【摘要】 分析了我国有机肥的现状与发展前景。我国有机肥的资源丰富,数量持续增长,质量却有所降低,利用率也在下降。有机肥利用技术不适应当前农村的新需求,以及有机肥管理工作不到位,是我国有机肥利用率下降的主要原因。今后应以秸秆与畜禽粪便的简便处理、直接利用为主要发展方向,争取逐步达到5000万t养分的年施用量,与化肥形成1∶1的施用比例,实现合理的施肥策略。更多还原

【Abstract】 This paper analyzed the status of organic fertilizer and its future perspective in China.Although the resources of organic fertilizer are abundance and still increase,the quality and utilization rate of organic resources decreased.The main reasons for the decrease rate of utilization are that the techniques of organic fertilizer use have not adapted to the new demand in rural area,and management of organic fertilizers is absent.The development orientation in utilization of organic resources is simple treatment and direct use of crop residues and animal manure. The objective is to use 50 million tones of nutrients annually derived from organic materials,and the ratio of nutrient from organic and inorganic fertilizer is equivalent in order to realize rational fertilizer application strategies.更多还原
