摘　　要：经对中国农业科学院陵县试验区选择5种不同类型、24个农户进行试验和调查研究表明,农牧结合能充分利用社会自然资源,具有较高的经济效益,能节省化肥投资,促使粮食作物高产稳产。同时随着农户饲养畜禽数量的增加,能明显提高土壤有机质、全氮、碱解氮含量。随着农户有机无机磷肥料投入量的增加,对土壤全磷、速效磷含量产生明显影响。在综合效益的14个指标中,以种植/养鸡、种植/养牛较高,种植/养羊、种植/养猪居中,单一种植户较差,从而表明农牧结合是农户提高经济效益,增加收入,培肥地力和保持农业持续发展的有效途径。Experiments and investigations to 5 types,total 24 households in Lingxian Experimental Region, CAAS, showed that combining farming with animal-husbandary can fully utilize social natural resources, achieve high economic benefits,reduce fertilizer input and guarantee the high and stable production of agriculture. With the increasing of livestock raised,soil nutrient contents such as organic matter, total N,alkaline N were increased,and soil total P and available P were also improved along with the increasing input of organic and inorganic phosphorus fertilizers. According to a 14 comprehensive benefit index,farming/chicken raising and farming/cattle breeding had the highest benefits,farming/sheep raising and farming/pig raising followed as the next,single farming had the lowest benefits. So combination of farming with animal husbandary can improve economic benefits of households and also can increase soil fertility.
