在中国农科院陵县试验区选择了5种不同农牧结合类型、24个农户进行试验和调查。研究表明:农牧结合能节省化肥投资,使作物高产稳产。随着农户饲养畜禽数量和亩均占有标准畜的增加,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/养牛较好,种植/养羊、种植/养猪居中,单一种植较差。表明农牧结合是培肥地力,促使作物高产稳产低成本的有效途径。
Five different types of combination of agriculture and animal husbandry were selected in Lingxian pilot area of Chinese Academy of Agricultural Sciences and 24 farmers were tested and investigated. The research shows that the combination of agriculture and animal husbandry can save fertilizer investment and make the crop stable and high yield. With the increase of the number of livestock and poultry farmers and the standard stock of livestock, the content of soil organic matter, total nitrogen and alkali-hydrolyzed nitrogen can be significantly increased. With the increase of input of organic and inorganic phosphorus in farmer households, the content of total phosphorus and available phosphorus in soil had a significant impact. Among the 14 indicators of comprehensive benefits, planting / raising of chicken, planting / raising of cattle is good, planting / raising sheep, planting / raising of pigs are centralized, and single planting is poor. It shows that the combination of agriculture and animal husbandry is an effective way to cultivate fertility and promote high and stable low-cost crops.
