桑植县植烟土壤中微量有效态营养元素含量状况分析

Analysis on the Contents of the Trace Available Nutrient Elements in Tobacco Planting Soil in Sangzhi County

为了解桑植县植烟土壤中微量有效态营养元素含量状况,共采集桑植县植烟土壤耕层109个土壤样品并进行了分析。结果表明:桑植县植烟土壤中微量有效态营养元素总体含量较高,但分布不均衡,各地区间差距较大,有效铁、有效锰、有效铜、有效锌、有效硼、有效钼、有效硫的含量均值分别为46.09、43.23、1.14、1.87、0.66、0.24、37.86 mg/kg,局部地区应重视补充锌、铜,桑植县优质烟叶生产应当采取控铁、锰、硫肥的措施。

In order to understand the contents of the trace available nutrient elements in Sangzhi's tobacco planting soil,109 soil samples in tobacco planting soil of Sangzhi county were collected and analyzed. The results show: the total content of trace available nutrient elements in tobacco planting soil is higher,but the distribution is not balanced,there are significant differences among different regions. The average contents of available iron、available manganese、available copper、available zinc、effective boron、effective molybdenum and available sulfur respectively are 46. 09,43. 23,1. 14,1. 87,0. 66,0. 24 and 37. 86 mg / kg. Zinc and copper should be supplied in some areas. In order to get high quality tobacco leaves in Sangzhi county,iron、manganese and sulfur fertilizer should be controlled.
