| 摘 要： | 为明确当前东北甜菜生产上普遍采用的纸筒育苗移栽田肥料的合理使用方法,历经3年,在黑龙江的气候相对湿润的中东部区和相对干燥的西部区,采用田间小区试验,通过设置距离纸筒苗的横向距离和施肥深度2个变因,研究了氮磷钾三元素混合肥料不同施肥位置对纸筒育苗栽培方式下的甜菜产质量影响。结果表明：移栽时不坐水条件下,肥料施用距纸筒的横向距离越近,增产效果越好,深度10、15 cm处理效果相当,两者均比深度5 cm处理显著增产;如移栽时坐水,施肥距纸筒的横向距离选择5 cm,施肥深度10-15 cm对甜菜块根产质量最有利;无论移栽时坐水或不坐水,施肥的横向或纵向位置对甜菜块根含糖影响较小,不同处理之间差异不显著。

| Abstract: | In northeast China, paper pot culture is a popular method in sugar beet production, in order tounderstand the right fertilizing place in this kind of culture, a three years field plot trial was conducted in therelatively wet（central and eastern Heilongjiang） and relatively dry（western Heilongjiang） region. The effects ofNPK compounds placement was studied by a design of 2 variables, i.e. vertical and lateral variable weredesigned as 5, 10, 15 cm and 0, 5, 10 cm respectively. The results showed that when no water at transplanting,for the factor of lateral, the nearer of the distance of fertilizer to the paper pot, the higher of the beet root; for thefactor of vertical, both 10 cm and 15 cm showed a significant higher root yield than 5 cm. When watered attransplanting, the fertilizer placed at the lateral direction of 5 cm and vertical direction of 10-15 cm was themost suitable choice for sugar beet yield and quality. Whether it was watered or not at sugar beet transplanting,the fertilizer placement had little effects on sugar content of sugar beet root. |
