The latest course on planting techniques and methods of camphor trees

Cinnamomum camphora is a large evergreen tree of the genus Cinnamomum in the Lauraceae. It is produced in the south and southwest of China. It adapts to an altitude of less than 1800 meters. It can reach 1000 meters above sea level in the south and southwest of the Yangtze River. It grows in sunny slopes, valleys and riparian flatlands with fertile soil in the subtropics. It has a very high cultivation value. Let's take a look at camphor tree planting techniques.

Growth habits of camphor trees

Camphor trees like light, shade tolerance, warm and humid climate, cold tolerance is not strong, suitable for growing in sandy loam, more resistant to water and moisture, but when transplanting should pay attention to maintain soil moisture, waterlogging is easy to cause rotting roots to die of hypoxia, but not resistant to drought, barren and saline-alkali soil. The main root is well-developed, deep-rooted and resistant to wind. Strong sprouting ability, resistant to pruning. The growth rate is medium, and the tree is as large as an umbrella, which can hide from the shade and cool.

Seed collection of camphor tree

Camphor tree fruit falls off when it is ripe, and birds peck at it. Every year from October to December, mature seeds are collected and stored in sand, and they can be germinated and sown at the beginning of March. Seeds should choose 40-60-year-old mother trees with rapid growth, robust, obvious trunk, straight, high branches, developed crown, free of diseases and insect pests, and bearing much fruit, with 720008000 seeds per kilogram, germination rate 7080%, and sowing amount 1015kg per mu.

Soil preparation and fertilization in seedling land

The first ploughing and harrowing of camphor tree nursery land is carried out at the beginning of winter, and the second ploughing and harrowing is carried out before sowing, and sufficient base fertilizer is applied. The basic fertilizer is generally 1500 to 2000 kilograms per mu of rotten barnyard manure or 50 kilograms of carbon amine, 50 kilograms of phosphate fertilizer and 150 kilograms of vegetable cake. then build a high bed, generally the bed is 35 to 50 centimeters high and 1.2 meters wide.

Accelerated germination and sowing of seeds

Cinnamomum camphora trees need to accelerate germination before sowing, and the seeds can be soaked in warm water of 50 ℃. After cooling in warm water, the seeds can be soaked in 50 ℃ water for 3 times and 4 times, which can make the seeds germinate 10-15 days earlier. The row spacing of strip sowing is about 20 cm, and the sowing amount is 1015kg per mu. After sowing, the soil is covered with straw or plastic film to keep the topsoil of the seedling bed moist to facilitate seed germination.
