| 摘要: |
| 本试验研究了药液酸碱度对粉锈宁和灭草喹在蚕豆叶面吸收率的影响。结果表明:①药液酸碱度对粉锈宁的吸收影响不大。②药液 pH 值可以显著地影响蚕豆叶片对灭草喹的吸收:pH 越小,吸收率越高。因而对于弱酸性农药,在作物能够忍受并且药剂本身也稳定的 pH 范围内,使用偏酸的药液可望达到提高其吸收率的目的。 |

| Abstract: |
| The influence of the pH of solution on the foliar absorption of triadimefon and imazaquin was investigated.It is shown that the pH of solution has no significant effect on the absorption of triadimefon.On the contrary,it can affect considerably the absorption of i- mazaquin:the lower the pH.the higher the rate of absorption.Therefore,it is possible to im- prove the absorption of such weak-acid pesticides by adjusting the pH of their spray solu- tions. |
| Key words: triadimefon imazaquin pH of solution absorption rate |
