我国是一个人口大国、农业大国,也是一个肥料生产和消费大国。肥料对农业生产的发展,特别是在增加粮食产量方面起到了重要作用。我国用占世界7%的耕地,养活了占世界22%的人口。我国引进化肥已有五十多年历史,由于受传统施肥观念的影响,在农业生产中因长期大量施用常规化肥,出现了施用后释放快、与作物吸收不同步,导致其大量养分损失,造成土壤、水资源以及大气的污染,降低了农产品品质、导致作物的病虫害加剧等问题。科学研究表明,如何能提高肥料利用率及减少化肥对环境的污染,提高农产品品质以及降低农业生产成本,解决目前常规化肥溶解过快与作物生长需肥规律的协调统一,使农业生产走可持续发展之路,已成为世界肥料界研究的热点和难点。由国家磷复肥研究中心许秀成教授经过十几年的精心研究与探索,终于研究开发出了一种国家专利产品———“离不了”牌缓释·控释包膜复合肥,在济南乐喜施肥料有限公司投入批量生产。“离不了”牌缓释·控释包膜复合肥施用后能明显延长肥期,并可延迟作物对其营养成分吸收利用,大大地提高了肥料的利用率。该肥充分利用了材料的热物理性质,通过温度的变化使肥料与作物之间达到了协调统一,从而降低了过多养分对环境的污染,彻底解决了肥料释放速率与作物生长季节养分需求的矛?
Our country is a big country with a large population and a big agricultural power. It is also a large producer and consumer of fertilizers. Fertilizers have played an important role in the development of agricultural production, especially in increasing food production. With 7% of the world’s arable land, our country feeds about 22% of the world’s population. Since the introduction of fertilizer in China for more than 50 years, due to the influence of traditional fertilization concepts, due to long-term large-scale application of conventional fertilizers in agriculture, there has been a rapid release after application and an unsynchronized absorption with crops, resulting in a large amount of nutrient loss, resulting in Soil, water resources and atmospheric pollution, reducing the quality of agricultural products, leading to crop pests and diseases and other issues. Scientific research shows that how to improve the utilization of fertilizers and reduce the pollution of chemical fertilizers to the environment, improve the quality of agricultural products and reduce the cost of agricultural production, to solve the current common fertilizer dissolved overly fast and crop growth and fertilizer need to harmonize the law of sustainable agricultural production to go The development of the road, has become the world fertilizer industry research hot and difficult. By the National Research Center of phosphate compound fertilizer Xiu-Cheng Xu after ten years of careful research and exploration, and finally developed a research and development of a national patent product - “can not leave” controlled release coated capsule compound fertilizer, Jinan Le hi Fertilizer Co., Ltd. put into mass production. “Inseparable” brand slow-release coated controlled-release coated compound fertilizer can significantly extend the fattening period, and delay the absorption of nutrients on their crops, greatly improving the utilization of fertilizer. The fertilizer takes full advantage of the thermophysical properties of the material, through the temperature changes so that fertilizer and crop reached a coordinated between, thus reducing the excessive nutrient pollution to the environment, completely solve the fertilizer release rate and crop growth season nutrient requirements spear?
