摘要
[目的]为茉莉花养分管理提供科学依据.[方法]采集横州市 38 个茉莉花地块的根、枝、叶、花样本,测定氮、磷、钾、铁、锰、铜、锌、硼、钼、硒含量,并对不同器官养分含量及其关系进行分析.[结果]①养分含量多的器官为花和叶,是叶面施肥的依据;②多数养分之间呈显著和极显著正相关,说明平衡施肥的重要性;③锌和铜的吸收具有高度一致性,磷和钾、铁和磷吸收具有互促性.[结论]结果为茉莉花产量和品质的提高提供了科学依据.
Abstract
[Objective]In order to provide scientific basis for nutrient management of jasmine.[Method]Samples of root,branch,leaf and flower were collected from 38 jasmine plots in Hengzhou.The contents of nitrogen,phosphorus,potassium,iron,manganese,copper,zinc,boron,molybdenum and selenium in different organs were measured.[Result]①The organs with high nutrient content were flower and leaf,which were the basis of foliar fertilization.②Most nutrients showed significant and extremely significant positive correlation,which indicated the importance of balanced fertilization.③The absorption of zinc and copper was highly consistent;phosphorus and potassium,iron and phosphorus absorption have mutual promotion.[Conclusion]The results provide a scientific basis for improving the yield and quality of jasmine flower.
