The invention discloses a stingless Sichuan pepper introduction and grafting method, and belongs to the technical field of grafting of the Sichuan pepper. According to the method, the four steps of 1, field selection and soil preparation; 2, grafting and cultivation; 3, strain cultivation and 4, relay intercropping are used for achieving introduction and grafting of the stingless Sichuan pepper. By using the stingless Sichuan pepper introduction and grafting method provided by the invention, a grafting survival rate is increased to 94%-97% from 31%, and morbidity and mortality are relatively low. By using the planting mode of the method, the Sichuan pepper can grow robustly, and both increment and branch growth are significantly improved, thus being beneficial to bearing fruit in advance and implementing early harvesting. According to the method provided by the invention, the yield of green Sichuan pepper is 10500-10890 kg/667m<2>, an output value reaches 1968.23-2060.00yuan/667m<2>, and thus economic benefit is significant.
