【摘要】 对湖北省4个不同地区典型水稻土的磷(P)、钾(K)、硫(S)、硼(B)、锌(Zn)的吸附能力进行了研究。4种水稻土对P的吸收能力大小顺序为:洪湖市油-稻两熟区近代河流冲积物母质发育的水稻土(4#土)>襄樊市麦-稻两熟区Q3母质发育的水稻土(3#土)>荆门油-稻两熟区Q3母质发育的水稻土(2#土)>蕲春县油-稻-稻三熟制区花岗片麻岩母质发育的水稻土(1#土);对K的吸收能力大小顺序为:3#>4#>1#>2#;对S的吸收能力大小顺序为:3#>2#>4#>1#;对Zn的吸收能力大小顺序为:3#>4#>2#>1#;对B的吸收能力大小顺序为:3#>4#>1#>2#。田间养分管理策略应根据不同地区土壤对养分的吸附能力大小进行相应调整。更多还原

【Abstract】 Phosphorus（P）,potassium（K）,sulfur（S）,boron（B） and zinc（Zn） fixation characteristics by four typical paddy soils in different regions in Hubei Province was studied.The order of P fixation capacity was the paddy soil from alluvial deposit parent material under rapeseed-rice rotation in Honghu City(4^# soil) > that from Q₃ parent material under wheat-rice rotation in Xiangfan City(3^# soil) > that from Q₃ parent material under rapeseed-rice rotation in Jingmen City(2^#soil) > that from granite gneiss parent material under rapeseed-early rice-late rice rotation in Qichun County(1^# soil).The order of K fixation capacity was 3^# soil > 4^# soil>1^# soil> 2^# soil.The order of S fixation capacity was 3^# soil > 2^# soil > 4^# soil>1^# soil.The order of Zn fixation capacity was 3^# soil > 4^# soil> 2^# soil >1^# soil.The order of B fixation capacity was 3^# soil > 4^# soil>1^# soil > 2^# soil.Field nutrients management should be regulated according to soil fixation ability on the nutrients.更多还原
