| Abstract: |
| To obtain the best cultivation method of maize，and achieve high and stable yield of spring maize，
Split Plot Design with main treatments of 4 different row spacing and vice treatments of 4 different density was
used，taking Guidan 162 as materials，to study the yield of corn under different densities and row spacing. The
results showed that，density and the interaction of density and row spacing had very significant effects on corn
yield. The grains per ear and yield of maize showed well in the density of 3 000 plants/667m2 under the row spacing
of 60 cm，70 cm and 80 cm×40 cm，showed well in the density of 3 500 plants/667m2 under the row spacing of
90 cm×40 cm. The cultivation model of high yield was the row spacing of 80 cm×40 cm with the density of 3 000
plants/667m2. In the actual production，proper cultivation method in accordance with varietal characteristics may
improve the maize yield. |
