Abstract
The invention relates to a multifunctional in situ soil and a soil solution collector, which comprises a 3 / 4metal knife cylinder with a T-shaped handle, a metal filter cap with 9 holes on hemisphere face bottom, 9 soft capillaries with porous polyester sample suction pipes at end part, an undertaking bottle, an air exhaust conduit and a hand-operated vacuum pump. Fitted screw threads are provided on an inner wall at the bottom of the knife cylinder and an outer wall on the top of the metal filter cap, and the connection is carried out. When sampling, the 3 / 4 metal knife cylinder is taken as a soil puncher for punching, the soft capillary with porous polyester sample suction pipes are arranged on the metal filter cap, and the assembled filter cap and sample suction pipe are fixed at the bottom of the knife cylinder and are placed in the soil. The collector has the advantages of convenient assembling, easy operation, utility and high efficiency, and can guarantee the high quality of the soil solution sample.
Description
technical field [0001] The invention relates to a multifunctional in-situ soil and soil solution collector, in particular to a multifunctional in-situ soil and soil solution collector capable of portable operation in the field. Background technique [0002] Soil solution is the aqueous solution containing various soluble substances leached from the soil, which is the liquid phase part of the soil. The composition of soil solution has certain rules, which reflect the history and characteristics of soil types, as well as seasonal dynamics and agricultural use. It is in close contact with the solid phase part and maintains a state of dynamic equilibrium with the solid phase surface. [0003] The detection of the environmental indicators of the wetland ecosystem often involves field sampling, and the environmental indicators of the soil solution are an essential part. The traditional soil solution extraction method is generally to collect soil samples in the field and bring th...
