The reed is a very good weaving material. The reed plant is tall and the underground has a well-developed rhizome. Stems erect, stalks high 1 to 3 meters, often under the section of white powder. Leaf sheaths cylindrical, glabrous or with fine hairs. The ligule is hairy, long-lined or long-lanceolate, arranged in two rows. The leaves are 15-45 cm long and 1-3.5 cm wide. Panicle branches dense, extending obliquely, inflorescence length 10-40cm, spikelets 4-7 flowerlets; Ying 3 veins, a short Ying, Er Ying slightly longer; the first floret is mostly male, more than two sex; The tip of the external sample is long and acuminate, the long filamentous pilose of the base plate is 6-12mm long, the internal file is about 4mm long, and the ridge is rough. With long, thick rhizomes, mainly rhizomes.
Born in low wetlands or shallow waters, reeds are often seen as waterside plants. The reeds are often confused with Hanmang. The difference is that the stems of the reeds are hollow and Hanmang is not. In addition, Hanmang is everywhere, and the reeds are optional. Water is born.
Flowering in summer and autumn, panicles, terminal, evacuable, 10 to 40 cm long, slightly pendulous, spikelets containing 4 to 7 flowers, monoecious, inflorescences ca. 15–25 cm, spikelets 1.4 cm long, white-green Or brown, the spikelet at the bottom of the inflorescence is male, the rest are both male and female, flowering from August to December. The fruit of the reed is caryopsis, lanceolate, with persistent style at the top.
Reeds grow in ponds, banks, rivers and rivers, and often form a pond. In our country is widespread, where the Liaohe River Delta to the northeast, Plain, Sanjiang Plain, Hulun Buir and Xilin Gol Grassland in Inner Mongolia, Xinjiang, Bosten Lake, Tacheng and Ili River Valley Emin Valley, Baiyangdian reed area such as the North China Plain, is big Area where reeds are concentrated.
Born in shallow water or low-humidity, new wheat, wheat, or other paddy fields or dry fields are vulnerable. Reeds have rhizomes that run transversely. In natural habitats, rhizomes predominate, rhizomes criss-cross and form a network, and even thicker rhizomes form on the surface of the water. walk. Rhizomes have a strong vitality and can be buried underground for a long time. Rhizomes 1 meter or even more than 1 meter can develop into new branches once conditions are suitable. It can also be bred with seeds, and seeds can spread with the wind. The range of adaptation to moisture is very wide. From the soil wetting to long-term accumulation of water, from the depth of several centimeters to more than 1 meter, can form reed communities. In rivers and lakes with a depth of 20 to 50 centimeters, the slow flow of rivers and lakes can form a tall barnyard grass community known as the "grasswood forest." In the Baiyangdian area of ​​the North China Plain, the germination period is early April, the leaf stage is early May, the growth period is from early April to late July, the booting period is from late July to early August, the heading period is from early August to late, and the flowering period is late August. In early September, the mature period of seeds is in early October and the deciduous period is after the end of October. In the middle and late March, the Shanghai area grew buds from underground rhizomes, which took place from April to May and bloomed from September to October. In May to June in Heilongjiang, the seedlings were only vegetatively grown. The wintering shoots were formed from July to September. The wintering shoots germinated from May to June, and from July to August, they matured from August to September.
