微喷灌施药防治花生疮痂病的经济效益分析

Economic Benefit Analysis on the Fungicides Control of Peanut Scab by Micro-spray Irrigation System

[目的]为提高灌溉条件下水药一体化程度、降低喷药人工成本。[方法]通过大田试验,采用微喷灌溉系统施药筛选花生疮痂病防治的有效药剂及其防治经济效益。[结果]试验筛选的5种药剂均有一定的防治效果,以60%百泰水分散粒剂、爱苗乳油、秀特乳油防治效果较好,3种药剂处理的差异不显著(P<0.05),其中以爱苗的防效最高,达到了75.4%,3种药剂的增产幅度分别达到15.5%、16.7%和13.4%,喷施爱苗、百泰和秀特的亩增加纯效益分别为3 978、3 714和3 162元/hm2。[结论]较之传统化学药剂与传统人工喷施方法,借助灌溉系统随水喷施药剂可实现花生水药一体化和增产增效。

[Objective] The aim was to improve the level of water-pesticide integration and decrease the cost of manual spraying. [Method] Through the field trial, the effective fungicides for peanut scab by micro-spray irrigation system were screened and its control benefits were summarized. [Result] The results showed that five fungicides had control effects in a certain. 60% Baitai （WG）, Armure and benzoic propiconazole had better effects than others, but had no difference between treatments （P〉0.05）. Spraying Armure was the best and its control effect was 75.4%. The improved yields of Baitai, Armure 13.4%, respectively. And economic benefits were 3 978, and benzoic propiconazole were 15.5%, 16.7% and 3 714 and 3 162 yuan/hm^2. [Conclusion] Compared with the conventional fungicides and manual spray method, irrigation systerm and sparying pesticide could implement waterpesticide integration and increase production and efficiency.
