Background technology
Lysimeter is a kind of instrument of measuring evaporation from land or evapotranspiration and soil water leakage amount and breakthrough rate.Along with the development of the day by day in short supply and soil physics related discipline of water resource, as the indispensable device of research soil water regime and Plant Water Consumption rule, the research and development of small-sized lysimeter receive much concern.At present, existing lysimeter mainly includes and surveys the large-scale lysimeter in hole and the small-sized lysimeter of Weighing type.Although the open ended soil body of large-scale lysimeter is larger, the interior physicochemical property of soil of container and the growthform of plant and natural conditions are consistent, its equipment cost is higher, floor area is larger, project scale is large, and irremovable, at any time installing/dismounting; Traditional small-sized Weighing Lysimeter, artificial weighing operation is very inconvenient, uses the attendant equipment of gravity sensor more, and system constructing cost is larger.And existing lysimeter do not have root division device, cannot meet root division irrigate or cultivation condition under study plant transpiration, evaporation from land and soil moisture distribute and migration rule.
Summary of the invention
In order to address the above problem, the utility model provides a kind of simple and easy root division drainage type steaming to ooze device.
A kind of simple and easy root division drainage type steams and oozes device and mainly comprise steaming and ooze bucket, root division dividing plate, support, leakage water collecting bucket and the keg that catchments; Described steaming is oozed bucket and is positioned over above support; Root division divider upright is installed on to steam the middle of oozing in bucket and steaming is oozed to bucket and is on average divided into two equal spaces, and root division dividing plate height oozes a barrel 5-6cm lower than steaming; Steaming is oozed bottom of the barrel root division plate both sides and is respectively provided with a rubber stopper with holes, on rubber stopper with holes, is inserted with glass tube, on described rubber stopper with holes, is covered with filter screen; Steaming is oozed a bucket bucket wall and is provided with the gaging hole of measuring eight groups of soil moisture contents, and each district has four groups, and every group of gaging hole is three holes, every group of gaging hole in vertical direction be spaced apart 10cm; Leakage water collecting bucket is placed in below support, and leakage water collecting bucket is closed container, which is provided with the keg that catchments, water inlet pipe, snorkel and drinking-water pipe, and drinking-water pipe one end is inserted into the bottom of the keg that catchments; The water inlet pipe of plastic hose one end connection leakage water collecting bucket, the other end connects steaming and oozes the glass tube of bucket, thereby steaming is oozed to bucket and the connection of leakage water collecting bucket, plays the effect of collecting percolating water; Percolating water is extracted out with the percolating water gathering barrel from the keg that catchments with little water pump.
For pressure inside and outside balance leakage water collecting bucket, realize natural leakage effect, leakage water collecting bucket is connected with snorkel.
For steaming, Measurement accuracy oozes a barrel interior soil moisture content, verify distribution and the migration rule of moisture in the soil body, two partial root zones, steam respectively and ooze on barrel wall the hand of spiral at a certain distance and stamp soil moisture content gaging hole, one group of gaging hole is three holes, corresponding with three probe size of soil nmoisture content analyser (WET).
The water delivering orifice that bucket is oozed in steaming has filter screen, and percolating water is had to certain filtration, guarantees that percolating water circulation is smooth simultaneously.
The utlity model has following advantage:
Production process is simple, and cost is lower; Not only can measure evapotranspiration and the leakage of the general crop root soil body, also can measure accurately and quickly the soil moisture content of the different rhizosphere soil layers of crop, thus the vertical distribution situation of clear and definite moisture in soil; This steaming is oozed device and is had advantages of easy split and assembling, install simple, can recycled for multiple times, measurement result is accurate, with a high credibility.
Accompanying drawing explanation
Accompanying drawing 1 is structural drawing of the present utility model.
In figure: 1, steam and ooze bucket, 2, root division dividing plate, 3, soil moisture content gaging hole, 4, support, 5, filter screen, 6, rubber stopper with holes, 7, glass tube, 8, plastic hose, 9, glass three-way pipe, 10, connector, 11, water inlet pipe, 12, leakage water collecting bucket, 13, snorkel, 14, drinking-water pipe, 15, keg catchments.
Embodiment
The invention discloses a kind of simple and easy root division Drainage lysimeter, as shown in drawings, this lysimeter basic structure is oozed bucket 1, root division dividing plate 2, support 4 and leakage water collecting bucket 12 etc. by steaming and is formed.This device can be placed in the horticultural facilities such as heliogreenhouse or in laboratory, steaming is oozed to bucket 1 to be placed on support 4, leakage water collecting bucket 12 is placed under support 4, steaming is oozed to bucket 1 and be connected with water inlet pipe 11 by connector 10 with leakage water collecting bucket 12 use glass tubes 7, plastic hose 8, glass three-way pipe 9.Airtight leakage water collecting bucket 12 is provided with water inlet pipe 11, drinking-water pipe 14 and snorkel 13.
According to territory, most of crop root areal concentration, generally in 10-40cm topsoil, the present embodiment is set to steam and is oozed a bucket 1 high 50cm, in order to facilitate root division to plant, and the low 5cm of root division dividing plate 2 container end suitable for reading, and steaming is oozed to bucket 1 be divided into two equal spaces.
During concrete enforcement, first in steaming, ooze the sizeable filter screen 5 of bucket 1 bottom layer overlay, and spread the sand of thick layer 4-5cm thereon, to prevent that soil particle from flowing out and affecting measurement effect or stop up water stream channel with water, then the undisturbed soil of selected observation station is placed in steam and oozes bucket 1, and require root division dividing plate 2 both sides edaphic conditions consistent, and the root system of plant is on average separately planted on root division dividing plate 2, the steaming that root system is evenly distributed in root division dividing plate 2 both sides is oozed in bucket 1.In order to study the relation of moisture at soilplant atmosphere continuum, the present invention must adopt and quantitatively pour water, this just require this steaming ooze device should be placed in horticultural facility or laboratory in, therefore in the situation that irrigation quantity is certain, by weighing, add up the soil percolation water yield of extracting out, can obtain the evapotranspiration of overground part.Also the end sealing suitable for reading that steaming can be oozed to bucket 1, prevents soil evaporation, thereby obtains the transpiration rate of plant, so just can calculate whereabouts and the allocation proportion thereof of irrigation water.Steaming is oozed bucket 1 and is had 8 groups of soil moisture content gaging holes 3, each district has 4 groups, in vertical direction every mono-group of 10cm, in order to prevent that soil moisture content gaging hole moisture loss from affecting measurement result, after each measurement by its sealing, utilize the soil moisture content gaging hole 3 that soil nmoisture content analyser (WET) oozes on bucket 1 wall by steaming can measure the soil moisture content of the different soil degree of depth any time, can learn accordingly moisture distribution and the migration rule of soil.
