In this paper, the cultivation and production practice of Carya illinoinensi with whole pepper in Anhui were combined, the orchard improvement and high yield techniques from aspects such as variety selection, planting density and spatial configuration, soil management, and water management were summarized. Scientifically assess the performance of different varieties under actual growth conditions, collect and sort out detailed information on different varieties of this tree species; based on soil conditions, the planting density should be reasonably determined. A planting density of 8 to 10 plants per 667 m² is appropriate. Deep ploughing for improvement and hoeing for weeding are carried out to keep the soil loose. Build irrigation and drainage facilities, optimize the water supply and drainage system of the orchard, and irrigation can be carried out simultaneously with fertilization, which is conducive to improving fertilizer efficiency. Balanced application of organic and chemical fertilizers promotes the growth and fruiting of fruit trees. By configuring pollination trees and adopting pollination methods such as manual spraying or drone spraying, the pollination efficiency can be effectively improved. It can be intercropped with short-stemmed crops such as beans and Amorphophallus konjac. Scions should be selected from 1 to 2-year-old superior variety branches that are healthy and free from diseases and pests. Bud grafting should be carried out in spring when the sap is flowing, and the survival rate is relatively high. The pruning period is preferably from winter to early spring. Reasonable pruning is conducive to improving the ventilation and light conditions of fruit trees. Practice has shown that these technologies can effectively increase the yield and quality of orchards, providing a reference for promoting the sustainable development of the Carya illinoinensis industry.
