摘　　要：以木薯品种GR4种茎为材料,分别采用清水和1.5%石灰水浸泡木薯种茎,研究不同浸泡时间对木薯农艺性状及产量性状的影响。结果表明:室外贮藏30 d后,短时间清水处理对木薯的茎径、株高、单株结薯数具有显著促进作用;石灰水处理后,薯干率、鲜薯淀粉产量得到极显著提高,鲜茎叶产量、鲜薯产量、薯干产量、淀粉产量得到显著提高;2种浸种液均以浸泡3 h最为适宜,且石灰水浸种的效果优于清水浸种。The effects of different soaking time of lime water on agronomic characters and yield characters of cassava were studied, with cassava varieties GR4 stem varieties as material, with water and 1.5% limewater soaking seed-stem of cassava, respectively. The results showed that the outdoor storage after 30 d, the water soaking can improve plant height and diameter of cassava, the limewater soaking can improve the increase in survival rate, fresh tuber weight per plant, starch yield of cassava and dry tuber yield of cassava, the soaking treatment time is better to 3 h. The effect of lime water immersion was better than that of water immersion.
