Sapodilla propagation techniques include grafting and cutting methods
Sapodilla is originally a tropical fruit from the Americas, and now it is also cultivated to a certain extent in tropical regions of China such as Guangdong and Yunnan. It gets its name because the fruit looks very much like a human heart. Sapodilla has very high nutritional value, so its planting area is also constantly expanding. So how should we propagate sapodilla when growing it? Below, the editor brings you the propagation methods for sapodilla. Let's take a look!
1. Seed propagation
Seed propagation is the most basic propagation method for sapodilla. Sapodilla ripens around September each year. After the fruit ripens, take the seeds out of the fruit, then select and remove shriveled seeds and seeds with wounds. Wash the sticky pulp off the surface of the seed coat of the remaining seeds with clean water. Then dry the seeds in the shade and store them in a ventilated place until sowing the next year. Before sowing, pay attention to doing the work of promoting germination and disinfection to improve the seeds' germination ability. When sowing, the temperature is best controlled at 25 degrees. When the temperature is suitable, strengthen management, and generally about one month after sowing they can germinate.
2. Cutting propagation
Cutting propagation is best carried out in summer, because the temperature and humidity in summer are more suitable for the growth of cuttings. We should choose a robust, high-yielding tree as the mother plant. Then cut off robust terminal young branches free of pests, diseases, and wounds. Appropriately apply rooting agent and healing agent to the cut to promote wound healing and improve the rooting ability of the cuttings. Each cutting should be kept at about 13 cm. After completing the pre-insertion preparation work, insert it vertically into the nursery bed. After insertion, control the temperature of the nursery bed at about 26-27 degrees. However, note that sapodilla cutting propagation roots very slowly, and if managed improperly it may even fail to root.
3. Layering propagation
Layering propagation is one of the most commonly used propagation methods for sapodilla. It is carried out every spring. First choose robust branches grown within two years. Control their diameter at about 2 cm, then carry out girdling at a position about 22-24 cm from the top of the stem on the branch. The depth of girdling mainly depends on the size of the branch. When white material is found after peeling to the xylem, clean it off completely. Then use tape to wrap wet clay soil, and try to use a container with good permeability to wrap the girdled part, because with strong permeability, rooting will be faster. Tie both ends tightly to prevent it from coming loose and losing effectiveness. Under normal management, roots will form in 2-3 months.
The above is a brief introduction to sapodilla propagation methods. Sapodilla propagation methods also include grafting, and grafting propagation is rather troublesome to handle. Therefore, everyone needs to have certain skills. When propagating, we should reasonably choose the propagation method according to skills, preparation, and so on, to ensure successful propagation. That is all for today's introduction. This article is for reference only, and we hope it can help everyone!
