| Abstract: | After many years of field experiments, optimum application rate and maximum yield application rate of maize were proposed in the blacks soil regions. The main restricting factors of soil about maize high-yield cultivation were also indicated, the results showed the effect of sub-horizon soil fertilization, subsoiling and top-dressing of PK on soil fertility and maize yield. The fertilizer requirement regularity of maize on different yields was also obtained. This paper preliminarily established the technique of building up fertility and fertilization for 14 250 kg/ha of yield and constructed the technique and demonstration of beyond 14 250 kg/ha of yield. |
