Description
技术领域
本实用新型涉及一种颗粒肥料，尤其涉及一种除草缓释尿素。
背景技术
随着我国现代农业的逐步推进和种植规模化、集约化的转变，除草剂的使用需求逐步增大，使用量大幅增加，在农药产品中所占比例呈现加大趋势。为解决水资源缺乏和肥料资源的浪费，改善生态环境，如何提高水资源和肥料利用率是至关重要的。但是目前还没有既能够提高氮肥和水分利用率、减轻环境污染，又可消灭田间杂草、促进作物生长、增加产量、改善农产品品质、提高土壤肥力、改良土壤的增效氮肥。
实用新型内容
本实用新型的目的是为了弥补已有技术的不足，提供了一种除草缓释尿素。
本实用新型是通过以下技术方案来实现的：
一种除草缓释尿素，其特征在于：包括有多个尿素颗粒，所述多个尿素颗粒通过粘结造粒为一体，其外包裹有淀粉接枝丙烯酸钠保水层，所述淀粉接枝丙烯酸钠保水层外包裹有脲醛缓释层，所述脲醛缓释层是由脲甲醛、异丁叉二脲、丁烯叉二脲一种或其任意混合物形成，所述脲醛缓释层外包裹有除草剂层，所述除草剂层选用草甘膦、莠去津、绿麦隆、10%苯磺隆、扑草净、二氯喹啉酸、氯嘧磺隆、50%苯噻酰草胺一种或多种物料混合物。
本实用新型的优点是：
本实用新型结构设计合理，通过多个尿素颗粒粘结造粒为一体，然后再依次包裹淀粉接枝丙烯酸钠保水层、脲醛缓释层、除草剂层，既能够提高氮肥和水分利用率、减轻环境污染，又可消灭田间杂草、促进作物生长、增加产量、改善农产品品质、提高土壤肥力、改良土壤，满足了使用要求。
附图说明
图1 为本实用新型结构示意图。
具体实施方式
参见附图，一种除草缓释尿素，包括有多个尿素颗粒1，多个尿素颗粒1通过粘结造粒为一体，其外包裹有淀粉接枝丙烯酸钠保水层2，淀粉接枝丙烯酸钠保水层2外包裹有脲醛缓释层3，脲醛缓释层3是由脲甲醛、异丁叉二脲、丁烯叉二脲一种或其任意混合物形成，脲醛缓释层3外包裹有除草剂层4，除草剂层4选用草甘膦、莠去津、绿麦隆、10%苯磺隆、扑草净、二氯喹啉酸、氯嘧磺隆、50%苯噻酰草胺一种或多种物料混合物。
