摘    要:用聚类分析方法,对施入亚铵造纸制浆黑液、有机肥及化肥的石灰性轻壤质褐土和砂壤质水稻土的理化性质、微形态特征及生产力等方面的20多种指标进行了综合分析,明确了亚铵制浆黑液在一些常规肥料中的地位。在褐土中,亚铵制浆黑液的作用与堆肥类似;在水稻土中,作为基肥的亚铵制浆黑液对土壤系统的贡献与堆肥+N 是同一水平的。

关 键 词:聚类分析  制浆黑液  肥料地位

Abstract:Acording to the effects of straw-paper-pulping wastes using ammonium sulfite(SWUAS), rice straw compost,rice straw and chemical fertilizer of soil chemical and physical properties,microstruc- ture characteristics and productivity of calcareous Drab soil and Paddy soil,the position of the wastes among normal fertilizers was determined by cluster analysis method.The result showed that the effect of the wastes on Drab soil was similar to that of rice straw compost,and its effect on Paddy soil was at the same l...
Keywords:cluster analysis  pulping wastes  fertilizer position
