How to measure cotton leaf area with leaf area meter

Cotton leaf is an irregular shaped leaves, when the need to measure this type of leaf area, we need to adopt a certain measure instrument, after scientists found that leaf area meter can be measured in any shape, size, thickness of the blade, Of course, there are other methods besides the leaf area meter. Let's take a look.
In the past, we used the traditional method of measuring the length, width, and post-imprinting weighing or quadrature conversion of the metering blade, which is not only time-consuming and accurate. In recent years, the company has been able to save cotton area data on site and store 2,000 data at one time. The leaf area meter can measure the leaf area, average leaf area, night length, leaf width, and long section ratio of the cotton leaf surface, and the data can be imported into the computer.
The change of cotton leaf area is also related to the dry matter weight of each plant. The dry weight of single plant has grown rapidly since the flowering of cotton. The dry weight per plant was consistent with the time-varying trend of the leaf area per plant. That is to say, the leaf area per plant is increased, and the dry weight per plant is also relatively increased.
There are many ways to determine the number of pages per plant of cotton. The use of dot boards and perforation weighing methods, although high accuracy, suitable for indoor, but also to retrieve the leaves of the whole plant, the process is cumbersome, and the speed is slow, only applicable to the research unit . The use of the long-width coefficient method and the deblade tip method must also be measured field by tree from leaf to leaf. The work schedule is particularly slow when it takes time and labor, and the standard is difficult to master. The workload is large when calculated. Improper method of measurement will appear. Big error. The leaf area meter can measure the leaf area and related parameters of the cotton leaf accurately, quickly and without damage, and can also measure the area of ​​the cotton leaf and other sheet objects picked. The leaf area meter uses the plate to measure the page instead of using the stretching method. The measurement speed is faster and the result can be obtained in 1 second.
The leaf area meter is a convenient and portable detection instrument. The instrument will not damage the leaf area and will not affect the plant growth. The leaf area meter is also called the leaf area detector, in addition to measuring the plant area. , It is also a good instrument to obtain the aspect ratio and perimeter. The instrument will automatically save the measurement results.

our dished heads are used in a variety of applications and industries such as storage tanks, pressure vessels, road tank, food processing operations, chemical plants ,Nuclear operation, Oil Refining, Architectural feature, power generation.

Due to our forming experience and equipment, we can spin or press the first part of the process of forming your products, It depend on the thickness and material performance,

Our main products are 2:1 SE dished heads, Torispherical heads, Cones,Hemispherical Heads etc

Choosing the right type is the key decision for each customer and one for which our experience team to happy to give advice, simple speaking, the torispherical heads, the less ressure it can withstand, Conversely, the deeper dished heads, for example Elliptical heads, hemispherical, the greater pressure it can take.

Our in house-capability to form dished heads by cold press brings major benefits to our customers and sets us apart from others dished heads manufactures

For carbon steel dished heads, we can forming this dished heads from 76-9000mm in diameter and below 250mm in thickness  

The general forming process as the below sketches forming process

Technical Delivery Condition
1,Our material (hot Rolled Unalloyed structural steel, high and low temperature steel, High Alloy steel)
We have no carbon steel plates in our stock and most of plates are from Chinese steel market or mill. Meanwhile As Japanese owed company, We can also source the plates from Japanese ex-mill if end user can`t accept ex-chinese mill.
Basically the delivery time shall be below 20days for dished heads if plates are from steel market. and Max plates width from them is below 2200mm. it means that the seamless dished heads diameter shall be below about 1800mm.
The max width CS plates that Chinese mill can do is below 4700mm,and dished heads can be seamless below 3800mm in
