国际干旱地区农业研究中心(ICARDA)研究人员成功地创立了牧草和畜牧管理系统。该系统能改良那些不适于耕作或退化甚至沙化的土壤,提高畜牧业生产。方法是施加适量磷肥以刺激牧场豆科植物生长。磷能刺激豆科植物吸收大气中的氮,同时也促进了牧草生长,给畜牧业捉供了大量牧草 Researchers at ICARDA have successfully created forages and livestock management systems. The system can improve the soil that is not suitable for tillage or degradation or desertification and improve the livestock husbandry production. The method is to apply a suitable amount of phosphate fertilizer to stimulate the growth of pasture legumes. Phosphorus can stimulate legumes to absorb nitrogen in the atmosphere, but also to promote the growth of forage grass, livestock husbandry to provide a large number of forage
