The main differences are subject classification, morphological characteristics and living habits, as follows:

First, the disciplines are classified differently.

1, rhubarb rice

Big yellow rice, alias soft yellow rice, millet. It belongs to Gramineae, Panicum and Panicum.

2, small yellow rice

Millet is also called millet, millet, yellow rice and millet in the north. It belongs to Cyperaceae, Gramineae, Setaria and Sorghum.

Second, the morphological characteristics are different.

1, rhubarb rice

The culm is erect, solitary or a few tufted, 60 ~ 120 cm high, jointed and densely bearded at the nodes. Leaf sheaths are loose and covered with verrucous hairs. Panicle, spreading or dense, drooping when mature, with angular branches, rough bristles on the edge, bare lower part, dense branchlets and spikelets on the upper part; Spikelets ovate-elliptic, glume papery. Clove is round or oval, smooth and shiny, about 3 mm long, milky white, yellow or red. The seeds are white, yellow or brown and sticky.

2, small yellow rice

Once a year. Thick fibrous roots. The culms are stout and erect, with a height of 0. 1- 1 m or higher. Leaf sheaths are loosely wound around the stem, with dense verrucous hairs or hairless. The hair is close to the back where the edge meets the leaves, and the edge has dense cilia. The ligule is a circle of cilia; Leaf blade is long lanceolate or linear lanceolate, with sharp apex, blunt base, rough upper surface and slightly smooth lower surface. Panicle cylindrical or sub-rotating, usually pendulous, with discontinuous base, densely pilose spindle-shaped, bristles significantly longer than or slightly longer than spikelets, yellow, brown or purple; Spikelets are oval or nearly spherical, yellow, orange or purple.

Third, different living habits.

1, rhubarb rice

Dahuang rice is suitable for poor and dry soil. In China, millet planting is generally bounded by Shanxi and Shaanxi Province (about 1 10 degrees east longitude), with waxy millet in North China and the east of Northeast China and japonica millet in the west of Shaanxi, Gansu and Ningxia.

2, small yellow rice

The growth period of millet is only between 80d- 130d, which has the advantages of drought resistance, barren resistance and storage resistance, and is suitable for growing in arid areas lacking irrigation.
