Abstract:: The high-quality seed of Armeniaca sibirica was used as test materials.Via orthogonal test design,the branch grafting technology optimization was studied,in order to put forward the key technology of branch grafting with low cost and high efficiency and provide theoretical basis and technical support for optimizing and perfecting the rapid propagation technology system of Armeniaca sibirica high-quality seed.The results showed that all treatments had significant difference in effect of branch grafting.Seed tree age,cutting position and scion slope length had significant influence on the effect of branch grafting.All treatments had significant difference in efficiency of branch grafting.Cutting position and scion slope length had significant influence on the efficiency of branch grafting.No.7 treatment which meant 1.5 cm of scion slope length,one-year-old seed tree,the lower branch of cutting position and 4 cm of grafting height had the best branch grafting effect,and its survival rate,shoot diameter and length were 98.67%,7.38 mm and 94.32 cm,respectively.The branch grafting efficiency of No.7 treatment took 29.67 minutes.The production cost could be saved by 31.7% on average.To synthesize the branch grafting effect and efficiency,No.7 treatment was the highest survival rate,the best growth effect,the fastest efficiency and the lowest cost.This treatment was the optimal combination and could be applied in the promotion of Armeniaca sibirica high-quality seed.
