Abstract
The present invention is open a kind of easy plant hydropenia testing agency mainly, comprise be sticked on plant stem and blade master pulse many groups for measuring the foil gauge of deformation and the strainmeter for receiving foil gauge data, often organize foil gauge directly to form to foil gauge and a tangential strain sheet by one, rectilinear direction directly to foil gauge along plant stem or blade master pulse is arranged, tangential strain sheet is arranged along the vertical direction of plant stem or blade master pulse, and the stem of plant and blade have one group of foil gauge respectively at least, described each foil gauge is connected with strainmeter respectively by connecting line.Plant hydropenia testing agency provided by the invention utilizes the change principle of resistance value, from the angle of plant, the current water cut of plant can be measured more accurately, judge that whether the current whether lack of water of plant, water cut be sufficient, and this testing agency's structure is simple, easy to operate, measure accurately, be suitable for applying.
Description
Technical field
The invention belongs to precision agriculture applied technical field, be specifically related to a kind of easy plant hydropenia testing agency.
Background technology
Water is the main constituent of plant, and the water cut of hydrophyte is the highest, can reach 98%; Herbal water cut is approximately 70% ~ 80%; The water cut of xylophyta will be lacked, and about 40% ~ 50%; What water cut was little is the plant living in desert area, only has 16%.Life is not had without water.Water is the solvent of a lot of material, after all necessary elder generation such as the mineral matter in soil, oxygen, carbon dioxide is water-soluble, just can be absorbed and used by plants.Water can also maintain the tensity of biological cells and tissues, plant organ is kept upright situation, is beneficial to normally carrying out of various metabolism.Water is that photosynthesis manufactures organic raw material, and it also participates in a lot of Biochemical processes in plant as reactant, and therefore the vital movement of water to plant seems particularly important.
Foreign Epidemic adopts DTR technology to carry out the water percentage of monitoring plant, and this technology not only cost is high, and needs to use DTR waveguide probe to insert in plant, causing certain injury, especially just not easily adopting when monitoring precious species plant.Domestic also some adopts and carrys out monitoring plant lack of water by measuring the characteristics such as plant resistance, electric capacity, also occurred that veggetable electricity impedance monitors by measuring recently, but they have employed probe to insert in plant.Creative design company Koubachi was proposed a special alarm in 2012---wireless lack of water sensor.Wireless lack of water sensor is inserted in earth, it can detect the edaphic condition of locality, floristics, and data are sent to existing iOS in home network by Wifi and apply, then application will tell that user should water, and spray or apply fertilizer suitable, and the calculating of these data has then all been come by wireless lack of water sensor.But lack of water sensor is positioned in soil, there are some to distinguish with the water cut of cauline leaf, well do not measure the current water cut of plant.
Summary of the invention
The object of the invention is the problem for the current water cut of plant can not be detected in prior art preferably, a kind of easy plant hydropenia testing agency is provided, this testing agency can measure the current water cut of plant more accurately, judges that whether the current whether lack of water of plant, water cut be sufficient.
The technical scheme that the present invention realizes above-mentioned purpose employing is: a kind of easy plant hydropenia testing agency, comprise be sticked on plant stem and blade master pulse many groups for measuring the foil gauge of deformation and the strainmeter for receiving foil gauge data, often organize foil gauge directly to form to foil gauge and a tangential strain sheet by one, rectilinear direction directly to foil gauge along plant stem or blade master pulse is arranged, tangential strain sheet is arranged along the vertical direction of plant stem or blade master pulse, and the stem of plant and blade have one group of foil gauge respectively at least, described each foil gauge is connected with strainmeter respectively by connecting line.
Beneficial effect of the present invention
Plant hydropenia testing agency provided by the invention utilizes the change principle of resistance value, from the angle of plant, the current water cut of plant can be measured more accurately, judge that whether the current whether lack of water of plant, water cut be sufficient, and this testing agency's structure is simple, easy to operate, measure accurately, be suitable for applying.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Reference numeral: 1, straight to foil gauge, 2, tangential strain sheet, 3, connecting line, 4, strainmeter.
Embodiment
As shown in the figure: a kind of easy plant hydropenia testing agency, comprise be sticked on plant stem and blade master pulse many groups for measuring the foil gauge of deformation and the strainmeter 4 for receiving foil gauge data, often organize foil gauge directly to form to foil gauge 1 and a tangential strain sheet 2 by one, rectilinear direction directly to foil gauge 1 along plant stem or blade master pulse is arranged, tangential strain sheet 2 is arranged along the vertical direction of plant stem or blade master pulse, and the stem of plant and blade have one group of foil gauge respectively at least, described each foil gauge is connected with strainmeter 4 respectively by connecting line 3.
Described foil gauge is resistor disc, and when foil gauge is attached on plant stem, during plant hydropenia, a little change can occur the diameter of stem, and now tangential strain sheet 2 is by the impact of diameter change, and its shape also changes; Meanwhile, also can there is the contraction of trace in plant epidermis, and be directly subject to the impact of length variations to foil gauge 1, its shape also changes; Foil gauge 1 shape changes, and causes resistance to change, the change of generation data corresponding on the strainmeter 4 that foil gauge connects, and illustrates that plant lacks more when the data variation on strainmeter 4 is larger.When foil gauge is attached on blade master pulse, during plant hydropenia can there is less change in the diameter of master pulse, then trace change occurs the shape of tangential strain sheet 2; And along with the minimizing of moisture on cauline leaf, cauline leaf produces downward displacement because of gravitational reason, produce less moment of torsion, then there is trace change in the straight shape to foil gauge 1, now strainmeter 4 can demonstrate certain numerical value according to the change of diameter and the generation of moment of torsion, we can different according to the difference of data on strainmeter 4 and foil gauge position, and whether lack of water, plant lack serious to tell plant.Plant hydropenia testing agency provided by the invention utilizes the change principle of resistance value, from the angle of plant, the current water cut of plant can be measured more accurately, judge that whether the current whether lack of water of plant, water cut be sufficient, and this testing agency's structure is simple, easy to operate, measure accurately, be suitable for applying.
Because plant is certainly in continuous growth, therefore foil gauge needs periodic replacement, is generally 4-7 days and changes once.
experimental data
Experimental subjects: the main rattan of cucumber and petiole master pulse
Record through test: be attached to the foil gauge on the main rattan of cucumber, when the main rattan water cut of cucumber is 55-90%, water cut often reduces by 10%, and the tangential strain sheet 2 be entangled on main rattan shrinks 0.15mm.
Be attached to the foil gauge above petiole master pulse, when petiole master pulse water cut is 55-90%, water cut often reduces by 10%, and to be directly stretched 0.33mm to foil gauge 1, tangential strain sheet 2 shrinks 0.11mm.
