| 摘 要： | 采用蒋柏藩-顾益初无机磷形态分级方法对黄河三角洲盐碱地试验田、藤柳林、芦苇地和石榴林4种不同利用方式下土壤无机磷组分特征进行了研究.结果表明,4种不同利用方式下盐碱地土壤无机磷各形态以Ca8-P、Ca10-P和Al-P为主,约占无机磷总量的77.41%,其中以钙结合态磷所占的比例最大,即盐碱地不同利用方式下土壤无机磷含量是以钙磷为主.石榴林由于在土壤中加入了石灰质,改变了土壤的特性且对土壤中Al-P含量影响较大,Al-P含量高达205.0 mg/kg,显著高于其他土地利用方式.盐碱地4种不同利用方式下土壤中O-P和Ca8-P含量相差不大,土地利用方式对土壤中O-P和Ca8-P含量影响较小.

| Abstract: | Inorganic phosphorus component characteristics of the four different saline soils on Yellow River Delta Region are studied in the paper.There are experimental field,willow,reed,and pomegranate field,respectively.The results show that Ca8-P,Ca10-P and Al-P accounted for 77.41% in total inorganic phosphorus.Calcium phosphate is the most important form.Al-P content is 205.0mg/kg which is higher than other forms of land use for applying lime.O-P and Ca8-P content are equivalent in the four kinds of land utilization and land using patterns less affected O-P and Ca8-P contents. |
