峡江烟区典型植烟土壤质量综合评价

Comprehensive Evaluation of Tobacco Planting Soil Quality in Xiajiang Tobacco Growing Area

为了解江西省峡江县植烟土壤的综合质量,采集了峡江县7个种烟乡镇,19个种烟村委的代表性土壤样品,采用描述统计和模糊数学法,综合分析了峡江植烟土壤理化性状和养分适宜状况。结果表明:峡江各乡镇的土壤容重较大、孔隙度小,pH值处于适宜和较低水平,土壤速效氮、有机质和速效磷含量相对偏高,土壤碳和速效钾含量偏低,有效硫含量适宜和偏高。在峡江烤烟种植中,应重视土壤综合改良降低土壤容重,减施氮肥及含磷元素的肥料,增施钾肥。

In order to analyze the comprehensive quality of tobacco growing soil in Xiajiang county, The epresentative soil samples from 7 tobacco-growing towns,19 tobacco-growing village committees in Xiajiang county were collected. The physicochemical properties and nutrient suitability of tobacco planting soil were analyzed by descriptive statistics and fuzzy mathematics. The results showed that: the soil bulk density of each sampling point was larger and the soil porosity was smaller, the pH value was at the appropriate and low level, the contents of available nitrogen,organic matter and available phosphorus in soil were relatively high, the contents of total carbon and available potassium in soil were low, and the content of available sulfur was appropriate and high. In the production practice of flue-cured tobacco in xiajiang,we should pay attention to the comprehensive improvement of soil, reduce the soil bulk density, reduce the application of nitrogen fertilizer and phosphorus fertilizer, increase the application of potassium fertilizer.
