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 production and management of the main producing areas of beet paper tube seedlings in Heilongjiang Province, a more systematic improvement experiment was conducted on the original “Zhongtian-1 beet paper tube seedling seedbed special fertilizer”. The investigation of the main traits such as growth potential, root length, petiole length, leaf width and leaf / petiole ratio of sugar beet seedling and the effect on root quality of sugar beet after transplanting to the field showed that: Beet paper tube seedling seedling bed special fertilizer “based on the cotyledon spraying” sugar beet seedling agent “is conducive to nurturing strong seedlings; by the original” in sweet beet paper tube seedling seedling bed “for the appropriate formula Adjustment, can be achieved with the spray ”beet seedling agent" the same strong seedling effect.
