不同灌溉施肥方式对樱桃番茄产量和品质的影响

目的]研究樱桃番茄在滴灌栽培时氮肥的合理施用量。方法]研究了不同灌溉与施肥处理对樱桃番茄产量和品质的影响。结果]樱桃番茄在滴灌栽培时,比常规畦灌栽培条件下生长发育更好,能提高肥料利用率。达到同样产量时,滴灌栽培能节省氮肥18.75%;产量随着氮肥的增加而增加,达到一定用量后由于植株营养生长过剩,产量反而下降。结论]滴灌栽培合理适用氮肥时,可以提高果实品质。

Effects of Different Treatments of Irrigation and Fertilization on Yield and Quality of Cherry Tomato

Objective]Reasonable application rate of nitrogenous fertilizer for cherry tomato in drip irrigation was studied.Method] Effects on the yield and the quality of cherry tomato were studied with different treatments of the irrigation and the fertilization.Result] Cherry tomato of drip irrigation grew and developed better than that of tradition border irrigation.Drip irrigation increased cherry tomato's water fertilizer utilization efficiency,and it decreased the application of nitrogenous fertilizer by 18.75% when the yield was as same as tradition border irrigation.With the application of nitrogenous fertilizer increasing,the yield of cherry tomato kept upward,nevertheless,beyond a certain level,the yield would fall down because of excessive vegetative growth.Conclusion] If nitrogenous fertilizer was used reasonably,drip irrigation could improve fruit quality.
