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。
The coated sustained-release primary fertilizer has become a new bright spot of agricultural BB fertilizer due to its unique function of sustained release and synergism. It overcomes the inherent deficiencies of simple blending of ordinary BB fertilizers, applies membrane reaction and floc structure principle, Potassium fertilizer developed three different series of coating properties, were coated on different particle surfaces, the formation of one or more layers of coating, a “controlled release of nitrogen, and promote the effectiveness of potassium, potassium leaching loss” function , Uniform granularity, different color of single modified fertilizer particles, and then use the blending process according to the needs of soil testing and chemical fertilization needs of crops during the whole growth period to meet the needs of changes in nutrient-friendly environment, slow release and efficient fertilizer innovative products. Demonstration over the past few years proved that the coated slow-release fertilizer production, quality, efficiency significantly.
