韭菜干尖症防治试验

以广州市白云区江高镇蓼江村韭菜为试材,研究了不同防治方法对韭菜干尖症的影响,以期减轻韭菜干尖症,提高蓼江村夏季韭菜的品质和产量。结果表明:土壤氮元素含量偏低、钾元素运转阻碍、生长期过长等是造成韭菜干尖症的主要原因。通过适时利用遮阳网并增施叶面肥、适当调整收割间隔期等措施可有效减轻韭菜夏季干尖症,并提高产量。

Control experiment on the tip-dry disease of leek

In order to relieve the tip-dry disease and improve the quality and yield of leeks of Liaojiang village in summer,influence on tip-dry disease by different control methods were investigated in this study using leeks of Miujiang village as experimental material.The result showed that:the low soil nitrogen content,block on potassium transportation and too long of the grow stage were the main cause of the tip-dry disease.Timely using the shade net,increasing the fertilizer and regulating the harvest time on leek will effectively relieve the tip-dry disease and enhance the yield of leeks.
