摘　　要：通过大田试验和室内分析方法研究了潮土上两个超高产小麦品种吸钾能力、钾利用效率 ,初步研究结果表明 :两个超高产小麦品种在吸钾量、施钾效应、钾肥利用率、利用土壤钾素的能力以及钾效率等方面都存在着差异性 ,温麦 6号是一个耐低钾、钾营养高效基因型品种。We studied the abilities of absorbed K and K use efficiency between two super high yield wheat varieties in Chao soil. The initial research results showed: there were differences in aspects of K uptake, dressing K effect, K use efficiency,and K efficiency between two super high yield wheat varieties. Wenmai 6 was a low K tolerance and high K efficiency genotype variety.
