Embodiment Construction

[0036] The present invention will be further described below in conjunction with specific examples.

[0037] Such as Figure 1~Figure 6 As shown, an indoor leaching and soaking device for simulating forest areas includes a water storage tank 1, a timing electric valve 2, a micro suction pump 3, a leaching soaking system, a leaching solution collecting device, and a syringe extractor 11. The water storage tank 1 is provided with a plurality of water outlet holes 4 at the bottom of the four sides, and each water outlet hole 4 is equipped with a rubber plug 19, which can be connected with a plurality of micro-suction pumps 3 with a hose 20 at the same time, so as to realize simultaneous showering of multiple tree species and multiple components. For soaking, the water storage tank 1 is preferably a plastic tank, the micro suction pump 3 is determined according to the flow rate and lift, and the hose 20 is preferably a PVC plastic hose; a timing electric valve 2 is arranged on eac...

Abstract

The invention discloses an indoor simulated forest eluviation and immersion device which comprises a water storage tank, a timing electric valve, a micro suction pump, an eluviation and immersion system, an eluviation liquid collection device and a cylinder extractor, wherein a plurality of water outlets are formed in the bottom of the water storage tank; the eluviation and immersion system comprises a sprayer, a hollow cylindrical tank, a liquid guide V-shaped groove, a porous cushion layer and a liquid diversion funnel; and the eluviation liquid collection device comprises a conical flask and an overflow tank. The indoor simulated forest eluviation and immersion device disclosed by the invention is capable of achieving the indoor simulated field forest eluviation and immersion effect and determining eluviation and immersion results of different components (such as tree leaves, branches, bark and fruits) of different trees (different tree-ages), and has the characteristics of being time-saving, high in simulation trueness, excellent in contrast effect and the like.

Description

technical field [0001] The invention belongs to the technical field of indoor simulation experiment devices, and relates to a device for indoor simulation of leaching and soaking in forest areas. Background technique [0002] South my country is rich in rainwater and forest resources, and water quality in forest areas often deteriorates. Most of the existing studies believe that the dissolved organic carbon and nutrients carried by the components of trees in forest areas are collected into surface runoff under the action of rainfall, and eventually enter the water bodies in forest areas to cause pollution. The amount of organic matter carried by different tree species and components of each tree itself and produced by leaching and soaking with rainfall is significantly different, and natural factors in the field are difficult to control. Therefore, indoor simulations are carried out to explore different tree species and different components (leaves, branches, bark, fruit) i...
