Lishu sorghum

Sorghum, Gramineae, Sorghum. Annual herb. The stalk is solid and has pith in the center. Tillering or branching. The leaves are like corn, thick and narrow, covered with wax powder, smooth, and the midvein is white. Panicle, spike shape has two types: belt and hammer. Caryophylls are brown, orange, white or yellowish. The seeds are ovoid, slightly flat, sticky or non-sticky. Sexual preference for warmth, drought resistance and waterlogging tolerance. According to the characters and uses, it can be divided into edible sorghum, sugar sorghum, broom sorghum and so on. China is widely cultivated, especially in the northeast. Grain for food, wine (sorghum) or maltose. The stalks of sugar sorghum can be made into syrup or raw food; The brooms can be made of brooms or cooking brooms with sorghum ears; Young leaves are dried in the shade for silage, or can be used as feed after drying; Caryophylls can be used as medicine, can eliminate dampness and phlegm, and calm the heart and soothe the nerves. At present, the origin of sorghum has not been determined, but many researchers believe that sorghum originated in Africa and was later introduced to India and then to the Far East. Sorghum is widely distributed and has many morphological variations. Africa has the most varieties of sorghum. Snowdon (1935) collected 17 wild sorghum species, 16 of which came from Africa. Among the 31 cultivated species he identified, Africa accounted for 28 species; Of the 158 varieties, only 4 are found outside Africa. China sorghum (S.bicolor var.kaoliang) is also known as maize, millet, reed millet, millet, etc. There have been two theories about its origin and evolution for many years: one is that it was introduced from Africa (or India). Second, it is native to China. Because sorghum has been cultivated and trained in China for a long time, it has gradually formed a unique China sorghum group, and many botanical forms and agronomic characters are obviously different from all kinds of sorghum originated in Africa. China sorghum has white veins, small glume coating, easy threshing, good rice quality, few tillers, developed aerial roots, dry pith after the stem matures, and little or no sugar content. In addition, when China sorghum crosses African sorghum, F1 is easy to produce strong heterosis. It shows that the genetic distance between the two sorghum species is quite different. Sorghum is one of the earliest cultivated cereal crops in China. The unearthed cultural relics and agricultural books about sorghum have a history of at least 5000 years. For example, "Compendium of Materia Medica" records: "Corn was planted in the north to prepare for food shortage, and the rest was used for cattle and horses, which has been cultivated for 4,900 years."
