Abstract：The effects of fertilizing different release patterns of nitrogen(N) fertilizers[treatment 1(CK):superphosphate and potassium chloride,treatment 2:coated granular fertilizer in low nitrogen,treatment 3:controlled-releasing fertilizer in low nitrogen,treatment 4:formula fertilizer in low nitrogen] and sowing at the same time on corn yield and N production efficiency under no-tillage subsoiling in the the clay lime concretion black soil with high fertility retention capacity. The results showed that the seeding density should be enhanced with fertilizing and sowing at the same time,and the difference of distance between the plants was large. Dry weight curve of different types of fertilizers were basically the same,all increased with the growth period,and the treatment 6 had the largest value,second was the treatment 5. Compared with the CK,N fertilizer increased maize yield,the order was treatment 6 >treatment 2 >treatment 5 >treatment 4>treatment 3>CK,the yield of treatment 6 was significantly higher than the other treatments, which increased by 71. 60% compared with CK,there were no significant difference among treatment 2, 3,4. Overall,the treatment 6 was the best.
