Abstract:

With tomato as materials，the method to inhibit the green algae in the nutrient solution in the negative pressure device were studied，different concentrations of H₂O₂ were added in the nutrient solution (control，shading，0.1% H₂O₂，0.3% H₂O₂，0.5% H₂O₂ and 0.7% H₂O₂) to investigate the impact of treatments on green algae in the nutrient solution and tomato production.The aim was to find new way to inhibit green algae in the nutrient solution，and ensure tomato production smoothly using negative pressure device supplying nutrient solution.The results showed that existence of green algae would bring negative effects on the growth，yield and quality of tomato.Shading and H₂O₂ treatment could inhibit green algae，thereby avoiding negative effect brought by green algae-to reduce growth and yield of tomato.0.3% H₂O₂ treatment did not affect tomato yield；0.5% and 0.7% H₂O₂ treatments lead to reduction of tomato yield；low concentration (0.1%，0.3%) treated with H₂O₂ will generate some negative effects on the quality of tomato.However，low concentration (0.1%，0.3%) treatment would not affect the growth of tomato.0.5% and 0.7% H₂O₂ treatments would affect tomato growth.
