摘要
以杂交油菜 黄杂1号"为供试材料,研究钾肥对干物质积累量及其在器官分配的影响.结果表明,施钾可增加其根、茎等营养器官的物质积累并促进干物质由营养器官向籽粒的转移.增施钾肥主要促进分枝尤其是中、下位分枝的生长.在本试验土壤条件下,分期施钾肥对干物质积累的效应优于一次性基施.
Hybrid rape'Huangza 1' was used in this study to investigate the effect of potassium fertilizer on dry matter accumulation and its partition in different organs of rape. Result showed that dry matter accumulated in vegetative organs of rape plant and its transportation to seed could be significantly enhanced by potassium fertilizer. Potassium fertilizer mainly promoted dry matter accumulation of branches, especially those on middle and lower part of rape plant. Compared with single basal application, superior effect of separate application of potassium fertilizer on dry matter accumulation was observed in this study.
