| 摘 要： | 为了弄清土地整理后土壤理化性状指标、微生物数量以及烤烟产量和质量的空间变异情况,在福建三明烟区整理后烟田进行了大田取样分析和定点调查。结果显示,土地整理后土壤有效养分比全量养分空间变异大,变异系数超过30%;土壤微生物计数及多样性指数变异系数在66.17%～111.71%,均属于强变异;土地整理对烤烟产、质量均质性影响最大的是上、中等烟比例和糖碱比,烤烟产、质量的变异以285.91 m小范围为主。总之,土地整理后土壤理化性状和微生物数量空间变异明显,对烤烟产量和质量的均质性影响较大,需要进行改良。

| Abstract: | Soil samples were collected and measured from Ninghua of Fujian Province in order to identify the spatial variation in soil nutrients, physical properties, microbes and tobacco yield and quality after land consolidation. The results showed that soil available nutrient contents had larger spatial variation than those of total nutrients, with CV higher than 30%. The CV of soil microbe counts and diversity index were from 66.17% to 111.71%, indicting strong variations. Land consolidation mainly influenced the ratios between upper and middle grade leaves, between sugar and nicotine. Tobacco yield and quality varied mainly in range of 285.91 m. In conclusion, land consolidation can result in huge spatial variations in soil nutrients, physical properties and microbe counts, and can influence obviously tobacco yield and quality, so soil amelioration is necessary after land consolidation. |
