摘　　要：基于广西贺州植烟区土壤普遍缺乏硼、钼2种微量元素,在贺州市富川县富阳镇进行大田试验,以叶面喷施清水为对照,探究硼钼肥不同喷施次数对烤烟产量、产值和化学成分的影响,以筛选适合该区域的硼钼肥施用方案。结果表明,叶面喷施硼钼肥显著提高烟叶产量和产值,产量提高16.08%~24.36%,产值提高20.84%~27.19%;叶面喷施硼钼肥显著提高了烟叶总氮含量且使其更接近最适值,降低了烟叶的总糖和还原糖含量,对改善协调烟叶化学成分起一定作用,同时明显提高烟叶的硼含量和钼含量。结合烤烟生产的用工成本,在烤烟现蕾打顶期叶面喷施0.06%硼肥、钼肥是贺州植烟区最佳的增施硼钼肥技术方案。Based on the widespread lack of boron and molybdenum in the soil of Hezhou tobacco planting area in Guangxi,a field experiment was conducted in Fuyang Town,Fuchuan County,Hezhou City.In order to screen suitable boron and molybdenum fertilizer application plans for the region,the effect of different spraying times of boron and molybdenum fertilizer on the yield,output value,and chemical composition of flue-cured tobacco was investigated,with clear water sprayed on the leaf surface as the control.The results showed that foliar spraying of boron and molybdenum fertilizer significantly increased the yield and output value of tobacco leaves,with an increase of 16.08%-24.36%in yield and 20.84%-27.19%in output value.Spraying boron and molybdenum fertilizer on the leaves increased the total nitrogen content of tobacco leaves and made it closer to the optimal value,reduced the total sugar and reducing sugar content of tobacco leaves,played a certain role in improving the coordination of tobacco chemical composition,and significantly increased the boron and molybdenum content of tobacco leaves.Considering the labor cost of tobacco production,spraying 0.06%boron and molybdenum fertilizer on the leaf surface of flue-cured tobacco in budding stage is the best technical plan for the application of boron and molybdenum fertilizer in Hezhou tobacco planting area.
