Background
The compound soil is artificial soil prepared by scientifically preparing original soil or foreign soil, organic and inorganic improved materials and microbial inoculum. Bulk density is one of the important properties of the formulated soil. The current method for measuring the bulk density of the formulated soil is mainly to soak the soil in water by a single cutting ring and then dry the soil to measure the weight. In the process of soaking and water absorption of the formulated soil, the soil in the cutting ring can absorb water and sink, so that the cutting ring can not be filled with the water, and the actual change of the volume of the soil after the formulated soil is backfilled and watered can not be simulated. After the formulated soil is watered, the soil can sink, the height is reduced, and the volume is reduced. Soil pore space is reduced due to the fact that the volume of soil is reduced, measured volume weight is increased, and effective data cannot be obtained. The method solves the problem that the ring cutter is continuously added and compounded in the process of soaking and saturating. However, when the formulated soil in the cutting ring does not sink any more in the method, the soil is easy to fall into the soaking solution by adding the soil. After water absorption is completed, residual complex soil on the cutting ring is difficult to reasonably remove, the complex soil can fall into a soaking solution only by cutting with a knife, experimental data are influenced, meanwhile, waste of the complex soil can also be caused, and therefore the device for measuring the unit weight of the complex soil is provided for solving the problems.

The apparatus for determining bulk density of regolith as claimed in claim 1, wherein: be equipped with lug (201) on rotatory ring (2), be equipped with outer annular groove (104) on ring sword lid (1), lug (201) support and lean on in outer annular groove (104), ring sword lid (1) one end is equipped with internal thread (106), and ring sword (3) one end is equipped with external screw thread (301), and internal thread (106) and external screw thread (301) meshing.
10. The method for measuring bulk density of a compost as claimed in any of claims 1 to 9, comprising: s1, placing the cut filter paper (7) with the size slightly smaller than that of the annular knife cover with the hole at the bottom into a bottom cover (8) with the hole, and installing the bottom cover (8) at the bottom of the annular knife (3) for sealing;
s2, connecting the cutting ring cover (1) with the cutting ring (3) in a threaded manner, placing the cutting ring (3) into a container (9), and adding water into the container (9) to the upper edge of the cutting ring (3);
s3, driving the magnet (5) on the rotating ring (2) to rotate, and driving the third blade (403) to rotate by the magnet (5) so as to open the ring cutting mechanism (4);
s4, adding the formulated soil into the cutting ring (3), enabling the formulated soil to be 0-2cm lower than the upper edge of the cutting ring cover (1), enabling the formulated soil to absorb water for 4-12h until the soil is saturated, if the formulated soil sinks below the upper edge of the cutting ring (3) in the saturation process, continuing to add the formulated soil into the cutting ring (3) until the soil in the cutting ring (3) does not sink any more;
s5, rotating the magnet (5) on the rotating ring (2), and enabling the magnet (5) to drive the third blade (403) to be attached to the first blade (401) so as to enable the ring-cutting mechanism (4) to be folded;
s6, removing the cutting ring (3) out of the container (9), pouring water in the container (9), placing dry sand with the thickness of 2cm into the container, removing the cutting ring cover (1), separating the cutting ring cover (1) from the cutting ring (3) so as to remove the redundant coordinated soil on the upper edge of the cutting ring (3), and draining the device for 2-4 hours;
s7, placing the corrected cutting ring (3) into a 105 ℃ oven to be dried to constant weight, and calculating bulk density BD of the prepared soil by adopting the following formula;
BD=(（W-Wring (C)）)/V；
In the formula: w is the weight of the drying soil added to the lower cutting ring (3),w ringThe weight of the cutting ring (3) is shown, and V is the volume of the cutting ring (3).
