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.

The invention discloses a method for planting shiitake mushrooms in a large bed. The method comprises the following steps of 1, preparing a basic material of the large bed, wherein the basic material is prepared from 80-120 parts of sawdust, 10-20 parts of bagasse, 5-10 parts of corn cob particles, 20-30 parts of fungi residue powder, 5-10 parts of rice husk charcoal and 2-10 parts of assistant materials; 2, conducting high-temperature sterilization and cooling on the basic material of the large bed; 3, selecting a ventilated place facing the sun to build a mushroom shed, and building the large bed of the shiitake mushrooms; 4, selecting a cloudy day to inoculate shiitake mushroom strains into the basic material of the large bed, and covering the whole large bed of the shiitake mushrooms with thin film after the inoculation is completed; 5, waiting for spawn running of the shiitake mushrooms after the inoculation is completed, wherein the temperature at the spawn running period is kept at 20-25 DEG C, and the humidity is 70-80%, and uncovering the film for ventilation every night. Through the adoption of the method for planting the shiitake mushrooms in the large bed, unified management can be conveniently conducted on inoculation and fruiting of the shiitake mushrooms, the planting process can be simplified, and the labor cost is reduced.

The invention provides a planting circulation method for improving the oxygen absorption effect of plant roots through gas culture. A mounting frame is included, a water tank is arranged at the bottom of the mounting frame, the water tank is connected with a water pump, the water pump is connected with a water source, a water constant-temperature system is arranged in the water tank, a water outlet and a water inlet are formed in the water tank, and the water outlet is connected with in-and-out openings in the bottoms of planting devices; a light supplementing lamp is arranged on the top of the mounting frame, and the included angle between the center line of the light supplementing lamp and the horizontal line is 0-90 degrees. The planting devices are distributed on the mounting frame in a stepped mode; pipelines are arranged between the water outlet and the in-and-out openings of the planting devices. The method has the advantages that the space is efficiently utilized, illumination is controllable, the temperature is adjustable, independent heating is not needed, the ventilation amount of the plant roots is greatly increased, 90% of soil-borne diseases (anaerobic bacteria) can be eliminated, root respiration is enhanced, the growth speed of plants is greatly increased, the oxygen environment of the roots is improved, and the anaerobic type diseases cannot exist.

The invention provides a movable micro electrolysis wetland sewage treatment method and a movable micro electrolysis wetland sewage treatment system. The system comprises a pretreatment unit (1), a down-flow enhanced wetland region (2) in which a graphite particle anode electrolytic tank (18) is arranged, an electrolysis enhanced dephosphorization region (3) provided with a scrap iron anode electrolytic tank (19), and an up-flow denitrification enhanced wetland region (4) designed with a scrap iron anode electrolytic tank (20), which are used for removing suspended solids, organic matters / ammonia nitrogen, phosphides and nitric nitrogen respectively, wherein the electrolytic tanks are independent push-pull draw boxes, and are connected with a low-voltage stabilized voltage supply (14); a light fiber ball filter material is taken as a wetland bed filler. The system is provided with movable rollers (11). The invention develops a set of sewage treatment method and system which have the advantages of easiness, convenience, practicability, high efficiency, economical efficiency, beautifying of the environment and scattered on-site treatment aiming at the characteristics of economic backwardness, scattered distribution of sewage sources and the like of rural areas.
