土壤氮是水稻氮素营养的主要给源.不同土壤具有不同的供氮容量与过程.本试验着重比较太湖平田地区黄泥土和白土两种分布较广的水稻土的供氮特性,探讨其与三熟制早稻(以下简称早稻)合理施肥的关系.现将土壤供氮特性部分整理如下.
Soil nitrogen is the main source of nitrogen nutrition for rice.The different soils have different nitrogen supplying capacity and process.This study focused on comparing the nitrogen supplying characteristics of two widely distributed paddy soils in Pingtan, Three ripening early rice (hereinafter referred to as early rice) the relationship between rational fertilization.Now the characteristics of soil nitrogen are arranged as follows.
