摘要
为明确早收栽培情况下,心香甘薯延后收获的薯块膨大增重动态,开展了早收栽培下,心香甘薯延后收获的分期掘薯观察试验。研究结果表明,心香甘薯不但结薯早、前期薯块膨大快,而且后期薯块膨大增重比例也相当高,心香在早收栽培下延后收获,也能取得较高的产量。
To understand the expanding and weight-increasing dynamic of root tubers of sweet potato cultivar Xinxiangunder early harvest cultivation with delayed harvest,the observation experiment of the potato digging at different growth stages was carried out.The results showed that the cultivar Xinxiang were with characteristics of early root tuber setting,quickly expanding at early stage,and high ratio of tuber expanding and weight-increasing at later stage.Therefore Xinxiang could be harvested at a higher yield under early harvest cultivation with delayed harvest.
