- Intervention effect Soil Cu stress inhibited root growth of japonica rice Wuxiangjing 14.
- Intervention effect Damage to rice root growth increased with increasing soil Cu content.
- Intervention effect At the tillering stage, higher soil Cu content significantly decreased root activity per unit dry weight.
- Intervention effect At the tillering stage, lower soil Cu content had a small effect on alpha-NA oxidation ability per unit dry weight of root.
- Intervention effect The proportion of root growing before elongation decreased with increasing soil Cu content.
- Intervention effect The proportion of root growing after elongation increased with increasing soil Cu content.
- Intervention effect Alpha-NA oxidation ability per unit root dry weight was significantly enhanced at the heading stage with increasing soil Cu content.
- Intervention effect Alpha-NA oxidation ability per plant decreased with higher soil Cu content at the elongating and heading stages.
- Intervention effect Grain yield of rice decreased significantly with increasing soil Cu content on silty and loam soils.
- Association Root dry weight was positively correlated with grain yield of rice (r = 0.95).
