The morphological characteristics are evergreen trees of the genus Cinnamomum of Lauraceae, which are 12-17 meters high. The bark is grayish brown and fragrant, with young branches slightly quadrangular. Leaves alternate, leathery; long elliptic to sublanceolate, 8-17 cm long and 3.5-6 cm wide, apex acute, base obtuse, entire, upper green, glossy, gray-green below, pilose; with free 3 veins, conspicuously raised below, veinlets transversely parallel; petiole stout, 1 × 2 cm long. Panicle axillary or subterminal, 10-19 cm long, pubescent; flowers small, ca. 3 cm in diam.; pedicel ca. 5 mm; perianth tube ca. 2 mm, lobes 6, yellowish green, elliptic, ca. 3 mm, densely pubescent inside and outside Stamens developed in 3 whorls, anther moment round chamber, 4-loculed, valved, outer 2 whorls of filaments without glands, anthers introverted, 3rd whorls of stamens extroverted, filament base with 2 glands, innermost whorl staminodes, anthers heart-shaped; pistils slightly shorter than stamens, ovary elliptic, 1-loculed, ovules 1, style thin, as long as ovary, stigma slightly discoid. Paddle fruit elliptic or Obovate, apex slightly truncate, dark purple, ca. 12 × 13 mm, with persistent perianth outside. Seeds long ovate, purple.

First, the growth habits of cinnamon like a warm and humid environment, young trees like shade, and adults like plenty of sunshine. For soil requirements: the sandy soil with deep soil layer, loose and fertile soil and rich in organic matter is better.

Second, select fields with high terrain and good drainage for soil preparation and fertilization, and cultivate them carefully. Combined with soil preparation, apply sufficient basic fertilizer: 3000 kg of soil miscellaneous fertilizer, 20 kg of urea and 50 kg of phosphorus and potassium fertilizer per mu. Then make a high bed and wait for sowing.

Third, sow cinnamon and propagate with seeds. It is divided into two steps: seedling raising and transplanting. The sowing time is spring sowing. Before sowing the seedlings, soak the seeds in clean water for 48 hours, then sow them on the whole border surface according to the row spacing of 30 cm, and water to preserve the moisture to facilitate the emergence of seedlings. The seedlings can emerge in about 30 days. After the seedlings were collected, the field management should be strengthened and the seedlings could be transplanted after one year of cultivation. The sowing rate is 20 kilograms per mu. The cinnamon seedlings cultivated by transplanting were planted on the whole border surface according to the row spacing of 4 x 2 meters. Watering to preserve soil moisture, in order to survive.

Fourth, field management of cinnamon seedlings or transplanting after survival should pay attention to ploughing and weeding. Watering immediately in dry weather and timely drainage in cloudy and rainy weather. Topdressing once a year in spring: 2000 kg of topdressing soil fertilizer, 15 kg of urea and 30 kg of phosphorus and potassium fertilizer per mu. The seedlings grew slowly in the first few years of transplanting, but some short-term crops should be planted occasionally to increase income.

5. Control of diseases and insect pests the main diseases of cinnamon are brown spot, which can be controlled with 1 ∶ 1 ∶ Bordeaux solution at the initial stage. Root rot disease, in the initial stage of the disease with 50% bacilli spray control. The main pests are longicorn beetles which can be dipped in cotton to control dichlorvos. The leaf curl moth is sprayed with permethrin.

Harvest and process cinnamon in autumn after 15 years of growth, the bark will be peeled off and dried in the sun and can be sold as medicine. The thin treetops that cannot be peeled are cut into small segments 40 centimeters long and dried in the sun are cinnamon branches. Before and after Frosts Descent, the immature fruit was collected and dried in the sun. After distillation of leaves, twigs, fruits and broken cinnamon, cinnamon oil can be obtained.
