The Litsea coreana (Cercidiphyllum japonicum) is a deciduous tree of Litsea of Litseae, and is mainly distributed in southwest part of Shanxi, henan, shaanxi, gansu, anhui, zhejiang, jiangxi, hubei and Sichuan of China. The aromatic tree is a single plant of the wiggles of the third-stage ancient tropical plant and is an ancient original woody plant. The tree has unique taxonomic status in plant groups, and can provide important scientific value for the origin and phylogenetic development of the belonging plants. The fructus Litseae can be used as medicine, bark and leaf can be used for preparing tannin extract, and leaf can be used for preparing flavoring enhancer. In addition, the wood grain of the continuous aromatic tree is straight, the structure is fine, the continuous aromatic tree is not only a rare and precious wood species, but also an important coinage tree species, the tree pose is graceful, the leaf shape is peculiar, the Ji Xiangbian is rich, and the continuous aromatic tree has higher ornamental value in gardens.
The natural updating is difficult, the resources are rare, the natural updating is endangered, the natural updating is listed in Chinese rare endangered plant directory, chinese plant red book and national important protection wild plant directory, and the natural updating is a national second important protection wild plant species. For many years, scientific researchers try to artificially propagate the aromatic tree in various modes such as cuttage, tissue culture, seed sowing and the like, but due to fewer nutrient substances carried by seeds and severe requirements of seedlings on the cultivation habitat conditions, the nursery yield of the seedlings is lower, and the nursery quality is poor. Therefore, strong seedling cultivation becomes a technical bottleneck for propagation and scale utilization of the strand of the tree.
At the present stage, the seedling strengthening technology of the strand-leaf tree is mainly based on methods of fertilizing and strengthening seedlings, adjusting growth hormone and spraying biological agents to strengthen seedlings, but long-term excessive fertilization can cause soil acidification, salinization and unbalance of soil microorganisms; improper use of auxins can affect the growth and development of the strand, even resulting in malformation of plants; biological agents are of a wide variety, and improper use of the type and concentration of the agent can cause poor plant growth or adverse effects. In addition, the reagents used in these techniques inevitably pollute the environment and increase carbon emissions during the preparation and use.
Therefore, how to provide a safer, efficient and environment-friendly method for improving the seedling quality of the tree, which is a technical problem to be solved by the technicians in the field.
Disclosure of Invention
In view of the above, the invention provides a method for improving the seedling raising quality of the aromatic tree, which combines greenhouse culture and shaking culture, effectively regulates and controls biomass distribution in the growth process of the aromatic tree seedling, obviously improves the ratio of ground diameter to plant height, improves the stem robustness and the ratio of underground biomass, and achieves the effects of strengthening seedlings and improving the quality of the seedlings.
In order to achieve the above purpose, the present invention adopts the following technical scheme:
a method for improving the quality of seedlings of Litsea Coreana comprises placing the seedlings of Litsea Coreana on a shaking table, shaking at uniform speed, and culturing to obtain high-quality seedlings of Litsea Coreana.
The method for improving the seedling quality of the strand-shaped tree comprises the following steps:
(1) Matrix pretreatment and seed sowing: sterilizing the matrix for raising seedlings of the tree, filling the matrix into a seedling raising container, watering fully, and sowing into germinated seeds;
(2) Seed pre-culture: placing the sown seedling raising container in a greenhouse, and culturing under full illumination until the leaves of the seedlings grow to 4-5 pairs to obtain pre-cultured seedlings;
(3) Culturing seedlings by shaking: the culture conditions are kept unchanged, the pre-cultured seedlings are placed on the shaking table after sunset, the seedlings are cultured in a shaking mode at a constant speed, and the shaking table is closed after sunset, so that the quality of the seedlings can be improved.
Preferably, the preparation method of the strongpoint-tree seedling substrate in the step (1) comprises the following steps: perlite, vermiculite, peat: the coconut husk is prepared by mixing according to the volume ratio of 1:1:2:2; the sowing depth of the seeds is 0.5-1mm.
Preferably, the greenhouse full-illumination culture conditions in the step (2) are as follows: the temperature in the daytime is 25-30 ℃, the air humidity is 50-80%, the temperature in the night is 15-18 ℃ and the air humidity is 50-80%.
Further preferably, the greenhouse full-illumination culture conditions in the step (2) are as follows: the temperature of the air is 28 ℃ in the daytime, the air humidity is 55%, the temperature of the air is 17 ℃ at night and the air humidity is 75%.

Compared with the prior art, the invention has the following beneficial effects:
it is generally believed that the quality of seedlings grown in the field is better than that of seedlings grown in the greenhouse, particularly in terms of the degree of stem thickening, root system development, etc., which is largely caused by the lack of blowing of seedlings in the greenhouse. On the other hand, greenhouse seedling culture has great advantages in the aspects of growth environment control, seedling growth speed and the like, and is incomparable with field seedling culture. In view of the above, the invention combines greenhouse culture and shaking culture, not only can mechanically shake seedlings, but also can effectively regulate and control the seedling raising environment to avoid excessive water loss of the seedlings caused by excessive wind speed, and the like, thereby realizing effective regulation and control of biomass distribution in the growth of the seedlings of the Chinese parsley, remarkably improving the ratio of ground diameter to plant height, improving the thickness of stems and the occupation ratio of underground biomass, and achieving the effects of strengthening seedlings and improving the quality of the seedlings.

60 seedlings of the Litsea coreana (average plant height 12cm, average ground diameter 1.4mm, average 4 pairs of leaves for each plant) with consistent growth vigor are taken and placed in a full-illumination greenhouse for adaptive cultivation for 1 week. The culture conditions of the full-illumination greenhouse are as follows: day 28 ℃, air humidity 55%; the night temperature is 17 ℃, and the air humidity is 75%. After the end of the acclimatization, seedlings were equally divided into 3 groups.
Test group: after sunset, placing the seedlings of the Chinese juniper and the seedling raising container on a shaking seedling bed at 80rpm, shaking at a constant speed, and closing the shaking table after sunrise for the next day;
control group 3: similar to the test group, only the shaker speed was varied, set at 40rpm;
control group 4: similar to the test group, only the shaker speed was varied, set at 120rpm;
the environmental condition settings of the three groups during the trial were consistent with the acclimation period and the trial continued for 2 weeks. After the test is finished, the 3 treated plant heights, the ground diameters and the ratio of the ground diameters to the plant heights are counted, and the test results are shown in Table 7;
TABLE 7 influence of shaking speed on the growth traits of seedlings of Styrax
| Height of plant (cm) | Ground diameter (cm) | Ground diameter/plant height | |
| Test group | 29.61±3.27 | 0.45±0.15 | 0.015±0.002 |
| Control group 3 | 35.74±2.54* | 0.42±0.02 | 0.012±0.001* |
