Embodiment Construction

[0024] The integrated device for in-situ monitoring of farmland underground leaching and surface runoff of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] 1. Runoff pool construction

[0026] 1.1 Runoff pool

[0027] 1.1.1 Quantity and arrangement of runoff pools: Regardless of plain area or mountainous hilly area, each plot corresponds to a runoff pool, which is used to collect runoff water from the plot ( figure 2 , image 3 ). In order to quickly empty the accumulated water in the runoff pool and facilitate the cleaning of the runoff pool, a drainage pool ( figure 2 ). Slope cultivated land in mountainous and hilly areas does not need a drainage tank, and directly uses drainage grooves to drain water.

[0028] 1.1.2 Volume of runoff pool: The size of the runoff pool is determined by the capacity to accommodate the runoff produced by the largest single field rainstorm in the area. The siz...

Abstract

The present invention discloses a farmland underground eluviation and surface runoff monitoring integration device which belongs to the fields of environment science, agrology and plant nutrition. The device of the present invention comprises of runoff pool, eluviation disk, outlet pipe, sampling bottle and runoff collecting pipe; eluviation disk is mounted horizontally on the runoff pool at aim depth of upright soil section, sampling bottle is connected with water outlet of eluviation disk through outlet pipe to collect eluviation solution; runoff collecting pipe is a four-way pipe like a Chinese word 'Shang' containing one water outlet and three lockable infall with different high; each runoff pool is communicated with at least one water outlet of runoff collecting pipe. The present invention is particularly suitable for monitoring the affects of ground water of soil solute such as nitrogen, phosphor, pesticide and so on, specially under the condition of original monitoring, can monitor soil eluviation and runoff at the same time and the same position, the nicety is improved and the sampling process is easy and rapid.

Description

technical field [0001] The invention relates to an integrated device for in-situ monitoring of farmland underground leaching and surface runoff, which belongs to the research fields of environmental science, soil science and plant nutrition. The device is especially suitable for monitoring the impact of leaching of nitrogen, phosphorus, pesticides and other soil solutes on groundwater, especially under the condition of realizing in-situ monitoring, it can monitor soil leaching and runoff at the same time at the same time, which improves the accuracy. And the sampling process is simple and fast. Background technique [0002] Soil erosion, non-point source pollution, nutrient loss in agricultural and forestry land, and migration of pollutants and nutrients in the soil are serious problems facing my country's ecology, environment, and agriculture and forestry. Runoff and leaching are the initiators and main carriers of these processes. The pollution of groundwater by nitrogen ...
