Study on the Preparation and Fertilizer Efficiency of the Slow Release Macromolecular Fertilizer Special for Potato
The 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∶P_2O
5
∶K_2O=1∶0.8∶0.4) can satisfy the nutrition requirement of potato 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 potato by 15.89%
the macromolecular fertilizer with livestock and normal potato-fertilizer(urea+livestock+calcium superphosphate) increased the yield of the potato by 53.29% and 46.71%
respectively.
