以番茄和豆角为试材,采用大棚番茄老株更新套种豆角栽培模式,研究了其对番茄的产量及产值的影响。结果表明:番茄老株更新后套种豆角与不套种豆角相比,番茄每667m2总产量减少了407kg,但差异不显著;豆角每667m2产量为723kg,每667m2总产值为20 695元,增加经济收入2 597元。说明番茄老株更新套种豆角栽培技术可提高经济产值和土地利用率。 Tomato and beans as the test material, the greenhouse old tomato plant was reformed interplanting bean cultivation mode to study its impact on tomato yield and output. The results showed that the total yield of tomato seedlings per 667m2 was reduced by 407kg, but the difference was insignificant. The yield per 667m2 of beans was 723kg, the total output value per 667m2 was 20 695 yuan, which increased the economic income 2 597 yuan. Explain that the old tomato strains of interplanting bean cultivation techniques can improve economic output and land utilization.
