With the warm weather, many farmers' friends have begun spring plowing. Many areas will be sowing spring corn in about a month. Corn has always been one of the main food crops planted by farmers in China, and corn intercropping is also a planting pattern often used by many farmers.

In order to promote agriculture scientifically, let's see which crops can be intercropped in corn fields. Intercropping is a frequent cropping method used by growers. Intercropping can maximize the use of land, but there are still certain requirements that need to be met in order to achieve good intercropping. The first thing to do is to pay attention to the matching of root systems, planting shallow and deep roots to fully utilize soil nutrients. Match crops with each other to avoid low light. Staggered harvest times can extend the growth of late crops. Crops are mutually beneficial; some crops release some toxic substances during growth and are not suitable for planting together. Also, it is more beneficial to stagger the fruiting parts of the crops as much as possible and not have the same leaf size and growth direction. Soybeans:Soybeans should be the first thing that comes to the mind of many friends, because the requirements of corn and soybean sets are almost fulfilled. Corn and soybean growth height and harvest time is different, soybean root system can produce rhizobia, rhizobia can fix nitrogen. It can be said that the two sets of seeds should be the best choice. Peanuts:Corn and peanuts can also be planted in sets, spring corn and spring peanuts have certain advantages in the growth height, which can improve the light utilization rate and ventilation of the field. And peanuts are relatively shade-tolerant, corn and peanuts are relatively drought-tolerant, set seeding is also a good choice.

Set seeding peanuts, it is best to choose more shade-tolerant varieties, which is more conducive to improving the effect of set seeding. Sweet potatoes:Corn and sweet potatoes can also be planted in sets, but not many people are currently planting this way. Sweet potato and corn planting can make full use of the edge of the corn field, give full play to the utilization value of the land, and the harvest period of sweet potato is relatively late. After the corn is harvested, sweet potato can continue to grow. Fungi:Some areas will be corn and fungi set seeding, mainly because the fungus is more shade-tolerant, suitable for growth under the corn leaves, fungi collection time is short, very suitable for corn vigorous growth period set seeding. But there are many technical requirements for corn and fungi set seeding.
