Abstract

The invention relates to a soil cutting device for accurately obtaining non-rhizosphere soils at different distances from rhizosphere. A circular root box soil block tray device, a soil block locating lead screw device, a blade regulating device, an adjustable-speed motor switch and the like are arranged on a bracket, the bottom of a circular tray is connected with a rotating shaft of an adjustable-speed motor, anti-sliding soil block stop sheets are circumferentially uniformly distributed on the edge of the circular tray and fixed by soil block locating bolts; a first hand wheel in the soil block locating lead screw device and the upper end of a first lead screw are welded together; a second hand wheel in the blade regulating device and the upper end of a lead screw are welded together, the lead screw is matched with a thread on an auxiliary blade holding frame, the auxiliary blade holding frame is connected with a blade holding frame through a third lead screw, one end of the third lead screw and a third hand wheel are welded together, a blade is fixed on the blade holding frame; a first lead screw locating block in the soil block locating lead screw device is sleeved on the first lead screw and is connected with a bracket main cross beam bolt; the first lead screw is concentric with the rotating shaft of the adjustable-speed motor, and the blade regulating device is fixed on the lead screw.

Description

technical field [0001] The invention belongs to the technical field of plant non-rhizosphere soil research, and is used for studying the migration of nutrients in soil from non-rhizosphere to rhizosphere, and then absorbed and utilized by plants, involving the migration of nutrients in soil and the test of plant effectiveness. Soil cutting device. Specifically, it is a soil cutting device for accurately obtaining soil at different distances from the non-rhizosphere to the rhizosphere. The device is mainly used for experiments and research on soil nutrient migration, form transformation and nutrient availability, and can be widely used in fields such as soil fertility. Background technique [0002] The rhizosphere refers to the part of the micro-soil area that is different from the soil in physical, chemical and biological properties due to the influence of plant root activities. The scope of the rhizosphere is very small, generally within a few millimeters from the surface...
