The utility model discloses a kind of crossbreeding devices of Gypsophila paniculata, including temperature control box body, the both sides of temperature control box body are provided with illumination component, the inner side wall of temperature control box body is provided with floor height adjusting component;Illumination component, including slide bar one and spring, slide bar one is respectively slidingly connected at the both sides of temperature control box body, spring is sleeved on the side wall of slide bar one, one end of slide bar one is fixedly connected with fluorescent lamp, the utility model relates to Gypsophila paniculata hybridization technical field;The Gypsophila paniculata crossbreeding device of being set, can be adjusted work to the illumination position of Gypsophila paniculata, so that different growth stages and different planting area Gypsophila paniculata plant can receive uniform and suitable intensity illumination, in Gypsophila paniculata seedling stage, illumination position can be adjusted low and adjusted to relatively mild angle, avoid strong light sunburn seedling, promote its vigorous growth;To flower bud differentiation stage, can accurately focus illumination to the flower bud part of plant.

The application provides a grafting method for improving the flowering rate of bougainvillea spectabilis, which comprises the following steps: selecting bougainvillea spectabilis branches, cutting the branches into a culture medium as rootstocks, sterilizing before grafting; arranging the scions into single-bud stem segments, treating the single-bud stem segments with bacteriostatic nutrients as scions A; transplanting and planting the scions A into the culture medium after grafting to obtain primary grafting seedlings; taking the branches of the primary grafting seedlings, arranging the branches into single-bud stem segments, cutting the single-bud stem segments from the lower part of the stem segments, and cutting the stem segments into bevels as scions B after treating the single-bud stem segments with bacteriostatic nutrients; transplanting and planting the scions B into the culture medium after grafting, transplanting the scions B into a planting area after successful planting, and culturing the scions B to obtain target bougainvillea spectabilis; and the bacteriostatic nutrients comprise tetramycin, carbendazim and triacontanol. After secondary grafting, the grafted bougainvillea spectabilis has the advantages of high grafting survival rate, large number of flowers, long new branch length in the full-bloom period, and effective improvement of the flowering rate and flowering quality of the bougainvillea spectabilis.
