Prunus trilobata with spring hardwood cuttings into the seedling rate, but to the next spring transplanting seedling time is too long; summer softwood cutting management is difficult, seedling rate is not high. In recent years, we use summer and autumn hardwood cutting, received good results. Practices are as follows: 1. Need to use the article cuttings matrix (1 humus and 1 mixture of sand); promote rooting hormone; pruning shears; shading materials. 2. Cuttings selected from the mother plant on the election 1 to 2 years without strong pests branches, cut into 3 to 4 buds for a cuttings, the top of the bud in the top 1 cm above the cut, the bottom of the bud 0.5 cm below the cut.
