Abstract

The invention provides a device for verifying the straw decomposition efficiency of bacteria in a soil carbon cycle experiment, and belongs to the technical field of soil detection and treatment. Theverifying device comprises a cylinder body, an annular mounting seat, a soil dumping mechanism, a packaging bag fixing mechanism and a fixing claw position adjusting mechanism. By arranging the soil dumping mechanism, a main bearing plate plays a role in bearing a whole bag of soil, and an air cylinder drives the main bearing plate to ascend, so that the soil automatically slides into the cylinderbody from a packaging bag; by arranging the packaging bag fixing mechanism and the fixing claw position adjusting mechanism, the packaging bag can be tightly clamped on the main bearing plate, and the packaging bag is prevented from sliding into the cylinder body along with soil; and by additionally arranging supporting legs and rolling wheels, the auxiliary supporting effect on the main bearingplate can be achieved, the supporting legs are additionally arranged to be hinged to a third hinge seat and a second movable rod, the supporting legs and the rolling wheels can be stored in the direction of the cylinder body in the ascending and inclining process of the main bearing plate, and the lifting force of the air cylinder is reduced.

Description

technical field

[0001] The invention belongs to the technical field of soil detection and treatment, and specifically relates to a verification device for the decomposition efficiency of straw by bacteria in soil carbon cycle experiments. Background technique

[0002] my country's main food crops mainly refer to wheat and rice. After rice and wheat are harvested and threshed, the stems and leaves left behind are collectively called straw. Straw is rich in nitrogen, phosphorus and potassium. The traditional method is to leave the straw ash in the field by burning to provide nutrients for the next crop. However, burning straw produces a large amount of particulate matter that induces smog in autumn and winter, which is not conducive to environmental protection. The prior art proposes a bacterial degradation retting method, which not only does not pollute the environment, but also can retain nitrogen, phosphorus, potassium and other elements to the greatest extent, and thus h...
