摘要： Banana trees and poultry dung were used as the main source of compost. The experiment method was orthogonal experiment design (three factors, three levels). The C/N (Organic carbon/Nitrogen) ratio in the compost, the pile-turning interval and the initial moisture were influencing factors on the nitrogen variation during the compost process It is seen that the C/N ratio effectively influences the nitrogen variation; the initial moisture and the pile-turning interval do not have evident effect on the nitrogen variation. The study found that the C/N ratio is the key condition of affecting the nitrogen variation among the basic condition of the banana trees and the poultry dung compost progress. The gradient experiment shown that when the C/N ratio is 25/1, the initial moisture is 65% and the pile-turning interval is 48 hours, the compost progress has the least nitrogen loss.
