The invention relates to a high-strength triangular plum-blossom-shaped cement soil mixing bearing pile and a forming method thereof. The high-strength triangular plum-blossom-shaped cement soil mixing bearing pile is good in perpendicularity, incline resisting capability and full in full-load bearing capacity. The cement soil mixing pile comprises a cement soil mixing pile, two end faces and a cement soil mixing pile body are formed by connection of three plum-blossom-shaped petals, and one or more concrete cement piles are positioned in a high-strength triangular plum-blossom-shaped cement soil mixing bearing pile body. The high-strength triangular plum-blossom-shaped cement soil mixing bearing pile has the advantages that a pile foundation of the triangularly distributed plum-blossom-shaped cement soil mixing pile is large in bearing capacity, bearing and supporting points are triangularly distributed, and the pile foundation is good in stability; when the pile foundation formed by the triangular plum-blossom-shaped petals is positioned in a soft soil foundation, the three plum-blossom-shaped petals identical in inclined angles act on a wall of the soft soil foundation like three projected ejection posts, so that the cement soil pile is ensured not to incline but perpendicularly stand in the soft soil foundation; due to the fact that a three-axis drilling rod sinks along a guiding frame, stirs and sprays cement paste at the same time, and the sinking direction and the stirring direction are opposite, so that the cement paste and soil can be fully mixed integrally, and high strength of the cement soil pile is ensured.

The invention discloses a bougainvillea spectabilis breeding method and belongs to the technical field of nursery stock propagation. The bougainvillea spectabilis breeding method includes the steps of standardized planting and management of bougainvillea spectabilis female parents and high-altitude layering of bougainvillea spectabilis child branches. According to the bougainvillea spectabilis breeding method, high-altitude layering is performed on the bougainvillea spectabilis child branches through the standardized planting and management of the bougainvillea spectabilis female parents, planting can be achieved in the current year, seedlings can be sold in the current year, and the supply period of the seedlings is greatly shortened; meanwhile, the high-altitude layering technological parameters are optimized, the rooting percentage of the obtained high layered branches is high, the transplanting survival rate of the high layered seedlings is high, and the problems that the supply period of the bougainvillea spectabilis seedlings is long, the seedling breeding conditions are critical, and the seedling breeding cost is high are solved.
