This invention discloses a method for increasing the lignin content in the roots of Lauraceae fruit trees, belonging to the field of plant physiological regulation technology. To increase the lignin content in the roots of Lauraceae fruit trees such as avocado trees, this invention employs the following techniques: application of a lignin-synthetic nutrient-enhancing solution; directional pulsed electric field treatment to enhance the permeability of the fruit tree's epidermal cell membranes; activation of key enzymes in phenylpropanoid metabolism by irradiation with specific wavelengths of ultraviolet light; and synergistic application of mechanical stress technology to stimulate and induce vascular tissue differentiation. By treating the roots of Lauraceae fruit trees, not only can the lignin content in the root system be increased by more than 30%, but the root system's stress resistance and mechanical strength can also be improved by more than 45%, while maintaining normal physiological metabolism of the plant. This provides a new solution for lodging-resistant cultivation and root rot prevention in Lauraceae fruit trees.

The invention discloses an agrobacterium rhizogenes mediated transformation method for transgenic hairy roots of complete leaves of cinnamon. The stable and repeatable agrobacterium rhizogenes-mediated hairy root transformation system is established for the first time aiming at the cinnamomum cassia which is a cinnamomum camphora woody plant with difficulty in genetic transformation, and the technical difficulty in gene function research is solved. It is found that in cinnamon, only on the premise that the overall integrity of leaves is kept, the stable agrobacterium rhizogenes infection and hairy root induction can be achieved by slightly scratching the leaves perpendicular to leaf veins in cooperation with an agrobacterium infection solution with a certain concentration and vacuumizing treatment, and the hairy root induction effect is achieved. And a stable material is provided for subsequent hairy root induction of a complete transgenic regeneration plant. The agrobacterium rhizogenes-mediated hairy root transformation method provided by the invention can efficiently induce plants to generate transgenic roots, lays a foundation for mining good cinnamon genes in the future, and provides a convenient and rapid way for researching biological functions of related genes in the roots.

The invention discloses a strain of extreme oriental pseudomonas LJ-6 and application thereof in prevention and control of mulberry diseases. The extreme oriental pseudomonas disclosed by the invention is preserved in the Guangdong Microbial Culture Collection Center on June 18, 2024, and the preservation number of the extreme oriental pseudomonas is GDMCC (China General Microbiological Culture Collection Center) NO: 64766. The extreme pseudomonas orientalis LJ-6 has a very good antagonistic effect on bacterial pathogenic bacteria such as lauraceae bacteria, pantoea anantoea, Klebsiella compacta and enterobacter cloacae and fungal pathogenic bacteria such as fusarium oxysporum, curvularia and colletotrichum truncatum, and has a very good antagonistic effect on plant diseases caused by plant infection by the pathogenic bacteria. The composition has good prevention and control effects on mulberry bacterial wilt, mulberry bacterial wilt, mulberry leaf spot, mulberry anthracnose and the like, and is safe and effective. Therefore, the extreme oriental pseudomonas LJ-6 disclosed by the invention has good application prospect and value in the aspects of preventing and controlling plant diseases such as mulberries and preparing disease prevention and control preparation products.

The invention discloses a method for increasing the lignin content of roots of lauraceae fruit trees, and belongs to the technical field of plant physiological regulation and control. In order to improve the content of lignin at the roots of the lauraceae fruit trees such as butyrospermum parkii, lignin is applied to synthesize nutrition enhancing liquid, the fruit tree epidermis cell membrane permeability is enhanced through directional pulsed electric field treatment, and phenylpropane metabolism key enzyme activity is activated through specific wave band ultraviolet irradiation; the root of the lauraceae fruit tree is treated, so that the lignin content of the root system can be increased by 30% or above, the stress resistance and mechanical strength of the root system can be increased by 45% or above, meanwhile, normal physiological metabolism of the plant is kept, and the survival rate of the lauraceae fruit tree is increased. And a new solution is provided for lodging-resistant cultivation and root rot prevention of the lauraceae fruit trees.

The invention discloses a cultivation method of a cyclobalanopsis gilgii and phoebe zhejiangensis mixed forest. The cultivation method comprises the following steps: selecting slightly acidic red soil with a gentle slope at the altitude of 0-250m; cyclobalanopsis rubra, phoebe zhejiangensis and other Lauraceae woody plants are planted, the plant row spacing is 1.6 m * 1.6 m, strip-shaped mixed planting is carried out, and the same-age forest is cultivated into a stable and high-quality precious wood tree species mixed forest through periodic tending management. According to the method, the mycorrhizal tree species of cyclobalanopsis gilgiana and the non-mycorrhizal tree species of phoebe chekiangensis are planted in a mixed mode, the abundance of endophytic mycorrhizal fungi in soil is increased by means of the symbiotic relationship of the cyclobalanopsis gilgiangensis and the ectomycorrhizal fungi, the nutrient absorption efficiency of the root system of phoebe chekiangensis is improved, meanwhile, the advantage that the phoebe chekiangensis trees grow fast is utilized, light resources are reasonably configured, and the yield is increased. Growth of lateral branches of cyclobalanopsis gilgii is slowed down, the growth rate of trunks is increased, and the yield and quality of dry wood are improved. The method has the advantages of being accurate in cultivation technology, vigorous in forest tree growth, low in production cost and easy and convenient to operate, and has wide application prospects.

The invention discloses a method for transforming an extraneous mangrove plant lauraceae community on a difficult site mud flat, and belongs to the technical field of mangrove plant lauraceae planting. The method comprises the steps of S1, investigating the current situation of mangrove plants; s2, beach protection and repair measures are taken; s3, pruning or felling the lauraceae lauraceae; s4, mangrove forest planting; s5, management and protection; s6, evaluating the effect; the method can update and reconstruct the lauraceae coenoenosis growing in the seawater scouring area, avoids the risk of reformation failure, and is earlier than other conventional methods for reformation and restoration to form forests; after beach protection measures are taken, the mud flat in the restoration area is stable, and sediment loss caused by tidal scour is avoided; an old fishing net is used for enclosure, and sea floating garbage is prevented from entering a remediation area; small blocks are used for soil preparation, original laugui root systems are reserved, crabs and other organisms in forest land in the earlier stage of transformation are few, interference and damage to newly-planted seedlings are reduced, and the planting survival rate of the mangrove seedlings is guaranteed; the seedlings cultivated under the high-salinity environment condition are used for planting, the stress resistance of the seedlings is high, the growth recovery speed is high, and the survival rate is high.
