摘要

为研究武隆县植烟土壤的养分资源特征、丰缺状况

对烟区土壤进行综合评价

采用GPS定位对该县烟区主要乡镇土壤样品进行取样和测试分析。结果表明:武隆主要烟区土壤有机质含量适中;pH偏酸性;全氮含量较高

速效氮含量适中;不能为烟草提供充分的磷素的土样占总样品数的77.56%;近60%土壤速效钾含量适宜烟草的生长;中量元素中近60%烟田交换性钙含量偏高

多数土壤交换性镁含量在适宜至丰富范围

有效硫含量缺或不缺大致各占50%;有效锌含量分别占27.56%和62.50%

属于适中偏高;77.24%土壤有效铜含量丰富;有90%左右的土壤有效锰、有效铁含量偏高。土壤样品的IFI值在中等、较高、高、较低和低水平的分别为39.10%

33.01%

7.05%

17.63%和3.21%。综合评价认为武隆烟区大部分(占79.16%)土壤肥力较适宜生产烤烟。

Abstract

The characteristics of nutrients and conditions of abundance or scarcity were studied

and integrated evaluation were conducted with respect to soil planted with tobacco in Wulong county.The 312 samples were taked by GPS locating and analysed by laboratory test.The results showed that most samples are of moderate content of organic matter

pH are of weak acidity

higher content of total N

moderate content of available N

77.56% of samples are of P scarcity

approximately 60% of soils are suitable for tobacco gro...
