Zizania latifolia, known as Manchurian wild rice, is the only member of the wild rice genus Zizania native to Asia. It is used as a food plant, with both the stem and grain being edible. Gathered from the wild, Zizania latifolia was once an important grain in ancient China.
Zizania Latifolia, native to China and Southeast Asia, is a relatively common aquatic vegetable. Zizania latifolia is found in temperate Asia, Japan, Russia and Europe. The whole grass is an excellent feed and a wintering place for fish. It is also the pioneer plant in levee building.
Zizania latifolia is perennial, with prostate rhizome.It has thick fibrous roots. Culms are tall erect, 1-2 m tall, ca. 1 cm in diameter, with many nodes, adventitious roots on basal nodes.
Zizania Latifolia leaf sheath is longer than its internodes, hypertrophic, with small transverse veins; The leaf tongue is membranous, ca. 1.4 cm long, apical. The leaf blade is flat and broad, 50-90 cm long, 15-30 mm wide.
Panicles are 30-50 cm long, branches many clustered, ascending, fruiting spreading; The male spikelet 10-15 mm, compressed on both sides, above lower part of inflorescences or branches, purplish, lemma 5-veined, apical acuminate with small cusp, lemma 3-veined, midrib, hairy, stamen 6, anther 5-10 mm; The female spikelet is cylindric, 18 -- 25 mm long, 1.5 -- 2 mm wide, attached to upper part of inflorescence and lower part of branches and main shaft, lemma 5-veined, awn 20-30 mm long, lemma 3-veined. Caryopses are cylindrical, ca. 12 mm long, embryonically small, 1/8 of the fruit body.
Zizania latifolia is a temperature-loving plant, growing at 10-25℃, intolerant of cold and high temperature and drought. Plain area planted wild double season, double season wild for the length of sunshine requirements are not strict, high requirements for water and fertilizer conditions, and temperature is an important factor affecting pregnancy Zizania Latifolia.
Zizania latifolia has a developed root system and needs more water, which is suitable for sufficient water source, convenient irrigation, deep and soft soil layer, fertile soil, rich in organic matter, and clay or loam with strong ability of water and fertilizer preservation.
Zizania Latifolia is produced in Heilongjiang, Jilin, Liaoning, Inner Mongolia, Hebei, Gansu, Shaanxi, Sichuan, Hubei, Hunan, Jiangxi, Fujian, Guangdong and Taiwan, temperate Asia, Japan, Russia and Europe.
Zizania latifolia have quarterly from the autumn and summer-autumn season, points strains breeding, the Yangtze river basin quarterly zizania latifolia in the tomb-sweeping day to Zizania Latifolia mound engraftment. Before autumn Zizania latifolia harvest, select the excellent single plant of pregnant Zizania latifolia, thick and tender meat of Zizania latifolia, main Zizania latifolia and tiller Zizania latifolia with the same harvest period, free of wild rice, no diseases and insect pests, and no male Zizania latifolia around, and stick as a symbol. Gray Zizania latifolia and male Zizania Latifolia should be found to knot the leaves as a mark, and when dividing the stumps in the spring of the second year, gray Zizania latifolia and male Zizania latifolia should be dug with roots. Plant 200-300 tons per acre of land. After selecting good seed plants to be harvested, the bushes of Zizania Latifolia will be dug with roots from mid-December to mid-January of the following year.
Zizania latifolia plant takes buds germinated from 1 to 2 underground stems below the surface as effective tillers, so the most upper and the most lower nodes of the plant should be removed, and a middle section should be left for cottage pseudo planting. The rows of the fake plants shall be 50 cm apart and 15 cm apart, with 80 cm walkways set aside every 5-6 lines. The depth of the fake plants shall be the same as the mud of Zizania Latifolia mound, and the shallow water layer of 1-2 cm shall be maintained. In order to promote the early root germination and prevent freezing, mulch can be used to cover the rice fields, so as to enable Zizania Latifolia to grow and develop in advance, so as to mature early and increase the yield.
When the false seedlings survive, each acre of rice field can be applied with ammonium bicarbonate 3-4 kg, promoting the growth of seedlings. In spring to rhizophyte dense, crowded Zizania Latifolia. When the seedling height is 10 cm or so, we should remove the weak tiller, at the same time to the root edge pressure 1 mud, so that tiller buds spread around, in order to improve the nutritional status and plant ventilation and light. In order to reduce the occurrence of male Zizania Latifolia, seedlings with over-vigorous growth tendency should be removed 1 week before transplanting and transplanting.
Zizania latifolia is of great economic value, stalk base for the fungus parasitic, thick and tender, similar to bamboo shoot, called Zizania Latifolia bamboo shoot (high bamboo shoot, bamboo shoot, wild melon), is a delicious vegetable. Caryopsis Zizania latifolia rice, for food, nutrition and health value. The whole grass is an excellent feed and a wintering place for fish It is also the pioneer plant in levee building. Ancient Zizania Latifoliau growth is normal, autumn bear fruit, called carved hu rice, for one of the six grains. Because of black ear fungus sends formation of deformity, it can not blossom and bear fruit, becoming a vegetable to use.
Zizania Latifolia is rich in nutrition, which not only contains sugar, organic nitrogen, water, fat, protein, fiber and ash powder, but also contains 17 amino acids such as lysine, among which threonine, methionine, phenylalanine and lysine are essential amino acids for human body.
Zizania Latifolia is sweet, slightly cold. Zizania Latifolia can remove heat, produce saliva, quench thirst, diuretic, dehumidify, Tonli. Zizania latifolia cures chronic heat and wet abdominal pain, chronic thirst, chronic diarrhea, alcoholism, lack of milk, etc.
