The best manifestation of plant water status is represented by water potential, which can also reflect the plant's demand for water to a certain extent. When the water potential of the plant tissue is low, it is the demand for water that is fed back to us. Therefore, in agricultural production, the use of changes in plant tissue water potential to guide irrigation is very effective. For the detection of plant water potential, we recommend an instrument - plant water pressure chamber. The instrument is also the main equipment for the study of crop irrigation water, but many users do not understand the principle and use of the plant water potential pressure chamber. This article gives you a brief introduction.
The principle of the plant water potential pressure chamber is described as follows. The plant leaves or branches are clamped in the sample chamber, and the pressure at the first droplet of tissue fluid is observed by the pressure of the gas. The pressure at this time is the water potential of the plant-like tissue. The plant water potential pressure chamber can be used to measure the water potential of whole areas, different crops, and no whole leaves or branches in different periods; it is also used to measure the water potential of high water potential plants, such as crops in desert and arid regions, and also to measure and formulate daily water relations. Irrigation table.
Using the detection of the plant water potential pressure chamber, through the acquisition of relevant parameters, the crop water potential research data can be provided for agricultural monitoring. The emergence of plant water potential pressure chambers has promoted the development of water-saving agriculture in China and provided scientific irrigation information. It will not waste a drop of water, nor will it cause water shortage in plants.
