摘　　要：2006～2007年以红小豆TH37为材料，采用裂区设计，研究了播种期和钾肥施用量对红小豆产量及籽粒色泽的影响，以确定适宜播种期和钾肥施用量。结果表明：红小豆TH37的适宜播种期为6月25日．钾肥施用量为氯化钾150kg／hm^2。播种期对红小豆产量的影响达到极显著水平，钾肥的作用不显著，二者之间的交互作用也不明显，但钾肥有利于改善红小豆的色泽，在一定范围内，红小豆的亮度值、红度值和黄度值随着钾肥施用量的增加而增加，但过量施用钾肥反而对小豆的色泽起负作用。Based on the method of split-spot design and the material of TH37, the experiment has been carried out in Tangshan in 2006 and 2007. The result showed that the best sowing date was on the 25th of June and the most suitable potassium fertilizer was KC1 150 kg/hm2. It was also discovered that the effect of different sowing dates on yield was significant, but that of potassium fertilizer was not significant. The potassium fertilizer did not significantly interact with sowing date. However, it was helpful in improving the color of A. bean. Therefore, the brightness value, red value and yellow value of A. bean could raise significantly with the increase of potassium fertilizer. On the contrary, those indicators brought down significantly once potassium fertilizer was applicatied over.
