This utility model discloses a multi-layer diversion type rainproof device for the fresh air inlet of an air conditioning unit, relating to the field of air conditioning technology. It includes two side plates, with multiple layered partitions installed between them. Each layered partition is sloped towards the air inlet side. In use, the sloped partitions effectively trap fine water particles, allowing them to flow downwards and exit from the device from the left and right, ensuring that rainwater does not enter the air conditioning unit. Furthermore, the dual-direction air inlet structure, with upper and lower insect-proof net components at each inlet, provides protection against sand, insects, animals, and rain. When rainwater comes into contact with the upper and lower insect-proof net components, most of it is intercepted and does not enter the air conditioning unit. The device is compact, occupies little space, and has high mechanical strength, making it particularly suitable for air conditioning units with large fresh air volumes.

The invention discloses a method for preparing a zinc-containing polypeptide biocontrol bacterial fertilizer through combination of microorganisms and an enzyme method, and belongs to the technical field of microbial fertilizers. The method specifically comprises the following steps: (1) inoculating a candida utilis strain into a zinc-rich culture medium to obtain a candida utilis culture solution; (2) adding a protease compound into the solution obtained in the step (1) to obtain a zinc-containing polypeptide solution; (3) adding a bacillus thuringiensis mixture into the mixture obtained in the step (2) to obtain zinc-containing polypeptide biocontrol bacterium fermentation liquor, and concentrating the zinc-containing polypeptide biocontrol bacterium fermentation liquor to obtain the zinc-containing polypeptide biocontrol bacterium fertilizer. According to the invention, crops, microbial nutrition, biological control and soil improvement are organically combined, three-in-one functional combination is realized, and compared with a single-function fertilizer, the compound fertilizer has a more remarkable comprehensive effect.

The invention discloses a Chinese wolfberry fruit pest green prevention and control method based on functional plants. The invention discloses a green prevention and control method for Chinese wolfberry pests based on functional plants. The green prevention and control method comprises the following steps: 1) arranging functional plant planting belts on the edge of a Chinese wolfberry plantation or two sides of a working road; 2) selecting seeds of functional plants, and sowing the seeds on the functional plant planting belt to obtain a functional plant belt; the functional plant is selected from at least one of astragalus membranaceus, radices stellariae dichotomae and scutellaria baicalensis; 3) performing water and fertilizer integrated management on the functional plant zone and the wolfberry plantation; 4, a suspended sticky trap is arranged above the functional plant zone, the migratory flying amount of the winged aphids is monitored, the occurrence trend of the winged aphids on the Chinese wolfberry branches in the field is predicted on the basis of the winged aphid trapping amount, and accurate prevention and control of Chinese wolfberry pests are guided. The Chinese wolfberry aphid breeding and harm can be reduced, the plant type and ecological niche of Chinese wolfberry are complementary, the natural enemy diversity of Chinese wolfberry pests is improved, and the pests on the Chinese wolfberry are controlled.
