Drill pipe for measuring soil depth

Abstract

The invention provides a drill pipe for measuring the soil depth. The drill pipe comprises a ruler rod, a drill bit, a handle, a screw and a nut. The ruler rod is provided with a drilling hole, the handle is composed of two same thin plates, round holes are formed in the thin plates, the thin plates are provided with two U-type grooves, scales are disposed on the ruler rod, and the drill bit is tapered. The drill pipe for measuring the soil depth is simple in structure, economical and practical, measuring is very convenient and efficient to achieve due to the arrangement of the drill bit and the handle, adjustment is convenient to achieve, and the scales on the drill rod enable a measurer to measure the soil depth in the first time.

Description

technical field [0001] The invention relates to a drill pipe for measuring soil depth. Background technique [0002] In the cultivation of flue-cured tobacco, deep plowing is usually used to plow the tobacco field before transplanting. Because deep plowing and deep plowing can adjust the potassium absorption by improving the root system stretching environment and water conditions, this is an important means to increase potassium. Deep pine Deep plowing has the following advantages: 1. Timely adjust the soil moisture, plow and ventilate, and promote the increase of biomass; improve soil structure, apply farmyard manure to increase biomass; promote soil nutrient mineralization; cover green manure with green manure, coordinate soil nutrition; The texture is sticky, the plow layer is shallow, and there are problems at the bottom of the plow. Through deep plowing, the plow layer can be deepened, the bottom of the plow can be broken, the problems of stagnant water and root system ...

AI Technical Summary

Problems solved by technology

The depth of deep loosening and deep plowing varies with different varieties of tobacco seedlings, so it is necessary to measure the depth of loose plowing. At present, most of them are measured by hand digging, which has low efficacy and requires a large labor force.
