Problems solved by technology

[0005] The invention provides a soil sampling and moisture measuring device for drip irrigation test, which solves the time-consuming and labor-intensive testing method of soil moisture, which requires people to use the soil drill to take samples continuously, and the soil moisture will regenerate as time delays. The distribution process, which in a certain sense makes the data less representative and other issues

Abstract

The invention relates to an apparatus used for soil sampling and moisture measuring in drip irrigation tests. The apparatus comprises a positioning device, a sampling scale plate, a pushing device and a sampling drilling pipe; the pushing device comprises a threaded support rod; the bottom of the threaded support rod and a connecting rod are connected via a pushing device fixing hole; the top part of the threaded support rod is provided with a rocking handle; the threaded support rod is provided with a spring; the spring is arranged below a movable scale plate; the sampling drilling pipe is a hollow circular pipe provided with a side seam; the top part of the hollow circular pipe is provided with a hollow circular pipe threaded mouth; the end part of the hollow circular pipe is provided with a wedge-shaped head; and the circle center of an outer ring, the circle center of an inner ring, the center of the pushing device fixing hole, and the center of a pushing device installing hole are on a same line. The apparatus is capable of avoiding time consumption and labor consumption of sampling using existing single soil drills, and influences on test results, reducing test cost, and increasing test precision and work efficiency as far as possible.

Description

technical field [0001] The invention relates to a soil sampling and moisture measuring device for a drip irrigation test, which belongs to the field of farmland irrigation. Background technique [0002] Drip irrigation is a water-saving irrigation technology with great development potential. With the increasing shortage of agricultural water resources in our country, drip irrigation has broad application prospects in our country. Therefore, drip irrigation technology has always been a research hotspot in the field of irrigation and drainage. The mechanism of point source infiltration and the law of soil water and fertilizer migration are important contents of drip irrigation research. However, for drip irrigation point source infiltration tests, how to obtain soil moisture values ​​through reasonable technical means has always been a headache. [0003] At present, the soil moisture test mainly includes drying method, neutron meter, TDR soil moisture meter, TRIME time domain...
