摘要:
采用全球卫星定位系统(GPS)对黑龙江省双城市双城镇中兴村土壤进行网格取样(100m ×100m), 用土壤养分系统研究法对大、中、微量元素进行分析。结果表明, 土壤中的营养元素均存在变异。根据土壤养分的抽样分布, 可将养分分为两类, 一类为偏斜型营养元素, 主要有氮、磷、硫等;另一类为不偏斜营养元素, 主要有钾、锰、铜、钙等。造成土壤养分偏斜的主要原因是施用化肥。对施肥历史较长, 且施肥量较大的偏斜元素进行施肥推荐时, 不仅要考虑地块的养分平均含量, 同时还要考虑土壤养分的空间变异状况;对于非偏斜元素的推荐施肥以大田土壤养分平均值即可。
Abstract:
244 soil samples w ere collected by g rid sampling(100m ×100m)using globle posi tion sy stem(GPS)in the Zhongxing village of Shuangcheng city of Heilongjiang province .The result indicatedthat the variance of the soil nut rient s had existed in the field .Based on the sampling distribut ion , thenutrients tested w ere divided into tw o classes .One w as called declining nut rient s, such as ni trogen ,phosphorus and sulfur , etc .The other was called non -declining nutrients , such as potassium , manganese , copper and calcium , etc .The main reason of declining was caused by supplying of chemicalfert ilizers .For the field w ith long history and large amount nut rients applyed , the fertilization recommendationmust be based on the spatial variability of soil nutrients , the others can be on the averagev alues of the soil test in the f ield .
