优选的，所述A料各成分的质量总和为100％。
优选的，所述B料的型号为MDI、烟台万华PM200。
优选的，所述含氨基酸的生物可降解聚氨酯缓控释肥包衣材料制备工艺包括以下步骤：
S1、取质量占比为70％的A料，将该70％的A料加入到搅拌机中，取质量占比为30％的B料，放入到搅拌机中；
S2、将搅拌机温度调至65℃-70℃，并顺时针搅拌A料与B料，直至A料与B料充分混合均匀。
可实现最长300天养分缓控释，为各种农作物提供营养支持，本产品能实现植物的营养生长期，果树的越冬期，极其缓慢的释放钾元素养分≤20％(适量的钾元素能提高植物冬季抗寒能力)，剩下的80％养分留到了花期和膨果期、转色阶段，真正同时实现提高农产品品质和产量，节省用工，节省肥料。
工作原理：本工艺通过改性聚氨酯材料，使其具备前期分解慢，后期分解快的S型释放曲线，完美的适配植物生长周期对钾元素养分的需求，精准释放养分，提高肥料利用率，减少农业面源污染，采用大量疏水基团，在缓释膜表面覆盖，保证作物在营养生长期锁住钾元素养分不流失，释放量在20％以内，帮助植物提高抗寒能力，等到了膨果期，由天然氨基酸、枸杞多糖、小麦胚芽蛋白组成的亲水基团发挥水传导作用，加快养分的释放，促进果实的膨大、转色、增甜，从而促进果实品质和产量，真正同时实现提升品质、提升产量、减少人工、减少用肥量的产品，养分释放曲线是前期被向后顺延了的S型曲线，竞品一般在大棚作物的营养生长期，果树的越冬期就释放了养分，这种包衣材质只能勉强作为氮元素的缓控释技术，而不适合植物对于钾元素的需求。
最后应当说明的是，以上内容仅用以说明本发明的技术方案，而非对本发明保护范围的限制，本领域的普通技术人员对本发明的技术方案进行的简单修改或者等同替换，均不脱离本发明技术方案的实质和范围。
