AbstractTo addressthe partial isues of low positioning eficiency，cumbersome operations，and data inaccuracies inconventional herbicideeficacyfield trials，thisstudydevelopedamultifunctional plot markertoenhance experimental standardization and scientific rigor.The device comprises a square frame，support legs，signage poles，and counting panels，withkey technical features including：an internal counting grid for sub-region division to minimize countingomissons;hinged support legsat four corners ensuring stability on complex terrain；telescopic sleeve structures for signage and counting poles alowing height adjustment acording to crop growth and foldable for compact storage，improving portability.Furthermore，hinged frame connectionsand folding mechanisms enable flexible shape adjustments toaccommodatediverse sampling requirements.This fixed-point devicecanshortenthe field operation time toacertain extent，improvetheaccuracyand portabilityofcounting，and hasrelatively high economicbenefits.The devicedesign buildson extensive field experience withsolid practical foundation;itenhances trial eficiencyand precision while being reusable with evident benefits;its applications extend beyond herbicide evaluation toagricultural pestand disease monitoring，fertilizer eficiency evaluation，and grassland resource surveys.This study provides a reference for the design and broader application of this multifunctional fixed-point device.

根據(jù)《農(nóng)藥田間藥效試驗準(zhǔn)則》，除草劑藥效試驗前期，須確定一個 的定點位，并進行15、30、45、60、120d的觀察與計數(shù)，這是確保除草劑藥效規(guī)范試驗順利進行的關(guān)鍵步驟。（剩余3822字）
