What plants can interplant with corn?

Intercropping corn has many advantages. First, soil fertility can be used to improve multiple cropping index, lost sunlight can be used to reduce light leakage loss, and spatial high and low crops can be used to increase air permeability. Many crops can be interplanted with corn, so what are these crops? Let's have a look. Intercropping corn has many advantages.

First, interplant potatoes with corn.

Interplanting potato with corn is a common interplanting mode in planting industry at present, which has strong feasibility and obvious advantages, and is distributed in all planting areas in the north and south of China.

Corn is a tall crop, which likes sunshine and has strong photosynthesis. On the other hand, potatoes are drought-tolerant, like shading, and their plants are short. Therefore, the combination of these two crops, one with high altitude and the other with low altitude, not only makes full use of sunlight and space, but also inhibits weeds and reduces the occurrence of pests and diseases. They complement each other and are a pair of high-quality interplanting crops.

Second, interplanting corn with beans.

Leguminous crops such as corn, soybean and peanut are natural relatives. Because, after absorbing nutrients, corn roots can secrete a lot of carbohydrates, which can promote the propagation of rhizobia in leguminous crops such as soybeans and peanuts.

On the other hand, many rhizobia of leguminous crops such as soybeans and peanuts can fix nitrogen and provide nitrogen fertilizer for corn. Therefore, corn and leguminous crops together can promote each other's growth and increase yield.

Third, corn interplanting with pepper.

Corn plants are taller and pepper plants are relatively shorter, which belong to different levels of photosynthesis and can make full use of space.

In addition, the interplanting of corn and pepper can reduce pepper diseases and insect pests to some extent due to the shading effect of tall corn plants. The comparative experiment showed that the sunburn and virus disease of pepper were reduced by more than 70% after intercropping with corn. However, the incidence of virus disease in pepper and corn intercropping is nearly 60% lower than that in single cropping.

Fourth, interplanting corn with Chinese cabbage.

Similar to maize intercropping with pepper, maize intercropping with cabbage can also greatly reduce the occurrence of cabbage diseases. Because the shading effect of corn reduces the ground temperature, it can effectively reduce the white spot disease, virus disease and downy mildew of Chinese cabbage.

In short, there are many crops that can be interplanted with corn. When planting, interplanting can be carried out scientifically and reasonably according to the principle of blind date, so as to reduce pests and diseases, promote growth and fruit, and realize high yield and double harvest of crops.
