Wheat-pepper-corn intercropping model bears fruit

□Henan Daily All-Media Reporter Tian Ming

On December 20, 2024, Liu Jianfeng, a big grower in Wawuliu Village, Fenjian Township, Jian\’an District, Xuchang City, was busy drying the last batch of peppers, with joy on his face: \”Last year, I saw College studies The students intercropped corn and peppers, and the harvest was good. This year, I planted 10 acres of corn and peppers with them. From the net income of these 10 acres, I earned almost 30,000 yuan! ” p>

The courtyard Liu Jianfeng mentioned is the Xuchang Jian\’an Maiyu Science and Technology Hospital of Henan Agricultural University. On December 25, 2024, at the Maiyu Science and Technology Yard, Shao Ruixin, a professor and doctoral supervisor at the College of Agriculture of Henan Agricultural University, told reporters that their team had been stationed here for two consecutive years to conduct research on the wheat-pepper-corn intercropping model. This model better solves the conflict between grain and economic land. It is a planting model that achieves double harvests of grain and cash crops, thereby achieving an increase in grain output and economic benefits per unit area.

Hu Xinru, a graduate student at the College of Agriculture of Henan Agricultural University, said that in 2024, they set up three corn sowing dates for the wheat-pepper-corn intercropping model at the Maiyu Science and Technology Yard. According to field test data, corn Planting after the wheat harvest has the highest annual yield and economic benefits. Each mu of land can harvest 588.6 kilograms of wheat, 641.4 kilograms of corn, and an additional 1073.3 kilograms of fresh peppers (Chaotian peppers). Compared with the traditional annual wheat-corn monoculture planting model, the economic benefits of intercropping corn and pepper are obvious, and the net income can increase by more than 3,000 yuan per mu.

More valueIt is worth mentioning that the intercropping planting model also promotes the green development of agriculture. Through reasonable crop layout, the corn belt and pepper belt were rotated in the second year, which effectively reduced the use of chemical fertilizers and pesticides, and also improved soil quality and crop yield, laying a solid foundation for sustainable agricultural development.

Liu Tianxue, a professor at Henan Agricultural University and a member of the corn expert steering group of the Ministry of Agriculture and Rural Affairs, said that this planting model not only improves the multiple cropping index and output efficiency of the land, but also promotes ecological complementarity between crops and reduces It is a vivid practice of agricultural modernization to eliminate the occurrence of pests and diseases. The next step should be to continue to deepen the structural reform of the agricultural supply side, optimize the planting structure, increase investment in agricultural science and technology, and promote more efficient planting models such as corn and pepper intercropping to take root, so that agriculture can become a promising industry and farmers can be more productive. Good land to increase income and become rich.
