Problems solved by technology

[0003] At present, most of the horned melons are propagated by seeds, but the maturity periods of the horned melons are inconsistent, and manual seed collection is time-consuming and laborious, and it takes 3 to 4 months for seed propagation to emerge from the nursery. Moreover, the offspring of seed propagation are highly differentiated, and it is difficult to maintain the female parent. Good traits
The conventional cutting propagation method is greatly affected by the season, the rooting rate is unstable, and the survival rate is not high, which is not conducive to the large-scale production, development and application of horn melon propagation

Embodiment 1

[0024] In mid-June, 2015, the strong branches with a diameter of 1.0 cm that were erect or oblique on the mother plant of the horned melon were selected as layering materials. Then mix fresh yellow heart soil, coconut peat, and sawdust in a ratio of 2:1:1 by volume to prepare layering matrix, and spray and soak it with 0.5% potassium permanganate solution for disinfection. Before layering, keep the matrix in hand to form a ball , No dripping humidity. Then use a girdling knife to perform girdling at a distance of 15 cm from the base of the branch. The girdling point is 2.5 cm away from the lower internode, and the girdling width is 1.0 cm. Use a sharp grafting knife to scrape off the cambium to avoid injuring the xylem. A brush dipped in a concentration of 100ml / L ABT6 root powder solution to smear the girdling mouth. Then apply an appropriate amount of moist matrix to the girdling opening, then wrap it with a transparent plastic film, and tie the upper and lower ends tightly...

Embodiment 2

[0026] In mid-July, 2015, strong branches with a diameter of 1.2 cm, erect or oblique, were selected as layering materials on the mother plant of the horned melon. Then mix fresh yellow heart soil, coconut peat, and sawdust in a ratio of 2:1:1 by volume to prepare layering matrix, and spray and soak it with 0.8% potassium permanganate solution for disinfection. Before layering, keep the matrix in hand and form a ball , No dripping humidity. Then use a girdling knife to perform girdling at a distance of 10 cm from the base of the branch. The girdling point is 3.0 cm away from the lower internode, and the girdling width is 1.5 cm. Use a sharp grafting knife to scrape off the cambium to avoid injuring the xylem as much as possible. A brush dipped in a concentration of 100ml / L ABT6 root powder solution to smear the girdling mouth. Then apply an appropriate amount of moist matrix to the girdling opening, then wrap it with a transparent plastic film, and tie the upper and lower end...

Embodiment 3

[0028] In the first ten days of August, 2015, strong branches with a diameter of 1.5 cm, erect or oblique, were selected as layering materials. Then mix fresh yellow heart soil, coconut peat, and sawdust in a ratio of 2:1:1 by volume to prepare layering matrix, and spray and soak it with 1.0% potassium permanganate solution for disinfection. Before layering, keep the matrix in hand to form a ball , No dripping humidity. Then use a girdling knife to perform girdling at a distance of 20 cm from the base of the branch. The distance between the girdling point and the lower internode is 2.0 cm, and the girdling width is 1.2 cm. Use a sharp grafting knife to scrape off the cambium to avoid injuring the xylem as much as possible. A brush dipped in a concentration of 100ml / L ABT6 root powder solution to smear the girdling mouth. Then apply an appropriate amount of moist matrix to the girdling opening, then wrap it with a transparent plastic film, and tie the upper and lower ends tigh...

Abstract

The invention discloses a method for air layering propagation of calotropis gigantea. The method is characterized by comprising the steps of branch selection, substrate preparation and processing, air layering, layering post-management and in-vitro transplanting; upright or inclined robust branches with the diameter being 0.5-1.5 cm are selected on seed trees of the calotropis gigantea, girdling is performed, a prepared substrate A is bound on a girdling opening, layering post-management is performed, and finally in-vitro transplanting culture is performed to obtain high-quality calotropis gigantea calotropis gigantea seedlings. According to the method, layering rooting is rapid, the rooting rate is 100%, the transplanting survival rate reaches up to 92% or above, seedlings are robust and high in quality, and calotropis gigantea seedlings with the good-character female parent can be reserved within a short period of time; meanwhile, seed transplanted seedlings flower and fruit before seed seedlings, high-quality, efficient, large-scale and rapid development of calotropis gigantea can be promoted, and good economic, social and ecological benefits are achieved.

Description

technical field [0001] The invention belongs to the field of plant vegetative propagation, and relates to a seedling cultivation method, in particular to a method for high-altitude layering propagation of horned melon. Background technique [0002] Croissant melon ( Calotropis gigantea (L.) Dry. ex Ait. f. ) is an upright shrub belonging to the family Ascariaceae, and it has various utilization values ​​such as fiber, medicine, and energy. The fiber of croissant melon can be used in textile production, rope making, papermaking, artificial cotton and sack weaving, etc., and can also be used as a potential water-absorbing and oil-absorbing material, thermal insulation material and buoyancy material. Its roots, stems, leaves and fruits can be used medicinally. It has anti-inflammatory, antibacterial, phlegm-resolving and detoxifying effects. It is used for the treatment of diseases such as leprosy, asthma, cough, ulcers and tumors. Its milk is rich in cardiac glycosides It ha...
