氮肥配施秸秆和厩肥对土壤NH_4^+-N和NO_3^--N转化的影响

Effects of Nitrogen Fertilizer Combined Application with Straw and Stable Manure on Transformation of NH_4^+-N and NO_~3-N in Soil

设置了7个不同的施肥处理(①不施秸秆、氮肥和厩肥(CK);②单施氮肥;③麦秸+氮肥;④麦秸加倍+氮肥;⑤麦秸+氮肥+厩肥;⑥玉米秸秆+麦秸+氮肥;⑦玉米秸秆+麦秸+氮肥+厩肥),研究不同处理对冬小麦季土壤NH4+-N和NO3--N转化的影响。结果表明,氮肥配施秸秆和厩肥的处理冬小麦季土壤NH4+-N和NO3-N的数量均以冬前最高,施厩肥处理土壤NH4+-N和NO3--N的数量明显高于其他处理。

7 different fertilizer treatments（①without straw,nitrogen fertilizer and stable manure; ②nitrogen fertilizer application alone; ③wheat straw＋nitrogen fertilizer; ④double wheat straw＋nitrogen fertilizer; ⑤wheat straw＋nitrogen fertilizer＋stable manure; ⑥corn straw＋wheat straw＋nitrogen fertilizer; ⑦corn straw＋wheat straw＋nitrogen fertilizer＋stable manure） were set up to study the effects of different treatments on transformation of NH4＋-N and NO3-N in soil at winter wheat season. The results showed that the quantity of NH4＋-N and NO3-N in soil in treatments of nitrogen fertilizer combined application with straw and stable manure was the highest before winter,and that of NH4＋-N and NO3-N in soil in treatments with stable manure was obviously higher than that of other treatments.
