Description
Technical field the present invention relates to belong to the lysimeter that is used to observe plant transpiration water consumption and vegetation evapotranspiration in farming, forestry plant physiology, the ecological monitoring technical field, specifically a kind of full automatic underground water constant level compensating evaporimeter-lysimeter.
Background technology plant transpiration water consumption and vegetation evapotranspiration are important index in plant physiology ecology, water-saving irrigation and the agriculture and forestry engineering design.Though it is a lot of to measure the method for plant transpiration amount and vegetation evapotranspiration at present, can not measure and grasp water consumption and the water consumption rule of trees complete stool exactly.
The traditional plant evapotranspiration and the assay method of rising intensity are a lot, can divide sprig rapid weighing method, the rising mensuration of various leaves chamber method blade system, microclimate method, thermal diffusion method etc., these methods all are to measure the rising intensity or the liquid-flow state of the single organ of plant or organ a part, thereby calculate the transpiration rate of plant, the resultant error of reckoning is very big.
Lysimeter claims infiltrometer and soil seepage gauge again, the lysimeter method is accurately to measure the reliable method of plant complete stool evapotranspiration. the lysimeter kind is a lot, can branch Weighing Lysimeter and non-Weighing Lysimeter. Weighing Lysimeter can be used on farmland, grassland and forest, but can't be applied to the desert area that terrestrial materials often is in flow state.Existing non-Weighing Lysimeter is difficult to satisfy long location observation research owing to can not realize automatic water-supply and record.
Though the lysimeter of present domestic introduction or development voluntarily has large-scale Weighing Lysimeter, suspension Weighing Lysimeter etc. can accurately disclose the dynamic rule of individual trees and even association transpiration water consumption, but except that above defective, and because of costing an arm and a leg, the operating cost height is difficult to popularization and application.
Summary of the invention the purpose of this invention is to provide the full automatic underground water constant level compensating evaporimeter-lysimeter that a kind of cost is low, simple in structure, easy to use, measurement is highly sensitive.It is a kind of non-weighing formula lysimeter, can realize the constant control of underground water table, automatic water supplement, whole-process automatic collection and storage data, and can realize the computing machine immediately monitoring, satisfies the requirement of long-term position monitor.
Above-mentioned purpose is achieved through the following technical solutions: a kind of full automatic underground water constant level compensating evaporimeter-lysimeter, form by cultivating pool, water level control and make-up system, data handling system; Water level control and make-up system are made up of water tank, water level control pipe, water level control box, water layer separator tube, enlargement bubble box and cross over pipe; The water level control pipe upper end is contained in the water tank lower end, the water level control pipe lower end is positioned at water level control box and mutually concordant with the control water level face, water layer separator tube upper end is positioned at water level control box bottom, control water level face below, the water delivering orifice that water level control box is stretched out in water layer separator tube bottom is positioned at airtight enlargement bubble box, and water level control box is provided with the air admission hole that is communicated with atmosphere; Data handling system is made up of tipper counter, data collecting instrument and data acquisition line; Tipper counter is installed in the enlargement bubble box, and water layer separator tube water delivering orifice is corresponding with the quantitative tipping bucket position of tipper counter, and the data acquisition line is connected tipper counter with data collecting instrument; Cross over pipe is connected the enlargement bubble box water layer with the cultivating pool water layer.
Cultivating pool is arranged on not the seeping water of below ground, watertight large-scale pond body, at the bottom of the pond gravel bed is housed so that underground water table is set, top dress cultivating soil.Cultivating pool underground water table SW is set in the cultivating pool bottom
PlantSet control water level SW in the water level control box
Control, the enlargement bubble box inner bottom part forms a bubble water level SW
Swollen, control water level SW
ControlEqual cultivating pool underground water table SW with the water layer difference in height h of interruption-forming under the water layer separator tube
PlantHeight of water level difference H with the formation of enlargement bubble box inner bottom part bubble water level.The place establishes freeing port in the cultivating pool underground water table.Enlargement bubble box of the present invention is equivalent to be provided with on the link road of water level control box and cultivating pool water table and expands bubble, and the bubble that expands separates water layer, and tipper counter is installed in the enlargement bubble box, has created the working environment of automatic metering system.The critical component that separates water layer formation bubble is the water layer separator tube.
The present invention relies on air pressure to realize that the underground water table of automatic water supplement and control water level, tipping bucket metering keeps constant compensation lysimeter.When plant transpiration or the evaporation of native face, cultivating pool soil moisture wanes, upwards conduction of moisture under the capillary force effect, cultivating pool underground water table SW
PlantDescend and cause bubble bottom decline of water table, cause pressure in bubbles to lower, the water of water level control box replenishes downwards with the water droplet form along the water layer separator tube, at this moment control water level SW
ControlDescend, water level control pipe breaks away from control water level SW
Control, the water of reserve tank replenishes downwards along water level control pipe, simultaneously airborne gas along water level control pipe to the water storing tank make-up gas.The water droplet that the water layer separator tube moves downward enters the water yield of tipper counter stoichiometric consumption, and the data that the First Astronautic Research Institute for Measurement and Test gets store data collecting instrument into by data line.
The present invention has realized constant control of underground water table and automatic water supplement, and cost is low, and applied range is saved manpower.Because of data handling system being installed as the automatic measuring apparatus of gathering, realized whole-process automatic collection and storage data, the data of being gathered are in time, accurately, reliably, and are highly sensitive, measure sensitivity and can reach 12.56g (depending on tipper counter).And can realize the computing machine immediately monitoring, satisfy the requirement of long-term position monitor.
