When measuring the length of a coarse root, we divided it into two parts, which
are smaller and larger than 2 cm, to make it easier to calculate, and the results showed
that roots smaller than 2 cm were longer than roots larger than 2 cm. In general, the
coarse roots of the poplar (Populus euphratica olivier) can grow up to 200 meters in
length. The radius and depth occupied by the root were also determined during the
experiment. This value is important to us when choosing their spacing when planting
trees (Table 1).
Fine roots are the main nutrient-supplying part of plants, and their abundance
and large area increase the ability of plants to feed, resulting in good growth of the
aboveground part of plants and a decrease in groundwater (Graph 1 and Table 2).
