Method for culturing seedlings of Phoebe bournei by light soil type mixed matrix

Abstract

The invention discloses a method for culturing seedlings of Phoebe bournei by a light soil type mixed matrix, which comprises the procedures of collecting seeds, sowing seeds, preparing the matrix, transplanting and culturing seedlings. The method comprises the following steps of: sowing seeds from strong and good seed trees which are more than 20 years old into a sand bed; transplanting seedlings into a plastic cup filled with the light soil type mixed matrix including 30-40 parts of yellow soil, 40-50 parts of coconut husk immersed dry material, 14.75-24.5 parts of pond sludge and 0.25-0.75parts of calcium magnesium phosphate fertilizer; cultivating the seeds to obtain good and strong Phoebe bournei seedlings with the height of more than 31-40 cm; and transplanting the seedlings to carry out the forestation. The seedling culturing matrix of the method provided by the invention has good water conversation performance, good fertilizer conversation performance and complete nutrition, the surface is not easy to harden and fewer weeds are existed; the cultivated seedlings are thickset, the growth is fast, the time for culturing seedlings is shortened, the survival rate of the forestation is high and the recovering stage of the forestation is short, so that the method is adapted to the requirement of accelerating a planted forest of the rare and endangered species Phoebe bournei,and has better economic benefits and social benefits.

[0001] The invention belongs to the technical field of sexual reproduction of plants, and relates to a method for raising seedlings of Nannan light soil mixed substrate. Background technique

[0002] Phoebe bournei (Hemsl.) Yang is an evergreen tree of the genus Phoebe in the Lauraceae family. It is a rare and endangered tree species in my country. It was approved by the State Council as a national secondary protected tree species on August 4, 1999. Famous for its excellent quality, its straight trunk, fine wood grain structure, light yellow and fragrant wood, corrosion-resistant but not easy to warp and crack, easy to process, smooth and beautiful beveled surface, and fragrant. Precious timber tree species. However, due to the long-term irrational use and destruction of precious broad-leaved tree resources, coupled with the slow growth of Phoebe natural forests and the long time it takes for forests to become useful, this precious broad-leaved timber tree res...

Embodiment 1

[0020] Select a strong and excellent mother tree over 20 years old, collect seeds at the end of November, collect the seeds with a hook knife that turns purple-brown in the air, soak them in water for 5 days, wash off the outer seed coats, dry them in the shade, spread them on the sand bed, and press them with wooden boards Flat, covered with a layer of 2cm thick fine sand sieved through a 0.2cm sieve. The humidity of the sand should neither be too dry nor too wet. It is advisable to knead it into a ball with your hands and loosen it with your hands. The sand bed is built with a 70cm iron arch shed, covered and sealed with a white plastic film, and then covered with a layer of shading net that shades 60%. Open it every 7 days to check the moisture in the sand bed. If the sand is too dry, pour water. Add 0.1% quicklime according to the weight of coconut bran and mix well, put it into an open-air pool of 4m×3m×2.5m, pressurize it with stones, add water and soak for 9 months cont...

[0022] Choose a strong and excellent mother tree over 20 years old, collect the seeds whose outer testa has turned purple-brown with high-branch shears in early December, and air-dry them, soak them in water for 8 days, wash off the outer testa, dry them in the shade, spread them on the sand bed, and flatten them with wooden boards. Cover with a layer of 1cm thick fine sand sieved through a 0.2cm sieve. The humidity of the sand should neither be too dry nor too wet. It is advisable to knead it into a ball with your hands and loosen it with your hands.
