Introduction:

Lodging is one of the limiting factors for high yield and quality of crops. The severity of lodging and the loss of yield and quality are related to the crop growth environment and the occurrence period of lodging. Domestic and foreign scholars have conducted extensive and in-depth research on the lodging resistance of crops. It is suggested that the plant height, stem diameter and root-shoot ratio are significantly correlated with the lodging resistance. Lowering the plant height is the most effective measure to improve the lodging resistance. The base stem diameter, the inter-node dry weight and the wall thickness and the lodging resistance are significantly negative. Related. After the crops are laid down, the field is closed, the stems and leaves are mutually concealed, the ventilation and light transmission are poor, and the disease is serious, which affects the normal development of photosynthesis of plants and aggravates the occurrence of pests and diseases, so that the yield of photosynthetic materials decreases, the grain yield decreases, and the stems are simultaneously The transport function of the rod is also suppressed, and part of the nutrients are used for the curved growth of the stem. Resulting in a decline in crop yield and quality. Measuring the strength of crop stems and improving the lodging resistance of crops is of great significance for crop yield and mechanized harvesting. The DDY plant stalk strength meter uses a tensile pressure sensor to measure the maximum force generated by the stalk break or yield moment by acupuncture, crushing, and breaking, that is, the strength of the stalk.

Features:

1. Three different probes: can measure the bending performance of the stem, measure the compressive strength of the stem, and measure the strength of the stem structure (puncture); the distance of the bending bracket can be adjusted and marked with a scale.

2, can be measured with displacement scale

3, can be connected to the computer test, can save, print, do various analysis, input speed, area can also display displacement, pressure and other parameters;

4, can store 999 test values;

5, large-screen LCD display, with backlight function, and has the screen digital positive and reverse reversal function;

6, automatic shutdown time setting;

7, battery capacity display, the battery is too low to automatically shut down.
