摘 要:试验结果表明,在同等条件下,由于栽培方式不同,密度不同,块根产量、产糖量差异较大,以纸筒大垄双行为最好,甜菜块根产量、产糖量比对照小垄直播分别提高36.7%、39.8%,每公顷纯增效益1602元。其次是大垄双行覆膜,块根产量、产糖量比对照小垄直播分别提高31.5%、33.1%。The experimental results showed that there was a significant difference between root yield and sugar yield under different planting patterns,the root yield and sugar yield were increased by36.7%and39.8%respectively,and the net profit was increased by1602Yuan per ha for two lines within wide row with paper-pot in comparison with the treat of direct sowing in normal row.Moreover,the root yield and sugar yield for film mulching two lines within wide row were increased by31.5%and33.1%respectively.
