The Effect of Plant Water Potential Pressure Room on Water Saving Agricultural Construction

August 27, 2019

The roots of the plant constantly absorb water from the soil, and the leaves continue to lose moisture to the surrounding environment. Therefore, the plant's rhizome and leaves have a certain gradient of water potential, so that the tiny water column in the xylem conduit is affected by the negative pressure of the low water potential of the air and forms moisture. Pull up to transport. When the plant shoots or leaves are cut, the tensioned water column in the conduit breaks and the water column shrinks from the incision to the interior of the upper end. The cut material is loaded into the pressure chamber of the instrument (see the operating procedure below), and one end of the cut out is sealed outside and pressurized, so that the tension in the shoot or blade rebalances and pushes the small water column back to the cut surface. All the pressure is the water potential of the plant. The plant water potential pressure chamber is the instrument for measuring the water content of plants, and the main equipment for researching crop irrigation water. However, many users still do not understand the principle and use of the instrument. This article gives you a brief introduction.

The principle of the plant water potential pressure chamber is to clamp the plant leaves or branches in the sample chamber and pressurize the gas to observe the pressure when the first droplet of tissue fluid seeps out. The pressure at this time is the water potential of the plant-like tissue. The pressure chamber is used to measure the water potential of entire area, 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 perform daily water relationship measurement and formulate irrigation tables. . Through the acquisition of this parameter, 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, provided scientific irrigation information, did not waste water and did not lead to water shortage in plants, saved water resources, increased the utilization of water resources, and increased the Yield and quality.

Weld-Neck Flange

Weld-neck flange is a kind of flange that butt welds the pipe with the neck.

Production Size:1/2"-96"

Pressure range:PN16,PN25,PN40,PN64,PN100,PN250

Production Standard:BS,JIS,GOST,ANSI,DIN,GB

Main Material of parts:

A105,A350-LF2,A182-F5,A182-F11,A182-F304,A182-F304L,A182-F316,A182-F316L,A234-WPB,A420-WPL6,A234-WP12,A234-WP11,A234-WP5,A403-WP304,A430-WP304L,A403-WP316,A403-WP316L

The shape of Weld-neck flange isn`t easy to change,The sealing performance of Weld-neck flange is very good.It is wildly applied. Weld-neck flange is suitable for pressure or temperature fluctuations of the pipeline or high temperature and high pressure and low temperature pipeline,generally used for connecting pipes and valves of above 2.5MPa; Weld-neck flange is also used in the pipeline which transport expensive, flammable and explosive medium.
