用于测定完整叶片光合速率的叶室,是根据各种植物叶片的大小和形状的不同制成。由于叶室大小是固定的,因此对一些叶片较大或较小的植物就无法使用。据此,我们设计研制了一种能开合活动的夹片叶室,效果很好,对用红外线气体仪等仪器分析也适用。其构造的特点如下:1.活动叶室由上下盖板组成,在文具铁夹的杠杆作用下,可上下自由开合,将叶片夹在中间进行采样测定(图1)。2.叶室不受叶面积大小和形状限制,对较大的
The leaf chamber used to determine the photosynthetic rate of an intact leaf is made according to the size and shape of the leaves of the various plants. Because the leaf chamber is fixed in size, plants that are larger or smaller than some can not be used. Based on this, we designed and developed a clip leaf chamber that can be opened and closed with good effect. It is also applicable to the analysis of instruments such as infrared gas meters. Its structure features are as follows: 1. Activities of the leaf chamber from the upper and lower cover plate, in the stationery iron folder lever, up and down freely open and close the leaves in the middle of the sample determination (Figure 1). Leaf chamber is not subject to the size and shape of the leaf area, the larger
