The invention belongs to the technical field of colored steel tiles, and particularly relates to a composite colored steel tile. The composite colored steel tile comprises a colored steel tile body which is made of a composite material, the two ends of the sunken position of the colored steel tile body are fixedly connected with first baffles, and water storage tanks are formed by the first baffles and the sunken position of the colored steel tile body; a second baffle is arranged between the adjacent first baffles and slidably connected with the side face of the colored steel tile body through a sliding block; and the side, close to the colored steel tile body, of the second baffle is fixedly connected with a rack, a gear is arranged between the second baffle and the colored steel tile body, and the gear is rotatably connected with the colored steel tile body through a rotating shaft. The structure is simple, a closed cavity is formed through the first baffles, the second baffle, a piston plate and the sunken position of the colored steel tile body, evaporation losing of water in the cavity is reduced, the heat-insulation performance of the composite colored steel tile is improved, and the indoor temperature is effectively lowered.

The present invention discloses an irrigation system. It includes water source, level controller, water-distributing pipe with several water-distributing holes and quantity-limiting water-supplying disk. The water source is connected with level controller, the level controller is connected with water-distributing pipe, the water-distributing pipe and the quantity-limiting water-supplying disk areburied in soil, the quantity-limiting water-supplying disk is placed under the water-distributing pipe and is closed to the water-distributing pipe. Besides, said invention also provides the irrigation method by using said irrigation system.

The invention discloses an artificial soil structure for planting crops in lands unsuitable for growth such as the Gobi Desert or deserts. The artificial soil structure is characterized in that a groove is formed, a clay layer (2) is laid on a desert stratum (1) at the bottom of the groove, a charcoal and clay mixed layer (3) is laid on the clay layer (2), a mixed layer (4) of charcoal, clay and organic matter is laid on the charcoal and clay mixed layer (3), a grave layer (5) is laid on the mixed layer (4) of the charcoal, the clay and the organic matter, and the thickness of the grave layer (5) is smaller than ten centimeters. Artificial soil of the artificial soil structure has the abilities of water preservation and fertilizer preservation and can continuously provide water and fertilizer for the crops, the clay at the bottom layer can prevent moisture from infiltrating and being lost, a soil mixed layer of the charcoal and the clay or mineral rich in clay has the functions of preventing nutrient and moisture from infiltrating, and the soil containing the charcoal and the clay or the mineral rich in clay and an organic matter layer are a main body for growth of the roots of the crops and are the main body for providing water and fertilizer for growth of the crops.

The invention relates to the technical field of essence purification, and discloses an essence purification device containing various plant extracts, including a frame, the upper surface of the frame is fixedly connected with a retort, and one side of the retort is fixed There are two heating rings connected, one side of the distillation tank is provided with a feed inlet, one side of the feed inlet is fixedly connected with a feed hopper, and the inner wall of one side of the feed hopper is provided with two slides, and the slides are flexibly connected with Pushing plate, one side of pushing plate is fixedly connected with extension spring, the other end of extension spring is fixed with one side inner wall of feeding hopper, and one side of feeding hopper is provided with socket. The invention can add different materials at different time points for synchronous distillation, so that the extraction quality of plant essence is better, and at the same time, it can prevent the emission of plant essence gas, reduce the loss of plant essence gas, and at the same time protect the staff It also enables the staff to quickly discover the abnormalities that occur during distillation.

The invention provides a stereoscopic multi-functional liquid inoculation machine for artificial planting of Cistanche deserticola. The stereoscopic multi-functional liquid inoculation machine comprises a caterpillar tractor and a stereoscopic multi-functional liquid inoculation machine body installed behind the caterpillar tractor. The stereoscopic multi-functional liquid inoculation machine body comprises a gearbox, a seed-liquid stirring device, a spray-sowing device, a hydraulic lifting arm, a furrow plough, a truss, a two-way spiral soil winding device, a soil fixing baffle, a soil dividing and soil covering baffle and sliding rollers. According to the stereoscopic multi-functional liquid inoculation machine, a series of Cistanche deserticola planting work procedures of furrowing, soil feeding, stirring (seed dressing), stereoscopic sowing, fertilizing, spraying of a degradable mulching film and soil covering are mechanically completed; besides, Cistanche deserticola seeds are uniform in sowing depth and are uniformly sown to the host root system inoculation section (the side wall of an inoculation furrow host face) in a sprayed mode, a stereoscopic inoculation film face is formed, and the inoculation section is enlarged, so that the contact probability of seeds and host roots is increased. The stereoscopic multi-functional liquid inoculation machine breaks through the mode of artificial planting and small-scale mechanical planting, and is easy and convenient to use and especially suitable for the large-scale industry production of the Cistanche deserticola.
