摘要

Taking 0-30 cm, 0-40 cm, 0-50 cm, 0-60 cm of dry land Fenlong and 0-40 cm paddy field as samples of soil profile with corresponding original soil as the control group, we measured content of organic matter, quick-acting N, quick-acting P and quick-acting K, effective B, Cu, Zn and Mn. Results indicate that available nutrients in soil after Fenlong were higher than original soil. For dry land, the increase of organic matter, quick-acting N, quick-acting P and quick-acting K is 3.02%-35.16%, 6.80%-39.54%, 2.81%-44.46%, and 7.72%-53.71% respectively. There is also increase in effective content of trace element, B, Cu, Zn and Mn. For paddy field, the increase of organic matter, quick-acting N, P and K is 19.64%, 24.02%, 24.27% and 57.78% respectively. Besides, there is also increase in content of trace element, B, Cu, and Zn. On the basis of analysis, we put forward the new theory of crop cultivation "root" theory.
