Volume measurement device for plant leaves, and measurement method for same

Abstract

The invention relates to a volume measurement device for plant leaves. The device comprises a diameter-adjustable imbedding groove, a measuring cylinder placed in the diameter-adjustable imbedding groove, an operation board and a water container, wherein a leaf stopping net, a buoy and a water guide pipe are disposed in the measuring cylinder; a water valve is disposed on the water guide pipe, andtail end is inserted into the water container; a battery groove with a built-in battery and an operation rod of the leaf stopping net are disposed on the back face of the operation board, and a display screen, a zero clearing key, a reading key, a computation key, a water adding key and a leaf stopping net operation key are disposed on the front face; one end of the operation rod of the leaf stopping net is connected to the leaf stopping net and the other end is connected to the leaf stopping net operation key; a battery cover is disposed on the battery groove; the buoy is connected to the reading key by a sensing line; the water adding key is connected to the water valve; and the battery is connected to the display screen, the zero cleaning key, the reading key, the computation key, thewater adding key, the leaf stopping net operation key, the water valve and the leaf stopping net operation rod by circuits. The invention also discloses a measurement method for the device. The devicedisclosed by the invention is carried easily; and measurement speed is quick.

Description

technical field [0001] The invention relates to a measuring device, in particular to a plant leaf volume measuring device and a measuring method thereof. Background technique [0002] Desert plants and alpine plants belong to plants adapted to extreme environments. Desert plants are mainly limited by water stress, and alpine plants are mainly limited by low temperature stress. Leaf is the photosynthetic organ of plants, and the morphological adaptation of leaves affects the carbon assimilation capacity and resource utilization efficiency of plants. [0003] The leaf shapes of plants in adversity are varied, such as: scale, cone, triangle, strip, linear, lanceolate, quadrilateral strip, oblong-shaped oblanceolate, short cylinder, etc.; some leaves degenerate, with The young shoots of the year, that is, the assimilative shoots, carry out photosynthesis. Therefore, the photosynthetic organs of plants under stress are divided into two categories: leaf-shaped and axial-shaped. ...

AI Technical Summary

Problems solved by technology

Therefore, the photosynthetic organs of plants under stress are divided into two categories: leaf-shaped and axial-shaped. Leaf-shaped is that the thickness of the leaf is much smaller than the length or width, which is sheet-like; axial-shaped is that the thickness is similar to the length or width, and cannot be distinguished.

The leaves of most adversity plants are succulent, and the leaf area is difficult to measure, and it cannot reflect the photosynthetic characteristics of plants well.
