| 摘 要： | 目的]探讨垫江牡丹不同生长期营养特性。方法]采用大田调查和室内化学分析方法研究了垫江牡丹不同生长期植株产量、养分含量、吸收量和土壤有效养分的状况。结果]1~4年生牡丹生物量、叶片重、嫩茎重和丹皮重(产量)与生长年份呈极好的二次回归关系,叶片12种营养元素平均含量和吸收量均以CaNKMgSPFeMnZnCu,这与嫩茎养分平均含量和吸收量的大小序列一致。而丹皮的平均营养元素含量和吸收量为NCaKMgPSFeZnCuMn,与叶片和嫩茎有所不同,同时又不同于叶柄的序列CaKNMgSPFeMnZnCu。牡丹不同生长年份的土壤有机质含量差异较大,其中N、S、Mn、Zn含量丰富。结论]为牡丹高产优质生产提供理论依据。

| Abstract: | Objective] This study aimed to investigate the nutritional characteristics of Dianjiang peony at different growth stages.Method] The yield,nutrient content and nutrient uptake of Dianjiang peony at different growth stages and available nutrient content in soil were investigated by field survey and indoor chemical analysis.Resuit] The results showed that biomass,leaf weight,tender stem weight and cortex moutan weight （yield） of 1-4 years old peony exhibited a significant quadratic regression relationship with the cultivation duration.The average content and uptake of 12 nutrients in leaves exhibited an overall order of Ca＞N＞K＞Mg＞S＞P＞Fe＞Mn＞ Zn＞Cu,which was consistent to that in tender stems.However,the average content and uptake of various nutrient elements in cortex moutan exhibited an overall order of N＞Ca＞K＞Mg＞P＞S＞Fe＞Zn＞Cu＞Mn,which was different from that in leaves and tender stems.In addition,the average content and uptake of various nutrient elements in petioles exhibited an overall order of Ca＞K＞N＞Mg＞S＞P＞Fe＞Mn＞Zn＞Cu.The content of organic matter in soil of Dianjiang peony at different growth stages varied greatly; to be specific,contents of N,S,Mn and Zn were higher.Conclusion] This study provided theoretical basis for the production of high-quality and high-yield peony. |
