- 摘要:
- 以番茄为试材，通过在营养液中添加不同浓度的双氧水H2O2（对照、遮光、0.1%H2O2、0.3%H2O2、0.5%H2O2、0.7%H2O2），研究其对营养液绿藻生成和番茄产量及品质的影响，寻求抑制负水头灌溉装置中营养液绿藻发生的新方法，以期保障负水头供营养液方式下番茄的顺利生产。结果表明：营养液绿藻的产生会给番茄的生长、产量和品质带来一定的负作用；物理遮光和H2O2可以抑制绿藻生成，进而避免绿藻带来的番茄生长减缓、产量降低等危害。0.3%H2O2处理对番茄产量无影响，0.5%、0.7% H2O2处理影响番茄的产量；低浓度（0.1%、0.3%）的H2O2处理对番茄的品质产生一定的负作用但对番茄的生长无影响，0.5%、0.7% H2O2处理影响番茄的长势。
- 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.
