Response of Soil and Plant Nutrients to Planting Years in Precious Ancient Camellia tetracocca Plantations

In order to explore the response of soil nutrient supply capacity and tea plant utilization tea-planting years in precious ancient garden, field investigation indoor analysis methods were employed research content, eco-stoichiometric characteristics correlation between them, with artificially bred Camellia tetracocca at different time periods (5 years, 15 25 40 years). The results showed that: (1) contents organic carbon total nitrogen higher 25- 40-year teas than 5- 15-year teas. pH phosphorus highest tea, available content was lowest tea. (2) nitrogen, potassium shoots trees according following order: new > leaves branches. (3) N: P 4.11–7.55 6.37–11.76, respectively. Available nutrients main factors affecting shoots. conclusion, plants garden significantly under years. growth restricted by supply. absorption 15- 25-year teas, study provides basis for rational development sustainable plants, scientific management gardens.
