Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with specific examples, but not as a limitation of the present invention.

[0034] A method for linearly collecting soil samples according to an embodiment of the present invention comprises the following steps:

[0035] The first step is to prepare the earth taking device;

[0036] The second step is to determine the soil borrowing route;

[0037] The third step is to arrange a number of soil sampling points; the number of soil sampling points is determined by the area of ​​the plot and the density of soil sample collection;

[0038] In the fourth step, at each soil sampling point, first determine the sampling line on the soil surface, and then collect a soil sample of a profile downwards according to the sampling line to obtain the soil sample at the soil sampling point; the sampling line is perpendicular to the crop row straight line. The thickness of the section is 50 mm, and the depth...

Abstract

The invention discloses a soil sample linearly collecting method and a soil sampling device. The method includes preparing the soil sampling device; determining a soil sampling route; arranging a plurality of soil sampling positions; determining a sampling route on the soil surface at each of the soil sampling positions, and then collecting downward a soil sample of a section according to the sampling route to obtain a soil sample of each of the soil sampling positions; and mixing uniformly the soil samples of the soil sampling positions to obtain a soil sample of the whole farmland. The soil sampling device used for linearly collecting the soil samples comprises a soil sampling shell and a soil sampling head, wherein the soil sampling shell comprises a soil outlet disposed at a side of the soil sampling shell and moving wheels disposed at the bottom of the soil sampling shell, and the soil sampling head is disposed in the soil sampling shell. Because of difference of soil characteristics between crop rows and difference of soil characteristics at different distances in the crop rows, soil sampling methods at present have a disadvantage of bad soil sample representativeness. The method and the soil sampling device provided by the invention effectively solve the problem of the bad soil sample representativeness, and provide soil samples with high representativeness for detection of various soil indicators.

Description

technical field [0001] The invention relates to the technical field of collecting soil samples, in particular to a method for linearly collecting soil samples and a soil fetching device for linearly collecting soil samples, so as to realize collecting representative soil samples from farmland. Background technique [0002] In the prior art, in order to know various physical and chemical characteristics of soil, soil samples need to be collected, especially for the demand of precise fertilization and precision irrigation in farmland, more representative soil samples are needed. The objective situation is that it is impossible to take out all the soil layers of the farmland, mix the soil and then sample, so it can only be sampled at fixed points. When sampling farmland in the prior art, several sampling points are arranged along a certain route (such as "S" shape or "Z" shape, etc.) Column, the diameter of the soil column is 5-10 cm, and the soil at all sampling points is mix...
