Rice: is the grass family, the genus rice annual aquatic herbaceous plants, the fruit that is rice, after removing the glumes, bran layer can be obtained after rice, rice grains, milky white, olive-shaped, China's southern rice-producing areas for the main, northern provinces are planted.

Grain: Gramineae, dogwood annual plants, hulled and peeled called millet, small grains, yellow, bulbous, hundreds to thousands of fruits per spike, seed is very small, diameter of about 0.1cm, belongs to the drought-resistant and stable crop, altitude of 1,000m or less are suitable for cultivation.

One, the difference between the family

1, rice is the grass family, rice annual aquatic herbs, is the genus of rice as a grain in the most important and longest one.

2, grain is the grass family, genus dogwood annual plants, the ancient name of millet, corn.

Two, fruiting difference

1, rice fruiting that is the rice grain, rice grain after removing the husk is called brown rice, brown rice can be obtained by milling the bran layer of rice. Rice grain is large, milky white, olive-shaped.

2, each spike of grain fruits hundreds to thousands of grains, seeds are very small, diameter of about 0.1cm, the spike is generally golden yellow after maturity, ovoid seeds, small grains more yellow. Hulled and peeled called millet, small, yellow, bulbous grains.

Three, appearance difference

1, rice stalks erect, 50-150cm high, varying with varieties. Leaf sheaths loose, glabrous; ligule lanceolate, both sides of the base extended to the edge of the leaf sheath, with two sickle-shaped embracing auricles; leaf blade linear-lanceolate, about 40cm long, about 1cm wide, rougher, glabrous.

2. Cereal stalks cylindrical, 60-150cm high; leaf sheaths loosely wrapped around the stalks, densely warty or glabrous, hairs dense near the margins and on the back at the junction with the leaf blades, the margins densely ciliate; ligule a ring of cilia; leaf blades long lanceolate or linear-lanceolate, 10-45cm long, 5-33mm wide, apex pointed, base obtuse-rounded, scabrous above, slightly smooth below.

Four, the difference between the growing environment

1, rice like high temperature, humidity, short sunshine, the soil requirements are not strict, southern China is the main rice-producing areas, northern provinces are planted.

2, cereals like high temperature, fertility temperature 22-30 ℃, belong to the drought-resistant stable crop, altitude 1000m below are suitable for cultivation, China is mainly distributed in Shandong, Hebei, Northeast, Northwest and other places.
