The (light) compensation point is the light intensity on the light curve where the rate of photosynthesis exactly matches the rate of cellular respiration. At this point, the uptake of CO₂ through photosynthetic pathways is equal to the respiratory release of carbon dioxide, and the uptake of O₂ by respiration is equal to the photosynthetic release of oxygen.
Method for evaluating conditions for recovery of submerged plants and construction thereof
ActiveCN117668411BSustainable biological treatmentComplex mathematical operationsMicroorganismPlant population
The application discloses a kind of submerged plant recovery condition evaluation and its construction method, belong to environmental engineering technical field, steps are as follows: measure or estimate water surface illumination intensity and measure water transparency;Based on underwater light field calculation method obtains underwater light field information in recovery area;Whether it has recovery condition is evaluated in combination with plant population and community light compensation point data;For the area without condition, wind wave influence is evaluated using wind wave influence evaluation method on sediment, and combined with ecological enclosure, fish removal, bottom comprehensive improvement aid and microbial compound microbial agent measures, improve water transparency and other water quality conditions, complete submerged plant recovery.The application is simple, efficient, and the construction measures are scientific, reasonable, economical and convenient, which can effectively improve the survival rate of submerged plants.

Plant growth suppression method and plant growth suppression system
The plant growth suppression method according to the present disclosure includes a step of, within a single day, irradiating a plant with suppression light including left circularly polarized light during a second time period that is different from a first time period during which the plant is irradiated with growth light. The photon flux density of the suppression light is a value below the light compensation point of the plant.
