水肥管理对有机番茄产量与番茄红素含量的影响

Effect of Different Water and Organic Fertilizer Management on the Yield of Organic Tomato and Contents of Lycopene in Organic Tomato

以番茄为试材,通过以灌溉量为主因素、施肥量为副因素的裂区设计,在北京郊区的日光温室中进行田间试验,为了解在有机种植模式中不同水和有机肥耦合条件下番茄产量及其对番茄红素含量的影响。结果表明:与当地习惯的水肥管理相比,减半量有机肥投入在产量上无显著下降,同时可增加番茄果实中番茄红素含量以及相同面积内番茄红素总量;与在施肥量相同的条件下,减量灌溉对增加番茄红素含量无显著影响,效果没有减量施肥效果明显。试验结果表明,在京郊有机番茄的种植中,保证产量和品质的前提下开展节本增效仍有很大空间。

Taking tomato as material, using the split-plot design of the main factors in irrigation and the second factor in organic fertilizer,under organic planting in sunlight greenhouse in suburb of Beijing,China. Effect of different water and organic fertilizer managements on yield of tomatoes and contents of lycopene in organic tomato were studied. The results showed that compared with local farmers＇ conventional management of water and fertilizer, the half amount of organic fertilizer inputs would not significantly decrease the yield of tomato, furthermore increasing the content of lycopene in the same area as well as the total amount of lycopene in tomato fruit. Under the same conditions as fertilizer, irrigation reduction had no significant effect on the increase in lycopene content. The dfect was not as significant reduction of fertilization. It was concluded that there was a great potential to reduce the application of water and organic fertilizer under the current condition of overdose of organic fertilizer.
