| Abstract: | The comparison experiment was condueted between normal nitrogen mixed fertilizer and special mixed fertilizer with slow-release nitrogen for corn planting. The fertilizers were applied as basal manure, which was confected with coated urea by macromolecule resin, slow--release ammonia bicarbonate and normal urea containing urease inhibitor. The results showed that the yield of corn applied mixed fertilizer with slow-release nitrogen was 5.36-8.33% up on that of mixed fertilizer with normal nitrogen, fertilizer absorbance increased by 1.71%- 4.04%, and the level of nutrient content of functional parts was higher at later stage. |
