Perennial shallow-water herbs with creeping rhizomes. The culm is erect and1-2m high. Ligule membranous, about 65438 0.5 cm long, with sharp tip; The leaves are flat and broad, 50-90cm long and15-30mm wide. Panicles are 30-50 cm long, most of which are clustered and developed in fruit. The caryopsis is cylindrical, about 12 mm long, and the embryo is small, which is 1/8 of the fruit.
Native to China and Southeast Asia, it is a common aquatic vegetable. It is distributed in temperate Asia, Japan, Russia and Europe. Whole grass is an excellent feed and a wintering place for fish. It is also a pioneer factory for dam reinforcement and land reclamation.

growing environment
Zizania latifolia is a thermophilic plant, and its optimum growth temperature is 10-25℃, and it is not cold-resistant, cold-resistant, heat-resistant and drought-resistant. There are many double-season plants in the plain area. Double-season plants have low requirements for the length of sunshine, but high requirements for water and fertilizer conditions. Temperature is an important factor affecting pregnancy.
Zizania latifolia has a well-developed root system and needs a lot of water. It is suitable for clay loam or loam with sufficient water, convenient irrigation, deep and soft soil layer, fertile soil, rich organic matter and strong water and fertilizer conservation ability. ?
