白兰瓜(Honeydew)露地栽培改为塑料薄膜沟棚种植后,蔓枯病[Mycosphaerella melonis(Pass.)Chiu & walker]由原来的5月下旬发生,提前到5月上旬,高峰期由原来的6月上旬提前到5月下旬。高峰期由原来的6月上旬提前到5月下旬。蔓枯病的流行取决于5月下旬病害高峰期的降雨天数和降雨量。采用70％,代森锰锌500倍液三叶期灌根、开花初期灌根结合喷洒、座果初期喷洒能够有效的控制蔓枯病的流行。 Mycosphaerella melonis (Pass.) Chiu & walker from the open field planting of Honeydew to the plastic film gutter increased from late May to early May, with the peak from 6 Early in early May to late May. The peak period from the early June early to late May. The prevalence of gummy blight depends on the number of rainfall days and rainfall at the peak of the disease in late May. Using 70%, mancozeb 500 times the three-leaf stage irrigation, irrigation and irrigation at the initial flowering combined with fruit early spraying can effectively control the prevalence of vine disease.
