Treatment method for root system biomass of tree in karst region

Abstract

The invention discloses a treatment method for root system biomasses of a tree in a karst region. The treatment method comprises the steps of: 1) using the digging end of a digging and chopping dual-purpose pickaxe for digging surface soil open to expose a root system; 2) using the chopping end of the digging and chopping dual-purpose pickaxe for chopping side roots around a trunk; 3) after the side roots are chopped, pulling out the root system while using the pickaxe for digging the soil along the root growth direction; 4) after the side roots around the trunk are cleared, taking out the soil and using a steel shovel for obliquely and downwards cutting off a main root to gradually cut off the main root; 5) in the digging process, using the steel shovel for vertically cutting off main stressed side roots, and after the stressed side roots are separated from the main root, rooting up the tree; and 6) after the tree falls down, taking out all roots for clearing, and after non-root substances are cleared, classifying by stump, large roots, medium roots and small roots to obtain biomass data. The treatment method is feasible, the tools are simple to manufacture and are simple and convenient to operate, the time and the labor are saved, the root system of the tree can be obtained to the utmost extent and the accuracy of the data is guaranteed.

Description

technical field [0001] The invention relates to the technical field of forest cultivation, in particular to a treatment method suitable for arbor root system biomass in karst areas, which is suitable for forest resource inventory, forest community biomass investigation, and the current status of carbon sequestration in forest ecosystems. Background technique [0002] Forest is the main body of the global terrestrial ecosystem, and its biomass and productivity play a decisive role in the biosphere carbon cycle and biosphere-atmosphere exchange. Since the 1960s, the research on global forest biomass has developed rapidly, including the observation, analysis and simulation of forest biomass and productivity on the site, regional and global scales. In addition to site observation and remote sensing analysis, forest inventory data is an effective means One, it can also accurately estimate the biomass and productivity of forest vegetation on a larger scale, so as to provide basic ...

AI Technical Summary

Problems solved by technology

The research on forest biomass and productivity is particularly important. Due to the characteristics of barren, discontinuous soil and high rock exposure rate in karst areas, vegetation grows in rock crevices, and the root system cannot be fully dug, which especially increases the difficulty of underground biomass investigation and the lack of data. inaccuracy
