广西旱地甘蔗养分吸收参数研究——第2报甘蔗磷素养分吸收参数

Studies on the Nutrients Parameter of Sugarcane in Guangxi Drought Land ⅡPhosphorus Parameter

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、主栽品种、气候、施肥水平条件下，研究了甘蔗养分的吸收参数和吸收规律。吨原料蔗吸收磷素（Ｐ２Ｏ５）量在０．７６４±０．６００（２Ｓ）Ｋｇ范围内变化。吨原料蔗吸收磷素量与品种，施肥水平、土壤肥力及栽培制度均有一定的关系。

The study of potted sugarcane was carried out in Guangxi Sugarcane Research Institute during 1989-1992 The nutrients parameter 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 phosphorus (P2O5) was absorbed from soil at a range of 0746±0600(2s) kg per tonne milling cane The rate of phosphorus absorbed relates with varieties, fertilizing level, fertility of soils and planting regulation
