以四季小白菜为材料，采用盆栽试验用海藻生根剂对白菜苗进行灌根处理，通过测量不同处理对小白菜的株高、叶面积、干重等生长指标和光合速率、硝酸还原酶的活性、根系活力等生理指标研究海藻生根剂对四季小白菜生长的影响。结果表明：海藻生根剂成品500倍液处理四季小白菜可以增加白菜苗的株高、叶面积以及提高四季小白菜苗的光合作用，从而提高产量；且明显提高小白菜叶片中硝酸还原酶的活性和根系活力。而不加海藻提取液的生根剂半成品作用不明显。可见，海藻生根剂500倍液处理为最优浓度处理。

In this study,The four seasons cabbage was acted as experimental material,with different concentrations of seaweed rooting agent for root-irrigation in pot experiment.By measuring the growth indicators,such as plant height,leaf area,dry weight and photosynthetic rate,nitrate reductase activity and root activity to study the effect of seaweed rooting agent on four seasons cabbage.The results showed that rooting powder seaweed 500× could increase plant height,leaf area,and improve seedlings photosynthesis,thereby increased weight;and also significantly improved leaves’ nitrate reductase activity and root activity.Oppositely ,the effect of rooting agent without seaweed extration on four seasons cabbage was not significant. Under the experimental conditions,the optimal concentration was rooting powder seaweed 500×.
