The invention relates to the field of medicine, in particular to a composition for preventing and treating respiratory tract infection of livestock and poultry and a preparation method of the composition. Firstly, one part of honeysuckle, one part of isatis root and one part of liquorice are taken, and water is added for decoction twice; 8 times of water is added for the first time, 6 times of water is added for the second time, a slight boiling state is kept for 2 hours after the water is boiled each time, and then the water is filtered by a 200-mesh filter screen while the water is hot. And merging the two filtrates, fully and uniformly mixing, concentrating until each milliliter of the filtrate is equivalent to 1g of the crude medicine, and then refrigerating for 24 hours. Filtering with a paper pulp plate, complementing the loss caused by operations such as filtering, and refrigerating for 24 hours again. After the refrigeration is finished, adding the second composition into the first component according to the proportion of 3%, uniformly mixing, sterilizing for 30 minutes by adopting circulating steam, and then carrying out quality inspection and filling to finally obtain a finished product.

This invention discloses a method for cultivating disease-resistant and robust seedlings of greenhouse vegetables. This method introduces a compound prebiotic disease-resistant and seedling-strengthening agent, which contains chitosan, trehalose, specific plant extracts, and the innovative compound indolethiazole. Its application methods cover everything from soaking seeds in a specific dilution solution to root irrigation during the seedling stage and combined foliar and root irrigation treatment before transplanting. Supplemental spraying is also performed after transplanting when adverse environmental conditions occur. This method uses prebiotics to support beneficial rhizosphere microbial communities to inhibit pathogens and utilizes the synergistic effect of the active ingredients in the agent to activate the plant's systemic resistance when necessary. This achieves bidirectional synergistic regulation of promoting seedling growth and enhancing disease resistance, effectively cultivating robust and stress-resistant high-quality seedlings.

The invention relates to the technical field of garlic planting, in particular to garlic seedling emergence equipment for agricultural production and a seedling emergence method.The garlic seedling emergence equipment comprises a mulching film, a seedling guide cylinder assembly and a phase change heat preservation assembly, a circular through hole is formed in the mulching film, the seedling guide cylinder assembly comprises a plurality of vertically-arranged seedling guide cylinders, and the lower ends of the seedling guide cylinders penetrate through the circular through hole and are inserted into soil; the seedling guide cylinder comprises an inner cylinder and an outer cylinder, the outer cylinder sleeves the outer side of the inner cylinder, an annular interlayer cavity is formed between the outer cylinder and the inner cylinder, the annular interlayer cavity is filled with the phase change heat preservation assembly, an annular flange is arranged in the middle of the outer side of the outer cylinder, and the annular flange is attached to the lower surface of the mulching film and is in sealed connection with the edge of the circular through hole in a hot pressing welding mode; a covering film is arranged at the top opening inside the inner cylinder; a closed micro-domain space is defined by the seedling guide cylinder, the mulching film and the covering film together, air convection heat exchange is reduced, the phase change heat preservation unit continuously adjusts the temperature fluctuation range in the cylinder, and normal growth and development of seedlings in a low-temperature environment are guaranteed.

The invention discloses application of a pepper CaFtsH1 metalloproteinase gene in pepper seedling stage leaf development, and belongs to the field of plant genetic engineering, a full-length nucleotide sequence of a rape CaFtsH1 gene is shown as SEQ ID NO: 1, and a specific fragment selected by VIGS is shown as SEQ ID NO: 2. The gene is subjected to virus-induced gene silencing in a pepper material Z14, and a silencing single plant has a whitened leaf phenotype and only contains very few chloroplasts with abnormal development, so that the gene is very important for the development of chloroplasts and leaves of pepper seedlings; therefore, the method has a certain application prospect in pepper molecular design breeding and high-photosynthetic-efficiency breeding.
