摘　　要：为了探讨早收栽培甘薯(Ipomoea batatas L.)品种浙薯132延后收获的薯块膨大增重动态,开展了浙薯132延后收获的分期掘薯观察试验。结果表明,浙薯132不但结薯较早,前期薯块膨大快,而且后期薯块膨大增重比例也较高,其延后收获也能取得较高的产量。To understand the expanding and weighting dynamic of root tuber of sweet potato（Ipomoea batatas L.） variety Zheshu 132 under early harvest cultivation with delayed harvest,delaying harvested potato was dug at different growth stages and observed.The results showed that except for early setting and quickly expanding of root tuber at early stages,the root tuber of Zheshu 132 also had high expanding and weighting rate at later stages,indicating that high yield of Zheshu 132 could be obtained with delayed harvest under early harvest cultivation.
