It can test plant Culm-strength. The stem intensity of sorghum, maize, and tobacco is a major factor to decide the lodging-resistance ability. The lodging of sorghum, maize, and tobacco have caused great difficulties in crops mechanized harvesting for a long time. From current mechanization harvest level, a lot of crop is wasted. In addition, corn lodging, causing inadequate illumination makes its yield enormous limit. To cultivate high intensity stem of crop seed, the instrument applies to agricultural genetic breeding.

The stems with a rubber strip and accessories together, and placed in the ground 20cm high. Note rice when measuring direction, as shown below:
Under this heigh, stem promote crop at right angles to the case until the crop and land surface at a 45° angle, as shown above.
Why measure the stem strength of crops?
For a long time, plant lodging has been an important factor restricting the high and stable yield of food crops, and the main indicators affecting plant lodging resistance include the bending, compressive strength, puncture strength, etc. of plant stems. These indicators can be measured using a stem strength tester, especially when identifying and selecting high lodging resistant varieties. The excellent quality of stems and the main period, factors, and degree of influence that affect stem strength can be measured through this instrument, providing a theoretical basis for high-yield cultivation, variety selection, and mechanized production of crops.
Taking corn as an example, when evaluating the quality of corn varieties, we usually look at the size of the corn cob and the appearance of the plant. In fact, what we need to look at is the comprehensive characteristics of corn, mainly including root system, stem, ear position, plant height, leaves, etc. Among them, stem is a particularly important factor. The stem, regardless of its thickness, must be strong and elastic. Corn with good toughness and strong hardness has the characteristics of strong lodging resistance and high nutrient transport ability. In addition, a shorter basal internode is also an excellent trait for lodging resistance.
The YYD series stem strength tester adopts high-precision mechanical and tilt sensors, which can obtain real-time force magnitude and tilt angle, and visually display the corresponding curve relationship between force and tilt angle. Through embedded analysis models, the anti lodging performance level can be obtained, providing data support for evaluating crop anti lodging ability. And this instrument can not only measure the stem strength of corn, but also measure the stem strength of crops such as wheat, sorghum, and rice. It can be said that with the measurement of plant stem strength tester, growers can judge the condition of crop stems at an early time, and guide planting based on common reasons to ensure reasonable and high-quality growth of crops. And it can guide the breeding of seeds with high stem strength, making crop cultivation more efficient.
