root shoot ratio的意思|示意

The survival rate and growth of the first year showed a close relation with shoot-root ratio and height-diameter ratio.

造林成活率和当年生长量与茎根比和高径比关系密切。

With the improvement of rice cultivars, root dry weight and the ratio of root to shoot were increased, but the amount of root bleeding sap was reduced.

随品种的演进，抽穗期根重以及根冠比提高，但根系伤流液量减少。

The higher the precipitation, the greater the root depth, total root length and root diameter, the more lateral roots and the lower ratio of root to shoot.

降雨量越大，根系越深、总根长越大、根系直径越大、侧根越多、根冠比越低。
