Abstract

The invention relates to the technical field of soil infiltration capability measurement, and discloses a continuous measurement device and method for soil infiltration capability of a plough layer and a plough pan of an agricultural land. The device comprises a constant flow water supply device, a point source water distribution device for supplying water for a measured ground by point sources, an infiltration ring, a drain vessel, a camera and two flow sensors, wherein the constant flow water supply device is connected with the infiltration ring through a first water pipe, the infiltration ring and the drain vessel are connected through a second water pipe, the point source water distribution device is located in the infiltration ring, the two flow sensors are respectively located undera water outlet of the infiltration ring and under the drain vessel, and the camera is located over the infiltration ring. The device and the method are simple in operation and can save cost.

Description

technical field [0001] The invention relates to the technical field of soil infiltration performance measurement, in particular to a continuous measurement device and method for soil infiltration performance of plow layers and plow bottom layers of agricultural land. Background technique [0002] Focal plow farming is a farming method that is widely used at home and abroad and has a long history. After long-term farming activities, farmland soil will form a layered structure in the vertical direction: the surface soil has a high organic matter content, loose structure, and large pores; the soil at a certain depth below the surface is due to long-term plowing and compaction , forming a layer of soil layer that is relatively hard, denser in structure, and smaller in pores, which is usually called the plow layer. The soil under the plow bed is the undisturbed core soil. The plow bottom soil formed by conventional plow farming has a denser soil structure, larger bulk density, ...
