Changzhi (长治) is a hemp growing area of south-eastern Shanxi (晋东南, Jìn dōngnán), China, drawn on the city of Changzhi with the counties of Yushe and Zuoquan, in Jinzhong. Its hemp is called Lu hemp (潞麻, Lù má). The Lu hemp of Changzhi, like the hemps of Laiwu in Shandong and Yuzhou in Hebei, was among the Chinese hemps known for their quality on the international market,[1] and it is one of China's noted local varieties.[2] Seed of four hemp landraces was collected in 2020 at Qinyuan, Lucheng, Pingshun and Xiangyuan, in Changzhi.[3]: Table S1
Hemp in the Qing gazetteer
The provincial gazetteer of Shanxi compiled under the Yongzheng emperor, whose preface is dated 1734, counts four kinds of 麻 among the products of the province. The first is 大麻 (dàmá), whose seed is greyish green and round and is pressed for oil. Quoting Li Shizhen, the entry calls it 火麻 (huǒmá), grown everywhere for its fibre and seed, with male and female plants; its bark makes cloth, shoes and rope, and its white, light, hollow stalks serve as candle wicks. The entry adds that the departments of Liao and Qin abound in it (遼沁等地饒焉).[4] Under Liaozhou itself the gazetteer notes that all three of its counties produce hemp, pressing the seed for oil and retting the bark for rope, and that farmers always count it among the grains.[4]
Farming
In the Lu hemp district of south-eastern Shanxi, grain, hemp and oil crops are mostly intercropped and relay-cropped, in a rotation of five harvests in three years.[5]
Landraces
Jun Li and colleagues collected the achenes of twenty hemp landraces in nine provinces of China in 2020 for a study of their chemistry, and stored the seed in the National Gene Bank of Traditional Chinese Medicine, at the Institute of Chinese Materia Medica.[3] Four of the twenty come from this area: CZ36 from Qinyuan, CZ37 from Lucheng and CZ40 from Pingshun, all in Changzhi, and CZ44 from Xiangyuan, which the table places in "Changshui". All four have small, dark achenes, weighing between 19.4 and 27.0 g per thousand.[3]: Table S1
