一、什么是涂层尿素?所谓涂层尿素就是指在生产尿素过程中,把一种特制的涂层溶液,均匀喷洒在尿素颗粒的表面,制成一种外观为橙黄色圆型小颗粒的复合氮肥。据由间测试证明,尽管涂层尿素的有效氮素含量与普通尿素相同,但由于涂层颗粒结构稳定,不易结块,所用涂层溶液中又含有适量的胶态物质,及一下比例的硼、锌、锰、铁等微量元素,所以它能发挥缓减氮素分解、释放,增加对土壤的吸附力,以及增强农作物对氮的吸收利用率和减缓氮素在土壤中的淋失、挥发、反硝化等作用,发挥缓效、长效、
First, what is coated urea? The so-called coated urea refers to the production of urea in the process, a special coating solution, evenly sprayed on the surface of urea particles, made of a look of orange-yellow round small particles Compound nitrogen fertilizer. According to the inter-test, it is proved that although the effective nitrogen content of coated urea is the same as that of ordinary urea, due to the stable structure of the coating particles and the difficulty in agglomeration, the coating solution used also contains an appropriate amount of colloidal substance and a certain proportion of boron , Zinc, manganese, iron and other trace elements, so it can play to reduce nitrogen decomposition, release, increase the adsorption capacity of the soil, and enhance crop nitrogen absorption and utilization and slowing the nitrogen in the soil leaching, volatile , Denitrification and other effects, play a slow, long-term,
