摘　　要：对安阳市不同土壤钾素水平的玉米田块进行钾肥试验 ,结果表明 ,施钾能不同程度地增加安阳市夏玉米的株高和产量 .在低钾土壤上 (速效钾 <12 0mg·kg-1)施用钾肥增产效果明显 ;在高钾土壤上 (速效钾 >15 0mg·kg-1)Experiments were conducted on the effect of potassium fertilizer application in different contents of potassium nutrient in the maize field.The results showed that application of potassium fertilizer could increase the plant height and yield of summer maize to a certain extent,and the yield increasing effect of potassium fertilizer application on soil of lower content of potassium was significant,while that on soil of higher content of potassium was not significant.
