摘　　要：以ROC22为材料,设5个不同的土壤水分处理,观察土壤水分对冬植甘蔗萌芽出苗的影响。结果表明,冬植甘蔗种茎在土壤相对含水量50%～70%范围内萌芽出苗最好;土壤相对含水量在20%以下,冬植甘蔗难以萌芽;土壤相对含水量在95%以上,土壤通气不良,容易引起烂种、烂芽,萌芽率低。Five different treatments were set up,and germination of winter planting sugarcane（ROC22）was observed at different soil moisture.The winter planting sugarcane had the best germination and emergence when the relative soil moisture was 50%[KG-3]-70%.When the soil moisture was below 20%,it was hard for winter planting sugarcane to sprout.When the soil moisture was above 95%,poor soil aeration easily leads to rotten buds and low germination rate.
