高效涂层尿素是广州氮肥厂研制的一种胶态状溶液,它含有硼、锌、锰、钼、铁等多种微量元素,把它深敷在尿素的表面,形成一层包膜,使尿素成为缓效、长效、多效的复合氮肥。1994年在互助县的21个乡镇不同作物上进行试验、示范,具有明显的增产增收效果,深受广大农民欢迎,为大面积推广打下了良好的基础。 一方面具有明显的增产作用;在其它管理栽培条件均一致的条件下,小麦上亩用13公斤涂层尿素作基肥,亩用15公斤普通尿素作基肥为对比;甘蓝型油菜上亩用8公斤涂层尿素作基肥,2.5公斤涂层尿素作种肥,2.5公斤涂层尿素作追肥,与亩用10公斤尿素
High-efficiency coated urea is a colloidal solution developed by Guangzhou Nitrogen Fertilizer Plant. It contains many kinds of trace elements such as boron, zinc, manganese, molybdenum and iron and deposits it deeply on the surface of urea to form a coating Urea slow, long-acting, multi-effect compound nitrogen fertilizer. In 1994, experiments and demonstrations were carried out on 21 crops of different townships in Huzhu County, demonstrating obvious effects of increasing yield and increasing income. They were well received by farmers and laid a good foundation for the promotion of large-scale popularization. On the one hand, it has a significant yield-increasing effect; under the same conditions of other management and cultivation conditions, 13 kilograms of coated urea on wheat was used as basal fertilizer and 15 kilograms of common urea was used as basal fertilizer on the one hand; Coated urea as a base fertilizer, 2.5 kg of coated urea as a kind of fertilizer, 2.5 kg of coated urea for top-dressing, and mu with 10 kg of urea
