Abstract

The invention relates to a novel plunger-type field soil sampler, and is especially suitable for soil sampling for soil between adjacent crops in crop growth seasons; the plunger-type field soil sampler comprises two vertical rods marked with scales; a handle is fixedly connected with an upper end of each vertical rod; a cross rod is fixedly connected with a lower end of each vertical rod; a stainless steel iron cylinder with two end openings is fixed below the cross rod; the two vertical rods are sleeved by piston handles; a piston rod is fixed at a lower end of each piston handle, and passes through the cross rod; a piston cap is fixed at a lower end of the piston rod; the piston cap has a round-pie shape corresponding to the stainless steel iron cylinder; meanwhile a specially-produced double top thread can be fixed on the vertical rod randomly; during soil sampling, according to a fixed scale, a maximal soil sampling depth can be controlled above the piston handle; during soil discarding, according to a fixed scale, soil samples with different depths can be discarded below the piston handle. The invention can be used for soil sampling with different soil depths in field tests, and especially for soil sampling for soil between adjacent crops in crop growth seasons.

Description

technical field [0001] The invention belongs to a field soil sampling tool for agricultural scientific research, in particular to a novel plunger type field soil fetcher, which is especially suitable for taking soil between adjacent crops during the crop growing season. Background technique [0002] Most of the existing tools used for collecting soil samples in field experiments are traditional shovels and small shovels. This not only increases the workload for the collection of soil samples, but also causes damage to the soil plow layer, and also causes damage to the crop root system and surrounding soil during the crop growing season. [0003] In addition, in scientific research work, soil augers are often used to fetch soil from the field. Although soil at different depths can be easily taken up, and there are accurate scale marks, it will not cause damage to crop roots and surrounding soil. However, the soil obtained by soil drilling is not easy to get down, especially ...
