【摘要】 利用盆栽试验研究了有机-无机复合肥料对番茄产量、品质和有关生理特性的影响。结果表明,与施用等NPK无机养分对照比较,施用复合肥料B可以提高根系活力和叶片硝酸还原酶(NR)活性,增产17.13％。同时提高果实维生素C和可溶性糖含量,降低果实有机酸含量,增加糖/酸比。施用复合肥料A2可以提高根系活力和叶片NR活性,增产16.3 3％,提高果实维生素C和可溶性糖含量,但有机酸含量增加,糖/酸比略有下降。施用复合肥料A1可以提高果实可溶性糖含量、增加糖/酸比,但有机酸含量增加,且果实维生素C含量和产量的增幅较小。更多还原

【Abstract】 A pot experiment was conducted to investigate the effects of organic-inorganic compound fertilizers on yield, quality and some related physiological characteristics in tomato. Results showed that application of organic-inorganic compound fertilizer B increased root activity, raised NR activity in leaf, and increased yield by 17.13%.At the same time, compound fertilizer B application raised the content of vitamin C and soluble sugar, decreased the content of organic acid, and raised the ratio of soluble sugar to organic acid in fruits. The application of organic-inorganic compound fertilizer A2 increased root activity, raised NR activity in leaf, and increased yield by 16.33%.At the same time, compound fertilizer A2 application increased the content of vitamin C, soluble sugar and organic acid in fruits,and decreased the ratio of soluble sugar to organic acid in fruits. The application of organic-inorganic compound fertilizer Aj increased the content of soluble sugar and organic acid, and raised the ratio of soluble sugar to organic acid in fruits. The increments of vitamin C content of fruits and fruit yield were little when fertilizer A, was applied.更多还原
