The invention discloses a three-dimensional cultivation method for interplanting yew, pine and fern, which comprises the steps of site preparation, transplanting and interplanting, field management and the like. Select an altitude section of 1600-2500m, medium-thick soil with neutral to weak acidity, dig seedling plots, and apply base fertilizer. After raising the yew seedlings, soak the roots of the seedlings in the thin mud mixed with organic fertilizer, and then interplant them in a three-dimensional growth environment where the upper wood is pine and the surface plants are ferns, interplanting between every two rows of pine Two rows of yews, interplant a row of ferns between the two rows of yews. The row spacing of yew is 80~90cm, the row spacing of yew is 50~60cm, the row spacing between yew and pines is 100~120cm, and the row spacing of pine is 160~180cm. After the yew seedlings are transplanted and interplanted, weeding and soil cultivation are carried out 3 to 5 times a year, topdressing is done 2 to 3 times, and pine seedlings are topdressed once. Tests have proved that: according to the interplanting method of the present invention, the survival rate, growth rate and seed setting rate of the yew seedlings can be greatly improved, and the growth rate is fast and the fruit is early, which is suitable for popularizing and planting in a large area.

The invention discloses a composite damping board for the passenger car floor and a manufacturing method thereof. The composite damping board is formed by heating and pressing a bottom board, a damping sandwich board and a surface board; the damping sandwich board is made of recycled rubber and waste plastics. In the composite damping plate of the present invention, after the two outer surfaces of the sheet of the damping sandwich plate are impregnated with adhesive, they are placed between the bottom plate and the surface plate, heated on a hot press at 80-140°C, and pressed for 8- 16MPa, kept for 5-20 minutes made. The composite damping plate has a simple production process, less production equipment and low production cost, especially the use of waste rubber and plastics is beneficial to environmental protection and has good social benefits. The composite damping board has good sound insulation and shock absorption effects, and the average noise reduction index is 8-10dB(A), and can be widely used in passenger cars, trains, ships and occasions requiring sound insulation and shock absorption in buildings.

The invention relates to a road marking removal device provided with double milling wheels, belonging to the field of municipal tools. The road marking removal device concretely consists of a rack, afirst extension device, a second extension device, the first milling wheel, a first drive motor, a second drive motor, an absorption trough, a connecting rod, a fan, a storage box, a battery pack, drivers, wheels, an ultrasonic sensor, conduits, a controller, the second milling wheel, a first sliding groove and a second sliding groove. The road marking removal device provided with the double milling wheels has the beneficial effects that the device can remove road marking; the four wheels are separately driven, so that the road marking removal device can more conveniently turn or turn around;a differential mechanism is avoided being used, so that the road marking removal device is simple in structure and low in cost; trough absorbers are respectively arranged behind the milling wheels forcleaning and recovering the removed road marking; compared with the brush-cleaning type recovery way, the road marking removal device adopts the fan for absorbing to reduce dust amount, thus being easy to work in the city without affecting the municipal environment.

The invention discloses a hickory chick cultivation method, which comprises the following steps: (1) preparation of strains; (2) selection of multiplication sites and fungal materials: selecting woodlands with a certain slope and humus layer thickness as the multiplication The fungus materials are poplar wood, crop stalks and sawdust, and poplar wood is 0.5‑1.5m 3 , crop straw is 0.5‑2.5m 3 (3) planting: during early August-mid-October, according to the setting of one layer of fungus materials and one layer of strains, the stacks in the shape of a "pyramid" are piled up in turns in multiple layers, and the last covering soil is 2-3cm; The heap of the "pyramid" shape structure, the heap length × width × height is 1.2-1.5m × 0.8-1.2m × 0.4-0.6m, the heap spacing is 40-50cm, and the row spacing of the heap is 45-60cm; (4) Moisture management; (5) Picking: After the Morchella mushrooms in the coming year, the feet of the morels turn yellow and the ascus begin to unfold. The hickory chick cultivation method in the present invention can greatly reduce the consumption of poplar fungi while achieving stable production.

The invention provides a method for producing a foaming heat-preservation pipe. The method includes the steps that locating supporting beams are evenly fixed on the outer wall of an inner pipe body of the heat-preservation pipe in the radial direction; the inner pipe body with the locating supporting beams is sleeved with an outer pipe body with one closed end; the opening end of the outer pipe body is upwards and vertically fixed; liquid polyurethane is injected into a gap between the inner pipe body and the outer pipe body, the polyurethane foams and swells in the gap in a set time and at a set temperature, the gap between the inner pipe body and the outer pipe body is filled with the foamed polyurethane, and the foamed polyurethane is coagulated between the inner pipe body and the outer pipe body. The problem that an existing heat-preservation pipe is low in heat-preservation performance and high in maintaining cost is solved. In this way, accurate attachment between a polyurethane insulation coating and the inner pipe body and between the polyurethane insulation coating and the outer pipe body is guaranteed, moisture coagulation and internal corrosions are reduced, the service life of the heat-preservation pipe is accordingly prolonged, and the maintaining cost is accordingly reduced.

The invention discloses a roasting method of ladle in silicon smelting process. The roasting method comprises the following steps: S1. constructing a special tower body for roasting the ladle in a silicon smelting and pouring place, wherein the height of the tower body is 9.6 meters, the largest width bottom is 8.4 meters, the narrowest width of the upper end is 6.3 meters, three sides of the tower body are constructed, another side is hinged with an encapsulation plate, the top of the tower body is closed, two partition plates and four baffles are arranged, each partition plate is provided with a plurality of first openings at equal intervals, the width of each first opening is 175mm-265mm, the baffle is 3.6 meters high, and a plurality of second openings are formed in each baffle. The roasting method facilitates the cyclic utilization of energy resources, the sustainable development and green production can be realized, and the generation of waste gas and dust in combustion can be prevented from polluting the environment, so that the environment protection is facilitated, the roasting time is greatly shortened, the roasting speed is quickened, the roasting efficiency is efficiently improved, and the labor intensity of working staffs can be effectively lowered.

A hard disk ejecting device used in electronic equipment includes a frame body, a hard disk box, a blocking piece, a button and an elastic piece. The electronic equipment includes an upper casing, a lower casing and a side wall fixed between the upper casing and the lower casing, and the side wall is formed with an opening. The frame body is fixed on the lower case, and together with the upper case and the lower case, forms a receiving chamber which is connected with the opening. The receiving cavity is used for accommodating the hard disk box, and the hard disk box is used for accommodating the hard disk and is slidably connected with the frame body. The blocking part is fixed on the frame body and is located between the frame body and the opening, and blocks the hard disk box completely accommodated in the receiving chamber. The button is arranged on the electronic equipment and is connected with the blocking part. When the button is pressed, the blocking part is driven to move so that the blocking part is separated from the hard disk box. The elastic part is fixed on the frame body, and resists the hard disk box when the hard disk box is completely placed in the storage cavity, and pops the hard disk box out of the opening along the sliding part of the frame body when the retaining part is separated from the hard disk box.
