摘要：

摘要 采用盆栽实验研究结果表明，植物病害防治剂（兰迪多邦）不同浓度的处理均能促进黄瓜幼苗的生长，尤以150倍效果最佳，根长、株高、幼苗鲜重和干重都达到最大值。田间试验表明，施用兰迪多邦能显著增加黄瓜植株高度和使茎杆增粗，增大叶片面积，提高光合效率，延长绿叶功能；促进作物生长。对黄瓜霜霉病的防治，兰迪多邦100、150、200倍液与常用防治剂和清水对照相比都达到了显著、极显著差异，有效防治了霜霉病，以150倍液效果为最佳。

Abstract:

Abstract　 The pots experiment results showed that the plant diseases control agent (Randy multi-state) with different concentrations of treatment can promote the growth of cucumber seedlings, especially in 150 fold the best results, root length, plant height, seedling fresh weight and dry weight were reached the maximum. Field trails showed that application of Randy multi-state could significantly increase the plant height of cucumber and make thicker stems, increase the leaf area and photosynthetic efficiency, extend green leaf function; to promote plant growth. Prevention and control of cucumber downy mildew, The relative control efficacy of 100 fold and 150 fold and 200 fold Randy multi-state was more significant than that of other chemical drugs and water, the 150 fold of effect of Best.
