【農機網 地方農機】 9月23日至9月25日，山東省農業機械技術推廣站副科長劉榮國一行4人在菏澤市牡丹區農業機械服務中心副主任郭愛英及工作人員的陪同下，對牡丹區承擔的2024年山東省夏玉米高性能播種作業質量對比監測試驗玉米單產提升試驗田進行了實收測產，高性能播種作業質量優勢明顯。
牡丹區設立的兩塊試驗田分別位于牡丹區何樓辦事處蘇淺村和牡丹區吳店鎮吳胡同村。玉米播種試驗采用勺輪式、指夾式和氣吸式三種形式
排種器的
玉米播種機，采用正常作業速度，每個試驗田設立三個試驗區，每個試驗區面積50畝，在水肥管理等其他條件相同的情況下，分別進行三種播種模式的對比監測。經過計算，氣吸式播種模式果穗重小于指夾式和勺輪式，氣吸式播種模式畝穗數大于指夾式和勺輪式，氣吸式播種模式標準畝產量與指夾式和勺輪式相比，增產率分別為11.99%，7.62%。
通過對比監測測產數據證明，氣吸式播種模式玉米產量明顯高于指夾式和勺輪式，為今后大力推廣應用玉米高性能氣吸式
播種機打下了理論基礎和實踐依據。
