%X The results from field experiments,animal feeding experiments and comprehensive agro-husbandary entities showed that the untrient recovery rate for the whole agro-husbandary ecosystem reached 49.9% for N and 37.6% for P,in farmland subecosystem nutrient use effeciency was 56.9% for N and 36.3% for P,which were 10-20% higher than in single cropping system.It was suggested that this agro-husbandary ecoagricultural model be appropriate for development of resource-saving eco-agriculture in the plain located in front of Mountain Taihang.
