以Exotech 100BX光谱辐射计监测结果表明,中籼稻杂交组合汕优63本田期冠层叶色显示出“二黑二黄”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。这种变化受水稻自身内在节奏的制约,“黑黄”程度依肥水管理措施为转移。
The monitoring results of Exotech 100BX spectroradiometer showed that the leaf color of mid-indica hybrid rice combination Shanyou 63 in Honda period showed rhythm of “two blacks and two yellows”. “Two black” appeared time: transplanting to spike flower differentiation; pollen mother cell formation and meiosis to the beginning of the ear. “Two yellow” appear time is: spikelet differentiation to pollen mother cell formation and meiosis; start ear to filling stage. This change is governed by the inner rhythm of rice itself, and the degree of “black and yellow” is transferred according to the fertilizer management measures.
