This invention relates to the field of insect sex pheromone preparation technology, specifically to a method for preparing and applying a sex pheromone and its lure for controlling the Chinese moth *Cyclocarya paliurus*. Using GC-EAD and GC-MS technologies, this invention identified two sex pheromones, Z9-16:Ald and Z9,Z12,Z15-18:Ald, from the gonad extracts of female *Cyclocarya paliurus* moths. The sex pheromone provided by this invention has a clearly defined composition and optimized ratio. The lure preparation process is simple, has a long-lasting effect, and the trap has strong color adaptability. It enables efficient monitoring and green control of *Cyclocarya paliurus*, completely replacing chemical pesticides, is environmentally friendly, and suitable for widespread application in urban gardens and residential areas.

The invention discloses an intelligent decision-making method for a river and lake health recovery scheme based on a progressive ecological restoration theory, and belongs to the field of environmental governance, and the method comprises the steps: deconstructing a target steady state in a river and lake ecological system into a plurality of ecological parameter equilibrium states, and presetting a corresponding response protocol for each ecological parameter equilibrium state, a set of all response protocols forms an ecological response protocol cluster; according to the real-time state of the river and lake ecosystem, a protocol execution sequence is activated and arranged from the ecological response protocol cluster, an elastic failure boundary model is constructed for each ecological parameter equilibrium state, and the elastic failure boundary model is a dynamic state envelope surface; by constructing the dynamic elastic failure boundary model and combining the disturbance memory energy field to accurately identify the toughness challenge event, the limitation of a fixed restoration scheme is solved, the method is effectively adapted to complex scenes of dynamic interference of climate change, human activity and the like of a river and lake ecosystem, and the anti-interference capability of the restoration scheme is improved.

This invention discloses a continuous ultrasonic amplification standing wave field-ozone micro-nano bubble synergistic inactivation device for mariculture, comprising a seawater pretreatment unit, an ozone micro-nano bubble generating unit, an ultrasonic amplification standing wave field-ozone micro-nano bubble synergistic inactivation reaction unit, a multi-parameter effluent detection unit, and a closed-loop control unit connected in sequence. The reaction chamber adopts a three-layer coaxial nested configuration of 316L stainless steel. The inner tube wall has a regular polygonal prism structure, while the outer tube wall has a multi-segment continuously circulating "gradually expanding-constant diameter-gradually contracting" irregular tube structure. High- and low-frequency multi-array ultrasonic transducers are correspondingly arranged on the inner and outer wall surfaces to synergistically construct a blind-zone-free gradient amplification standing wave field. This invention achieves efficient and continuous inactivation of pathogenic microorganisms in mariculture water by targeting and enriching pathogenic microorganisms at the acoustic pressure nodes of the standing wave field, concentrating the excitation of multi-frequency resonant cavitation effects at the acoustic pressure antinodes, and coupling ozone micro-nano bubbles to reduce the cavitation threshold and leverage their high oxidizing properties.

The application discloses a compostable and degradable seedling paper base system and container and a preparation method thereof, and belongs to the technical fields of horticultural seedling containers, paper base forming and biodegradable barrier coating. The system integrates a paper fiber container, an anti-blocking drainage structure and a polyhydroxyaliphatic acid ester-based biodegradable barrier coating. In view of the industry pain point that traditional containers are difficult to maintain wet strength and degradation, the scheme designs a directional failure zone, which ensures excellent wet resistance and structural stability during seedling period, and significantly improves root penetration efficiency and compost disintegration speed after transplanting. Compared with conventional full coverage technology, the system effectively solves the problems of orifice plugging and water accumulation and mold growth, realizes precise timing control of functions from protection to degradation. The product does not contain fluorides, meets the strict ecological compliance requirements, and achieves excellent seedling quality and environmental safety with better material utilization.
