【摘要】 涂层缓释一次肥以其独特的缓释增效功能,成为农用BB肥创新的亮点,其克服了一般BB肥简单掺混的先天不足,应用膜反应与团絮结构原理,针对氮、磷、钾肥料不同特性开发出三大系列涂层涂液,分别涂布于不同颗粒表面,形成一层或多层包膜,成为具有“控氮缓释、促磷增效、防钾淋失”功能,粒度均匀、色彩各异的单质改性肥料颗粒,再采用掺混工艺根据测土施肥需要科学组配与作物全生育期养分需求变化相协调的友好环境、缓释高效的肥料创新产品。几年来的示范推广实践证明,涂层缓释一次肥增产、提质、增效显著。更多还原

【Abstract】 With its unique characteristic of slow-release and higher efficiency, coated slow-release once-fertilizer, thefocus of bulk-blended (BB) fertilizers in agriculture, eliminates pre-mistakes in common BB fertilizers obtained fromsimple blending. It lays the principles of coat reaction and body frame in developing three series of coated liquid ofdifferent traits of N, P and K. It is made of one or more coats of N, P and K and has the ability to regulate the release ofN, increase the efficiency of P and at the same time prevent leaching of K. Slow-release fertilizers have same granularshape, but exist in various colors and lone states-coated N, P or K. It is a new product of soil fertilization and scientificblending of N, P and K with the needs of crops, creating a good environment and higher efficiency. The recent fieldresults show that a single application of coated slow-release fertilizers, lead to a significant increase in yield and quality,thus higher profits.更多还原
