Description:
The invention relates to the technical field of non-metallic compounds, in particular to the field of urea formaldehyde fertilizer slow/controlled release chemical fertilizers, and particularly relates to a papermaking wood pulp by-product lignin sulfonate/urea formaldehyde fertilizer and a reactive extrusion granulation process. And reacting until the system becomes thick, then extruding by a twin-screw extruder to obtain a strip-shaped product, drying, and pelletizing to obtain the papermaking wood pulp by-product lignin sulfonate/urea formaldehyde fertilizer columnar particles. According to the papermaking wood pulp by-product lignin sulfonate/urea formaldehyde fertilizer columnar particles prepared by the invention, lignin sulfonate molecules are introduced into a urea formaldehyde macromolecular main chain to reduce the polymerization degree and the crystallinity of a urea formaldehyde fertilizer, so that the nitrogen nutrient release rate of the fertilizer is adjusted, and the defect of slow nutrient re
