摘要
[目的]研究文山烟区植烟土壤有效态微量元素的丰缺特征,为烤烟生产均衡施肥提供科学依据.[方法]对文山州134个耕层土样的主要微量元素有效态含量进行分析.[结果]文山州土壤有效Cu、Fe、Mn含量丰富,平均含量分别为2.05、36.44和44.84 mg/kg;有效Zn含量为2.13 mg/kg,总体上属于中等水平,但各区域变幅较大:各烟区土壤的有效态微量元素含量以丘北县和广南县较为缺乏,砚山县含量较高,其余4县(市)含量中等;有效B含量为0.36 mg,/kg,属于较低水平,全州普遍缺B,分别有58.96％的土壤缺乏和26.12％的土壤严重缺乏.[结论]文山州植烟土壤有效态微量元素丰缺水平差异较大,需针对各元素丰缺特点制订相应的施肥措施.
Abstract
[Objective] The aim was to study the characteristics of available microelements in tobacco-grown soil in Wenshan and provide scientific basis for balanced fertilization in flue-cured tobacco production.[Method] The available microelements content in 134 soil samples collected from Wenshan was analyzed.[Result] The results showed that the average content of available Cu,Fe and Mn was 2.05,36.44 and 44.84 mg/kg respectively;the average content of available Zn was 2.13 mg/kg,which was on the medium level overall.However,there was a great difference among different areas:Qiubei County and Guangnan County were lack of available Zn,with a high content of Yanshan County;the soil was generally lack of available B,with a content of 0.36 mg/kg.There was a shortage and serious shortage in 58.96％ and 26.12％ soil samples respectively.[Conclusion] There are significant differences of available microelements in tobacco-grown soil in Wenshan,corresponding countermeasures for fertilization should be adopted according to each element characteristics.
