The application discloses a method for promoting growth of cymbidium on a steel slag flat bed based on microbial organic matrix, and belongs to the technical field of steel slag resource utilization. The application inoculates eight kinds of bacillus agents with different concentrations on the bacterial residue to prepare the organic matrix, and then covers the matrix on the converter slag to promote the growth of cymbidium on the converter slag, and selects the bacillus strain with the best growth promotion effect and the most suitable inoculation concentration. The results show that after being inoculated with bacillus megaterium, bacillus polymyxa and bacillus mucilaginosus, the sucrose activity of the soil is enhanced; the hydrogen peroxide activity of the soil in the four groups of treatments inoculated with the bacillus agent is stronger than that in the control group; the application of the bacillus megaterium, bacillus polymyxa and bacillus mucilaginosus enhances the urease activity in the soil; the inoculation of the bacillus megaterium promotes the release of Ca and P elements in the soil and the absorption of Ca, P, Mg, Mn and Si elements by the plant.

This invention relates to the field of fluorescence detection technology, specifically disclosing a dual-colorimetric fluorescent probe for detecting methyl orange, its preparation method, and its application. The probe is prepared by in-situ synthesis of carbon dots and copper nanoclusters. The carbon dots are synthesized from Bermuda grass as a precursor via a hydrothermal method, and the copper nanoclusters are obtained by reducing copper ions with penicillamine and bovine serum albumin as dual stabilizers. The dual-colorimetric fluorescent probe provided by this invention has a detection limit for methyl orange as low as 0.06 μM, exhibiting good selectivity, stability, and anti-interference ability. It can be applied to the spiked recovery detection of methyl orange in actual water samples and can achieve visualized semi-quantitative analysis through filter paper loading, making it suitable for rapid on-site screening.

The invention provides a lawn based on lake bottom mud and a construction method and application thereof, and belongs to the field of urban ecological engineering and environmental engineering.The construction method comprises the following steps that S1, a base layer is laid, specifically, lake bottom mud is subjected to particle screening, and bottom mud with the particles larger than 30 mm serves as the base layer to be laid; s2, a bearing layer is laid, specifically, asphalt concrete is laid on the base layer to serve as the bearing layer, and the bearing layer is formed by wrapping round stones with asphalt; s3, laying a buffer layer: 4-5 weeks after the bearing layer is laid, laying lake bottom mud with particles smaller than 30mm on the bearing layer as the buffer layer; s4, planting layer construction: sowing lawn grass seeds, wherein the lawn grass seeds are selected from at least one of ryegrass or cynodon dactylon; according to the method, the lake bottom mud is used as a main planting substrate, so that the purpose of treating waste with waste is achieved, the bottom mud treatment cost is reduced, and a safe, economical and feasible path is provided for lake pollution treatment and ecological restoration.

The application belongs to the technical field of plant stress resistance regulation, and particularly relates to application of kynurenic acid in improving salt stress adaptability of cynodon dactylon. The application finds that, before and / or during salt stress, exogenous application of kynurenic acid to cynodon dactylon can significantly reduce the degree of oxidative stress (H2O2), the level of membrane lipid peroxidation (MDA) and the content of osmotic regulator substance proline, effectively relieve salt damage reaction and improve the adaptability of cynodon dactylon in a high-salt environment. The method is simple in operation, suitable for plant remediation and environmental protection planting in saline soil, and has a good application prospect.

The application discloses a method for annual efficient production of centipedegrass seedling, which comprises the following steps: building a multi-layered culture shelf, preparing a seedbed, sowing seedlings, managing a rooting stage, managing a seedling forming stage, pre-harvest management, harvesting seedlings, and post-harvest management. According to the technical scheme, the centipedegrass seedlings can be rapidly propagated under the precise environment control of temperature and light by building a multi-layered shelf indoors, and the seedlings can be harvested 6-8 times per year after one-time planting, so that the annual efficient production of the centipedegrass seedlings is realized, sufficient seedling materials are provided for national land greening, sports field lawn planting and ecological restoration, and remarkable economic benefits are achieved.

The invention belongs to the technical field of herbicides, and particularly relates to an efficient weeding composition for airport lawn broadleaf weeds and application thereof.The efficient weeding composition is prepared from carfentrazone-ethyl, chipton sodium, fluroxypyr-mepthyl and 2, 4-D isooctyl ester as main effective components, by matching with a special auxiliary agent composed of xanthan gum, polyethylene glycol and the like and a pesticide application method matched with an airport scene, efficient prevention and control of rumex plicata broadleaf weed plants are achieved, and the weeding composition is safe, free of phytotoxicity and low in soil residue on common airport turfgrass such as cynodon dactylon, bluegrass, agrostis pilosa and festuca arundinacea. The device can cut off a grass-insect-bird ecological chain of an airport, remarkably reduces the bird strike risk, is suitable for lawns of various airport flying areas, and has extremely high popularization value.

This invention provides a turfgrass based on lake sediment, its construction method, and its application, belonging to the field of urban ecological engineering and environmental engineering. The establishment method is as follows: S1, Base layer laying: The lake sediment is screened for particles, and sediment with particles >30mm is used as the base layer; S2, Load-bearing layer laying: Asphalt concrete is laid on the base layer as the load-bearing layer, which is composed of asphalt-coated rounded pebbles; S3, Buffer layer laying: 4-5 weeks after the load-bearing layer is laid, lake sediment with particles smaller than 30mm is laid on the load-bearing layer as a buffer layer; S4, Planting layer construction: Turfgrass seeds are sown, and the turfgrass seeds are selected from at least one of ryegrass or bermudagrass. This invention uses lake sediment as the main planting substrate, realizing waste-to-waste treatment, which not only reduces the cost of sediment disposal, but also provides a safe, economical, and feasible path for lake pollution control and ecological restoration.
