摘　　要：该研究于１９８９～１９９２年在广西甘蔗研究所盆栽试验场进行。在广西的红壤土、气候、主栽品种、施肥水平的条件下，研究了甘蔗的养分吸收参数和吸收规律。吨原料蔗吸收钾素量在２．０６１±１．３９６（２Ｓ）ｋｇ范围内变化。吨原料蔗吸收钾素量在品种间相差不大，而在不同施肥水平、土壤肥力及栽培制度条件下有一定的差异。The study of sugarcane potted was carried out in the Guangxi Sugarcane Research Institute during 1989-1992 The parameter of nutrients absorbed by sugarcane from soil and the absorbed law were studied under representative conditions in Guangxi,including red earth,main cultivars,fertilizing level and climatic conditions Results shown that the potassium(K 2O)was absorbed from soil at a range of 2 061±1 396(2s)kg per tonne of milling cane The rate of the potassium abserbed is few different among the varieties,but there are certain different rates under different fertilizing level,fertility of soils and planting regulation
