| 摘 要： | 对铜仁4个主要植烟县90个植烟土壤样本中有效态微量元素进行测定,并分析其分布特点。结果表明:铜仁地区植烟土壤有效锌含量适宜,平均为1.94mg/kg,但缺乏及潜在缺乏土壤占20.00%;有效铜、有效铁和有效锰含量极丰富,平均分别为30.88、37.77和1.20 mg/kg;水溶性氯含量适宜,平均为12.79mg/kg;有效硼含量较低,平均为0.41mg/kg,有71.11%的土壤样本含量在烤烟生长的临界值以下,属缺乏状态,急需补充肥。有效铁和硼的含量与有效锌含量存在显著正相关关系;土壤有效铁与有效铜、锰间存在极显著正相关关系。这几种微量元素含量及分布在不同植烟县间都存在差异。在生产过程中,针对不同烟区的土壤微量元素状况,应在烤烟专用复合肥施用的基础上,因地制宜地增施相应微肥。

| Abstract: | In order to investigate microelements in tobacco growing soil of Tongren and supply micronutrients to tobacco fields to improve the production and quality of tobacco,the microelement nutrients in 90 soil samples collected from 4 tobacco growing counties in Tongren were analyzed,and their distribution was evaluated.The results showed available Zn content was adequate with the mean of 1.94 mg/kg,but 20.00% of the tobacco planting soil lacked Zn or potentially lacked Zn;Available Cu,Fe and Mn contents were very rich in the tobacco-growing soils of Tongren with the mean of 1.20 mg/kg,30.88 mg/kg and 37.77 mg/kg,respectively;Solution Cl content was adequate with the mean of 12.79 mg/kg;Available B content was low with the mean of 0.41 mg/kg and those in 71.11% soil samples were less than the critical value,so additional supplyment of B fertilizer was required.The contents of available Fe and B had a significant positive correlation with the contents of available Zn.The contents of available Fe had a significant positive correlation with available Cu and Mn.The contents and distributions of soil microelements had discrepancy in different counties.So,microelement fertilizers should be applied according to the local soil microelement status. |
