Plant Stem Strength Tester

Instrument Introduction:

The strength of plant stems is a major factor determining the lodging resistance of crops. For a long time, lodging of corn, sorghum, tobacco, and other crops has caused great difficulties in mechanical harvesting. In terms of mechanization level, it causes a large amount of food waste. In addition, crop lodging leads to insufficient light, greatly limiting its production. Conducting in vivo measurements of crop stems at various stages of growth, and then statistically processing population measurement data based on the correlation between stem fiber layer bending resistance and lodging resistance, is of great significance for crop cultivation and breeding. The plant stem strength meter uses a tensile and compressive sensor to measure the maximum force generated at the moment of stem fracture or yield, that is, the strength of the stem, through needle punching, crushing, and breaking.

Features: 

1. Three different probes: capable of measuring stem bending performance, stem compressive strength, and stem tissue structure (puncture) strength; The bending bracket has adjustable distance and is marked with a scale.

2. Adjustable displacement ruler

3. Can be connected to a computer for testing, can save, print, perform various analyses, input speed and area, and display parameters such as displacement and pressure;

4. Can store 999 test values;

5. Large screen LCD display with backlight function and screen digital forward and reverse functions;

6. Automatic shutdown time setting;

7. Battery capacity display, automatically shuts down when the battery level is too low.
