乙蒜素对款冬花保苗效果的研究

Study on Effect of Etnylicin on Keeping Seedling of Tussilago farfarae L.

[目的]研究不同浓度乙蒜素处理对款冬花的保苗效果。[方法]采用低(3 000倍)、中(2 000倍)、高(1 000倍)乙蒜素处理本地款冬花种茎;用高浓度乙蒜素处理异地种茎;并比较不同灌根和喷雾处理对保苗效果的影响。[结果]播种前用低浓度乙蒜素处理本地种茎效果较好,起到一定的保苗效果;异地调种具有一定的保苗效果;生长发病初期用中浓度乙蒜素灌根效果较好,且叶面喷雾和灌根效果无明显差别。[结论]乙蒜素处理对款冬花具有一定的保苗效果,生产中建议使用叶面喷雾法。

[ Objective] To study keeping seedling effect of etnylicin under different concentration on Tussilago farfarae L.. [ Method] The local Tussilago farfarae L. stems were treated with low concentration （3 000 times）, middle concentration （2 000 times） and high concentration （ 1 000 times） etnylicin,individually, and the ecdemic Tussilago farfarae L. stems were treated with high concentration etnylicin. Effects of different trea- ting methods like root pouring and foliar spraying were comparatively studied. [ Result] Befnre sowing, Tussilagofarfarae L. treated with low con- centration etnylicin was better in keeping seedling and ecdemic Tussilago farfarae L. showed better seedling rate. At early period of disease, Tussil- ago farfarae L. treated with middle concentration etnylicin using both root pouring and foliar spraying grew better. [ Conclusion] Etnylicin showed keeping seedling effect on Tussilago farfarae L. ,and foliar spraving would be better.
