摘要：

[摘要] 超敏蛋白是植物病原细菌产生的蛋白,可诱导植物的过敏性反应。本文研究了超敏蛋白处理诱导温室黄瓜抗病性，结果表明：黄瓜移栽后开始每间隔20d叶面喷施1次3%的超敏蛋白微粒剂10g-30g+水30kg/ 667㎡，共施用3次，对黄瓜霜霉病和灰霉病的诱抗效果分别高达58.90%和44.22%，不同超敏蛋白浓度间诱抗效果无显著差异。如果病害发生严重时，以3%的超敏蛋白微粒剂20g+水30kg/ 667㎡结合施放相应杀菌烟雾剂，防治效果更好，达80.26%。

Abstract:

Abstract: Harpins are proteins produced by plant pathogenic bacteria; They induce hypersensitive response in non-host plants. The the induce-resistance effect of Harpin was investigated in cucumber. The results show that the 3% HarpinEa 10g-30g + water 30kg / 667 ㎡Were applied 3 times 20 days interval after the cucumber transplanting. The effect of induced resistance on cucumber downy mildew and Botrytis cinerea were respectively up to 58.90% and 44.22%. The effect of different concentrations of HarpinEa had no significant difference. If the occurrence of these two diseases were serious，3% HarpinEa 20g + water 30kg / 667 ㎡combined with the corresponding aerosol released had a better effect and the effect was up to 80.26%.
