| 摘 要： | 为了进一步挖掘纸筒育苗的增产潜力,根据日本的成功经验,设计了通过不同播种时期以形成不同苗龄移栽试验。结果表明,提早播种,延长育苗期,使苗龄达到35 d～40 d,平均产量达到57.5 t.hm-2～60.7 t.hm-2,比苗龄25 d的对照增产甜菜7.7%～13.9%,块根含糖率提高0.1%～0.4%。其中40 d苗龄增产和增糖幅度最大。正常年份,黑龙江中部甜菜产区,在4月8日之前播种育苗,能够进一步发挥纸筒育苗的增产潜力。图2,表1,参4。

| Abstract: | In order to further improve sugar beet production,based on Japans successful experience,the extension of seedling-raising duration was carried out by different sowing dates.The results showed that early sowing and thus the extension of seedling-raising duration to 35-40 days,could increase sugar content by 0.1-0.4% and yield by 7.7%-13.9% respectively compared to 25 day-seedlings.The average yield is 57.5 t·hm-2-60.7 t·hm-2.40-day seedling has the greatest increase in root yield and sugar content.In a regular year,it is suggested in the central areas of Heilongjiang province,sugar beet sowing before April 8 can better display the potential yield increasing effect for paper pot sugar beet. |
