The results show that the oils analyzed include biodegraded and normal oils,they are of the same genetic type,their organic parent materials are mixed ones,their higher plants make a great contribution to the oil generation,while bacteria are very important for the higher plants to reconstruct.

The research explored the soil fertility status of paddyfield developed by different parent materials in comparative method,and studied the soil fertility level in universal assessment method(INDEX model).

Rubber seedlings were pot cultured with and without fertilizer on the soils derived from 4 different parent materials to observe their growth.

Effects of different mother material soils on biochemical characteristics of oolong tea;

Authors discussed the main original bodies of gas-oil formation in different stages in China, which enrich main mother material of gas-oil formation named sporopollen element and lignin.

The results shwed: when the mother materials were the same,thecopper adsorption of the soils of three kinds of textures was heavy loam>medium loam> lightloam; when the texture was the same,the adrorption of the soils which developped from differ-ent mother materials was Gneiss soil<Quaterinary Red.
