Abstract
The utility model relates to a girdling bark cutter used for liquid flow observation of populus three trunks. The girdling bark cutter is composed of a handle, an annular blade and an axe-type blade, wherein the annular blade is arranged at the top of the handle, and the axe-type blade is arranged at the bottom of the handle. The blades are arranged at two ends of the girdling bark cutter, burden of working outdoors can be reduced, the girdling bark cutter is simple and labor saving in operation, efficiency of the liquid flow observation of the populus tree trunks can be effectively improved, and an indirect role can be played on keeping ecological balance can be achieved.
Description
Technical field
The utility model relates to cutter field, relates in particular to a kind of bark Girding cutter for the observation of diversiform-leaved poplar stem sap flow.
Background technology
Transpiration water consumption is important parameter in plant growth and ambient moisture research, wherein stem sap flow refers to the rising rising liquid stream causing in plant corpus, the mensuration of plant stem sap flow is for setting up significant (the department's Jian Hua of soilplant atmosphere continuum model, thermal pulse technology is measured stem sap flow progress [J], dirt band, 2007,29:475-481.), be also the key index of inquiring into regional moisture law of supply and demand, water saving measures etc.
Diversiform-leaved poplar (Populus euphratica) is seeds original, the most ancient in Populus, the unique arbor species of desert area of extreme drought, be distributed in north African, the Middle East and the riverbank of NORTHWEST CHINA arid biogeographic zone and the salt lick of low humidity, the important arbor species of NW China desert and Semi-desert Area, at present, only, in store large area forest land, the Desert Regions of China, concentrate the Ejina Banner that is distributed in Tarim Basin and Inner Mongol.By the research to diversiform-leaved poplar stem sap flow, can reflect the ecological characteristic under extreme drought environment, significant for protecting better local environment.
For the observation of diversiform-leaved poplar stem sap flow, first step is to peel diversiform-leaved poplar trunk exocuticle off.Be subject to the impact of environmental factor, diversiform-leaved poplar exocuticle becomes band polygon, while using general purpose tool peeling, usually monoblock epidermis can be torn, thereby the normal growth of diversiform-leaved poplar is caused to negative effect.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of bark Girding cutter for the observation of diversiform-leaved poplar stem sap flow of increasing work efficiency.
For addressing the above problem, a kind of bark Girding cutter for diversiform-leaved poplar stem sap flow observation described in the utility model, is characterized in that: it by hold handle and be located at described in hold the annular blade at handle top and be located at described in hold handle bottom axe type blade form.
Described annular blade is connected together and is formed by ring knife ridge upward and ring-type blade down; Described ring-type blade with described in hold handle top and join.
Described axe type blade is connected together and is formed by axe type cutter ridge and axe type blade; Described axe type cutter ridge with described in hold handle bottom connection.
Described axe type cutter ridge with described in hold handle bottom and be 120 ° of angles.
The thickness of described axe type blade is less than the thickness of described axe type cutter ridge.
The utility model compared with prior art has the following advantages:
1, due to annular blade cutter ridge in the utility model upward, blade down, therefore, ring knife ridge can press...with one's finger when operation, micro-processing is carried out in the diversiform-leaved poplar exocuticle position that uses axe type blade to get rid of, by holding handle and finger strength of adjustment, by impurity scraped clean outside xylem, until expose xylem.
2, because axe type blade in the utility model is thin, arete is wide, therefore, can divest fast diversiform-leaved poplar exocuticle, and can control peeling area, while avoiding other instrument peelings, monoblock bark is peeled off, increases work efficiency.
3, the utility model humanization designing, holding handle is connected with axe type blade and annular blade, all there is insert design at same utensil two ends, can reduce the burden of the operation of going out, simply laborsaving while operation simultaneously, can effectively improve the efficiency of diversiform-leaved poplar stem sap flow observation, and maintaining ecological balance is played to indirectly effect.
Brief description of the drawings
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure: 1-hold handle 2-annular blade 21-ring knife ridge 22-ring-type blade 3-axe type blade 31-axe type cutter ridge 32-axe type blade.
Embodiment
As shown in Figure 1, a kind of bark Girding cutter for diversiform-leaved poplar stem sap flow observation, it forms by holding handle 1 and being located to hold the annular blade 2 at handle 1 top and be located at the axe type blade 3 of holding handle 1 bottom.
Wherein:
Annular blade 2 is connected together and is formed by ring knife ridge 21 upward and ring-type blade 22 down; Ring-type blade 22 with hold handle 1 top and join.
Axe type blade 3 is connected together and is formed by axe type cutter ridge 31 and axe type blade 32; Axe type cutter ridge 31 with hold handle 1 bottom connection.Axe type cutter ridge 31 with hold handle 1 bottom and be 120 ° of angles.The thickness of axe type blade 32 is less than the thickness of axe type cutter ridge 31.
When operation, first ring-type blade 22 and axe type blade 32 are polished smooth sharply, be convenient to operation.Then grasp and hold handle 1 middle part, impact diversiform-leaved poplar exocuticle with axe type blade 32, separate according to observation area his-and-hers watches skin.Finally micro-processing is carried out in the position of getting rid of diversiform-leaved poplar exocuticle, the ring knife ridge 21 that press...withes one's finger, by finger strength of adjustment, by impurity scraped clean outside xylem, until expose xylem.
