国外化肥生产趋势是朝着高浓、复合、长效化方向发展,目前世界上发达国家的化肥大部分以复肥形态施用.各国生产的复肥品种种类繁多,就其养分形态、含量、比例、添加成分、剂型来看,各有不同.国内过去在复肥品种和施用技术方面曾做了不少工作,但离农业现代化的要求还有很大差距.我国地域辽阔,作物种类繁多,土壤、气候条件差异悬殊,故依靠少数几种复肥品种是远远满足不了农业生产发展的需要.因此,为了因地制宜地发展适合的复肥,并
The trend of fertilizer production in foreign countries is towards high concentration, compound and long-term development. At present, most of the chemical fertilizers in the developed countries of the world are applied in the form of compound fertilizers. There are various types of compound fertilizers in various countries and their nutrient forms, contents, , Add ingredients, dosage forms of view, have different.China in the past in the complex fertilizer varieties and application technology has done a lot of work, but far from the requirements of agricultural modernization there is a big gap between China’s vast territory, a wide range of crops, soil , Different climatic conditions, so relying on a few types of compound fertilizer far can not meet the needs of agricultural production development.Therefore, in order to suit the local development of suitable compound fertilizer, and
