Cinnamon planting technology

I. Planting environment requirements Cinnamon prefers tropical and subtropical regions where the climate is warm and humid and the rainfall is evenly distributed. The annual average temperature is required to be above 18°C ​​and the average annual rainfall is 1200mm or more. Cinnamon is a semi-negative plant. The young tree is hid and shaded. It requires 60% to 70% shade and avoids direct sun exposure. As the tree age grows, it will gradually tolerate more sunlight, and the plants will enjoy sunny sunshine. The sunlight will increase the seed setting rate and Promote the cinnamon oil is sufficient, the quality of medicine is good. Cinnamon is a deep-rooted plant, with a good depth of soil, good drainage, strong permeability, and a sandy red loam with an acidic reaction (pH 4.5-5.5). Xishuangbanna, Dehong, Hekou, Funing, Yuanyang and other places in our province can be planted.
Second, planting methods (a) selection of soil preparation sites should be selected shade better, convenient water, loose soil, fertile, well-drained southeast forest downhill, the soil with acid red, yellow soil as well. After the land was selected, the soil was plowed in winter. One month before sowing, the composted organic fertilizer was applied, and after the last cropping, the lotus root had a width of 1.2 meters, a height of 20 centimeters, a raft spacing of 33 centimeters, and a good drainage ditch around. Planting land should use leeward sunny, gradient slope of 15 to 30 degrees in the hinterland of the forest, the appropriate selection of the remaining part of the original forest for planting seedlings before the forest shade trees.
(B) Nursery
1. Seed Propagation (1) Seedbed seedbeds should be selected for high topography and well-drained soils with open spaces or slopes rich in organic matter and good shade (light transmittance of 30%). Choose sunny days, when the plots are dry, plowing, plowing about 15 centimeters, when the plowing will crush the clods, and remove the stones and weeds. Flat work. The surface width is 120cm, the width of the groove is 30cm, and the depth of the groove is 25cm. The ditch should be unobstructed and conducive to drainage.
(2) Selection and seed treatment are generally selected from cinnamon, white bud cinnamon or Ceylon cinnamon, etc. They are good for cinnamon for 10 to 15 years, straight trunk, thick skin, oily, fragrant, sweet, strong, no pest, and seedlings. The grown plants are mother plants. Harvested when the fruit is ripe purple, with the harvest with the broadcast. The seeds were well-picked, and the pulp was removed and soaked in 0.3% formalin for half a minute. The mixture was placed in a closed tank for 2 hours. The liquid was washed off with fresh water and soaked again in fresh water for 24 hours. Then mix the seed with the wet sand at a ratio of 1:4 to 1:3, mix it, bury it in a pit, place a 2 to 3 cm thick wet sand on the bottom, add the wet sand seeds, cover the straw, and keep it moist. When the seed appears budding, it can be sown.
(3) Sowing seedlings are generally sown from March to April, sowing 10-16 kilograms per acre, dividing the gap by 20 centimeters, spreading 40 to 50 grains per line, covering soil 2 centimeters, covering rice straw, and keeping them moist. Pay attention to weeding, loose soil and top dressing during this period. 1 to 2 years after colonization.
(3) Transplanting and transplanting period is better during the early rainy season from June to July. Select cloudy or light rain weather, on the preparatory plots, plant spacing (1.2 to 1.5 meters) (1 to 1.2 meters) (production of Guitong and picking blades) or row spacing (5 to 6 meters) (4 ~ 5 meters) (production of cinnamon mainly) open hole, apply 10-20 kilograms of soil miscellaneous fertilizer per hole, mix well with the subsoil, cover part of fine soil, and plant 1 seedling per hole. Layer pressure, fill half, the seedlings gently pull up, so that the root strip stretch, and then cover the soil slightly higher than the ground, soaking the root water, cover grass moist. In order to increase the survival rate, the leaves and lateral branches of the seedlings that are too long, and the main lateral roots that are too long can be repaired when transplanting, and the roots of the seedlings are planted with yellow mud.
3. Field Management (I) In the three years after weeding and weeding, every winter, late summer and early spring, one cultivator weeding, one weeds around the plant, and loose soil, buried the weeds in the hole. When weeding and weeding, take care not to damage the bark at the base of the trunk, so as not to sprout the seedlings and affect the trunk growth.
(b) Dressing for the first 2 to 3 years, top dressing 1 to 2 times a year, when cultivating and weeding in the spring. Fertilizer can be compost, urea, superphosphate, human feces, etc. Open the ring groove at the outer edge of Qi Shuguan, fertilize it in the ditch, and then cover the soil to restore it. If it is dry fertilizer, water it in time without rain.
(3) Pruning Each year, pruning is conducted every winter and spring, and the excess sprouts and side branches near the ground are cut off to make the stems straight and stout, and improve the ventilation and light transmission in the forest. After fruit harvesting, pests, weak branches, and dense lateral branches should be trimmed. Branches cut from pruning can be selected for Guizhi for medicinal purposes.
(D) The wooded trees retained by the open-leaved cinnamon forest should be gradually thinned or appropriately shucked to mature the cinnamon when they grow into adult trees.

Long distance LiDAR sensor IT03M series are particularly easy to communication thanks to their fixed connector, which can be plugged it up and off by yourself. Voltage is wider from 3.3v before to 3.6v. Low power consumption feature makes it beceome a very competitive, high performance-price ratio, long range Laser Distance Sensor.
