How does Luohansong breed?

Luohansong, also known as Luohanshan, evergreen Siraitia, Taxodium, Pinus elliottii, etc., is an evergreen coniferous tree of the family Luohansong, which likes warm and humid climate, weak cold tolerance, potted ornamental plants in North China, and has high ornamental value. China is distributed in Jiangsu, Zhejiang, Fujian, Anhui and other places. Let's take a look at how Luohansong propagates.

Sowing and propagation of Pinus elliottii

Luohansong began to bear fruit at the age of 10 years or so, and the phenomenon of big and small years was not obvious. It is best to sow seeds as they are picked and not to be stored for the summer. Soak the seeds for several days first, and then strip sow or sow on demand after the seeds are fully absorbed and swollen. The sowing depth is better to cover the seeds, cover the grass to moisturize after sowing, and spray water once a day. If sowing in the open field, it is also necessary to cover grass to survive the winter in the southwest. Pot sowing is needed in other areas, and after sowing, it is moved to a low-temperature greenhouse to overwinter. The seedlings can be unearthed in 8 to 10 days. Remove the cover grass and shade immediately after being unearthed. Do not expose yourself to the sun. For potted plants, the terminal buds can be removed at the age of one year to promote the germination of many branches. generally, seedlings of one and a half to two years old can be planted in pots and begin to shape curved branches. Planting plants, generally 3-4-year-old seedlings, it is appropriate to bring soil balls out of the nursery.

Striping propagation of Pinus elliottii

Striping propagation of Luohansong should be carried out before and after the sting of the solar term in spring (that is, early March). Use the dwarf Luohan pine ball to select branches that are slightly smaller than chopsticks close to the ground, cut the branches oblique with a knife on the side of the ground at the base, and insert an inch-long piece of bamboo into the incision horizontally, insert a small stick next to it, tie it up gently with plastic tape, then cover the cut with loose soil and gently compact it. Cover it with dead grass to keep it moist. After March, the branch can take root at the cut. The Autumn Equinox used shears to cut and transplant from the base of branches after solar terms.

Cuttage Propagation of Pinus elliottii

1. Softwood cuttings: the softwood cuttings of Luohan pine were carried out from mid-late May to early July in the first half of the year, and from mid-late August to mid-late September in the second half of the year. Seedlings planted in the first half of the year should pay attention to preventing high temperature burns and diseases. Seedlings planted in the second half of the year should pay attention to heat preservation and anti-freezing in the middle and later periods. The time to uncover the shading net is late November, and the time to uncover the shading net in dry years can be extended to late December.

2. Hardwood cutting: hardwood cutting refers to the method of cutting the sturdy branches completely lignified in the previous year when the sap has not yet flowed from February to March in early spring. Early spring hardwood cutting should pay attention to improve the soil temperature and control the air temperature in the greenhouse. In short, whether it is softwood cuttings or hardwood cuttings, we should not only do a good job in the disinfection of cuttings and soil, but also regulate the temperature, humidity and light of the seedbed. In addition, in order to improve the survival rate of seedling cuttings, some measures should be taken to promote rooting.
