Abstract
The invention relates to the technical field of production of agricultural product fertilizer, and particularly relates to a bi-enzyme polypeptide urea and a preparation method thereof. The preparation method comprises the main steps of (1) preparing fungus liquid; (2) processing raw materials; (3) prilling; and (4) drying: drying mixed particles in a 50-60DEG C drying system for 10-15 minutes. The polypeptide urea prepared by the method has good solubility and more nutrients, can be absorbed by crops favorably, has low fertilizer application rate, and improves the yield of the agricultural products.
Description
Technical field
The present invention relates to agricultural product technical field of fertilizer production, more particularly, to a kind of pair of enzyme polypeptide carbamide and its preparation side
Method.
Background technology
Carbamide is a kind of high concentration nitrogenous fertilizer, belongs to neutral quick-acting fertilizer it can also be used to produce multiple compound fertilizers.Because having
Nitrogen content is high, is in granular form fertilising conveniently, the advantages of not remaining any harmful substance in soil in measures for increasing agricultural output, quilt
Using the most extensive.Peptide urea is in carbamide forming process, adds metalloproteases, concentrate through vaporizer in urine
Pelletize forms.With the addition of metalloproteases is to greatly promote growth and development of plants.Through test, apply peptide urea, plant
5-15 days maturations typically can be shifted to an earlier date, and chemical fertilizer utilization ratio and crops quality etc. can be improved.But weak point sprays polypeptide
Carbamide, the element absorption such as nitrogen that crops discharge to it, phosphorus, potassium is not comprehensive, and molten speed is slow, causes urea desorption column low, fertile
Effect runs off seriously, causes crops prevalence high, promotes to develop the situation but do not increased production.
