【摘要】 试验采用不同浓度(25%,50%,75%,100%)的沼液对设施番茄进行滴灌施肥,探讨施用沼液对番茄生长、产量和品质的影响。结果表明,与清水对照相比,施用沼液可促进番茄生长、提高产量和改善品质;当沼液体积分数为50%时,番茄的株高、茎粗和果实直径较大,分别达132.3,2.53,7.81 cm,较对照分别高出21.94%,50.60%,29.30%;产量较高,达92.79 t/hm2,较对照增产29.00%;且番茄红素、可溶性糖、糖酸比、Vc含量等品质指标也较佳。因此,灌溉体积分数为50%的沼液对提高设施番茄产量、改善品质以及促进绿色无公害蔬菜种植具有重要意义。更多还原

【Abstract】 In order to investigate the effect of biogas slurry on growth, yield and quality of tomato, experiments with different concentration(25%, 50%, 75% and 100%)of drip irrigation with biogas slurry on tomato were carried out. The results showed that compared with water treatment(control), drip irrigation with biogas slurry could increase the tomato growth, yield and quality. When biogas slurry concentration was 50%, the plant height, stem and fruit diameter of tomato were 132.3, 2.53, 7.81 cm, respectively, which were 21.94%, 50.60%,29.30% higher than the control treatment, and the yield was 92.79 t/hm2, which was 29.0% higher than the control treatment. Under this concentration, tomato lycopene, soluble sugar, sugar acid ratio, Vc content were also the best. The comprehensive analysis suggested that the optimum biogas slurry concentration is 50%. It is of great significance to improve tomato yield and quality,and promote green and pollution-free vegetable planting.更多还原
