Introduction of Luo Hansong
Podocarpus is a kind of pine tree, also known as Luo Hanshan, Changqing Luohanshan, Laoshan, Chinese pine, Xianbai, Luohanbai, Jiangnanbai, is an evergreen tree, can be up to 18 meters, usually trimmed to keep low Leaves alternate, arranged in a spiral shape, also divided into male and female, the seedlings are larger than the seeds, mature red, plus green seeds, like the bald monk wearing red robes, hence the name Luo Hansong. Luo Hansong is common in South China, including Hong Kong. Because the potted planted Chinese pine is available for viewing, its wood is used for construction, medicinal and engraving, so its value is very high. As a result, many Hong Kong Lo Hansong were illegally deforested by illegal immigrants from the interior.
Morphological characteristics of Podocarpus
The crown is broadly oval. Leaves lanceolate, apex pointed, base cuneate, ribs bulging on both sides, dark green surface, grayish-green on the back, sometimes white powder, tightly arranged, spirally alternate. Dioecious or occasionally the same strain. The seeds are ovate, with black arils, which are born on the succulent and swelled seedlings. The seeds are dark red and sweet and edible. The flowering period is May, and the ripening period is October. Common cultivars are Pinus sylvestris var. sylvestris, with narrow leaves, apex gradually narrowing and growing tip shape; column crown Podocarpus, small leaves, apex pure or round; lobular pine, leaves densely at the tip of the branch, spiraling, It is narrow, apex obtuse; short-pointed leaves of Pinus sylvestris, leaves extremely short; locusts, with white spots on the leaves. According to the morphological characteristics, it can be judged that Podocarpus belongs to the yew class. Podocarpus is a national second-class protected plant, but the state protects the wild Podocarpus germplasm in the original forest. The Lohan pine in the city is basically an artificially cultivated offspring with little biological significance. Just like metasequoia and ginkgo, the artificially cultivated offspring are no longer in protection. Of course, they still play an ecological role as green trees, and they cannot be cut down at will. There is no illegal tendency for Luo Hansong to transplant as a landscape tree.
The ecological habits of Podocarpus
Johanson is produced in Jiangsu, Zhejiang, Fujian, Anhui, Jiangxi, Hunan, Sichuan, Yunnan, Guizhou, Guangxi, Guangdong, and other provinces, and is cultivated in the provinces south of the Yangtze River. Japan also has a distribution. It is mainly used for potted plants in the north and south. Sexually sunny, but also slightly shade-resistant. It requires mild and humid climatic conditions, no hot and humid summer heat, and no cold frost in winter. In the case of light frost, the young leaves and autumn shoots will all be yellow. Therefore, except for the subtropical regions of South China and Southwest China, it is not resistant to severe cold, so it can only be potted in North China. It is required to be rich in humus, loose and fertile, and well-drained slightly acidic culture soil. The leaves are yellowed in alkaline soil, with slow growth and long life, up to several hundred years old, even thousands of years old.
Semi-positive tree species. It grows well in a semi-shade environment. Like warm, moist, and fertile sandy loam, it can also grow in coastal plains. Not tolerant of severe cold, so it can only be potted in North China. long life.
Cultivation techniques of Podocarpus
Hi warm and humid and semi-yin environment, cold resistance is slightly poor, afraid of water and strong light, requiring fertile, well-drained sandy loam. Transplanting is best in spring from March to April. Seedlings need to bring soil, and the seedlings can be soiled with pots. Water should be poured after planting. Keep the soil moist during the growing period. In the hot summer season, you need to put a half shade to maintain. Fertilize once every 2 months. In winter, the potted plants should be protected against cold, and the pots can be buried in the soil and reduced in watering.
