Hi light, slightly resistant to half shade. Hi warm, not very cold the Shanghai area exposed to planting, the need to take precautionary measures such as straw dressing in the winter. Hi fertile, moist, and the cycad --- lower part of the old leaves without pruning the form of a slightly acidic soil, but tolerates dry. Slow growth, flowering plants more than 10 years. The cycad the beautiful plant morphology, flexible blade, the more shade-tolerant, both outdoor placed, but also indoor ornamental because of its growth rate is very slow, so the price is higher. Su Tiexi slightly damp soil environment, its growth rate is very slow, so be sure to pay attention to the amount of water should not be too large, otherwise adverse root normal physiological activities. From March until September, a week topdressing a thin liquid fertilizer for plants, can effectively contribute to the growth of leaves. Su Tiexi adequate light environment. Try to keep the environment ventilated, otherwise the plants prone to scale insects. Su Tiexi warm and avoid cold, optimum growth temperature of 20 to 30 ℃ and and wintering temperature should not be less than 5 ° C.
The cycads breeding mainly propagated by seed and tillers breeding. Difficult to get seeds, tillers breeding has become the main breeding cycad seeds. Seed propagation Seed collected in late fall, the broadcast with also can sand Tibet, on demand at the next spring; kinds of thick-skinned and hard, raw sprouts slowly, usually 4-6 months after germination; temperature above 15 degrees to ensure the casing to be more deeply, about 3 cm, in the 30-33 ° C, high temperature, about 2 weeks to germinate; slower growing seedlings, seedlings 2-4 years before transplanting. Tillering breeding 1. The tiller time.: You can stop the growth of winter. Also in early spring - February to early summer. 2. Take the tiller buds: cycads often stem base and cadres tiller buds sprouted, fulfilling more than 3 years or 4 cycad base tiller morphology should be _select_ed to five leaves do the breeding material. Containing nutrients such tiller buds lignification adaptable, easy rooting survived. Avoid election over tender tiller buds, or perishable. Take the bud: the tiller buds with the mother plant connected to the foundation at cutting down with a sharp knife. Cutting to minimize injury stem bark. Incision slightly dry, coarse sand content of humus soil is planted in the pot, put in the conservation of the semi-shade, the temperature is maintained at 27-30 ℃, easy to survive, has taken root, can directly Zairu the humus-rich, good drainage, breathable and strong culture of soil management; not taken root, should be placed in a cool, well-ventilated place to dry for 2-3 days, treatment of root-and then wait until the incision is slightly dry. Stems cut into 15-20 cm of the pieces can also be buried in the sandy loam it around sprout, further sub-plant cultivation. 3. Of root: planted in a prime sand depth the tiller buds height of 1/2. To prevent wound rot before planting should be coated on the wound ash, charcoal powder, sulfur powder. After planting, watering, and then on the interior to see the light at the conservation. About 2 months sprouted new roots, pumping 3-4 1-2 students new leaves.

The cycad fruit package this fruit leaves the Cycas revoluta the aka Fissidens banana, the fire refuges banana, Jin Dynasty, cycads, folk, the name of the cycads with more, one that its wood density sink into the water that, heavy as iron named; another said to need a lot of iron, its growth and even decline dying cycads, with nails driven into its trunk, you can revive, repeat the vitality and therefore name of. , Cycads not just one kind, but a cluster groups, often called cycads, cycads, botanically, it is a seed plant doors, gymnosperms Amon, Su Tiegang, cycads mesh plant. Cycads is the world's most ancient gymnosperms and dinosaurs, the kings of the world at the same time, geologists as the "living fossil plants. It originated in the Paleozoic Permian flourished in Mesozoic Triassic (dating back 225 million years), Jurassic (dating back 190 million years) into the most peak, almost throughout the whole earth, to the Cretaceous (BP 136 million years) period, began to flourish angiosperms gradually decline. To Quaternary (250 million years ago) the advent of glaciers, the northern cold front southward invasion, cycads extinction in Sichuan, Yunnan and other places, but due to the Qinghai-Tibet Plateau, Qinling barrier, some cycads survived. Today, cycads save a total of about 10 genera and 110 species are mainly distributed in the tropical and subtropical regions of the northern and southern hemispheres, Wild 1 genera (Cycas) about 10 species distributed in Yunnan, Guangdong, Fujian, Taiwan, Guizhou, Hunan, Hainan and other places. Cycad trunk pith containing starch, edible, but also for the produced wine, can increase the alcohol yield; such as the peacock, highly ornamental, Xishuangbanna Some ethnic adopt its tender leaves feathery, stretching around leaves as a vegetable; seed size, such as pigeon eggs, slightly flat, round, golden yellow, shiny, ranging from dozens of tablets, many hundreds of tablets, the annular clustered at the top of the tree, very beautiful, it was called " Peacock Hatching Eggs, some farmers in Guizhou peeled with pig's feet stew to eat. As the saying goes, "Tieshukaihua, dumb speak" the Millennium the cycads bloom "or" Tieshukaihua horse Longhorn fruit leaf shape Myriophyllum, end multi spines, hairy surface. The metaphor thing long and difficult, even impossible. But in fact is not the case, especially in tropical regions, more than 20 years of cycad almost every year can open "flower". Cycads dioecious different flower-shaped, flowering from June to August, the male cones oblong, stand in the green pinnata, tawny bouquet containing proudly vitality spillover tiger angry, haughty and solemn; female cones flat round, pale yellow, close to the stem tip, as indifferent to the quiet of the Virgin, calm and submissive acceptance of tropical, subtropical sunlight. In fact, cycads are gymnosperms, only roots, stems, leaves and seeds, did not spend the reproductive organs, so, Tieshu flowers, seeds. Three huge cycads, one male and two female, Yunnan Botanical Garden introduction comes from the wild in the late 80s of the last century, the oldest ever discovered in Yunnan Province, cycads, tree age, almost a thousand years, the majority of Chinese and foreign visitors as "cycads King ", called the rare treasure. Their school called labyrinth cycads Cycas.pectinata Griff, this plant is endangered by the state as a secondary protection of plants.
