摘要
通过试验和大面积生产示范,明确了覆膜甜菜补栽纸筒苗保全苗的增产效果显著;缺苗率10.9%,补栽全苗,增产25%,产糖量增加18.9%,投入产出比显著,达1∶7.38。
The demonstration test of film-covering sugarbeet field filling the gaps with paper-pot seedlings was conducted. The sugarbeet seedling was filled when missing seedling rate was up to 10.9%, the root yield was increased by 25%,sugar yield increased by 18.9%, the input-output ratio was as 1：7.38.
