Abstract: In order to make the Ulmus pumila cv.Jinye growing into commodity nursery stock in the same year and shorten the cycle of cultivation, the grafting skill with germination branches under low temperature was researched and developed on the basis of bud grafting. The writer adopted “grafting skill with germination branches” from different grafting time processing on the survival rate, seedling rate and seedling growth in through the contrast test. It selected the best grafting time. The results show that: graft survival rate of “grafting skill with germination branches” and “hot sticky skin” is not obvious difference, but the seedlings growth of “grafting skill with germination branches” can be achieved in the requirements. Combined with seedling growth, we sure April 15 to May 30 is the best grafting time for “grafting skill with germination branches”.
