天津市農(nóng)業(yè)中心開(kāi)展2024年天津市小麥農(nóng)藥利用率測(cè)定試驗(yàn)

2024-06-12 09:50:34 來(lái)源：天津市農(nóng)業(yè)發(fā)展服務(wù)中心 閱讀量：12302 評(píng)論

導(dǎo)讀：近日，天津市農(nóng)業(yè)中心聯(lián)合中國(guó)農(nóng)科院植保所在我市武清區(qū)蘭家莊聯(lián)合開(kāi)展了小麥田農(nóng)藥利用率測(cè)定試驗(yàn)。

　　【農(nóng)機(jī)網(wǎng) 地方農(nóng)機(jī)】 為貫徹落實(shí)農(nóng)業(yè)農(nóng)村部《到2025年化學(xué)農(nóng)藥減量化行動(dòng)方案》文件精神，按照全國(guó)農(nóng)技中心印發(fā)的《做好2023—2025年農(nóng)藥使用監(jiān)測(cè)評(píng)估工作的通知》的安排部署，近日，市農(nóng)業(yè)中心聯(lián)合中國(guó)農(nóng)科院植保所在我市武清區(qū)蘭家莊聯(lián)合開(kāi)展了小麥田農(nóng)藥利用率測(cè)定試驗(yàn)。通過(guò)比較不同植保器械的噴霧方法在小麥田的霧滴沉積分布，研究添加助劑對(duì)藥劑沉降和防治效果的影響，為篩選高效施藥機(jī)械和科學(xué)施藥方法提供了科學(xué)依據(jù)。
 
　　本次試驗(yàn)共設(shè)置10個(gè)試驗(yàn)小區(qū)，選取我市常用5種主要施藥器械，包括T20、T50、T60植保無(wú)人機(jī)、背負(fù)式電動(dòng)噴霧器、自走式噴桿噴霧機(jī)，進(jìn)行試驗(yàn)。噴霧前在試驗(yàn)小區(qū)內(nèi)布置霧滴測(cè)試卡，通過(guò)不同植保器械實(shí)施作業(yè)，研究分析不同植保器械的作業(yè)效率，噴霧作業(yè)對(duì)作物損傷率、噴霧霧滴粒徑與噴霧霧滴在作物不同部位的沉積分布密度以及三種不同化學(xué)助劑霧滴沉積參數(shù)等內(nèi)容，同時(shí)，在藥劑減量的條件下，與常量用藥的效果進(jìn)行對(duì)比，明確桶混助劑及不同機(jī)械施藥對(duì)農(nóng)藥利用率和對(duì)小麥白粉病防治效果的影響，并開(kāi)展農(nóng)藥減量增效效果分析。
 
　　本次試驗(yàn)的開(kāi)展，將進(jìn)一步明確我市小麥農(nóng)藥利用率水平及植保機(jī)械應(yīng)用發(fā)展情況，為我市2024年農(nóng)藥利用率數(shù)據(jù)提供理論依據(jù)。
