Abstract

Based upon the plant nutrient conservation strategy ecogical similarity of ex-situ conservation , the nutrient status and the soil condition of 21 kinds of ex-situ conservation rare plants of Magnoliaceae and Lauraceae in Wuhan Botanical Garden were studied .The results showed that the sequence of average content of macronutrients in the soil was Ca Mg N K S P .The sequence and the average content of macronutrients indicated that the contents of available nitrogen , phosphor and potassium were low in the soil .And through the analysis of the average contents , background content and the ratio of N P , it was found that the contents of phosphorus , sulphur and nitrogen were low in the plant leaves too .The bioavailability sequence of the 6 elements was N PK S Ca Mg , which could reflect the damand sequence of plant in some way .Based upon the analysis of the nutrient status of plant leaves and soil , it was suggested that more N , P and K should be added inthe soil to assure the success growth of rare plant from seed to seed .[ Ch , 1 fig .6 tab .17 ref .]
