应用 3 5S研究石斛吸收硫素的规律 ,结果表明 :石斛对硫的吸收量随培养时间(1～ 2 5d)增加而增多 ;随培养温度的上升而增多 ;随培养液中氮、磷、钾的减少而减少 ,其减少程度是缺氮大于缺钾、缺钾大于缺磷。石斛吸收硫量是茎大于叶
The application of 35S to study the law of absorption of sulfur by Dendrobium showed that the absorption of sulfur by Dendrobium increased with the increase of culture time (1-25d), increased with the increase of culture temperature, increased with the increase of nitrogen, phosphorus and potassium Reduce the reduction is less than the lack of nitrogen deficiency potassium deficiency, potassium deficiency than phosphorus deficiency. Dendrobium absorption of sulfur is larger than the stems of the stems
