How to plant the latest seeds of Luohan pine?

Podocarpus is an evergreen coniferous tree of Podocarpus aromatica, cultivated in all provinces south of the Yangtze River, distributed in Japan, mainly used for potted viewing in the north and south, with extremely high ornamental value. At present, the engineering seedlings with DBH of more than 10 cm on the market mainly rely on imports. Let's take a look at how Podocarpus seeds are planted!

Podocarpus growth habits

Podocarpus like warm and humid climate, cold resistance weak, strong shade resistance, like good drainage of wet sandy loam, strong adaptability to soil, saline-alkali soil can also survive, sulfur dioxide, hydrogen sulfide, nitrogen oxide and other pollution gas resistance is strong, resistance to diseases and insect pests is strong, I made in Jiangsu, Zhejiang, Fujian, Anhui, Jiangxi, Hunan, Sichuan, Yunnan, Guizhou, Guangxi, Guangdong and other places, cultivated in gardens as ornamental trees, wild trees are very few.

Podocarpus seed preservation

Podocarpus seeds in the collection down, as far as possible placed in a relatively dry and ventilated place, the best storage conditions for seeds is not to have too strong light place, too hot and too humid environment will also have an impact on the preservation of Podocarpus seeds, temperature difference is too big to make Podocarpus seeds germinate ahead of time, the best way to store Podocarpus seeds is sealed in the refrigerator, so that the preserved seeds will not germinate ahead of time nor let the seed moisture loss.

Podocarpus seed sowing

Soak the seeds for about 4 days before sowing, so that they can fully absorb water, you can use warm and cold water to soak, so that the seed germination rate is higher. When sowing, sow in rows spaced 20 cm apart and each plant spaced 10 cm apart. When sowing, bury the seeds deep enough to bury the seeds, and then cover them with grass to keep them moist. Seed sowing water spray seeds once a day, seed sowing after 8 to 9 days to remove the grass cover, do a good job of sun shade, do not expose it to the sun.

Techniques for Seedling Raising of Podocarpus sinensis

Podocarpus seeds will germinate about 40 days after sowing. Attention should be paid to the spacing between seedlings. If there are too dense places, transplant the seedlings with soil to the vacant places. Be careful not to let the newborn seedlings drench with water to ensure the survival rate of seedlings. When the seedlings grow to about 6 leaves, you can properly sprinkle some methane dilution water. It is recommended not to use chemical fertilizer. Due to the slow growth of seedlings, transplant after 1 year, plant spacing 20 x 20 cm, or move into 15 cm nutrient bags, 1 plant per bag. After one year, transplant once again, plant spacing 1 x 1 m, seedling height can reach 1~1.3 m, crown width can reach 1 square meter, crown into tower shape, can be used as garden or continue to breed large seedlings.
