How to plant seeds of Luohansong?

Luohan pine is an evergreen coniferous tree of Luohan pine family, which is cultivated in all provinces south of the Yangtze River and is also distributed in Japan. Now it is mainly used for potted ornamental plants in the north and south of China, which has a very high ornamental value. At present, the engineering seedlings with a breast diameter of more than 10 cm on the market mainly rely on imports. Let's take a look at how to plant seeds of Luohansong.

Growth habit of Luohansong

Luohansong likes warm and humid climate, weak cold resistance, strong negative resistance, sandy loam with good drainage, strong adaptability to soil, and can survive on saline-alkali soil. It has strong resistance to sulfur dioxide, hydrogen sulfide, nitrogen oxide and other pollution gases and strong resistance to diseases and insect pests. China is produced in Jiangsu, Zhejiang, Fujian, Anhui, Jiangxi, Hunan, Sichuan, Yunnan, Guizhou, Guangxi, Guangdong and other places. Cultivated in the garden as an ornamental tree, there are very few wild trees.

Seed preservation of Pinus elliottii

After the seeds of Luohansong are collected, they should be placed in a dry and ventilated place as far as possible. the best condition for storing seeds is not to have too strong light. Too hot and humid environment will also have an impact on the preservation of Luohansong seeds. The temperature difference will cause the seeds to germinate ahead of time. The best way to store the seeds is to seal them and put them in the refrigerator. The seeds preserved in this way will neither germinate ahead of time nor lose moisture from the seeds.

Pinus elliottii seed sowing

Soak the seeds for about 4 days before sowing, let them fully absorb water, and soak them in warm and cold boiling water, so that the seeds have a higher germination rate. When sowing, sow seeds at a spacing of 20 cm per row and 10 cm per plant. When sowing, bury the seeds according to the depth of the seeds, and then cover them with grass to moisturize the seeds. Spray water to the seed once a day after sowing. Remove the grass cover 8-9 days after sowing, protect yourself from the sun and do not expose it to the sun.

Seedling raising technique of Pinus elliottii

The seeds of Pinus elliottii will germinate about 40 days after sowing. We should pay attention to the gap between the seedlings. If the seedlings are too dense, take the soil and transplant them to the vacant places. Be careful not to let the new seedlings be drenched with water to ensure the survival rate of the seedlings. When the seedlings grow to about 6 leaves, you can properly pour some biogas to dilute the water, it is recommended not to use chemical fertilizer. Due to the slow growth of seedlings, 1 year later, the plant row spacing 20x20 cm, or moved into a 15 cm nutrition bag, 1 plant in each bag. One year later, the seedlings were replanted with row spacing of 1x1 meters. After 3 years of seedling cultivation, the seedling height was 11.3 meters, the crown width was 1 square meters, and the crown was tower-shaped, which could be used in garden or continue to grow large seedlings.
