[目的]对“易丰收”植物生长调节剂在保护地番茄上的应用效果进行研究。[方法]设浓度梯度分别为0、4.5、7.5、12.0 mL/hm2 4个处理组进行施用效果比较。[结果“]易丰收”处理组与对照相比在果实直径、单果重、单位面积产量、含糖量、果实硬度均有明显提高,其中浓度梯度为7.5、12.0 mL/hm2的2个处理与对照的差异均达到显著水平。[结论]施用“易丰收”能够显著提高保护地番茄的产量并改善果实品质。 [Objective] The research aimed to study the application effect of “Yi Feng Shou” plant growth regulators on tomato in protected area. [Method] To compare the effect of four different treatment groups with 0, 4.5, 7.5 and 12.0 mL / hm2 concentration gradient respectively. The results showed that there was a significant increase in fruit diameter, fruit weight, yield per unit area, sugar content and fruit firmness compared with the control group, of which, the concentration gradient was 7.5,12.0 mL / hm2 The difference between treatment and control reached significant level. [Conclusion] Applying “Yi Feng Shou” can significantly increase the yield of tomato in protected area and improve the fruit quality.
