什么是树脂包衣尿素?为什么能够缓释?树脂包衣肥料在包衣加工设备完全封闭下,将尿素和复合肥进行包衣,使表面形成一层树脂膜,从而达到氮素（N.P.K）缓慢释放的效果.通过加工过程中对包衣材料的配方的调整,包衣温度、包衣时间的控制可以形成包衣厚度不同、包膜破裂的时间和速度不同,可以控制包衣尿素的释放天数（60天、90天、120天、180天and so on）,对于氮肥的利用率起到控制和提高的作用.树脂包衣复合肥可直接用在草坪和花卉上.缓/控施肥只要有以下几种类型：1、包膜（裹）型缓/控释肥料.2、合成型微溶态缓释肥料.3、生物化学抑制性长效肥料.肥料包衣加工机械的制造是项目的关键,目前包衣加工设备有喷动床、流化床和转鼓等设备,加工采用的机械类型,加工时的温度、气速、喷头的类型和状态,都能够影响肥料的质量和生产成本.喷流式包衣机包衣效果很好,转鼓包衣机不能用于可控肥料包衣.树脂使用新塑料制成颗粒,塑料可用塑料棚膜或地膜、包装材料都可以.据我们实验,使用回收的废旧塑料,杂质会影响溶出效果.采用树脂包衣技术生产的树脂包衣肥料所具备的控释、缓释、长效三大特点注定它从根本上避免了传统肥料存在的肥料浪费、养分流失、土壤及地下水污染等弊端,提供给作物平缓而且源源不断的养分供给,肥料养分释放期与作物生长期近乎完美匹配,所以单纯依靠加大普通化肥施肥量并不能得到更高的产量.控释肥料氮素利用率可以达到60%以上,1KG控释肥料相当于1.5KG普通肥料.    树脂包衣尿素不但能够提高肥料利用率、提高作物产量,而且还有以下优点：一次施肥能满足作物整个生长期的养分需求,省工省力；可根据土壤状况和作物品种配制各种专用肥,施用方便；包衣尿素重施不会发生盐害,不伤苗、不伤根；减少对地下水、地表水和空气的污染,提高产品品质,符合无公害、健康食品的要求.

What is the resin coated urea? Why can release? Resin coated fertilizer in the coating processing equipment will be completely closed, urea and fertilizer is coated, the surface to form a layer of resin film, so as to achieve nitrogen ( N.P.K ) slow release effect. Through the process of coating material for regulating formula, coating, coating time temperature control can be formed by coating thickness of different, capsule rupture time and speed, can control the release coated urea days ( 60 days, 90 days, 120 days, 180 days, and so on ) for nitrogen fertilizer utilization rate to control and improve the function of. Resin coated compound fertilizer can be used directly on the lawn and flowers. Slow / controlled fertilization as long as there are several types: 1 ( wrap ), coated slow / controlled release fertilizers. Synthesis of 2, slightly soluble state of slow release fertilizer. 3, inhibition of long-term biochemical fertilizer. Fertilizer coating processing machinery manufacturing is the key to the project, the present coating processing equipment spouted bed, fluidized bed and drum equipment, processing machinery used in the type, processing the temperature, gas velocity, nozzle type and status, can affect the quality and production costs of fertilizer. Jet type coating machine coating effect is very good, drum coating machine can not be used to control fertilizer coating. The use of new plastic resin particles, plastic or plastic film, available plastic film packaging material can be. According to our experiments, the use of recycled plastics, impurities will affect the dissolution results. The resin coating technology in the production of resin coated controlled release fertilizer with slow release long-acting, three big characteristics doomed it fundamentally avoid the traditional fertilizer fertilizer waste, nutrient loss, soil and groundwater pollution etc, provide crop smoothly and everfount nutrient supply, nutrient release period and the growth period of crops near perfect matching, so simply relying on increasing general chemical fertilizer quantity and can't get higher yield. Controlled release fertilizer nitrogen use efficiency can reach above 60%, 1KG is equal to 1.5KG ordinary fertilizer controlled release fertilizer. Resin coated urea can not only improve the utilization rate of the fertilizer, increasing crop yield, and it has the following advantages: a fertilizer can meet crop nutrient demand of whole growth period, saving labor and time; according to the soil and crop varieties of preparation of a variety of special fertilizer, convenient application; coated urea again no salt, not to hurt the seedling, not to hurt root; reduction of groundwater, surface water and air pollution, improve product quality, meet the pollution-free, health food requirements.
