土壤水分对土壤钾水平与玉米吸钾关系的影响Ｋ．Ｓａｒｄｉ，Ｐ．Ｆｕｌｏｐ玉米需Ｋ高峰往往发生在前期生长阶段的快速吸收期。Ｊｏｒｄａｎ等（１９５０）和Ａｒｎｏｎ（１９７５）研究表明，玉米抽雄前３周吸收的Ｋ占总吸Ｋ量的６０～６５％，出苗后３０天，Ｋ积累速率...
Effect of soil moisture on the relationship between potassium in soil and potassium uptake by maize. Sardi, P. Fulop maize requires a K-peak that occurs rapidly during the early growth phase. Studies by Jordan et al. (1950) and Arnon (1975) showed that K absorbed by maize three weeks before tasselling accounted for 60-65% of the total K uptake, and K accumulation rate was 30 days after emergence.
