摘要: 应用32P示踪研究了不同 磷水平番 红花植株中磷的动态变化.结果表明：不同磷水平的番红花植株吸收磷的总量与相应所施磷 量基本上呈倍数关系，低于Hangland营养液磷水平处理的植株处于磷饥饿状态；地上部磷含 量与地下部磷含量的比值也随磷水平的降低而下降；随磷水平的下降，植株地上、地下部干 质量降低，单株生物量减少，最终影响番红花新球茎的生长的品质.Abstract: Using 32P tracer technology,this paper st u dies the dynamic variation of phosphorus in different phosphorus levels of Ccr ocus sativus L. Plants.The results show as the following. (1) The total amounts of phosphorus in different phosphorus levels plants and it s corresponding supplying amounts of phosphorus show the double relationship. Th e plants under the treamont of 1 P are in the state of phosphorus insufficiency; (2) With the reducement of phosphorus levels, the radio between phosphorus of un der ground and surface decrease; (3) Under the condition of low phosphorus, the dry wight of surface and under gr ound plants decrease,and the growth of single plant biomass slows down, which af fects the growth and quality of new coms of Crocus sativus L. As a result.
