What are the common types of fern
1, long feather fern: long feather fern for a special kind of species, the shape of the tall, broad fronds, with a very large number of long linear sessile pinnae, at right angles from the axis of the pinnae spreading, so that it is in the genus of a variety of appear extremely prominent. This species is slightly closer to the European fern and its Asian varieties, but the pinnules are up to 20 cm long, long linear, spreading at right angles, and the ultimate segments are also longer, linear-lanceolate, pointed at the tip, and more or less crenate on both margins.
2, food fern: food fern plants about 1 m high, rhizomes long and transverse walk, leaf distal, fronds oblong-triangular, apex acuminate, base broadly cuneate, tricyclic pinnate, alternate, stalked, slightly upward obliquely spreading, oblong-lanceolate, apex long acuminate, with a short caudal head, the base of the sub-flat truncate or heart-shaped, the base of a pair of non-shortening. Distributed in southwestern Guangxi, Hainan, the Central and Southern Peninsula, Malaysia, Indonesia and other places.
3, European fern: European fern plant can be up to 1 meter high, the leaves split into many petals, growing on the smooth black stems, the plant grows up after the stem becomes very hard, the shoots can be eaten. Produced throughout the country, but mainly produced in the Yangtze River Basin and north of the region, subtropical areas are also distributed, born in the sunny slopes of mountainous areas and the edge of the forest in sunny places, altitude 200 ~ 830 meters, but also widely distributed in other tropical and temperate regions of the world.
4, sickle feather fern: sickle feather fern plants up to 2 meters high, rhizomes walk horizontally. The leaves are dry and papery, dark green, glabrous above and sparsely grayish brown pilose along the main veins below. Leaf veins dense, oblique upwards, visible above, obvious below, rachis and pinnae smooth, pinnules nearly smooth, all with 1 deep longitudinal groove above, glabrous in the groove, straw-colored. The form is close to that of the European fern, specializing in eastern Guangxi (Hexian), born in sunny places on mountain slopes.
5, hairy axial fern: hairy axial fern plants up to more than 1 m high, rhizomes walk horizontally, the leaves are distant, grain culm color or brown grain culm color, the leaf blade broadly triangular or ovate-triangular. In the Yangtze River south of the provinces and regions have grown, produced in Taiwan, Jiangxi, Guangdong, Guangxi, Hunan, Hubei, Shaanxi, Gansu, Sichuan, Guizhou, Yunnan, Tibet, born in the sunny part of the mountain slopes or valleys sparse forests in the forest clearing, Sichuan Yibin area called ? The Yibin area of Sichuan is called the "rice fern".
6, Yunnan fern: Yunnan fern plant height of about 1 m, petiole stout, upper light straw color, glabrous. The leaf blade is ovate-triangular, quadruple pinnatifid. The basal pinnae are the largest, oblong-triangular, apex acuminate, base broadly cuneate, opposite, obliquely spreading, long-petiolate, about 28 cm from the upper pair. Pinnae ternate, one with ca. 20 pairs of smaller lamellae, opposite or subopposite, spreading or obliquely spreading. Specialized in W Yunnan (Yingjiang), 1450 m. Hainan.
Where does the fern grow
The fern likes to be born in shallow mountainous areas in the sunny plots, mostly distributed in the sparse mixed coniferous and broad forests, and its edible part is the unfolding of the young and tender leaf buds as well as the upper part of the more tender stem. The stems are stout and fat, and the petioles are quite erect, often as high as about 60 centimeters. In spring, when the young leaves are still curled and unfurled, people pick them for consumption. It is widely distributed in mainland China as well as Southeast Asia, and is popular on tables in these regions.
Where does the fern originate
1, Hebei: Chengde fern is a famous wild vegetable in Hebei Province, Chengde area has an area of more than 33,000 hectares, divided into Longhua, Fengning, Pingquan, Kuancheng and other places.
2, Liaoning: fern in the mountainous areas of Liaoning Province are distributed, especially in the eastern mountainous areas of the distribution of a wide range, the number of exports to Japan and other countries, the domestic market is also very popular.
3, Inner Mongolia: fiddleheads are distributed throughout Inner Mongolia, but the main producing areas in Chifeng City, Xing'anmeng and other places, the annual output of about 200 tons, the local picking period in June.
4, Jilin: fiddleheads in Jilin Province, mountainous areas are distributed, the production of more than one, every year around May began to market, mainly exported to South Korea, and domestic sales are also very good.
5, Heilongjiang: fern at an altitude of 200 to 800 meters in the alpine zone are distributed, more mixed with weeds, the soil in mid-May, late May to early June harvest.
6, Guizhou: fern distribution is very much, in fact, ferns in Guizhou has the widest distribution, the most varieties, which ferns in the local picking period for the middle of March to August.
7, Hunan: fern in Xiangyin, Miluo, Zhang Guying and other mountains have, spring time is the fern picking period, after June or so fern on the molding grow up can not eat.
8, Ningxia: fern in Guyuan and Gansu Yuzhong County and other places in the distribution of more, especially for the Zhangxian fern higher quality, Jingyuan County, Taihe Mountain, Hassan also have a large number of distribution.
