摘　　要：根据黑龙江省甜菜纸筒育苗主产区的生产和管理特点,对原“中甜一号甜菜纸筒育苗苗床专用肥”进行了较为系统的配方改进试验。经对甜菜苗床期生长势、根系长、叶柄长、叶片宽、叶片/叶柄的比值等主要性状指标的调查及移栽到田间后对甜菜块根产质量的效应研究表明:在应用原“中甜一号甜菜纸筒育苗苗床专用肥”的基础上,于子叶期喷施“甜菜壮苗剂”有利于培育壮苗;通过对原“中甜一号甜菜纸筒育苗苗床专用肥”进行适当的配方调整,可达到与喷施“甜菜壮苗剂”同样的壮苗效果。According to the characteristics of sugarbeet paper -pot cultivation in the main growing region of Heilongjiang province,we conducted an improvable trial on the original Zhongtian-1special fertilizer for sugarbeet paper-pot cultivation.The investigation which was carried out at seedling stage,leave juvenile stage and harvest stage in growing potential,tap root length,blade width,petiole length,blade /petiole ratio,root yield,sugar content and sugar yield showed that:1)Under the base of Zhongtian-1special fertilizer for sugarbeet paper-pot,sprayed Zhuangmiaoji(agent of sturdy seedling)could indeed control the excessive growth;2)Adjusting the ingredients properly,Zhongtian-1special fertilizer for sugarbeet paper-pot cultivation not only had the same effects as the treatment of Zhuangmiaoji,but also could save at least30Yun/ha.
