微量元素对瓜类作物抗疫病能力的影响试验结果表明，微量元素对疫病菌的抑菌效果为Ｂ＞Ｃｕ＞Ｆｅ＞Ｚｎ＞Ｍｎ；营养液中Ｂ、Ｃｕ、Ｆｅ的浓度对黄瓜疫病病情影响较大，Ｚｎ、Ｍｎ的浓度对疫病病情影响不大；在缺硼土壤上增施硼肥，可以较好地提高节瓜的产量，并在一定程度上降低疫病的病情
Effects of trace elements on the resistance to diseases in cucumber The results showed that the bacteriostatic effect of trace elements on the pathogenic fungi was B> Cu> Fe> Zn> Mn. The effect of B, Cu and Fe in nutrient solution on the disease severity of cucumber The concentration of Zn and Mn had little effect on the disease severity. Adding boron fertilizer to boron-deficient soil could improve the yield of cucumber and reduce the disease’s disease to a certain extent
