The application relates to a method for breeding Scirpus planiculmis nutrient bulb based on hydrological regulation, and relates to a breeding method for Scirpus planiculmis nutrient bulb. The method is used to solve the problems of high cost and strong uncertainty in the existing Scirpus planiculmis bulb breeding process. The method comprises the following steps: S1, seed source collection and screening; S2, culture medium and container screening and preparation; S3, Scirpus planiculmis bulb sowing control; S4, stage hydrological regulation; and S5, Scirpus planiculmis bulb harvesting. The application sets up differential water level management based on different growth and development stages of Scirpus planiculmis, can significantly improve the quantity and quality of Scirpus planiculmis bulb breeding, and realizes bulb large-scale proliferation. The application adopts a 26cm-diameter and 30cm-depth gallon pot to breed Scirpus planiculmis nutrient bulb, about 200 bulbs can be harvested from each pot, the dry weight of the bulbs in each pot is about 360-420g, and the breeding efficiency is stably improved. The application can be used in the fields of laboratory breeding, scientific test and degenerated Scirpus planiculmis wetland ecological restoration.

The invention discloses a method for improving saline-alkali stress resistance of bolboschoenus planiculmis seedlings, which specifically comprises the following three aspects: bolboschoenus planiculmis corm treatment and seedling staged water management, saline-alkali resistant composite nutrient solution preparation and application, and soil microenvironment optimization. According to the bolboschoenus planiculmis corm treatment and seedling staged water management, a dynamic water supplementing strategy is designed according to different physiological requirements in the germination period; the salt damage is relieved and the metabolic activity is enhanced through the preparation and application of the salt and alkali resistant composite nutrient solution through an ion antagonist and an osmotic regulation substance; in soil microenvironment optimization, the surface salinity concentration is reduced by using the design of a covering material and a planting layer. According to the technical scheme, through three-dimensional regulation and control of the water-nutrient-soil microenvironment, on the premise of not depending on physical means, synergistic improvement of corm germination and stress resistance under saline-alkali stress is achieved, the technical cost is low, and large-scale application in saline-alkali wetland vegetation recovery is easy to achieve.
