Sago Palm, Latin name Cycas revoluta Thunb. In fact, generally 15 to 20 years old trees can flower. If the cultivation is well, it can flower once a year, in the south, and when the growth environment is good, you can see flowers every year.
Sago Palm stems are terete, not branched from Sago palm. Cauline persistent leaf base and leaf scar, scaly. Leaves grow from stem apex, pinnatifid compound leaves, thick leathery and hard, pinnatifid. Lobules are linear, initially rolled inwards, laterally oblique, slightly v-shaped, margin reversed, apex acute, back densely rusted villi, base lobules spiny. Sago Palm is dioecious, flowering in June to August, male conidia cylindrical, small spore leaves woody, densely yellow-brown tomentose, abaxially with many drug capsules. The female conidia is oblate, the megaspore leaves are broadly ovoid, the upper part is pinnately divided, and there are 2 ~ 4 naked straight ovules on both sides of the lower part. Seeds mature in December, seeds large, ovate and slightly flattened, reddish brown or orange when ripe.
Sago Palm prefers warm and humid environments, does not tolerate cold, grows very slowly, and has a life of about 200 years. Trees more than 10 years old in the tropical and subtropical south of China bloom and bear Fruit almost every year, while Sago palm cultivated in the Yangtze River valley and other parts of the north often do not bloom all their lives, or occasionally bloom and bear fruit.
Sago Palm likes light, iron, slightly shade tolerant. When planting in an open field in the Shanghai area, warm measures such as straw wrapping should be taken in winter. Sago Palm prefers rich, moist and slightly acidic soils, but also tolerant to drought. Sago Palm grows slowly and blooms for more than 10 years.
There are 17 species of Sago Palm in the world, which are distributed in tropical and subtropical regions such as east Asia and southeast Asia, Oceania and Madagascar. China has 8 species, produced in Taiwan, Guangdong, Hainan, Fujian, Guangxi, Yunnan, Sichuan and other provinces.
In Fujian, Guangdong, Guangxi, Jiangxi, Yunnan, Guizhou and the eastern Part of Sichuan and other places are mostly planted in gardens, Jiangsu, Zhejiang and north China provinces and regions are mostly planted in pots. In winter, Sago Palm is placed in greenhouses for wintering. They are also found in southern Japan, the Philippines and Indonesia. Type specimens are collected from Japan.
1. Tillering propagation: Tillering was cut from tree trunks and planted in sandy loam with rows 20-30cm apart, plant spacing 10-15cm apart and overlying soil 6-8cm apart. It was easy to survive under semi-shade conditions.
2. Trunk cutting propagation: Cut the trunk into about 10cm sections, bury them in sandy soil, cover the soil with 4-6cm soil, water them frequently and keep them wet, and then plant them after the cadres send out new buds.
3. Sowing propagation: The seeds should be collected at the end of autumn and sown as they are picked. The covering soil should be about 3cm deep, and germinate after about 2 weeks at 30 ~ 33℃ and high temperature. Seedlings grow slowly and take 2 to 4 years to transplant.
Garden use: Sago Palm trees are graceful, vigorous and plain, with large and beautiful leaves and green tops all the year round, with unique ornamental effect. If arranged in the Garden and large venue, it can achieve a solemn and solemn effect. It is arranged in the center of the Flower bed, making people feel serene.
