Abstract
The utility model relates to a ruler used for the shrub biomass non-destructive measurement. The ruler is a length measuring ruler which includes FT scales used for measuring the annual branch and leaf yield of a measured shrub and MFT scales used for measuring the above-ground biomass. The FT and MFT values of the shrub can be directly read corresponding to the canopy length of the measured shrub. The unit of the FT scales is gram, and the length corresponding to each gram is 1/-[Alpha]x cm, wherein the x represents the category of the measured shrub, the [Alpha] represents a shrub canopy-FT correlation coefficient. The unit of the MFT scales is gram, and the length corresponding to each gram is 1/[Beta]x cm, wherein the x represents the category of the measured shrub, and the [Beta] represents the shrub canopy-MFT correlation coefficient. The measured shrub can be rhus chinensis, coriaria sinica, Yichang magnolia, smilax china, cryptomeria fortunei, China fir, smallfruit rose root, thunberg lespedeza, or Viburnum erosum. The ruler is easy to carry, is simple in structure, is accurate in measurement result, and can rapidly measure the shrub biomass non-destructively, thus solving the shrub vegetation biomass measurement difficulty.
