摘　　要：以Ｅｘｏｔｅｃｈ１００ＢＸ光谱辐射计对不同类型水稻材料无肥处理本田期的监测结果表明，晚熟类型材料武育粳２号，冠层叶色显示出“三黑三黄”的变化节奏。“三黑”出现的时间是：移栽至分蘖末期，枝梗分化期至颖花分化期，花粉母细胞形成及减数分裂期至始穗期；“三黄”出现的时间是：分蘖末期至枝梗分化期，颖花分化期至花粉母细胞形成及减数分裂期，始穗至灌浆期。中熟类型材料汕优６３，冠层叶色显示出“二黑二黄”的变化节奏。“二黑”出现的时间是：移栽至颖花分化期，花粉母细胞形成及减数分裂期至始穗期：“二黄”出现的时间是：颖花分化期至花粉母细胞形成及减数分裂期，始穗至灌浆期。早熟类型材料亚优２号，冠层叶色显示出“一黑一黄”的变化节奏。“一黑”出现的时间是：移栽至颖花分化期；“一黄”出现的时间是：颖花分化期至灌浆期。Monitoring with EXotech 100BX radiometer, the canopy leaf colors of different kinds of rice materials without mp fertilizer applications during their growing periods appear the variation rules of 'blacks and yellows'.'For late maturity rice material Wu Yu Jing No.2, its canopy leaf colors appearthe variation rules of 'three blacks and three yellows'. The processes for 'threeblacks' are those from transplantation to the end of tillering stage, from cladophoredifferentiation stage to spikelet differentiation stage, and from pollen mother cell formation and meiosis stage to initial heading stage. The processes for three 'yellows'are oboes from the end of tillering stage to cladophore differentiation stage, fromspikelet differentiation stage to pollen mother cell formation and meiosis stage, andfrom initial heading stage to grain filling stage.For intermediate maturity rice material Shan You 63, its canopy leaf colors appear the veriation rules of 'two blacks and two yellows'' The processes for 'twoblacks' are those from transplantation to spikelet differentiation stage, and from pollen mother cell formation and meiosis stage to initial heading stage. The processes for'two yellows' are those from spikelet differentiation stage to pollen mother cell formation and meiosis stage, and from initial heading stage to grain filling stage.For early maturity rice material Ya You No.2, its canopy leaf colors appear theveriation rules of 'one black and one yellow'. The process for 'one black' is fromtransplantation to spikelet differentiation stage and the process for 'one yellow' isfrom spikelet differentiation stage to grain filling stage.
