1991～1993年进行了甜菜纸简育苗移栽密度试验。通过对甜菜单株重、产量、含糖率、叶面积系数、根冠比的调查得出：甜菜纸筒育苗移栽以70cm×25cm的密度为合理的群体结构，表现出丰产、高糖的优势。
From 1991 to 1993, we conducted a simple transplanting density test of beet paper. Through the investigation of sweet plant weight, yield, sugar content, leaf area coefficient and root / shoot ratio, the results showed that the density of 70cm × 25cm transplanting of sugarbeet paper tube was a reasonable population structure and showed high yield and high sugar Advantage.
