会理县是四川主要的烤烟种植区之一,基于会理县主要植烟乡镇269份土壤样品的养分指标,运用模糊综合评价法对会理县燥红壤、红壤、棕壤、黄棕壤、紫色土、水稻土和石灰岩土七种植烟土壤进行综合肥力评价。结果表明会理烟区7种土壤类型的肥力综合指数是:石灰岩土>黄棕壤>水稻土>红壤>棕壤>紫色土>燥红壤;石灰岩土和黄棕壤Ⅰ级土壤所占比例较大;水稻土Ⅱ级和Ⅲ级分布较多;棕壤、紫色土、燥红壤大部分为Ⅳ级;红壤各等级分布比较平均。各土壤类型肥力状况差异较大,石灰岩,黄棕壤和水稻土相比较优,红壤、棕壤、紫色土和燥红壤要根据具体情况进行肥力改造。
Huili County is one of the main flue-cured tobacco planting areas in Sichuan Province. Based on the nutrient indexes of 269 soil samples collected from major tobacco-producing townships in Huili County, Huili County, Hubei Province, Purple soil, paddy soil and limestone soil seven planting soil comprehensive evaluation of fertility. The results showed that the comprehensive index of fertility of seven soil types in Huili area were as follows: limestone soil> yellow brown soil> paddy soil> red soil> brown soil> purple soil> dry red soil; limestone soil and yellow brown soil Grade I soil The distribution of grade II and grade III in paddy soil is more. The brown soil, purple soil and red soil are mostly Grade IV, and the red soil is relatively average in all grades. The fertility of each soil type is quite different, and limestone, yellow-brown soil and paddy soil are better than others. Red soil, brown soil, purple soil and dry red soil should be reformed according to specific conditions.
