Abstract

The effects of external factors such as temperature, humidity, pesticide formulation, and pesticide concentration on the contact angle of pesticide droplets on rice leaf surfaces were analyzed. The experiments showed that there were significant differences in the contact angles of droplets on the leaf surfaces under different temperatures and humidity. As the ambient temperature increased, the contact angle first decreased and then increased, reaching a minimum value at 25°C. With a gradual increase in humidity, the contact angle significantly increased and reached a maximum at 100% humidity. Finally, it was concluded that both the formulation and concentration of the pesticide had a significant effect on the contact angle of droplets on rice leaf surfaces. The experiments also illustrated that the effects of the pesticide formulation and concentration on the contact angle were more significant than those of temperature and humidity.

温度和湿度对水稻叶片表面农药滴接触角的影响。
分析了温度、湿度、农药配方、农药浓度等外界因素对水稻叶片表面农药液滴接触角的影响。实验表明,不同温度和湿度条件下,液滴在叶片表面的接触角存在显著差异。随着环境温度的升高,接触角先减小后增大,在25℃时达到最小值。随着湿度的逐渐增大,接触角显著增大,在100%湿度时达到最大值。最后得出结论,农药配方和浓度对水稻叶片表面雾滴接触角有显著影响。实验还表明,农药配方和浓度对接触角的影响比对温度和湿度的影响更为显著。
