    Irrigation Scheduling of Tomato by Subsurface Irrigation With Porous Pipe in Greenhouse

      摘要
    • 摘要: 通过对大棚番茄栽培渗灌灌水试验,从土壤水分含量、作物长势及果实产量、灌水次数及灌水量几方面进行分析研究,得出在渗灌管埋深30cm和灌水上限土壤水吸力值设定为6kPa时,其灌水下限土壤水吸力值在苗期可控制在25kPa,在开花-果实膨大期可控制在25～40kPa,而每次灌水量以0.93m3/hm2左右时,水分生产效率和番茄的产量均较高

       

      Abstract: Experiments of subsurface irrigation with porous pipe with different soil water lower limits for irrigation was conducted in greenhouse cultivated with tomato, and the results showed that the optimal soil water lower limit for subsurface irrigation with porous pipe was 25～40 kPa. The soil water lower limit for subsurface irrigation with porous pipe is 25 kPa during seedling stage, 25～40 kPa during flowering and fruit bearing stage, and the corresponding applied water is about 0.93 m3/hm2.
