First of all, the intercropping of pepper and corn can reduce the incidence of sunburn of pepper fruit diseases! Because the corn plants are relatively tall, when the corn grows tall in summer, it can block the pepper to a certain extent, reduce the direct sunlight time, and the effect of preventing sunburn is obvious; On the other hand, because corn plants are separated by peppers, corn plants have more living space and get more direct sunlight, so the corn cob planted is full of seeds and has high ear yield. This interplanting method is very suitable for areas with high summer temperature!
Second, the harm of pests to pepper can be reduced by interplanting pepper and corn! This mainly uses the sweetness of pests, such as aphids, tobacco insects and noctuids, which are common in agricultural production to harm sweet crops! And the corn here is a sweet crop!
Pepper was damaged by aphids in the early stage, and planting corn next to it could attract aphids to transfer to corn plants. Pepper will face the harm of caterpillars in the late growth stage, and if there are corn plants, it can also attract caterpillars! Generally speaking, the probability of pest damage to pepper is reduced, which lays a good foundation for the growth of pepper.
Thirdly, the intercropping of pepper and corn improves the utilization rate of fertilizer. In fact, in the process of intercropping, there is almost no need to consider the fertilization problem of corn, which can be carried out in accordance with the fertilization standard of pepper, because pepper is originally a cash crop, farmers have invested a lot in management, and using all kinds of fertilizers with good quality can completely meet the needs of corn, and the quality of corn planted is absolutely good!
Fourthly, the intercropping of pepper and corn can change the microclimate environment in the field to some extent. On the one hand, corn grows fast and its plants are tall, which can play a shading role in the later stage, obviously reducing soil moisture evaporation and regulating field temperature. Low field temperature is not conducive to the occurrence of pests, so it has a certain preventive effect on pests such as red pepper spiders. On the other hand, the well-developed root system of maize plants is also beneficial to the regulation of soil moisture, which can not only conserve soil moisture, but also alleviate the waterlogging during the summer rainstorm, which is of great benefit to pepper to resist the adverse external environment!
Corn changes the temperature and humidity in the field, making the environment more conducive to crop growth. It can effectively alleviate the problems of falling flowers and fruits caused by high temperature, which can be described as killing two birds with one stone!
How to interplant corn in pepper field? Intercropping corn in pepper fields is actually very simple. For example, the peppers planted here are all planted in strips, and the rows of corn should be controlled at 2-4 meters in advance, which can give full play to the advantages of planting corn!
Intercropping corn in pepper field, corn planting can not affect pepper, we must grasp the row spacing, different varieties of pepper row spacing is not the same!
What are the precautions for pepper and corn intercropping? First of all, regarding the selection of interplanting corn varieties, it is suggested that farmers choose varieties with strong plants, dense leaves and large ears, so that on the one hand, they can obtain higher corn yield, on the other hand, they can also play a good shading role!
Second, the choice of pepper varieties. It is suggested that farmers choose early and middle maturity varieties, so that the harvest period of pepper is earlier than that of corn, and the advantages of interplanting can be better played!
Third, although pepper is the main crop after intercropping, the daily management of corn is still indispensable. For example, squatting at seedling stage can make maize take root deeper, and the basal internodes of plants are strong and sturdy, which can enhance the drought resistance and lodging ability in the later stage. The better the corn grows, the greater the influence on pepper.
Fourth, although intercropping the two can reduce the occurrence of pests and diseases, it does not mean that it will not happen. It is still necessary to prevent and control pests and diseases in daily management, and spray protective fungicides such as thiophanate-methyl, zineb and carbendazim in the field every 15 days; For pests, some imidacloprid, thiamethoxam, emamectin benzoate and beta-cypermethrin can be added when spraying, which has a certain preventive effect!
The interplanting of corn and pepper has little effect on the planting amount of pepper, but the overall control of field temperature, moisture and light is realized with the help of corn, which is equivalent to indirectly improving the stress resistance of pepper and improving the quality and yield of pepper. In addition, the corn harvested in the field has added extra income to farmers. This planting method has indeed brought great economic benefits to farmers.
The intercropping mode of pepper and corn has alleviated the frequent occurrence of pests and diseases caused by high temperature and drought in summer in some high altitude areas! It is also suggested that farmers can try planting according to the planting environment conditions in their own areas!
