Research on leakage of nitrogen in the rotation field of rice and wheat under the conservation tillage

Abstract

Abstract

The purpose of this experiment was to research the leakage of nitrogen at the 60 cm depth of the rice field under the conservation tillage.The results showed that there was more NO^-₃-N losing in the rice field than NH⁺₄-N no matter it was tillage,no tillage or straw cover.From a certain angel,no tillage and straw cover played a promotional role for leakage of NO^-₃-N.
