试验结果表明 ,利用太阳辐射热能可以确保保护地黄瓜不受霜霉病损害。在有效的且对黄瓜无伤害的高温生态控制条件下持续 2h ,即可收到基本杀灭叶表里病原体的理想防病效果。试验确定 ,以控温幅 4 6℃～ 4 9℃为佳。
Test results show that the use of solar radiation heat can protect the cucumber from downy mildew damage. In the effective and cucumber harmless high-temperature ecological control conditions for 2h, you can receive the basic anti-disease effect of the leaf surface to kill pathogens. Test to determine the temperature range of 46 ℃ ~ 49 ℃ better.
