Content and Distribution Characteristics of Main Nutrients in Each Organ of Paris polyphylla Smith var.chinensis Under-forest of Cunninghamia lanceolata
[Objective]To understand the main nutrients content and distribution characteristics in each organ of Paris polyphylla Smith var.chinensis during flowering period in order to provide scientific basis for understory cultivation and nutrient management.[Method]With Paris polyphylla Smith var.chinensis of under-forest the Cunninghamia lanceolata as the research object,samples were collected at flowering stage,and the content and distribution characteristics and their correlation of main nutrients in each organ were analyzed.[Result]N content in each organ was ranked from high to low as leaf,flower,fibrous root,tuber,stem from high to low,and the highest N content in leaf was 29.61 g/kg.P content was ranked from high to low as flower,leaf,fibrous root,tuber,stem,and the highest P content in flower was 4.75 g/kg.K content was ranked from high to low as leaf,flower,stem,fibrous root,tuber,and the highest K content in leaf was 25.23 g/kg.Ca content was ranked from high to low as tuber,fibrous root,stem,leaf,flower and the highest Ca content in tuber was 4.75 g/kg.Mg content was ranked from high to low as leaf,flower,fibrous root,tuber,stem and the highest Mg content in leaf was 3.11 g/kg.The average nutrient content of each organ of Paris polyphylla Smith var.chinensis was ranked from high to low as N,K,Ca,Mg,P.Except N and Mg contents in tuber showed significant negative correlation(P<0.05),the rest of the correlation was not significant.[Conclusion]The nutrients in each organ of Paris polyphylla Smith var.chinensis during flowering period were mainly concentrated in the leaves and flowers.N and P may be the main nutrient elements limiting the growth of Paris polyphylla Smith var.chinensis.
