不同施肥模式下甘蔗产量糖分与叶片氮磷钾关系研究

Study on the Relationship Between Yield, Sugar Content and N, P, K Content in leaf Under Different Fertilization Models in Sugarcane

采用三种施肥模式，研究了甘蔗产量、糖分与叶片氮、磷、钾含量及元素比值的关系。结果表明，不同施肥模式下和不同生长期的叶片氮、磷、钾含量以及氮／磷、氮／钾和磷／钾比值都有差异，而这些差异明显地影响甘蔗产量、糖分的形成和积累。

An experiment was conducted on. the relationship between yield, sugar content. and nitrogen (N), phosphorus (P), potassium (K) in leaf under different fertilization models in sugarcane. The result showed that under different models and during different growth stages, there were differences in the N, P. K, as well as N/P, N/K, P/K ratio, which affected the formation and accumulation of cane--yield and sugar-content in sugarcane.
