I. Corn planting methods There are many kinds of corn planting methods, such as: row spacing, wide-row planting, wide and narrow rows, and other row spacing and double seedlings. A broad row seedling planting method is introduced. Second, corn broad-line seedling planting method This planting method requires 100 cm spacing, 5 cm spacing, about 1334 holes per mu, 3 shoots per hole, and 4000 strains per mu. When planting with this method, 5-6 seeds per hole are sown, and the seeds are free to fall. They need not be too scattered or dispersed within a range of 5 cm 2 and the planting depth is 4 cm. After seedling emergence, seedlings should be settled early. The best seedlings in the three-leaf stage are the best, but they cannot be more than four leaf stage at the latest. When the seedlings are kept, 3 seedlings will be planted in each hole. The other management techniques of the corn wide-row seedling planting method are the same as the conventional planting methods. III. Reasons for high yield of corn wide-row seedling planting The reason for the increase in crop production by this method. The first is to increase the density, ventilation and light transmission is good, compared with the conventional planting method not only does not reduce the marginal effect, but also increased. Therefore, the photosynthetic productivity of the entire field can be improved. The second is that 5-6 seeds per seedling are seeded and leave large without leaving small, so that the corn group is not weak and seedlings. There is no small stick when harvesting, and the group has a large increase in yield. According to 1998, it was planted on 5 acres of land. When growing households on the 4th, the average grain yield was 500 grains and the yield per mu was 623 kg.
