Slogan of soybean and corn interplanting

When intercropping in three rows, the row spacing is 33 cm and the hole spacing is 40-50 cm; When intercropping in two rows, the row spacing is 45 cm, the hole spacing is 27-33 cm, and each hole has 3 seedlings. When interplanting corn and soybean, it should be noted that corn is a tall crop, while soybean is relatively short, so the combination of high and low planting can improve the utilization rate of light energy, but it will affect each other in the interplanting process. In order to solve these contradictions, it is necessary to design a good planting model. In the interplanting of corn and soybean, besides the selection of maturity and resistance, marginal effect should also be considered.

First, the best row spacing of soybean and corn interplanting

1, the row spacing is 33 cm, and the hole spacing is 40-50 cm when intercropping in three rows; When interplanting two rows in a strip, the row spacing is 45 cm, the hole spacing is 27-33 cm, and three seedlings are planted in each hole.

2. When interplanting corn and soybean, it should be noted that because corn is a tall crop and soybean is relatively short, although this high and low planting can improve the utilization rate of light energy, it will still affect each other and have a negative impact in the interplanting process. For example, corn leaves will block soybeans and affect their light, which will make it difficult for soybeans to grow and develop normally and will not have ideal yield. Soybean and corn will compete for land, fertilizer and water, which will affect the normal growth and development of corn, and corn may also reduce production. In order to solve these contradictions, it is necessary to design a good planting model.

3. Besides maturity and resistance, marginal effect should also be considered when interplanting maize varieties, and high-quality varieties are more suitable for interplanting. When selecting soybean varieties, it is necessary to consider the rapid development of seedlings at seedling stage and form seedling racks before corn ridge sealing to reduce the influence of corn on them.

Second, the benefits of soybean and corn interplanting

1. Intercropping soybean in corn field shows complementary advantages in planting structure. The heights of corn and soybeans are different. Intercropping corn and soybean not only makes rational use of space, but also improves the utilization rate of land and light energy.

2. Because soybean is a short-day crop, planting soybean between corn rows can play a good role in shielding sunlight and ventilation. Soybean is also a nitrogen-fixing crop, which can fix nitrogen by about 3 kilograms per mu, which can reduce the application amount of corn chemical fertilizer and the yield of corn will not be reduced.

3. The root system of maize is relatively developed, which can absorb nutrients and water well when it goes deep into the soil, while the root system of soybean is relatively shallow, and its drought tolerance is poor. At the same time, soybean is a waterlogging-tolerant crop. Therefore, intercropping between corn and soybean can help soybean absorb water in the soil and bring benefits to corn.
