摘要
研究了壮苗剂对甜菜纸筒苗生长势、移栽后恢复生长状况等的影响,明确了壮苗剂具有抑制甜菜幼苗伸长生长、培育壮苗等效果。比对照(未喷洒壮苗剂)降低立枯病的罹病率5%～10%,增加根产2.2%～8.3%,提高含糖率0.4～0.63度,增加产糖量5.1%～11.9%,投入产出比达到1∶22。探讨了壮苗剂的喷洒量、喷洒时期等应用技术问题。
Effect of strong-seedling agent on growth vigor and normal growth state of sugar beet with paper pot after trans-planted was studed.The results showed that the strong-seedling agent had the effect on depressing the seedling growing at height and making the seedling strong,the damping-off rate decreased by5%～10%,the root yield increased by2.2%～8.3%,the sugar content increased by0.4～0.63 0 S,the sugar yield increased by5.1%～11.9%,the input-output ratio reached1∶22.Some practical techniques such as applied dosage and suitable period of strong-seedling agent sprayed in sugar beet with paper pot was also explored.
