Rapid propagation method of Bougainvillea spectabilis Willd

Abstract

The invention relates to a rapid propagation method of Bougainvillea spectabilis Willd. The method specifically includes the steps of collecting cuttings, processing the cuttings, soaking the cuttings with a rooting solution and a sterilizing solution, preparing nutritious sterilizing wrapping mud, soaking the cuttings with the mud, wrapping the cuttings, carrying out cultivating on cultivation discs, performing water and fertilizer management, and carrying out transplanting to obtain finished-product seedlings. The rapid propagation method has the advantages that deep soil is collected, the rooting solution and the sterilizing solution are prepared into a mixed solution, and the mixed solution is mixed with the soil and stirred to prepare the nutritious sterilizing mud; the Bougainvillea spectabilis Willd is prevented from being infected during the propagation process, the cuttings can contact with the rooting solution for a long time to allow the cuttings to root as fast as possible and to have developed roots; rapid propagation of the Bougainvillea spectabilis Willd can be performed all the year round, fast propagation is achieved, the cuttings can root in 5-6 days generally, and transplanting can be performed in about 10 days; and meanwhile, infrastructure investment is not needed, and the method is low in investment, simple in process, easy to operate, evident in effect and worthy of energetic popularization and application.

Problems solved by technology

[0003] The commonly used propagation methods of Bougainvillea include cuttings and high-pressure propagation, while cuttings are mostly used in large-scale cultivation. The cutting season is generally carried out from March to June. In areas that are neither south nor north, the survival rate of cuttings is generally low

The main reason is that there are problems in soil sterilization and disinfection, and there are also problems in the selection of branches in cuttings, heat preservation, moisture retention, transplantation, and slowing down of seedlings.
