通过５年有机质分解、积累与平衡定位试验和有机物料腐殖化速率测定，及９年Ｎ、Ｐ平衡定位试验的结果表明，实行秸秆还田有明显的培肥和增产效果。Ｎ、Ｐ平衡施用，配合秸秆还田的土壤有机质９年增加０．２２％，有机肥试验的秸秆还田处理较对照增产７．３％～１１．１％；栾城县推广桔秆机械粉碎还田，实行有机无机结合施肥制度，１１年土壤有机质提高０．２７％，全Ｎ增加０．０１％。为华北山前平原高产区农业持续发展提供了土壤培肥技术和途径。
Through 5 years of organic matter decomposition, accumulation and equilibrium localization test and organic material humification rate determination, and 9 years of N, P equilibrium positioning test results show that the implementation of straw returning to the field have obvious fertilizer and increase yield. N, P balanced application, combined with straw returning soil organic matter increased by 0.22% 9 years, organic fertilizer experiment straw returning treatment yield 7.3% ~ 11.1% compared with the control; Luancheng promote orange stalk mechanical crushing Back to field, the implementation of organic and inorganic fertilization system, soil organic matter increased by 0.27% in 11 years, all N increased by 0.01%. Which provided soil fertility-improving techniques and ways for the sustainable development of agriculture in the high-yielding areas in the piedmont of North China.
