Abstract

Abstract: Using in the soil with different gravel content to simulate the soil conditions with different rock desertification degrees, the distribution law of mineral elements in Dalbergia odorifera was studied by pot culture. The results showed that the contents of N, K, Ca and Mg in Dalbergia odorifera leaves were generally higher than those in stems and roots. Different gravel content had an impact on the distribution of mineral elements in Dalbergia odorifera. With the increase of gravel content, the content of Ca and Mg in Dalbergia odorifera had an overall upward trend; under different gravel content conditions, the content of N elements in Dalbergia odorifera did not change significantly, but the content of P and K elements changed significantly. Revealing the distribution law of mineral elements in Dalbergia odorifera under the rocky desertification environment could provide reference for the scientific management of rocky desertification.

Key words: Dalbergia odorifera, soil gravel content, element content, element allocation
