The invention discloses an efficient sweet cherry fence type grafting and symbiotic cultivation technology. According to the technical scheme, fence type cultivation is utilized. The method comprisesthe steps of large seedling cultivation and transplanting before grafting, trunk grafting and cultivation of lateral branches after grafting. According to structural indexes of trees obtained after symbiotic cultivation, the height of the trees is 2.5-3.0 m, the vertical section of each trunk is 40-50 cm high, the horizontal section of each trunk is 1.8-2.3 m long, 8-12 back branches grow on eachtrunk, the back branch spacing of each trunk is 10-15 cm, the length of the back branches on each trunk is smaller than 2.0 m, the diameter of base parts of the back branches on each trunk is smallerthan 4 cm, and the effect fruit and branch proportion is 98%. The invention further discloses application of the technology in the field of cherry grafting and cultivation field. The problem that in atraditional fence type cultivation technology, back branches of cherries are not balanced in growth is solved, seedling planting is completed within two years, and the technology has the advantages that the number of layers of tree structures is small, growth is balanced, the back branches are strong, the yield is high, harvesting is early, the cherry variety is good, and mechanical harvesting isfacilitated.
