| 摘 要： | １９９７－１９９８年在高水肥地进行了钾肥用量试验研究，结果表明，含速效钾２４５ｍｇ．ｋｇ＾－１的土壤施钾增产不显著，含速效钾２０９ｍｇ．ｋｇ＾－１的土壤施钾达到了显著的增产效果。施钾后，小麦植株干重，吸钾强度，吸钾数量明显提高。适宜施肥量（Ｋ２Ｏ）７．５－１０ｋｇ／６６７ｍ＾２，增产幅度１８％－２５％。

| Abstract: | The study of the applied amount of potassium fertilizer in winter wheat was investigated under high fertility fields. The results showed that the K applied could increase the dry weight, K absorption rate and capacity of wheat plants. The increased yields were not markedly different in K applied than in control under 245mg/kg level of rapidly availablc potassium, but were sikniificantly higher in K applied than in control under 209mg/kg level of rapidly available potassium. The optimum amount of potassium fertilizer appied was 7. 5~ 10kg/667m2,and the grain yield increased by 18 % ~ 25 %. |
