| 摘 要： | 文中对陕西省泾惠渠灌区土壤肥力现状进行了调查分析,并对土壤肥力质量做出了综合评价.结果表明:整个灌区土壤有机质含量处于较缺乏状态;土壤全氮为中等水平,但碱解氮含量较缺乏,土壤中速效磷和速效钾的含量丰富;从养分的空间变异系数看,以全磷最小,为12.6%,速效磷最大,为38.9%,速效磷在空间上分布最不均匀;土壤养分各因子...

| Abstract: | On the base of investigating and analyzing current situation of soil fertility in Jinghuiqu irrigation district of Shaanxi Province,comprehensive assessment of soil fertility has been researched.The results show that content of soil organic matter is still low level,and total N in soil is in the moderate level,but content of alkali-hydrolyzable N is a little low level.The contents of available P and K are much high level.The results of space variation coefficient of soil nutrients show that the coefficient ... |
