| 图2 不同土层根长生长量和死亡量对不同氮源配施的响应(平均值±标准误差)。同一土层中的不同字母表示差异显著(p < 0.05)。T0, 不施肥; T1, 100%尿素N; T2, 75%尿素N + 25%鸡粪N; T3, 50%尿素N + 50%鸡粪N; T4, 25%尿素N +75%鸡粪N; T5, 100%鸡粪N。 |
| Fig. 2 Response of root length density production (RLDP) and root length density mortality (RLDM) to different ratios of nitrogen source in different soil layer (mean ± SE). Different letters indicate significant differences at p <0.05 in the same soil layer . T0, 0 g N; T1, 100% N from urea; T2, 75% N from urea + 25% N from chicken mature; T3, 50% N from urea + 50% N from chicken mature; T4, 25% N from urea + 75% N from chicken mature; T5, 100% N from chicken mature. |
