早熟马铃薯早大白施用钾肥增产效果研究

Test on Increasing Yield Effection of Early Cropping Potato Zaodabai Applied K Fertilzers

增施钾肥是早熟马铃薯一项重要的增产作措施,试验结果表明,早熟马铃薯早大白施氧化钾90kg·hm-2增产效果显著,较对照增产13552.5kg·hm-2,增产率57.9%;大中薯率较对照提高16.5个百分点。

It is one of important measures for early cropping potato Zaodabai yield with K fertilizer. Test results showed, output with 90 kg·hm^(-2)K2O fertilizer were more 57.9% than ck,Commodity percentage of big-middle was increased 16.5% than ck.
