Wild rice is not a bamboo shoot.

Wild water bamboo shoots, also known as tall gourd, mizuna bamboo shoots, mizuna hand, water bamboo shoots, tall bamboo shoots. It is a perennial rooted herbaceous plant of the genus Zizania of the grass family. Divided into double-season water bamboo and single-season water bamboo (or divided into a cooked water bamboo and two cooked water bamboo), double-season water bamboo (two-cooked water bamboo) yield is higher, the quality is also good. Ancient people called wild rice "Zizania". Its appearance is similar to bamboo shoots, but not bamboo shoots, but a kind of aquatic vegetables, the essence of the variegated flower stalks of Zizania, due to the parasitism and stimulation of the Black Spike fungus, the apex of the cells of the several sections of the rapid proliferation, expansion and the formation of.

Before the Tang Dynasty, wild rice was cultivated as a food crop, and its seeds were called mizuna rice or carving Hu, one of the six grains (sticky rice, millet, grain, sorghum, wheat, mizuna). Later, it was discovered that some mizutaki did not twig due to infection with black powder fungus, and the plants were free of disease, and the stems continued to expand, gradually forming spindle-shaped fleshy stems, which is now edible wild rice. It grows along the Yangtze River and the lake, and is suitable for growing in fresh water.

Morphological characteristics of wild rice

1, roots: roots for the fibrous roots, ring born in the tiller section as well as stolon nodes, 20-70cm long, 2-3mm thick more.

2, stems: stems are divided into underground stems and above-ground stems. Aboveground stems are short shrunken, partially buried in the soil, with multiple nodes, can produce multiple tillers, forming tiller clusters. After the main stem and tillers enter the reproductive growth, the shortened nodes elongate, the front end of the several sections of deformed expansion, the formation of fat fleshy stems, 25-35cm long, the transverse diameter of about 3-5cm, the cross-section of the elliptic or sub-circular.

3, leaves: composed of leaf blade and leaf sheath. Leaf blade is long lanceolate, wide flat and flat wide, smooth back, rough surface, about 100-160cm long, about 3-4cm wide, grass green. Leaf sheaths are 25-45cm long, clasping each other to form a pseudostem. Leaf blades and leaf sheaths are connected with triangular leaf pillows, called "wild rice eyes". The ligule is membranous and slightly triangular.

4, flowers and seeds: panicle, 30-50cm long, branches mostly clustered, ascending, fruiting. Male spikelets 10-15mm long, compressed on both sides, inserted in the lower part of the inflorescence or in the upper part of the branches, purplish, lemma 5-veined, apical acuminate with a small cusp, palea 3-veined, midvein ridged and hairy, stamens 6, anthers 5-10mm long.
