| 摘 要： | 根据内江市白马镇5种土地利用类型,采集表层土壤样品172个,共分析测试了有机质、全氮、水解性氮、有效磷、速效钾、阳离子交换量6项土壤养分指标,以了解不同土地利用状况对土壤肥力的影响。结果表明,有效磷含量变化趋势为:果园>灌溉水田>疏林地>望天田>旱地;全氮:望天田>灌溉水田>疏林地>果园>旱地;水解性氮、速效钾、阳离子交换量含量变化趋势相同,均为:望天田>灌溉水田>疏林地>旱地>果园;有机质含量变化趋势为:灌溉水田>望天田>疏林地>果园>旱地。

| Abstract: | According to the 5 land use types in Baima Town of Neijiang City,172 topsoil samples were collected.7 soil nutrient indices were analyzed,which were organic matter,Total N,hydrolyzable N,rapidly available P,available K,slowly available K and cation exchange capacity,in order to find out the effects of different land use on soil fertility.Result showed that the change tendency of available P content was orchard>irrigated paddy field>open forest land>non-irrigated field>dry land,that of total N was non-irrigated field>irrigated paddy field>open forest land>orchard>dry land.The change trends of hydrolyzable N,available K,slowly available K and cation exchange capacity were the same,which was non-irrigated field>irrigated paddy field>open forest land>dry land>orchard.And the change tendency of organic matter content was irrigated paddy field>non-irrigated field>open forest land>orchard>dry land. |
