Current year cuttage and flower growing for bougainvillea speetabilis

Abstract

The invention discloses a current year cuttage and flowering method for bougainvillea speetabilis, and relates to the technical field of greening tree seedling growing. The current year cuttage and flowering method is characterized by comprising the following steps of selecting the species, putting the species in a greenhouse throughout the winter for retaining leaves, performing cuttage on seedlings with the leaves in the spring, and performing greenhouse management and outdoor management, wherein the step of putting the species in the greenhouse throughout the winter for retaining the leaves comprises the substeps of when the outdoor temperature is lower than -2 DEG C in the winter, putting the bougainvillea speetabilis with the leaves in the greenhouse, controlling the temperature in the green at 2-8 DEG C, and supplementing water once every 10-15 days; the step of performing cuttage on the seedlings with the leaves in the spring is executed in the early March, and the annual bougainvillea speetabilis which is fully lignified is subjected to cuttage; during the greenhouse management, the light transmittance is kept at 35-45 percent; during the outdoor management, the seedlings subjected to the cuttage are transplanted to a place, which is shaded by 30 percent, outside the greenhouse for transitioning for two weeks. The bougainvillea speetabilis cultivated by the current year cuttage and flowering method can adapt to cold weather, is high in survival rate and grows well, and the current year cuttage and flowering method is favorable for saving the cost.

Description

Technical field: [0001] The invention relates to the technical field of raising seedlings of greening tree species, in particular to a method for raising flowers by cutting bougainvillea in the same year. Background technique: [0002] Bougainvillea spectabilis Willd., aliases: bougainvillea, three-leaf plum, Maobaojin, bougainvillea, bougainvillea, bougainvillea, leaf plum, paper flower, South American mirabilis, etc. An evergreen climbing shrub. It likes warm and humid climate, not cold-resistant, and likes sufficient light. Miraraceae, Bougainvillea. According to the prior art, Bougainvillea is difficult to carry out local seedling cultivation in areas with relatively cold climate, and seedlings need to be introduced from the southern area. The seedlings just introduced from the south are difficult to quickly adapt to the northern climate, so the survival rate is not very high, even if they survive. It is also difficult for young seedlings to grow robustly, and the pri...

According to the prior art, Bougainvillea is difficult to carry out local seedling cultivation in areas with relatively cold climate, and seedlings need to be introduced from the southern area. The seedlings just introduced from the south are difficult to quickly adapt to the northern climate, so the survival rate is not very high, even if they survive. It is also difficult for young seedlings to grow robustly, and the price is relatively high
