Problems solved by technology
After the seeds are harvested and sowed, the germination time lasts for a long time. After the seeds germinate and are transplanted into bags, the growth recovery period is relatively slow, and the seedling growth is very prone to problems such as unevenness and low survival rate. The main reason is that the seedling substrate for the growth of Phoebe brevifolia has a great influence

Embodiment 1
[0019] The short-sequence Runnan test seedlings used in this example were collected from the Runnan nursery in Zhaoqing, Guangdong, and were sown in the sand bed of the nursery of the Foshan Institute of Forestry Science in May 2017 in the form of ready-to-harvest and sow. After the seeds germinate, the seedlings are about 3-5cm high and carry out the bagging test for transplanting seedlings. Seedling height, ground diameter, crown width, root system and other indicators reflect the quality of seedlings, while the growth of seedlings mainly depends on the amount of biomass accumulation, while the physical and chemical properties of the substrate have a greater impact on the growth and development of plants. After a large number of tests, the inventor determined that peat soil, coco peat, perlite and organic fertilizer were used as the matrix components for cultivating Phoebe brevifolia.

The invention relates to a seedling raising substrate for promoting growth of machilus breviflora seedlings. The seedling raising substrate comprises the following components in parts by volume: 10-25 parts of yellow subsoil, 40-70 parts of peat soil, 10-25 parts of coco coir, 5-12 parts of perlite and 3-5 parts of organic fertilizer. According to the seedling raising substrate for promoting the growth of the machilus breviflora seedlings, the seedling height of the machilus breviflora can be effectively increased, and the seedling height is increased by about 12.7%-27.5%; the number of leaves is increased by 10%-20%; the ground diameter is increased by 13.8%-24.1%; and the survival rate of transplanted seedlings reaches 100%. The seedling raising substrate for promoting the growth of the machilus breviflora seedlings solves the problem of low natural reproductive capacity of the machilus breviflora, the distribution range of the machilus breviflora is expanded, and large-scale planting, popularization and application can be carried out.
Description
technical field [0001] The invention relates to a seedling-raising substrate for promoting the growth of Phoebe nannuum seedlings, and belongs to the technical field of seedling-raising materials. Background technique [0002] Machilus breviflora (Machilus breviflora) belongs to the evergreen tree of the genus Machilus in the family Lauraceae (Rosaceae). In spring, the young leaves are red and the whole tree is red. It is extremely beautiful and has obvious seasonal characteristics. It can be used as a colorful leaf tree species, as well as a garden ornamental tree species and urban greening street tree. It is an excellent native tree species with great potential for development and application in South China. [0003] The distribution range of the wild species of this tree is relatively narrow, mainly distributed in Guangdong, Hainan, Guangxi, Hong Kong and other places. It likes to grow in alpine dwarf forests with sufficient sunlight. After investigation in Dinghu Mountai...
