摘要
[目的] 研究磷酸二氢钠对盆栽雪菊(Coreopsis tinctoria)生长及产量的影响.[方法]设置 6个不同NaH2PO4处理水平,分别为0、0.1、0.2、0.3、0.4、0.5 g/kg,分析不同施磷条件下雪菊的植株性状、产量.[结果]施用0.3 g/kg NaH2PO4,盆栽雪菊植株生理性状最佳;施用0.5 g/kg NaH2PO4,植株性状最差.施用0.3 g/kg NaH2PO4,7-9月盆栽雪菊总鲜花产量和总干花产量最高.特别9月表现最突出,8月次之,7月最低.[结论]施用磷肥可以显著影响盆栽雪菊的生长和产量,该研究可为盆栽雪菊的磷肥施用提供参考.
Abstract
[Objective]The effects of sodiumed dihydrogen phosphateon growth and yield ofpotted Coreopsis tinctoria were researched.[Method]This experiment set 6 different NaH2PO4 levels,divided into 0,0.1,0.2,0.3,0.4,0.5 g/kg.Plant character and yield of potted Coreopsis tinctoria were studied under different phosphorus levels.[Result]when the amount of NaH2PO4was 0.3 g/kg ,physiological characters of potted Coreopsis tinctoria were the best; when the amount of NaH2PO4was 0.5 g/kg ,physiological characters of potted Coreopsis tinctoria were the worst.Total fresh flower production and total dry flower production were the highest when the amount of NaH2PO4was 0.3 g/kgfrom July to September.Especially in September,theyield was the highest,the next was in August,the yield in Julywas the lowest.[Conclusion]Applying phosphorus can affectgrowth and yield ofpotted Coreopsis tinctoria.The research can provide reference for application of phosphate fertilizer.
