YYD series digital display plant stem strength detector instruction manual

YYD series digital display plant stem strength detector instruction manual

Thank you for choosing the products and services of Zhejiang Top Instrument Co., Ltd.

Please read the instruction manual carefully before using the product.

First , the functional characteristics

The YYD series digital plant stem strength tester is a key factor in determining the lodging resistance of crops. The lodging of plants such as corn, sorghum and tobacco poses great difficulties for the mechanical harvesting of crops. Cause a lot of waste. In addition, the lodging of crops leads to insufficient illumination, which limits their production. The stalks are measured in vivo at various stages of crop growth, and the population measurement data are statistically processed according to the correlation between the bending resistance and the lodging resistance of the stalk fiber layer, which is of great significance for crop cultivation and breeding.
