摘要: 对大棚番茄越夏长季节栽培的水肥量化管理指标进行了研究。结果表明,灌水量对番茄产量有很大影响,较高的灌水量可获得较高的产量和生物量,但水分生产效率和水分干物质生产率低于中水量处理。相同追肥情况下,灌水量的增加对叶片叶绿素含量和果实营养品质有稀释效应。从产量、水分利用率和成本等方面综合考虑,最适水肥管理指标为:土壤含水量为35%~45%(体积含水量),肥料组合为硫酸铵+硫酸钾或尿素+硫酸钾,且肥料养分中N:K2O=1:1.2。

Abstract: The experiment of different water and top fertilizer combination for tomato cultivated in greenhouse were studied in long season cultivation over summer.The results showed that water irrigation had significant effects on tomato yield.Higher water irrigation could attain higher yield and dry matter,but water produce efficiency and dry matter productivity in high water irrigation treatments were much lower than that in middle water irrigation treatments.With the same top dressing fertilizer mixture treatments,the contents of chlorophyll in leaves and nutrient qualities of fruit might diluted by more water.Considering yield,water using efficiency and cost,the best soil water content was 35%-45%(V/V),the economic and suitable top dressing fertilizer combinations were(NH4)2SO4+K2SO4 or CO(NH2)2+K2SO4,the proportion of N:K2O=1:1.2.

Key words: Tomato, Long season cultivation over summer, Water irrigation quantity, Fertilizer mix ratio
