Rapid leaf transfer device for precise fresh weight determination

Abstract

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. A quick blade transfer device for accurate fresh weight measurement, comprising a tank body, the tank body is provided with an end cover and a handle, the inner wall of the tank is provided with a filter mesh-shaped interlayer, and the gap between the filter mesh-shaped interlayer and the inner wall of the tank is There is a gap; the tank body is provided with a hemispherical bracket, and the hemispherical bracket is hinged with the tank body through the hinge shafts on both sides. There is a disc bayonet, and a card is embedded in the bayonet. The upper part of the card is connected to the drawbar. The upper part of the drawbar is connected to a shrapnel, and the connecting end of the shrapnel and the drawbar is hinged with the handle. The invention has a reasonable structure, makes the invention easy to operate, prevents the influence of the external environment on the water content of the leaves, and accurately measures the fresh weight of the leaves.

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 formula for calculating relative water content of leaves 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, th...

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
