Product description:
The lodging of maize, sorghum and tobacco has caused insufficient illumination, and in turn enormously limited crop yields for a long time. Meanwhile, it has also caused great difficulties in crop mechanized harvesting, thus a lot of grains have been wasted. This instrument can test plant stem strength, and it applies to genetic breeding in agriculture as well.
