Abstract

The invention relates to a seaweed synergia compound fertilizer and a preparation method thereof. The method comprises the steps of: preparation of seaweed synergists, preparation of a granulating material, preparation of urea meltwater, granulation and the like. According to the fertilizer and the method, a fusing urea guniting process is combined with a drum granulating process to produce the seaweed synergia compound fertilizer, and due to the promotion effect of active ingredients in a seaweed synergia solution on crops during growth, the inhibiting effect of the active ingredients on soil urease, and the influence of the active ingredients on chemical valence bond features of urea, the crop yield is increased, the fertilizer utilization rate is increased, the nutrient loss is reduced, and the secondary pollution is avoided. The fertilizer product disclosed by the invention has the characteristics of being wide in material sources, free from deliquescing, convenient to deliver, apply and produce, simple in process, low in cost, beneficial to industrial generalization, and the like, and has a wide application prospect in production.

Description

【Technical field】 [0001] The invention belongs to the technical field of fertilizers. More specifically, the present invention relates to a glutamic acid synergistic compound fertilizer, and also relates to a preparation method of the glutamic acid synergistic compound fertilizer. 【Background technique】 [0002] Compound fertilizer is an important fertilizer variety in my country. At present, the fertilizer compounding rate in my country is about 32%, and the physical output is about 55 million tons. A large number of studies have shown that the nutrient utilization efficiency of existing compound fertilizers is low. For example, the seasonal utilization efficiency of nitrogen is about 30%, that of phosphorus is about 25%, and that of potassium is about 45%. Therefore, how to improve the nutrient utilization efficiency of fertilizers has always been a hot spot of concern and research. In recent years, there are mainly the following ways to improve the utilization rate of f...
