A slow release macromolecular fertilizer containing diverse nutrition was synthesized by condensation reaction between the homemade low molecular urea-formaldehyde and the compound of potassium dihydrogen phosphate and phosphoric acid.The nutrition of the fertilizer(N∶P2O5∶K2O=10∶7.6∶1.5) can satisfy the nutrition requirement of maize growth in the field experiment by adjusting the proportion of raw materials.The field experiment results showed the macromolecular fertilizer increased the yield of the maize by 16.56%

the macromolecular fertilizer plus livestock and the SV corn-fertilizer plus livestock increased the yield of the maize by 56.51% and 49.11%

respectively.
