High-pressure propagation method [ Illustrated Science popularization ]
If you want to learn about the topic of flower propagation, the high-pressure propagation method [ Illustrated Science popularization ], the editor of this site will introduce it to everyone next.
Some新手 flower friends don't understand what high-pressure propagation is. High-pressure propagation is a type of layering propagation, which is divided into high-pressure and low-pressure. To put it simply, low-pressure propagation means directly pressing the branches on the ground, as shown in Figure 1. And high-pressure (Figure 2) is a method of wrapping the injured or girdled branches with sand and soil (other media) for propagation because some plant branches are not easy to bend.
Let's talk about the concept of high-pressure propagation and then look at specific cases:
High-pressure is also called aerial layering. Created by China, it is also known as Chinese layering. It is suitable for tall or not easy to bend plants and is mostly used for precious tree species (Camellia, Osmanthus, Longan, Lychee, Manilkara zapota, etc.). Select 1-3-year-old branches, ring剥 2-4 centimeters, scrape off the cambium layer or make longitudinal cuts to create wounds, wrap the injured part with plastic wrap, split bamboo tubes, or ceramic pots, tie them tightly, fill with moss or fertilized soil, water regularly to keep moist, and cut off the new plant after rooting.
Let's look at a specific case of high-pressure propagation of bougainvillea:
The case uses paper towels, but in practice, you can use plastic bags, disposable cups, and other containers filled with soil or other media, all of which can be used. Flower friends should not be confined to the case, as the case is just one method of high-pressure propagation of bougainvillea. Our purpose in presenting it is to provide a process reference for flower friends.
1. Girdle, about 0.5-1 cm wide. Scrape the cambium layer clean from the branch.
2. You can apply a rooting powder solution to the wound.
3. Wrap the paper towel around the wound, tie it securely, and then wrap it with plastic wrap and tie it up (using paper towels is just one of the few methods; most often, soil is wrapped around the wound and then covered with a plastic bag, as seen in the second photo below, an example of high-pressure propagation of roses).
4. Pour water into the paper towel to thoroughly soak it. Add water to the paper towel as needed later.
5. Wrap the paper towel with paper to block light.
6. After about a month, the roots develop, and the branch is cut off and potted with the paper towel to slow down the seedlings.
The above is the detailed explanation of the high-pressure propagation method [ Illustrated Science popularization ], hoping this article can bring you help in green plant management!
