摘要
[目的]为提高茉莉花产量提供钾营养管理科学依据。[方法]通过调查、采样、测试和统计分析,对横州茉莉花产量与钾营养关系进行系统研究。[结果]①高产地块土壤全钾含量和速效钾含量范围分别为4.5~12.5 g/kg和20~280 mg/kg,为2个必要不充分条件;②土壤全钾含量和土壤速效钾含量与其他土壤养分含量均呈极显著和显著正相关,说明在茉莉花土壤肥力中的养分含量具有一致性趋势;③土壤速效钾含量与茉莉花根K、花K、根Fe、根B、枝Mn含量均呈显著正相关,说明土壤速效钾是关键的肥力指标之一;④土壤全钾含量与茉莉花根、枝、叶、花的其他养分含量呈显著或极显著负相关,说明全钾含量高时影响其他元素的吸收。[结论]土壤速效钾含量和全钾含量是茉莉花关键的肥力指标。
[Objective]To provide scientific basis for potassium nutrition management.[Method]Through investigation,sampling,testing and statistical analysis,the relationship between the yield and potassium nutrition of Jasmine in Hengzhou was studied.[Result]①The range of total potassium content and available potassium content in high yield plots were 4.5-12.5 g/kg and 20-280 mg/kg,respectively,which were two necessary and insufficient conditions.②The contents of total potassium and available potassium in soil were significantly and positively correlated with the contents of other soil nutrients,indicating that the nutrient contents in the soil fertility of Jasmine had a consistent trend.③The content of soil available potassium was positively correlated with the content of root potassium,flower potassium,root iron,root boron and branch manganese,indicating that soil available potassium was one of the key fertility indexes.④The content of total potassium in soil was negatively correlated with the content of other nutrients in root,branch,leaf and flower of Jasmine,indicating that the high content of total potassium hinders the absorption of other elements.[Conclusion]The content of available potassium and the content of total potassium were the key fertility indexes of Jasmine flower.
