Background

Soil, mainly comprising inorganic ions, organic ions and polymeric ions and their salts. The composition of the soil has certain rules, which reflect the history and characteristics of the soil type, and also reflect seasonal dynamics and agricultural conditions. The soil is an important component of soil subject research, directly reflects soil nutrient and moisture conditions, provides reference for determining soil nutrient supply conditions and growth conditions of crops, and is particularly prominent in rhizosphere dynamic research on the other hand. In the existing soil sampler, a hole is drilled by a soil drill before the soil sampler is inserted into soil during burying. However, when the soil is taken out, the soil with loose soil quality can easily fall down, and the soil with a certain depth can not be accurately collected. To this end we propose a soil sampler that prevents the underlying soil from falling.
