The invention discloses a seedling raising method for oil-used peony seeds. The method comprises the steps of (1) selecting seeds; (2) soaking the seeds for disinfecting; (3) treating the oil-used peony seeds of step (2) by using cold plasma generated by atmospheric dielectric barrier discharge for 50-60 seconds; (4) preparing a treatment solution containing 0.25mg / L of gibberellin, 2mg / L of indoleacetic acid and 3mg / L of calcium chloride; (5) performing variable temperature stratification: mixing the oil-used peony seeds treated in step (3) with fine sand, perlite and vermiculite in a ratio of 1:(3-5):(1-2):(1-2), adjusting the humidity to 40-50%, and performing variable temperature stratification in a constant temperature incubator according to three stages; (6) sowing; and (7) performing seedling management. By adopting the seedling raising method for the oil-used peony seeds, seed dormancy can be effectively broken during breeding, so that seeds are quickly germinated, germination of seeds is accelerated, the emergence rate of seeds is improved, the emergence time is shortened, the emergence is even, and the growth indexes of young seedlings such as fresh weight, plant height, root system and the like are improved to different degrees; and the method does not have pollution to the environment.

The invention discloses application of bacillus licheniformis to the promotion of rooting or growth of semen trigonellae tissue culture seedlings. The application comprises the bacterium activation of a raw material entrocoor dinatibiogen and inoculation to successive semen trigonellae seedlings in form of bacillus licheniformis liquid, a large number of separation, purification and strain identification steps are eliminated, the addition of any exogenous hormones is avoided, the cost is low, the operation is easy, safe and nontoxic, and remarkable effects are achieved; the rooting rate of the inoculated semen trigonellae tissue culture seedlings is remarkably increased, indexes such as plant height and leaf area are also improved, the survival rate after fungal contamination is greatly increased, and the rooting quality of the semen trigonellae tissue culture seedlings is remarkably improved.

The invention belongs to the technical field of microorganisms, and in particular relates to a heavy metal-resistant Burkholderia and application thereof. The invention provides a Burkholderia sp. HXC-1, the highest tolerance concentration of the Burkholderia HXC-1 to copper is greater than 150mg / L, and can effectively remove The removal rate of copper in the heavy metal polluted environment is as high as 92.57%, which can realize the remediation of heavy metal polluted soil; the Burkholderia HXC-1 has a growth promoting effect on the growth of alfalfa seedlings under copper pollution, and can significantly promote the growth of alfalfa seedlings. Stem length and plant height of alfalfa seedlings, and when the copper concentration was 450 mg / L, after the alfalfa seedlings were treated with the described Burkholderia HXC-1, the stem length and plant height were untreated 46 times and 2.89 times; when the copper concentration was 500mg / L, the alfalfa seedlings were treated with the described Burkholderia HXC-1, and the stem length and plant height were 67.96 times, 2.44 times, has a significant growth-promoting effect, and has broad application prospects.
