为了明确南平烤烟最佳种植区域,综合考虑气候和土壤等15个生态指标,运用模糊数学隶属函数和相关系数法,对南平烤烟生态适宜性进行了综合评价。结果表明,气象因子中,旺长期气温、成熟期气温和旺长期降水量都适宜烤烟生长,但还苗伸根期降水量和成熟期降水量明显偏高,是烤烟生长限制性因子;土壤因子中,速效氮和速效磷含量适宜烤烟生长,而速效钾和有效硼明显偏低,为烤烟生长限制性因子。综合评价,建瓯、延平和顺昌为Ⅰ类适宜区;政和、浦城、松溪和建阳为Ⅱ类适宜区;光泽、武夷山和邵武为Ⅲ类适宜区。南平生态适宜性呈现由东南到西北从高到低的趋势。
In order to clarify the best planting area of Nanping flue-cured tobacco, comprehensive consideration was given to the ecological suitability of Nanping flue-cured tobacco by comprehensively considering 15 ecological indicators such as climate and soil, using fuzzy mathematics membership function and correlation coefficient method. The results showed that in the meteorological factors, the long-term temperature, the mature temperature and the long-term precipitation were all suitable for the growth of flue-cured tobacco, but the precipitation during mature period was significantly higher than that during mature period, which was the restrictive factor for the growth of flue-cured tobacco. , Available nitrogen and available phosphorus were suitable for the growth of flue-cured tobacco, while available potassium and available boron were significantly lower, which were restrictive factors for the growth of flue-cured tobacco. According to the comprehensive evaluation, Jian’ou, Yanping and Shunchang are suitable for Class I; Zhenghe, Pucheng, Songxi and Jianyang are suitable for Class II; and Guangze, Wuyishan and Shaowu are suitable for Class III. Nanping ecological suitability from southeast to northwest from high to low trend.
