Subspecies classification
1, Setaria viridis: The main difference from the original subspecies is that the plant is stout and tall, and several nodes at the base have adventitious roots. The leaf sheath is loose, the upper part is sessile and hairless, and there are dense and slender cilia at the edge; Ligule is a ring of dense long cilia; Leaf blade linear, both surfaces glabrous. Its inflorescence is large and spikelets are dense. The base of the inflorescence extends with the branchlets clustered with spikelets, which are slightly sparse, but the spikelets of the bundle are not connected with the glume.
2. Setaria crassa: The stems are prostrate, short and thin, and most knees at the base are inclined or upright. The leaf sheath is loose, the basal leaf sheath is covered with dense wart hairs, and the edge has long cilia; The ligule is a circle of cilia; Leaf blade linear, subulate or narrowly lanceolate, glabrous and rough. Panicle ovate or elliptic.
Law:
Seed propagation: The suitable temperature for seed germination is 15~30℃. The appropriate depth of seed collection is 2~5cm, and the ungerminated seeds in deep soil can survive for more than 10 years, and the flowering and fruiting period is from June to September. A plant can bear thousands to tens of thousands of seeds. Seeds are spread by wind, irrigation and harvesting. Seeds germinate after hibernation. Strong adaptability, drought tolerance and barren tolerance, acid or alkaline soil can grow. Born in farmland, roadside and wasteland.
