The invention discloses a method for interplanting pepper in wheat ridges. The method comprises the following steps of 1, variety selection: the pepper interplanted in the wheat ridges are mainly used for supplying markets in autumn and summer seasons, and the pepper varieties with medium-late maturing, heat resistance, large fruits, good commodity features and high yield can be selected; 2, seedling sowing: germination and sowing are performed in medium and later period of March or seedlings are directly sown in a plastic arch greenhouse; 3, field planting: the pepper interplanted in the wheat ridges is planted in a mode that two lines of wheat are sown at the area of 2-2.2m of a large field, and a hollow field space with the width of 0.8-1m is remained between adjacent ridges for planting the pepper; and 4, harvesting: the pepper interplanted in the wheat ridges is harvested and sold in the beginning period of July, the harvesting period in July and August are in high-temperature season, the fruits are fast in growth, dark green and hard in quality and need to be harvested during light, part of the red fruits can be harvested when the price is higher, and the pepper plants are pulled out in medium-later October. The method for interplanting the pepper in wheat ridges provided by the invention can be used for obtaining the pepper variety which is high-temperature-resistant, anti-virus, strong in growth state, concentrating in fruiting, large in fruit, thick in fruit wall, cold-resistant and increased in yield, can improve the commodity grade, facilitate disease prevention and the continuous sell of the products, and avoid the falling of flowers, fruits and leaves, thus greatly improving the local economic benefits.
