一种利用谷氨酸发酵废弃物制备的复合肥料
摘要：
本发明属于氨基酸废弃物处理的环保技术领域，公开了一种利用谷氨酸发酵废弃物制备的复合肥料，其按照如下步骤制备而得：步骤1）制备氨基酸螯合颗粒；步骤2）制备尿素-腐植酸络合物；步骤3）制备复合肥料。本发明复合肥料和常规的复合肥搭配，养分配比合理，增产明显，商品性好，并且减少了常规无机肥的使用量，节约了成本，可显著提高经济效益；同时，避免了无机肥大量使用造成的土壤恶化。
摘要（英）：

The invention belongs to the technical field of environmental protection of amino acid waste treatment, and discloses a compound fertilizer prepared from glutamic acid fermentation waste, which is prepared according to the following steps: 1) preparing amino acid chelated particles; (2) preparing a urea-humic acid complex; and (3) preparing a compound fertilizer. The compound fertilizer of the invention is matched with the conventional compound fertilizer, has reasonable nutrient ratio, obvious yield increase and good merchantability, reduces the usage amount of the conventional inorganic fertilizer, saves the cost, and can obviously improve the economic benefit; at the same time, soil deterioration caused by a large amount of inorganic fertilizer is avoided.
