Problems solved by technology

However, the production of bonsai has strict requirements and a long cycle. It needs to be twisted and shaped to promote the formation of lateral buds and then climb the side branches to form them. It takes 2-3 years to form, which cannot meet the market's demand for bougainvillea bonsai seedlings. It is not conducive to the construction of ecological civilization and beautiful China

Embodiment 1

[0030] On February 5, 2015, 15 8-year-old Dahong Bougainvillea with a ground diameter of about 6cm and a ground diameter of about 6cm were selected as the mother plants of the high-altitude layering. On these mother plants, the robust growth and no pests were selected at a distance of 10cm from the mother plant. 4-year-old branches with a diameter of 3 cm and a length of 50 cm, beautiful shape, and flexible branches were circumcised. The circumcision depth reached the phloem, and the circumcision width was 1.8 cm. The cortex and cambium were scraped clean. Apply perlite sterilized by 800-fold potassium permanganate solution and mixed with 1.0mg / mL LIBA to the wound, with a thickness of 3cm, and then use a longitudinally cut mineral water bottle to cover the outside of the matrix. Use the longitudinal section and both ends of the mineral water bottle Tape tightly. During the rooting period, check the humidity of the substrate every 7 days. The humidity should be kept at about 5...

Embodiment 2

[0032] On July 10, 2015, 15 8-year-old Dahong Bougainvilleas with a ground diameter of about 7cm were selected as mother plants for high-altitude layering, and 4-year-old, 4-year-old, with a diameter of 4cm, length 100cm, beautiful shape, flexible large branches are girdled, the first girdling mouth is 20cm away from the mother plant, and the second girdling mouth is 40cm away from the first girdling mouth. The circumcision depth reaches the phloem, the circumcision width is 2cm, and the cortex and cambium are scraped clean. Apply peat soil sterilized by 800 times potassium permanganate solution and mixed with 500 times ABT rooting agent to the wound, with a thickness of 3.5 cm, wrap it with plastic film, and then tie it tightly with a rope. Check the substrate humidity every 10 days during the rooting period. The humidity should be kept at about 50%. When the humidity is too low, inject water into it with a syringe. The girdling place began to take root in 30 days, and the r...

Embodiment 3

[0034] On December 30, 2015, 15 9-year-old, robust and free from diseases and insect pests, with a ground diameter of about 8cm, were selected as mother plants for high-altitude layering. On these mother plants, 5-year-old plants with a diameter of 5cm, length 100cm, beautiful shape, flexible large branches are girdled, the first girdling mouth is 10cm away from the mother plant, and the second girdling mouth is 50cm away from the first girdling mouth. The circumcision depth reaches the phloem, the circumcision width is 2.4cm, and the cortex and cambium are scraped clean. Spread the yellow soil mixed with 500 times of ABT rooting agent through 500ppm carbendazim solution disinfection on the wound, with a thickness of 3cm, wrap it with a plastic film, and then tie it tightly with a rope. Check the humidity of the substrate every 15 days during the rooting period. The humidity should be kept at about 50%. When the humidity is too low, inject water into it with a syringe. The gi...

Abstract

The invention discloses a method for air-layering propagation of a bonsai seedling of bougainvillea spectabilis. The method comprises the following steps: selecting a 4-to-5-year-old appearance-beautiful easily-flexible bough with a diameter of about 3 to 5 cm and a length of about 50 to 100 cm from an 8-to-9-year-old bright-red bougainvillea spectabilis mother plant with a ground diameter of about 6 to 7 cm and no diseases and pests, carrying out girdling, scraping a bark layer and a cambium layer, and compressing a wrapping substrate mixed with a disinfectant and a rooting agent on the position of a cut, carrying out seal packaging by using a plastic film or a longitudinally-cut mineral water bottle, carrying out air layering for about 26 to 37 days, allowing a cut of girdling to grow a root system, allowing the substrate to be filled with the root system in 50 to 60 days, carrying out propagating on the mother plant for 3 to 4 months, carrying out separation with the mother plant, carrying out transferring into a clay pot with an opening diameter of about 25 cm, and placing the clay pot at a shade place for about 15 days, wherein the survival rate is up to 98% or above. The method provided by the invention has less investment, easy operation and significant effects, can rapidly obtain the bonsai seedling of the bougainvillea spectabilis, is rapid in shaping, shortens the period of culturing, and is insusceptible to seasonal restrictions.

Description

technical field [0001] The invention belongs to the technical field of high-altitude bonsai seedling breeding, in particular to a method for propagating bougainvillea bonsai seedlings by high-altitude layering. Background technique [0002] Bougainvillea spectabilia Willa belongs to the genus Bougainvillea of ​​the family Mirabilis. It is the main landscaping plant in the tropical and subtropical regions of southern my country, and it is also the city flower of many cities. Bougainvillea has high ornamental value, bright colors, and long duration.
