Problems solved by technology

This collector includes a seepage tube with a clay head at the bottom, a liquid collection bottle, a buffer tube, a negative pressure device, and a catheter. It can only collect a certain point of soil solution when collecting. When ions migrate vertically, multiple collectors are required, resulting in a significant increase in collection costs
Usually the length of the collector is long and cannot be adjusted according to the required depth, so the practicability and economy are greatly limited

Embodiment Construction

[0028] With reference to accompanying drawing, this soil solution layered continuous collection device comprises catheter 5, and one end of described catheter 5 radially passes through column wall 3 to be inserted in the cylinder that is made up of column wall 3 and column bottom 12 In the vertical soil column 15, the other end is connected with the layered liquid collection bottle 11 through the solenoid valve 7, the leather tube 8, and the leather tube interface 9.

[0029] The above-mentioned catheter tube 5 is connected with several water receiving trays 18 through connecting pipes 19 .

[0030] The above-mentioned liquid guide pipe 5, water receiving tray 18 and connecting pipe 19 are on the same horizontal soil layer section, and the water receiving tray 18 is evenly or non-uniformly distributed on a circle or multiple concentric circles.

[0031] A water receiving tray 1 is arranged above the column wall 3 so that the irrigation liquid is evenly sprinkled on the surface...

Abstract

The invention relates to a layered continuous collecting device for a soil solution, which comprises a drainage tube, wherein one end of the drainage tube radially penetrates through an upright column wall and is inserted and filled in a vertical soil column in a cylindrical body formed by an upright column wall and an upright column bottom; and the other end is connected with a layered liquid collecting bottle by a solenoid valve, a leather hose and a leather hose interface. The invention can reach the purpose of simultaneously and continuously collecting soil solutions of different soil layer depths in batch.

Description

technical field [0001] The invention relates to a device for layered and continuous collection of soil solution, in particular to a device for layered and continuous collection of potted soil solution or simulated original soil solution. The device is mainly used in the research of soil solution chemistry and plant rhizosphere chemistry in soil science, plant nutrition science and environmental science. It is widely used in soil and fertilizer research, soil pollution, water conservancy, environmental monitoring and other fields. Background technique [0002] Soil solution is the liquid phase part of the soil, which contains the leachate of various soluble substances in the soil, mainly including inorganic ions, organic ions and polymer ions and their salts. When people study the vertical migration of various ions in soil solution, according to different research purposes, it is necessary to collect soil solutions at different depths of soil to measure the content of target...
