The invention relates to the technical field of soil ecology, and particularly discloses a method for quantifying the density of topsoil habitat soil arthropods based on a trap method.The method comprises the following steps that S1, trap method sampling is conducted, specifically, when a soil arthropod sample is collected, a soil auger is used for digging out a trap, a trap cup containing preserving fluid is placed in the trap for soil animal investigation, and the soil arthropod sample is collected; the time duration is one week which is used most widely in the literature; s2, sampling by a digging method: when a soil arthropod sample is collected, placing a prepared sampling frame of one square meter on sampling soil, digging and collecting soil animals with the depth of 10cm in the sampling frame, picking large arthropods by using a hand picking method, and separating medium soil animals such as springtails, mites and insects by using a dry funnel method. According to the method for quantifying the density of the surface soil habitat soil arthropods based on the trap method, the actual soil excavation area can be reduced to the maximum extent, the damage to the soil structure of a sampling field is reduced, and the possibility is provided for long-term experiments.

A biological control method for centipede breeding belongs to the field of special economic animal breeding technology. This invention uses a compound probiotic strain of *Trichoderma longicornis*, *Streptomyces flavus*, *Bacillus subtilis*, *Bacillus licheniformis*, *Clostridium butyricum*, and lactic acid bacteria, which is fully incorporated into the breeding substrate. After 24-72 hours of static setting, the bacteria fully colonize and form a stable antibacterial state. The bacterial community can remain dormant during periods of nutrient deficiency, low-temperature overwintering, or year-end static setting, and will revive upon contact with organic matter. The method is supplemented with springtails and pink woodlice, which preferentially consume harmful bacteria, clean up uneaten feed, and primarily feed on and decompose centipede feces, forming a mutually beneficial symbiotic relationship with the biocontrol bacteria. Their feces further nourish the bacterial community, extending the stable effective period of the bacterial community from 2 months to 4-6 months or more. Simultaneously, probiotics and vitamins are added to the feed to strengthen the centipede's constitution. This invention constructs a three-dimensional synergistic prevention and control system that integrates matrix inhibition of pathogenic bacteria, environmental residue removal, and internal administration for enhanced protection. This system enables drug-free ecological disease control, significantly reduces the incidence of diseases such as green muscardine, and improves the survival rate of centipede farming. It is suitable for large-scale centipede farming.

The present invention belongs to the field of lateral membrane group begonia breeding technology, and specifically relates to a lateral membrane group begonia hybrid offspring sowing method, comprising the following steps: S1. harvesting seeds; S2. preparing a matrix; S3. matrix disinfection; S4. sowing; S5. cultivating, and after sowing, placing the sowing container in an environment with a temperature of 20-26°C, a light of 1000-5000 lux, and a photoperiod of 10-16 hours / day. The lateral membrane group begonia hybrid offspring sowing method of the present invention, by performing multiple rounds of all-round disinfection and prevention of the matrix, sowing container, and seeds, etc. by different methods, can reduce the incidence of fungi, bacteria, mosses, springtails, and nematodes from an overall 30-50% to less than 10%, and increase the overall germination rate of hybrid offspring seeds from less than 30% to more than 50%. Combined with compound slow-release fertilizer, the growth rate of hybrid offspring seedlings is increased by 20-30%, and the efficiency of hybrid breeding is significantly improved.

The invention relates to a super-amphiphobic conical structure for rapidly transporting underwater oil drops and a preparation method thereof.The super-amphiphobic conical structure comprises a bionic coupling conical structure formed by a conical structure imitating a cactus spine structure and a plurality of springtail skin surface mushroom-shaped reentrant structures on the surface of the conical structure; the cone height of the conical structure and the distance between the adjacent mushroom-shaped reentrant structures in the generatrix direction of the conical structure are optimized, the surface of the bionic coupling conical structure is covered with the super-amphiphobic coating, the reentrant characteristic is combined with the super-amphiphobic coating to provide a thick and stable air layer for the structure surface in the underwater environment, the water resistance is effectively reduced, and the service life of the bionic coupling conical structure is prolonged. Stripe-shaped groove micro-channels imitating a sarracenia micro-channel can be further distributed on the surface of the conical structure, underwater oil drops can be rapidly transported, the fastest speed of underwater transportation of 0.2 mu L of oil drops can reach 135 mm / s, pollution of soybean oil and the like can be prevented, repeated recycling is facilitated, and the conical structure is suitable for multiple fields of oil-water separation, micro-fluidic chips and the like.
