How to propagate passion fruit? A detailed introduction to common propagation methods
Passion fruit is a fruit with very high nutritional value, and passion fruit juice, dried passion fruit, and other products made from passion fruit are all very popular. The planting area of passion fruit in our country is still expanding, but many people also do not know how to propagate it to expand the planting area. In fact, passion fruit has three propagation methods, and everyone needs to master them. Below, the editor brings you the propagation methods for passion fruit. Let's take a look!
1. Seed propagation
One of the most commonly used propagation methods for passion fruit is seed propagation, which generally begins in spring and autumn each year. First, take the seeds out of plump, juicy fruits free of pests and diseases, then wash the seeds clean with clear water. Then soak the seeds in warm water at about 40 degrees for 15-16 hours, after that remove them and soak them in a thiophanate-methyl solution for about 2 hours to disinfect and sterilize the seeds. After soaking, dry them, then wrap the seeds in a wet cloth and place them at a temperature of about 26-28 degrees for germination treatment. During germination, turn the seeds once about every 6 hours, then wash the seeds once every other day. When about 85% have sprouted white, sowing can begin.
2. Cutting propagation
Cutting propagation is also a basic propagation method. It begins around November each year. First, select semi-lignified branches that grow thick and strong, bear many fruits, and have not been harmed by pests or diseases. After cutting off the branches, cut them into small sections of about 10 cm, keeping 1-2 buds on each section. Then remove about 3/5 of the leaves to prevent excessive water evaporation and reduce the survival rate of the cuttings. Then disinfect and sterilize the small sections and do a good job of promoting germination. Finally, prepare the cutting substrate and insert the cuttings vertically into the substrate, keeping 1/3 of the cutting above the ground. After cutting, water thoroughly, set up rainproof and sunshade measures, and control watering according to the weather and soil moisture to keep the soil moist. About one month after cutting, they can take root and sprout.
3. Grafting propagation
The last one is grafting propagation. The time for grafting propagation of passion fruit is usually in spring each year. First, select a passion fruit variety with strong resistance as the grafting rootstock. The rootstock seedlings should begin to be cultivated one year before grafting, and then when the rootstock diameter reaches 5 mm, grafting can be done at the proper time. The conditions for selecting the scion are the same as for selecting cuttings. First select the scion well, then handle the scion according to the requirements of cutting propagation. Note that the lower part of the scion should be cut at a slant to facilitate grafting. After preparing the scion, cut the rootstock at a position about 12 cm above the ground, then make a slant cut of about 2 cm, attach the scion, and treat the cut well. The temperature during grafting must not be too high. One week after grafting, pay attention to whether it has survived; if it has not survived, graft again.
What to note in grafting propagation is that after grafting, direct sunlight should be prevented, then water appropriately according to weather changes, and during the grafted seedling stage keep the soil moist to improve the survival rate of grafting. No matter which propagation method is used, management must be strengthened after the seedlings are established to ensure the survival rate. Avoid seedling failure, which would affect planting benefits. That is all for today's introduction. This article is for reference only. Thank you for reading and supporting.
