Study on the Relationship Between Yield and Phosphorus Nutrition of Jasmine
[Objective]The aim was to study the relationship between jasmine yield and soil phosphorus content,plant phosphorus content,and provide scientific basis for phosphorus nutrition management to improve jasmine yield.[Method]Through investigation,sampling,testing and statistical analysis,the relationship between phosphorus nutrition and Jasmine yield in Hengzhou was systematically studied.[Result]Soil total phosphorus content of 0.062-0.149 g/kg and available phosphorus content of 4.8-90.0 mg/kg were necessary and insufficient conditions for high-yield plots.Soil total phosphorus content was positively correlated with soil total nitrogen content,soil total potassium content,soil available phosphorus content,soil available potassium content and available iron,manganese,copper,zinc,boron and molybdenum content.The reason is that the soil with high soil total phosphorus content also has high soil organic matter content.In this case,the content of various nutrients is also high.There was a significant and extremely significant positive correlation between soil available phosphorus content and branch and leaf phosphorus content,indicating that the higher the soil available phosphorus content,the higher the branch and leaf phosphorus content,which was conducive to flowering.The content of soil available phosphorus was significantly or extremely significantly positively correlated with the content of many nutrients in the four organs of jasmine,indicating that high soil available phosphorus promoted the absorption of other nutrients.[Conclusion]The range of soil total phosphorus content and available phosphorus content were 0.062-0.149 g/kg and 4.8-90.0 mg/kg,respectively.Soil available phosphorus is one of the key fertility indexes of jasmine.
