摘　　要：为科学评价植烟土壤养分的适宜性,以皖南产区植烟土壤为研究对象,采用云模型理论对植烟土壤主要养分指标进行了综合评价。结果表明:①皖南植烟土壤养分含量(质量分数)整体处于适宜水平,云模型参数为Cloud={Ex=0.559 8,En=0.089 2,He=0.016 9};②从土壤单项养分指标来看,皖南植烟土壤中全磷、全钾、速效钾含量偏低,且养分分布的随机性和模糊性(熵和超熵)稍大,养分云滴雾化状态较为明显,表明皖南烤烟生产上在土壤养分平衡方面仍存在一定的改进空间。皖南土壤养分整体处于适宜水平,但单项土壤养分指标磷和钾含量偏低。In order to evaluate the suitability of nutrients in tobacco-growing soils,soil samples were collected from southern Anhui,and major soil nutrient indexes were comprehensively evaluated based on a cloud model algorithm.The results showed that:1)The nutrient contents(mass fraction)in the tobacco-growing soils were generally suitable,the parameters of the cloud model were Cloud={Ex=0.5598,En=0.0892,He=0.0169}.2)Viewing from the single index of soil nutrients,the contents of total potassium,total phosphorus and available potassium were low,the randomness and fuzziness of soil nutrient distribution were high and the atomized droplets of nutrients were significant,which indicated that the nutrients in tobacco-growing soils in southern Anhui still needed to be balanced.In conclusion,the nutrients in tobacco-growing soils in southern Anhui are generally suitable for tobacco growing,but the contents of potassium and phosphorus were low.
