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 research was carried out in Guangxi Potato Research Institute pot experiment field from 1989 to 1992. The nutrient absorption parameters and absorption laws of sugarcane were studied under the conditions of red soil, climate, main cultivars and fertilization level in Guangxi. The amount of K absorbed by raw material cane changed within the range of 2.061 ± 1.396 (2S) kg. The amount of K absorbed by raw material cane did not differ much among different cultivars, but was different under different fertilization levels, soil fertility and cultivation system.
