Abstract

Abstract

In order to study the effects of different fertilization methods on runoff nitrogen in Phyllostachys edulis forest, typical shoot-use Ph. edulis forest were selected, eighteen runoff experimental fields were established and the NH₄⁺-N, NO₃^--N, TN, TP in runoff water samples were tested. The results shows that the contents of NH₄⁺-N, NO₃^--N and TN in runoff waters were increased sharply and decreased slowly after fertilization in Ph. edulis forest, while no uniform variation tendency observed across whole study. During whole test times, the annual runoff amount of NH₄⁺-N, NO₃^--N and TN were all as following ordering: scatter application > furrow application > hole application, in which the annual runoff amount of NH₄⁺-N, NO₃^--N and TN for scatter application treatment were 228 g·hm^-2, 178 g·hm^-2 and 418 g·hm^-2, respectively. And the runoff amounts of NH₄⁺-N, NO₃^--N and TN in hole application treatment Ph. edulis forest were 101 g·hm^-2, 104 g·hm^-2 and 418 g·hm^-2, respectively. The results of significance analysis showed that the single loss of NH₄⁺-N in the scatter application treatment was significantly higher than that in the furrow and hole application treatment on May 8th and June 10th (P<0.05), the single loss of NO₃^--N was only on April 9th, and there was a significant difference between scatter application and hole application (P<0.05). However, in the whole test cycle, there was no significant difference in TN loss between different treatments (P>0.05).
