The invention discloses a three-dimensional composite interplanting method for interplanting poria cocos and peanuts. The three-dimensional composite interplanting method comprises the following steps: S1, soil preparation; s2, applying a composite soil conditioner and building furrows; s3, putting the poria cocos into a cellar; s4, peanut sowing; s5, field management in the symbiotic period; s6, harvesting in a staggered manner. According to the method, the poria cocos is planted underground, the peanuts are planted on the ground, after the peanuts are harvested, the ground surface is covered with peanut straw, the poria cocos is shaded, the physical properties of soil are improved by returning the peanut straw to the field, two kinds of medicines and grains are planted in one field through poria cocos and peanut interplanting, and the land utilization rate is increased; meanwhile, the composite soil conditioner prepared by a specific method is applied, long-acting and synergistic biological stimulation is provided for the two crops, the soil permeability is improved, and special pretreatment is performed on pine sections, so that the poria cocos inoculation rate, stress resistance and yield of poria cocos strains are remarkably improved, the soil micro-ecological environment is improved, the soil permeability and enzyme activity are improved, and the yield of the poria cocos strains is increased. And double improvement of economic benefits and ecological benefits is realized.

The utility model discloses environment-friendly low-carbon rainwater collection equipment, and relates to the technical field of rainwater collection. The device comprises a collecting box, a conical collecting box is arranged in the center of the upper portion of the collecting box, a water inlet is formed in the center of the top end of the collecting box, an annular plate is fixedly connected to the position, close to the bottom, of the outer ring of the conical collecting box, and an annular cover is fixedly connected to the outer ring of the annular plate. An adapter pipe is fixedly connected to the center of the bottom end of the conical collecting box, the adapter pipe and the water inlet are located on the same horizontal plane, a sealing plate is arranged in the collecting box and located on the same horizontal plane with the water inlet, and the sealing plate is matched with the water inlet; according to the utility model, the conical collecting box is arranged, and the annular plate, the annular cover and the adapter are matched with one another, so that the problems that the workload is increased and the operation is relatively tedious because each position on the filter plate needs to be cleaned in sequence when branches on the filter plate are cleaned manually are solved.

The invention discloses a low-temperature cooking device and method of a multi-stage pressure coupling system. The device comprises a steam generation box, a stewing box and an electrical box. A steam generator is arranged in the steam generation box and used for generating hot steam. The stewing box comprises a box door and a box body, and a stewing container containing materials is placed in the box body; an air inlet and an air outlet are formed in the box body, an air outlet of the steam generator is communicated with the air inlet in the box body through a pipeline, and hot steam generated by the steam generator flows into the box body and is used for heating the stewing box; a temperature control system for controlling the temperature in the stewing box is arranged in the electrical box, a touch screen capable of displaying the temperature and pressure in the stewing box in real time is arranged on the electrical box, and different materials placed in the stewing container are processed by selecting corresponding temperature, pressure and time through the touch screen; after processing, the original taste and flavor of the materials and the fragrance of seasoning spices can be reserved, the taste level is richer, and part of material components are changed.
