摘要
应用原位显色法研究了不同施肥处理对马尾松(Pinus massoniana)苗木根际pH、Eh的变化以及对马尾松苗木生长的影响,结果表明:磷肥(P)和氮磷钾肥(N+P+K)对马尾松幼苗生长有明显促进作用且最有效地增大马尾松幼苗的酸化范围;磷肥(P)使得马尾松幼苗根际呈现最强还原态。
Experiments were conducted on effect of different fertilizer treatment on growth and rhizosphere of Pinus massoniana seedling.The results showed that application of P and N＋P＋K had obvious effect on growth of seedlings and could increase the scope of acidification.Application of P made rhizosphere the greatest reduced state.
