Study on the Relationship Between Yield and Micronutrient of Jasmine
[Objective]Based on the investigation,sampling,testing and statistical analysis,the relationship between the yield grades of Jasmine and soil micronutrient was studied in Hengzhou,providing a basis for micronutrient fertilization to improve the yield of Jasmine.[Method]The 101 plots were divided into three yield grades:Low yield,middle yield and high yield Soil tests included pH,organic matter,total nitrogen,total phosphorus,total potassium,hydrolyzed nitrogen,available phosphorus,available potassium,and available iron,available manganese,available copper,available zinc,available boron,available molybdenum,and total selenium,plant test items included nitrogen,phosphorus,potassium,iron,manganese,copper,zinc,boron,molybdenum and selenium in roots,branches,leaves and flowers.[Result](1)Each soil micronutrient had a reasonable range,which was the necessary and insufficient condition for high yield micronutrient;(2)There was no deficiency of Fe,Mn,Mo and Se,but a deficiency of Cu and Zn in the soil of Jasmine in Hengzhou.Boron may be at a critical level and soil available manganese may be slightly higher.[Conclusion]The soil of Jasmine in Hengzhou is short of copper and zinc,so it can be micronutrient with copper and zinc fertilizers.
