| 摘 要： | 试验结果表明,樱桃番茄在滴灌栽培时,比常规畦灌栽培条件下生长发育得更好,能提高肥料利用率。在产量相同时,滴灌栽培能节省N肥18.75%;产量随着N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。滴灌栽培合理施用N肥时,可以提高果实的品质。

| Abstract: | 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. If nitrogenous fertilizer was used reasonably,drip irrigation can improve fruit quality. |
