The invention provides an under-forest ecological allium victorialis planting method and application, and the method comprises the following steps: after gibberellin treatment and low-temperature sand storage germination acceleration of seeds, sowing and seedling raising are performed in an under-forest or sunshelter high bed with the canopy density of 0.3-0.5, and 2-year-old seedlings are cultivated; transplanting in early April or late September according to the line spacing of 15 cm and the plant spacing of 4-6 cm, and cultivating to obtain 3-4-year-old strong seedlings; then a forest stand with the canopy density of 0.5-0.7 is selected, and field planting is conducted according to the line spacing of 20-30 cm and the plant spacing of 15-30 cm; through intertillage weeding, fertilization and pest and disease management, seedlings are harvested by adopting a three-year ring harvesting method or tender leaves are harvested by adopting a leaf breaking method. According to the method, the problems of low emergence rate, unstable yield, uneven quality and the like caused by direct planting in a wild environment are effectively solved, high-quality, stable-yield and efficient production of allium victorialis is realized, and a reliable mode is provided for utilization of northern forests and development of under-forest economy.

The present application belongs to the field of plant conservation, more particularly, relates to a composition for relieving waterlogging stress of Allium victorialis L. and application thereof. The composition of the present application is composed of matured cow dung and spermidine solution, the concentration of the spermidine solution is 0.1-1 mmol / L. Before planting Allium victorialis L., the matured cow dung is applied in the field, when the flood season comes and the plant height of Allium victorialis L. reaches about 60-80 cm, by using the conservation method of the composition, the harm of waterlogging stress on Allium victorialis L. can be continuously relieved, the content of proline in the leaf of Allium victorialis L. is increased, the content of malondialdehyde in the leaf of Allium victorialis L. is reduced, and the oxidative damage caused by waterlogging stress is reduced by increasing the activity of antioxidant enzyme in the leaf of the plant.

The application relates to the technical field of ecological protection and restoration, and discloses a multi-star lily and competitive species interaction regulation and population natural renewal restoration method and system, which comprises the following steps: based on multi-period sample plot monitoring data, a multi-star lily-competitive species dynamic model containing non-integer time lag and nonlinear density index is established; nonlinear filtering is adopted to perform state online estimation on noise-containing monitoring data, and state estimation values and uncertainty measurements thereof are output; according to the state estimation values and the uncertainty measurements thereof, rolling optimization regulation and decision-making are performed through scene analysis and weight construction based on gradient difference; the natural renewal restoration potential is evaluated, and the grade of auxiliary measures is determined; and the restoration scheme is dynamically adjusted in a monitoring-estimation-decision-implementation-remonitoring closed loop. The application can be used for competitive regulation and ecological restoration of a multi-star lily degraded population in a karst mountain meadow, and the stability of the multi-star lily degraded population restoration is improved.
