How to grow cinnamon

Cinnamomum osmanthus is a spice plant that grows in the subtropics. It is also called cinnamon. It has the functions of dispelling cold, relieving pain, activating blood circulation and removing blood stasis. So what are the methods for growing cinnamon cassia? Here is what I do I hope the cinnamon planting methods you compiled will be useful to you.

Cinnamon planting method

1. Planting environment requirements

Cinnamon prefers tropical and subtropical areas with warm and humid climate and even rainfall distribution. The annual average temperature is required to be above 18°C, and the annual average rainfall is above 1,200 mm. Cinnamon is a semi-shade plant, and young trees like shade. They require 60% to 70% shade and avoid direct sunlight. As the tree grows older, it gradually becomes more tolerant of sunlight. Adult plants like sufficient sunlight. Sunlight can improve the fruit setting rate and Promote sufficient cinnamon oil content and good medicinal quality. Cinnamon is a deep-rooted plant that prefers red sandy loam with a deep soil layer, good drainage, strong permeability, and acidic reaction (pH 4.5 to 5.5). It can be grown in Xishuangbanna, Dehong, Hekou, Funing, Yuanyang and other places in our province.

2. Planting methods

(1) Land selection and preparation

The nursery site should be well shaded, with convenient water sources, loose, fertile soil and good drainage. On the slopes under the forest to the southeast, the soil is preferably acidic red or yellow soil. After selecting the site, plow the soil in winter. One month before sowing, apply decomposed organic fertilizer, rake it flat and make a border with a border width of 1.2 meters and a height of 20 cm. The border spacing is 33 cm and drainage ditches are opened around it. The planting site should be a gently sloping mountain forest hinterland with a slope of 15 to 30 degrees, with the wind facing the sun and a slope of 15 to 30 degrees. It is appropriate to select some of the original trees as shade trees before the seedlings are planted.

(2) Seedling cultivation

1. Seed propagation

(1) Seedbed Seed beds should be located on higher ground, with good drainage, and soil rich in organic matter. Understory clearings or slopes with good shade (light transmittance 30%). Choose a sunny day and plow when the field is relatively dry. Plow about 15 cm. When plowing, crush the soil and pick up stones and weeds. Make a smooth border. The border width is 120 cm, the ditch width is 30 cm, and the ditch depth is 25 cm. The ditch should be smooth to facilitate drainage.

(2) Seed selection and seed treatment generally use high-quality cinnamon such as Vietnamese cinnamon, white bud cinnamon or Ceylon cinnamon, 10 to 15 years old, with straight trunks, thick and oily skin, fragrant and sweet taste, and strong growth. The plant that is free from diseases and insect pests and grown from seedlings is the mother plant. Harvest the fruits when they are ripe and purple-red, and sow them as you pick them. Select large and plump seeds, remove the pulp, soak them in 0.3% formalin for half a minute, place them in a closed tank for 2 hours, wash off the liquid with clean water, and soak them in clean water for another 24 hours. Then mix the seeds and wet sand at a ratio of 1:4 to 1:3, and bury them in the pit with 2 to 3 cm of wet sand on the bottom. Then add the wet sand seeds, cover with straw, and keep them moist. , the seeds can be sown when bud spots appear.

(3) Sowing and raising seedlings are usually sown from March to April, sowing 10 to 16 kilograms per acre, digging trenches with a row spacing of 20 cm, sowing 40 to 50 seeds in each row, covering with 2 cm of soil, and covering with straw. And keep it moist frequently. During this period, pay attention to weeding, soil loosening and top dressing. Plant after 1 to 2 years.

(3) The best transplanting period is June to July at the beginning of the rainy season. Choose a cloudy day or light rainy day, and set the row-to-plant spacing (1.2 to 1.5 meters) (1 to 1.2 meters) (mainly for Guitong production and leaf harvesting) or the row-to-plant spacing (5 to 6 meters) on the prepared plot. (4 to 5 meters) (mainly for the production of cinnamon). Open holes, apply 10 to 20 kilograms of soil and fertilizer to each hole, mix well with the subsoil, cover the upper part with fine soil, and plant one seedling in each hole. Layer the soil and compact it. When the soil is halfway filled, gently pull up the seedlings to stretch the roots. Then cover the soil slightly above the ground. Water the roots thoroughly and cover with grass to moisturize. In order to improve the survival rate, when transplanting the seedlings, you can trim off the overly long leaves and side branches, as well as the overly long main lateral roots, and dip the roots in yellow mud before planting.

3. Field management

(1) Cultivating and weeding Within 3 years after planting, perform cultivating and weeding once every winter, late summer and early spring, and hoe away 1 meter of weeds around the plants , loosen the soil, and bury the weeds in the holes. When cultivating and weeding, be careful not to damage the bark at the base of the trunk to avoid tiller seedlings sprouting and affecting the growth of the trunk.

(2) Top dressing 1 to 2 times a year for the first 2 to 3 years, during cultivating and weeding in spring. Fertilizers can be compost, urea, superphosphate, human feces, etc. Open an annular ditch on the outer edge of the tree crown, apply fertilizer in the ditch, and then cover it with soil to restore it. If it is dry fertilizer, water it in time if there is no rain after application.

(3) Pruning: Pruning is carried out every winter and spring, mainly to cut off excess tillers and side branches close to the ground to make the stems straight and strong, and to improve ventilation and light transmission in the forest. situation. After harvesting fruits, diseased branches, weak branches, and overly dense side branches should be pruned. The branches cut from pruning can be used as cassia twigs for medicinal purposes.

(4) The miscellaneous trees retained in the sparse cinnamon forest should be thinned gradually or appropriately when the cinnamon grows into an adult tree to facilitate the growth of cinnamon. Key points for growing osmanthus

Climate and soil

It likes a warm, humid and sunny climate with good drainage, fertile sandy loam, gray calcium soil or acidic reaction (pH 4.5 -5.5) red sandy loam is suitable.

Soil preparation

After plowing and breaking up the soil, make a border of 1m wide and 15-20cm high. Drainage ditches should be opened all around.

Planting

Seed seedling transplantation is generally used. After the seeds are mature, they are harvested and planted, or mixed with wet sand to hide them, but not more than 20 days. If they expire, they will lose their germination ability. Use the drill method, with a row spacing of about 15cm and a trench depth of 3-4cm. Sow 1 seed every 3-4cm. After sowing, cover with soil, water, and cover with hay. When the seedlings are 10cm high, leave one seedling every 6cm. After three years, when the seedlings are about 1m high, choose a rainy day from February to March for planting, with a row and plant spacing of about 2 to 3m.

Field management

Germination will occur 20-40 days after sowing. At this time, weeds should be removed, a shade shed should be erected to prevent exposure to the scorching sun, and water should be paid frequently to keep the soil moist. , to prevent drought. When the seedlings are 16-20cm tall, remove the shade shed and pay attention to irrigation and fertilization. After afforestation, weeding, loosening, and fertilizing must be done three times a year.

Pest and disease control

Pests include the larvae of the longhorn beetle. After discovery, the affected parts can be cut off and burned, and hunted or fumigated with sulfur vapor.
