Application of chemical fertilizer combined with reasonable organic manure was the available approach in developing sustainable agriculture by keeping the balance of microelement and decreasing the risk of heavy metal pollution
(Kong and Ni 2006). Organic manure returning to the soil was necessary for resolving the negative environment effect by excessive application of organic manure and the atmosphere pollution by straw setting on fire. The study on method of organic material returning to soil is needed. That includes the straw decomposing fleetly, the excrement of human and livestock fermenting, the waste selecting and disinfecting. The industrialization and commercialization of organic manure
would be the developing direction with the intensive agriculture and the denseness of labor force.
