1、糯玉米種植密度試驗研究摘要：本試驗在傳統(tǒng)密度種植試驗基礎(chǔ)上，進一步改善試驗方法，利用每一行相鄰兩顆玉米間的株距成等差數(shù)列的種植方案來設(shè)計雙因素試驗。主處理：每品種3mx8m的一個試驗區(qū)分為：2585/6670?、2925/6670?、3369/6670?、3970/6670?、5614/667m2的五個密度區(qū)來討論。副處理：種8個品種。經(jīng)分析8個品種，在這五個密度區(qū)域的葉片數(shù)、株高、穗位、莖粗等農(nóng)藝性狀和產(chǎn)量來研究密度、品種及密度與密度間的互作關(guān)系對各類性狀的影響。結(jié)果表明：密度對莖粗的影響達到了極顯著水平；密度對鮮重、穗長的影響，在0.05水平下表
2、現(xiàn)為顯著；晶種間的差異對各類性狀的影響也達到了極顯著水平；密度與品種間的互作關(guān)系只對葉片數(shù)的彩響表現(xiàn)為極顯著水平。通過相關(guān)數(shù)據(jù)分析得出：彩糯(自繁)，彩糯(海南)，銀糯2號(J11XY10)，銀糯2號(Y10XJ11)，銀糯1號,京糯2000,甜加糯，超甜等的適宜密度分別為:2850/667m2,3970/667m2,4500/667m2,3900/667m2,4970/667m2,3750/667m2,2980/667m2,3050/667m2。關(guān)鍵詞：糯玉米；種植密度；農(nóng)藝性狀。WaxymaizeplantingexperimentAbstrac
