Abstract：
By taking biological dye ponceau-G as tracer, the colorimetric method was adopted to analyze the effect of solution surface tension and spray methods on deposition rate of droplets on rice plants. The critical surface tensions of rice leaves at the tillering, booting and flowering stages were 34.46, 34.36 and 34.33 mN/m, respectively. Contrasting with only spraying clean water, the increase of deposition rate of ponceau-G on single rice plant varied among the three growth stages after spraying the ponceau-G solution supplemental with 100 mg/L TX-10 on rice plants. The deposition rate by top spray method with a manual sprayer increased by 80.85%, 29.80% and 22.61%, respectively. And the deposition rate by tilting spray method with a mist sprayer increased by 50.83%, 18.48% and 31.07%, respectively. By spraying the solution with same surface tension on the plants at the same stages, the deposition rate of ponceau-G on single rice plant by tilting spray method with a mist sprayer was much higher than that by drifting spray method with a mist sprayer and by top spray method with a manual sprayer. It will help to increase the deposition rate of droplet on rice plants to adopt mist sprayer and surfactant which may reduce the surface tension of solution for spraying pesticide in paddy fields.
