Ganoderma lucidum cultivation method

The invention provides a ganoderma lucidum cultivation method, and belongs to the technical field of cultivation of fungus for edible and medicinal use. The ganoderma lucidum cultivation method comprises choosing of a field, selection of building materials, construction of a permanent greenhouse, consolidation of sand culture bed land, isolation of contact between sand and soil in the field through plastic membranes, sand burying of ganoderma lucidum fungus sticks, laying of spraying pipelines, shading, insect prevention measures, and the like. According to the ganoderma lucidum cultivation method, standardized cultivation of ganoderma lucidum can be achieved, cultivation conditions can be controlled, traditional Chinese medicine quality management code requirements are fitted, a foundation is not needed to be moved every year, and manpower, material resources and financial resources are saved. The ganoderma lucidum fungus sticks are not contacted with the soil, so heavy metal, toxic substances and pesticide residues all can be controlled effectively. Cultivated ganoderma lucidum is stable and high in yield, namely the yield of the ganoderma lucidum is 570-580 kilograms per mu and is increased by 30% or so compared with conventional cultivation, quality is excellent, namely, competitor pollution rates of the fungus sticks and secondary entities are greatly reduced, malformation does not exist in the secondary entities, and the secondary entities cannot be polluted by water and pollutants in the soil, and the ganoderma lucidum cultivation method is popularization and application of ganoderma lucidum standardized cultivation. The ganoderma lucidum cultivation method is also suitable for edible and medicinal fungus of phellinus igniarius, mushrooms, agaric and the like.

Method for preventing water erosion desertification by using biological crust

The invention discloses a method for preventing water erosion desertification by using biological crust, which is to artificially inoculate a biological crust resource onto bare soil surface of a water erosion desertified area and cultivate the biological crust to allow the biological crust to cover the bear soil surface. The method comprises the following steps:1) selecting well developed natural biological crust, and shoving 10 to 30-millimeter-thick crust layer on surface for later use; 2) drying the collected biological crust in shade, removing other materials, crushing, fully stirring and uniformly mixing to obtain the biological crust resource; 3) mixing the prepared biological crust resource with fine soil according to a ratio of 1:(1-2), uniformly spreading the mixture on the soilsurface to be inoculated, covering a small amount of fine soil, and fully watering after the fine soil is covered; and 4) controlling a proper condition to promote the growth of the biological crust,namely watering, topdressing, killing pests and weeding. With the method of artificial inoculation and cultivation, a high-coverage biological crust can be formed in a short period, and the formed biological crust has obvious water and soil holding function; and the method is an effective method for treating water erosion desertification.

Submerged plant modularized growth bed and method for recovering growth of underwater submerged plant

The invention provides a submerged plant modularized growth bed and a method for recovering growth of underwater submerged plants. The submerged plant modularized growth bed comprises suspended solids, planting layers, plant layers, a growth substrate layer, a bearing layer and balance weight facilities, the submerged plant modularized growth beds are mutually connected to form an entire piece, micropores are formed in the bearing layer so that roots of the plants can penetrate through, the growth substrate layer adopts planting soil, the periphery of the planting layer is fixedly connected with the periphery of the bearing layer, the planting layers and the bearing layer wrap the growth substrate layer, the suspended solids are fixedly arranged around the submerged plant modularized growth bed, each suspended solid is hollow and is filled with air, and the balance weights are fixedly arranged at the lower end portion of the suspended solids to keep the depth of the modularized growth bed suspending on the water surface. The submerged plant modularized growth bed is reasonable in design, compact in structure, simple to manufacture, low in cost, simple to operate and convenient to manage, and the submerged plant modularized growth bed is degraded along with the growth of the underwater submerged plants, is free of pollution, protects the environment, is wide in application range, is widely popularized conveniently, and is favorable for recovery of the underwater submerged plants in different water areas.

Terrace pond construction method and terrace pond structure applicable to hydro-fluctuation belt water bay slope

The invention discloses a terrace pond construction method and a terrace pond structure applicable to a hydro-fluctuation belt water bay slope. The method mainly comprises the steps of (1) constructing a 'land-hydro-fluctuation belt-water body' foundation, (2) arranging a water collecting pond, (3) trimming a hydro-fluctuation belt or part of land into a terraced field along the slope, (4) planting floating plants, emergent aquatic plants, hygrophilous plants and damp tolerant plants along the terraced field from bottom to top, and culturing fishes in a water body area, wherein in the terrace pond structure, the slope is in a step structure, at least one water collecting pond is arranged on the step structure, a water sprayer and a water pipeline are arranged in the water collecting pond, a submersible pump is arranged in the water body area, and the water pipeline is arranged at the bottom of the water collecting pond and is communicated with the immersible pump; the height difference between every two adjacent ladders of the terrace field is 0.3-1.5m, and the width of the surface of each ladder is 1.5-15m. The terrace pond structure also has the functions of water-soil high-efficient utilization, non-point source pollution prevention and control and landscape, and is particularly applicable to the hydro-fluctuation belts at reservoirs, rivers or lakes where the bank has a certain slope and the water level variation amplitude is large.

Mesh networking method based on Bluetooth low energy and system thereof

The invention discloses a Mesh networking method based on Bluetooth low energy and a system thereof. The method includes the following steps: turning on a Bluetooth module of a main control device forscanning, and simultaneously enabling Bluetooth modules of all sub-devices to turn on the broadcast; when the Bluetooth module of the main control device scans two of the sub-devices, respectively responding to the Bluetooth modules of the sub-devices to establish data interaction, and separately defining the sub-devices as a left sub-node and a right sub-node of a network; enabling the Bluetoothmodule of the sub-device that is defined as the left sub-node or the right sub-node to turn off the broadcast and turn on scanning the remaining sub-devices, and connecting and defining a secondary left sub-node and a secondary right sub-node corresponding to the left sub-node or the right sub-node; and sequentially connecting and defining the sub-nodes corresponding to all sub-devices, and connecting all the sub-devices to the network to form a Bluetooth Mesh networking structure. According to the scheme of the application, the problem that an existing Bluetooth Mesh networking method complicates the topological structure of the network can be solved.
