Fast blade transferring device used for accurately measuring fresh weight

Abstract

The invention relates to experimental facilities in plant physiology and ecology study, in particular to a fast blade transferring device used for accurately measuring fresh weight. The fast blade transferring device used for accurately measuring fresh weight comprises a pot body provided with an end cover and a handle, a filter-net-shaped interlayer is arranged on the inner wall of the pot body, and a gap is formed between the filter-net-shaped interlayer and the inner wall of the pot body; a hemisphere bracket is arranged in the pot body and hinged to the pot body through hinge shafts at the two sides, the hinge shaft at one side is provided with a twisting handle and a torsional spring, the hinge shaft at the other side is provided with a round piece bayonet, a clamping piece is embedded in the bayonet, a draw bar is connected to the upper portion of the clamping piece, an elastic piece is connected with the upper portion of the draw bar, and the connecting end of the elastic piece and the draw bar is hinged to the handle. The fast blade transferring device is reasonable in structure, easy to operate, economical and practical, prevents the external environment from affecting the water content of blades and accurately measures the fresh weight of the blades.

Description

technical field [0001] The invention relates to an experimental device in the study of plant physiology and ecology, in particular to a rapid blade transfer device for finely measuring fresh weight. Background technique [0002] The relative water content of leaves is one of the most commonly used indicators in the study of plant physiology and ecology, which can reflect the water state and physiological activity of leaves. The calculation formula of leaf relative water content is: relative water content=(fresh weight-dry weight) / (saturated fresh weight-dry weight). When measuring the relative water content of the leaves, usually a certain area of ​​leaves is cut from the whole leaves, and then weighed with a balance to obtain the fresh weight. [0003] As a tissue organ that contains water, the amount of water contained in the leaf will not remain constant, but will be affected by the external environment. One is that after the leaves are detached from the plant, the wate...

AI Technical Summary

Problems solved by technology

One is that after the leaves are detached from the plant, the water supply of the leaves will be quickly blocked, thus affecting the normal water state of the leaves; the other is that after the leaves are detached, due to the influence of the humidity of the external environment, the moisture of the leaves will continue to decrease. Volatilize to the outside, causing leaves to lose water

Therefore, in the process of measuring fresh weight, if the experimenter does not consider the influence of these two aspects, the measured fresh weight will be inaccurate, usually smaller than the normal value, thus affecting the accuracy of the calculation of relative water content of leaves
