Fig. 2 is rain cover synoptic diagram among the utility model one embodiment.
Embodiment
Regard to a kind of individual plant dungarunga canopy that the utility model proposes down and hold back measurement mechanism, describe in detail in conjunction with the accompanying drawings and embodiments.
As shown in Figure 1, the utility model provides a kind of individual plant dungarunga canopy to hold back measurement mechanism, includes: flowerpot 1, platform balance 2 and the rain cover 3 of planting dungarunga; Described flowerpot 1 of planting dungarunga places on the described platform balance 2, is provided with described rain cover 3 around described platform balance 2 and the flowerpot 1.
Preferably, the upper surface of described rain cover 3 is the inclined-plane, and reducing overstocked rainwater to the pressure of rain cover 3, and this upper surface is provided with the opening 4 that passes through for described dungarunga stem.
The range of described platform balance 2 and precision must satisfy the weight of dungarunga; The size of described rain cover 3 should be bigger, and it can not touch platform balance 2 and flowerpot 1, prevents that pressure is delivered to platform balance 2, influences measurement data;
Preferably, as shown in Figure 2, the longitudinal section of described rain cover 3 is right-angled trapezium, the last bottom side length of described right-angled trapezium greater than the height of the table top 202 of platform balance 2 and flowerpot 1 height and, the height of the length of side less than the support column 201 of described platform balance 2 of going to the bottom of described right-angled trapezium.
Preferably, the upper surface area of described rain cover 3 is greater than the area of the table top 202 of described platform balance 2.
Preferably, the upper surface of described rain cover 3 is provided with the opening 4 that passes through for described dungarunga stem, and the width of this opening 4 is decided according to the diameter of described dungarunga stem.
Preferably, the upper surface open 4 of described rain cover 3 is sealing described dungarunga stem by the back; Can adopt plastic cement to bring upper surface open 4 after protection dungarunga stem passes through, prevent that rainwater from entering.
Described rain cover 3 is the iron sheet groove.
Be example with the utility model one embodiment below, set forth its principle of work: measure the thickness of dungarunga canopy earlier, and according to this thickness described canopy is divided into multilayer; Second step was measured the dependency structure parameter of dungarunga canopy again, comprise that leaf area index, canopy branches and leaves wettability, canopy thickness and the canopy vertical plane of measuring canopy are long-pending, the flowerpot 1 of planting dungarunga is placed on the platform balance 2 of unlatching, and around described platform balance 2 and flowerpot 1, rain cover 3 is set; Described rain cover 3 can not contact with platform balance 2 and flowerpot 1, protects the opening 4 of the rain cover 3 that stem passes then with plastic adhesive tape, in case rainwater enters, checks that electric wire connects and platform balance 2 readings of opening is made zero (back of making zero shows that reading is clean interception); The 3rd step, the beginning rainfall, the reading of platform balance 2 is recorded at the interval at preset timed intervals; In the 4th step, stop rainfall, and measure the branches and leaves wettability of described canopy; When the described canopy branches and leaves wettability after the rainfall is identical with canopy branches and leaves wettability before the rainfall, cut the bottom of described canopy, and returned for second step and continue to carry out, carry out so repeatedly to the top layer of canopy; In the 5th step, according to the reading of the platform balance 2 that records, calculate the interception of every layer of described dungarunga canopy.
Adopt order from top to bottom that described dungarunga canopy is carried out beta pruning successively in the present embodiment, if adopt order from top to bottom, the input raininess was inconsistent when then each layer of canopy imported raininess and do not had beta pruning after the beta pruning, can not extrapolate the interception of each layer of canopy.
The utility model is held back measurement mechanism and method by a kind of individual plant dungarunga canopy is provided, the moisture that can more accurate, directly, dynamically study different crown structures and canopy layering cuts the amount of holding and transmission rule, promotes the research of the canopy hydrology mechanism of action; The utility model can also draw the variation of canopy interception in the minimum period according to experimenter's needs, and is time saving and energy saving; Simultaneously, in view of the mobility of potted plant nursery stock, the utility model all is suitable for outdoor and indoor.
