Abstract

The invention relates to a special long-acting slow release fertilizer for corn and a preparation method thereof. The long-acting slow release fertilizer provided by the invention contains the following components, by weight: 27% of nitrogenous fertilizer active principle, 14% of phosphatic fertilizer active principle, 4% of potash fertilizer active principle, 9.2-9.7% of bentonite, 0.7-0.9% of long-acting compound fertilizer additive. The bentonite contains 85-90% of montmorillonite; and the long-acting compound fertilizer additive comprises components of 2-8 parts of hydroquinone, 3-25 parts of dicyandiamide, 0.1-0.8 part of complex rare earth and 70-95 parts of zeolite powder. Xinjiang corn applied with the special long-acting slow release fertilizer for corn shows active straw mature, grows strong and has strong resistance, full seed, large ear, insusceptibility to lodging, salt alkaline bearing capacity and early bloom time. Nitrogen utilization rate and phosphor utilization rate are increased substantially; and the fertilizer is safe to people, livestock and crop and has no residue in soil or crop.
