黄泛平原区不同土地利用方式下的土壤养分状况分析

选取黄泛平原区菜地、水浇地、果园和有林地4种不同的土地利用方式,通过野外调查与室内分析,研究不同土地利用方式对土壤养分的影响。结果表明:土壤pH值有林地与果园相对较高,水浇地和菜地较低,均呈弱碱性;土壤有机质、速效钾、有效磷和全氮含量均受土地利用方式影响较大,并且均为菜地含量最高,水浇地次之,林地含量最小,土壤缓效钾受土地利用方式影响不显著;土壤有效硫含量由大到小为菜地水浇地果园有林地,与有机质相同;有效锌、有效铜和有效铁在水浇地中含量较高,有效猛、有效钼和有效硼在有林地中含量较高,菜地的微量元素含量普遍较低。

Analysis of Different Cultivated Land Use Types on Soil Nutrients in the Yellow River Alluvial Plain Area

The soil is natural resources for human survival, and land use is the most important and most direct activity of human intervention. The effects of different land use patterns on soil nutrient content can provide a basis for the rational use of land resources and the efficient production of crops. This study selected Heze city of the Yellow river alluvial plain area as the study area. There are four land use types: vegetableSland, irrigableSland, orchard, and forestSland, and 13 kinds of nutrient data: N, P, K and organic matter, etc. By using the software of SPSS ANOVA single factor variance analysis method, effects of different land use types in plain area of Yellow River on soil nutrients was studied. The results showed that: The soil pH value of forestSland and orchard was relatively high while the value of irrigated land and vegetable land was relatively low, but they were all weakly alkaline; the contents of soil organic matter, available K, available P and total N were greatly influenced by land use, and the ranking of content from high to low was vegetableSland, irrigableSland, orchard, and forestSland, but the effect of land use on the slowly available K was not significant; The ranking of available s content from high to low also was vegetableSland, irrigableSland, orchard, and forestSland, same as organic matter; Higher content of available Zn and available Cu and available Fe were in irrigated, while available Mn, available Mo and available B in forestSland was higher, and the content of microelement in the vegetable land was generally low. The research results will provide scientific basis for soil fertilization and utilization management in Yellow River Alluvial Plain Area, and it has positive guidance for rational utilization and protection of land resources in this area.
