Classification theme: Lauraceae
Morphological characteristics: trees; The bark is grayish brown, and the young branches have four edges and are brown fine hairs. Leaves alternate or nearly opposite, leathery, oblong to nearly lanceolate, green at the top, hairless, midvein and lateral vein obviously depressed, sparse below, and three veins at the base. Panicle axillary or terminal, with small white flowers; Tepals 6. The fruit is oval and dark purple.
Planting technology: 1, land selection and soil preparation: Cinnamomum cassia is a deep-rooted tree species, and yellow loam with deep soil layer, loose texture and good drainage is the best, which is not suitable for breeding and seedling raising in soil with high groundwater level and large sand content. All land preparation should be ploughed and dried. After the topsoil is sun-dried, the ridge width is 1.2m, and the ditch width is 40cm. Clods should be broken and raked. 2. Seed treatment: In February and March, when the pericarp of cinnamon seeds is purple-black, it can be harvested in batches. The recovered fresh fruit should be washed in the pool to remove the peel and pulp, and then picked up to dry the surface moisture before sowing. Seeds should not be exposed to the sun and placed for too long. If you buy it in the market, you need to pick fresh and full fruits, wash them immediately after you buy them, and put them in the ground to dry. 3. Sowing method: One acre of land can sow about 50 kilograms, and the spacing between plants is about 6 cm. After sowing, the surface is covered with a thin layer of soil, and after watering, it is directly covered with Leymus chinensis. 4. Seedling management: After 20 days of sowing, the seedlings will grow 6-7 cm in height, ferns can be removed, and a shade shed with a height of about 1.2 m can be built. After 30 days, when the leaflets of seedlings are as big as fingers, potassium dihydrogen phosphate foliar fertilizer can be sprayed. Spraying once every 15 days. It can also be sprayed with pesticides and fungicides. After 80 days, when the seedlings grow 5-6 leaflets, 50 kilograms of compound fertilizer can be applied per mu. From winter to the future, when the seedlings grow to 30-35 cm high, the shed can be uncovered, and the seedlings can be dried by controlling water and fertilizer, so that the Yuzryha bamboo shoots can be dried to mature wax, so as to ensure a high survival rate when transplanted in February-March of the following year. 5. Planting site selection: At this time, mature seedlings should be planted on hillsides, because hillsides are mostly yellow loam with loose and deep soil, which is conducive to the growth of deep-rooted plants. It can be planted in mountainous areas where crops such as Morinda officinalis and cassava have been harvested, and it can also be planted on terraced fields of returning farmland to forests. The plant spacing should be between 80- 100 cm, and the plants should be watered. Weeding and fertilizing once a quarter. Apply nitrogen and phosphorus fertilizer to promote growth in the first three years, and apply potassium fertilizer in the fourth year. In the fifth year, when the height of the tree has reached 3-4 meters and the diameter is about 10 cm, the first harvest can be carried out. After harvesting, new buds will grow on the roots, leaving 2-3 strong plants and cutting off the rest. In winter, in addition to weeds, it is necessary to prune drooping lateral branches and branches of pests and diseases to make the trunk straight and strong to ensure a bumper harvest next year. 6. Pest control: Disease control is the main stage of Cinnamomum cassia seedlings, and pesticides and fungicides can be mixed and sprayed every time foliar fertilizer is sprayed. If brown spot, anthracnose and powdery mildew appear after transplanting, it can be sprayed 600 times or 3000 times. If there are borers, leaf rollers, silkworms, etc. , can kill 2000 times or spray malathion 1500 times. If longicorn beetles burrow into the trunk or branches, 80% dichlorvos stock solution can be soaked in cotton wool and stuffed into the wormhole, and then sealed with mud. From February, 65438 to March of the following year, cinnamon, cassia twig and laurel leaf were harvested in winter and spring, and the cut branches and fallen leaves of diseases and insect pests were cleared out, and centralized burning was used for garden cleaning.
Medicinal value: sweating, relaxing muscles and tendons, warming channels, helping yang to disperse qi, calming qi, reinforcing fire to help yang, inducing fire to return to the source, dispelling cold and relieving pain, promoting blood circulation and dredging collaterals.
