摘要
为明确早收栽培情况下,浙紫薯3号紫甘薯收获推迟后的薯块膨大动态,开展了浙紫薯3号紫甘薯在早收栽培下推迟收获的分期挖薯观察试验。试验结果表明,浙紫薯3号不仅具有结薯早,前期薯块膨大快的特点,而且后期薯块膨大增质量比例也相当高,浙紫薯3号在早收栽培下,若延后收获,也能取得较高的产量和效益。
In order to clarify the swelling trend of Zhejiang purple potato No.3 after postponement of harvest under early harvest cultivation,the observation experiment of delayed harvest of Zhejiang purple potato No.3 under early harvest cultivation was carried out.The results showed that Zhejiang purple potato No.3 not only had the characteristics of early tuber setting and rapid tuber swelling in the early stage,but also had a high proportion of tuber swelling and weight gain in the late stage.Under early harvest cultivation,Zhejiang purple potato No.3 could also obtain higher yield and benefit if harvested later.
