Relationship between Nutrient Contents in Different Organs of Jasmine at Different Yield Grades
[Objective]The aim was to study the relationship of nutrient content in different organs under different yield grades of jasmine,and provide scientific basis for improving the yield of jasmine.[Method]Through investigation,sampling,testing and statistical analysis,the relationship between nutrient contents in different organs at different yield grades of Jasmine in Hengzhou was systematically studied.[Result]The lower limit of the contents of nitrogen,phosphorus,potassium,iron,manganese,copper,zinc,boron,molybdenum and selenium in different organs at high and slight high yield grades was 1.05-3.00 times of the average contents of middle,low and slight low yield grades.The absorption of zinc,copper and selenium was synchronous in high and slight high yield grades.In the middle,low and slight low yield grades,most of the nutrient contents showed significant and extremely significant positive correlation in the four organs.[Conclusion]The high nutrient content in organs of Jasmine is the basis of high yield.Most of the nutrient contents in the four organs showed significant and extremely significant positive correlation,indicating the importance of fertilization.Under the existing soil conditions,there is no lack of boron and selenium in Hengzhou jasmine field.
