To overcome the difficulties in some fruit trees rapid propagation, a partial-sunlight intermittent misting system was designed and used in the new shootings of the sweet cherry dwarf rootstock Gisela 6 with softwood cutting. In conditions of controlling the environmental factors accurately in the greenhouse, the rooting rate of the new shoots reached to 93.66% in 45 days and the average number of roots was 7.29. The survival rate of the new shoots was up to 95%. Compared with the traditional tissue culture and rapid propagation, the technique can shorten the propagation period and cut down the cost distinctively.
