Cinnamomum is a plant of the eucalyptus family and is one of the southern medicines. Cinnamon also has various names such as Mugui or Bangui. According to the "Compendium of Materia Medica" records, the benefits of liver and lung after the system of cinnamon can cure chilly fever and cold illness. Cinnamon, cassia twig, and cinnamon can also be used as spices. Even cinnamon leaves can be used to extract laurel oil. In short, cinnamon is really a treasure! It is native to Vietnam and its major producing areas are located in Guangdong, Guangxi, Hainan and Fujian provinces. Among them, the cinnamon of Guangdong Xijiang (which is cultivated in the mountainous areas along the Xijiang River) is the most famous. The cinnamon and laurel oil produced are famous for the pharmaceutical and spice markets at home and abroad. First, cinnamon habits. Cinnamon was born in the subtropical region and enjoys a warm and humid climate. The growth environment requires an average annual temperature of 20°C or more, and cannot be lower than 2°C. Fear of frost, the fastest growing season in the rain around 18 °C. The mature laurel has strict requirements on the nature of the soil and can grow well in sandy soils, clays, and acidic soils. If it can be planted on a hillside with deep yellow loam, it is most suitable and grows best. Cinnamon seedlings are afraid of strong sunlight, and adult trees need sufficient sunlight. According to related data, the conditions for planting cinnamon are found in most regions of the province, such as climate and soil. Its cultivation has many advantages, such as less investment, quick results, high return rate, long-term benefits, easy-to-use and easy-to-manage. At present, only some of the cities and counties in Deqing, Yunan and Gaoyao are planted in our province. There are few other places, so there is great potential and room for development. It can be widely promoted. Second, the propagation method of cinnamon is mainly seed breeding. 1. Selection of land and site preparation: Cinnamon is a deep-rooted tree species. It is best to choose a yellow loam soil with deep soil, loose texture and good drainage. It is not appropriate to breed seedlings in a soil with high groundwater table and sandy soil. Land preparation should all be ploughed and dried. After the top soil is whitened, it is 1.2 meters wide and 40 cm wide. It will crush the soil and push it flat. 2, seed treatment: 2-3 months, when the cinnamon seed skin is purple and black can be harvested in batches. The recovered fresh fruit should be put in the sink to wash away the peel and flesh, and then pick up and dry the surface moisture to sow. Seeds should not be exposed to sunlight and long-term exposure. If you want to buy in the market, you need to pick fresh and full fruit, buy it and wash it immediately, and dry it. 3, sowing methods: an acre can be broadcast about 50 kilograms, can be broadcast or sowing, seed spacing of about 6 cm, after sowing with a thin layer of soil to cover the surface, directly covered with water fern after the fern. 4. Seedling management: After planting for 20 days, the seedlings grow 6-7 cm tall. The fern grass can be removed and a shade shelter of about 1.2 meters high can be built. After 30 days, when the leaflets of the sprouts are as large as the fingers, potassium dihydrogen phosphate fertilizer may be sprayed. Spray every 15 days thereafter. Can also be combined with pesticides, fungicides spray together. After 80 days, when seedlings grow 5-6 leaflets, 50 kg of compound fertilizer can be applied. After the winter solstice, when the seedlings grow to 30-35 centimeters in height, the scaffolding can be lifted to control the water and control the fertilizers to dry the seedlings, and the shoots can be dried until they are cooked to ensure that the transplants are highly viable when transplanted in February-February. rate. 5, planting selection: At this time is mature saplings, planting to choose hillside, because the hillside mostly yellow loam, and loose soil, deep, conducive to the growth of deep-rooted plants. It can be planted on mountainous land where crops like cassava and cassava are harvested, or it can be planted on terraces where farmland is converted back to forests. The distance between the plants is 80-100 cm. It is advisable to apply enough water to the plant. After each quarter, weeds and fertilization are applied once. The first three years focused on nitrogen and phosphorus fertilizers to promote growth and potassium fertilizer was added in the fourth year. The first five years when the height of the tree has reached 3-4 meters and the diameter is about 10 centimeters, it can be harvested for the first time. After the harvest, the roots will grow new shoots, leaving 2-3 stout strong, and the rest will be cut off. In winter, besides removing weeds, it is also necessary to trim the pendulous collaterals and branches of diseases and insects to make the trunk straight and robust, ensuring a bumper harvest in the coming year. 6. Prevention and control of diseases and pests: Cinnamon is mainly used for disease prevention during the seedling period. Each spraying of foliar fertilizer can be combined with pesticides and fungicides. If brown spot disease, anthrax, powdery mildew, etc. occur after transplantation, the spray can be sprayed 600 times or clear 3000 times. For example, pests, leaf insects, and silkworms can be killed or killed 2,000 times or 1500 times malathion. If Tianniu drills into the trunk or branches, it can be immersed in the boring hole with 80% ddvp solution and then sealed with mud. From December to March of the following year, cinnamon, cassia twigs and bay leaf are harvested in conjunction with winter and spring, and the removed pests and detached branches are cleared out of the canyon and burned to clear the garden.
