Seed Seedlings
Site Selection and Land Preparation
Cinnamon is a deep-rooted tree species. It should be planted on flat slopes or idle wasteland with good drainage near water sources, as the soil is deep. , loose texture, moist and fertile sandy loam is the best. The land preparation should be thoroughly plowed and sun-dried. After the topsoil is whitened, 1950kg/hm2 of calcium, magnesium and phosphorus fertilizer should be applied, and 33000kg/hm2 of decomposed pig pen manure should be used as base fertilizer. Break up the soil, rake it flat, and open drainage ditches around it in preparation for sowing.
Sowing
The sowing season is from mid-March to early May. Since cinnamon seeds are short-lived, it is best to sow them as soon as they are picked. Before sowing, wash the seeds with clean water to remove moldy and bursting seeds. Soak the seeds with 5‰ potassium permanganate solution for 15-20 minutes, then rinse the solution with clean water, take out the seeds and sow them immediately. The appropriate sowing rate in the seedbed is 225~240kg/hm2, sow on demand with a row spacing of 20~24cm and a plant spacing of 5~7cm. The soil should be 1~1.5cm thick, soaked with enough water and covered with grass.
Seedling management
20 days after sowing, when the seedlings grow 5~6cm high, remove the grass and build a shade shed about 1.2m high. The light transmittance is required to be 30 %~40% to facilitate the growth of seedlings. After 30 days, when the small leaves of the seedlings are as big as a finger, you can spray potassium dihydrogen phosphate foliar fertilizer. From now on, spray once every 15 days. It can also be sprayed in combination with insecticides and fungicides. After 80 days, when the seedlings have grown 5 to 6 small leaves, 600kg/hm2 of compound fertilizer can be applied. After the winter solstice, when the seedlings grow to a height of 30 to 40 cm, the scaffolding can be uncovered, and the water and fertilizer can be controlled to dry the seedlings until the leaf tips are mature and sallow to ensure a high survival rate when transplanted in February to March of the following year. Cinnamon grows slowly in the seedling stage. Pay attention to cultivating and weeding, keeping the seedbed moist, but preventing water accumulation.
Planting management
Land preparation and afforestation
For planting, choose low hilly land with loose soil, deep fertile soil, temperature and humidity, sufficient sunshine, less susceptible to cold, and good drainage. Or the hinterland of the mountain with less erosion should be used as afforestation land. The slope direction should be east or southeast. In autumn and winter, the mountain should be prepared for full reclamation. The size of the hole should be 40cm × 40cm × 40cm. After weathering for 1 to 2 months, plant in early to mid-March. First apply 10kg of base fertilizer into the pit, and then pad some topsoil. Plant the seedlings and straighten them to make the roots stretch. Fill the soil in stages and make it slightly firm. Water the root fixing water thoroughly and then Cultivate with loose soil, and cultivate the rhizome with soil slightly above the ground. In times of drought, straw can be used to cover the hole surface to maintain soil moisture.
Planting density
Planting density varies slightly according to different business objectives. Generally, 1m×1m or 0.7m×0.8m is used, and the density can reach 9000~10500 plants/hm2, or even The highest density is as high as 15,000 plants/hm2. If the management level is high, use 1m×1.2m or 1.2m×1.2m.
Replanting and intercropping
Check the seedlings once within 30 days after planting to fill the gaps. Replant with saplings of the same age according to the original planting density. When young forests are first planted, some high-stem crops such as pigeon pea and cassava should be interplanted; after the forest is established, shade-growing medicinal plants such as Pleurotus lucidum and Amomum villosum can be interplanted to improve the soil structure and increase income. After the forest canopy is closed, intercropping is stopped.
Woodland tending
Cultivating and weeding: In the young stage, cultivating and weeding are required 2 to 3 times a year until the forest canopy is closed. During the last cultivating in November every year, weeds in the ground will be eradicated and covered around the plants to reduce soil water evaporation. Be careful during cultivating operations, and do not damage the stem base of the plant by hoeing to avoid tillering, consuming nutrients and affecting the growth of the trunk.
Watering and fertilizing: Watering and fertilizing should be done regularly within 1 to 2 months after afforestation to ensure the survival of the seedlings. It will depend on the drought situation in the future. Fertilizer is applied 2 to 3 times a year, combined with tending. In the first three years, nitrogen and phosphorus fertilizers are applied to promote growth, and potassium fertilizer is added in the fourth year. Apply 50g of nitrogen fertilizer, 50g of phosphate fertilizer or 100g of compound fertilizer to each plant each time.
Pruning and shaping: In order to make the plant tall and straight, it is necessary to perform pruning to remove the side branches and excess sprouts near the ground. After picking fruits, diseased branches, weak branches, injured branches, and overly dense branches of mature trees should be pruned to ensure the permeability of the forest land. The first pruning can be done 3 to 4 years after planting, and then every other year. Pruning intensity, generally for trees less than 4 years old, the retained crown should account for 1/2 of the tree height; for trees between 5 and 10 years old, the retained crown should account for 1/3 of the tree height; for trees over 11 years old, the retained crown should account for 1/3 of the tree height. 1/4. Pruning should be done during the dormant period.
