南平烤烟种植生态适宜性评价

Ecological Suitability Evaluation of Nanping Tobacco Planting Areas

摘要

摘要: 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。

Abstract: In order to define the best planting regions of flue-cured tobacco in Nanping, the ecological suitability evaluation was studied by using 15 factors of climates and soils, based on the analysis of fuzzy mathematics and correlation coefficient. The results indicated that temperature and rainfall of fast growing period, temperature of maturing stage, soil available nitrogen, and soil Olsen-P were suitable for tobacco growth, but precipitation of seedling and maturity, available potassium, and available boron were limiting factors. The tobacco growth region in Nanping were divided into three classes, the first includes Jianou, Yanping and Shunchang, and the second includes Zhenghe, Pucheng, Songxi and Jianyang, while in the third includes Guangze, Wuyishan and Shaowu. In Nanping, ecological suitability for flue-cured declined from southeast to northwest.
