摘要
通过田间试验研究了中耕培土后垄面覆盖小麦秸秆对烟株农艺性状、根系及整株干物质累积、养分吸收和烟叶产量、产值和品质的影响。结果表明:中耕培土后垄面覆盖小麦秸秆对烟株前期的生长影响不大,但对打顶后烟株的生长有一定的促进作用;覆盖秸秆烟株表现为中、上部叶片扩展更好,叶面积系数增加,体内干物质累积和养分吸收增多。覆盖秸秆处理烟叶产量、产值和上等烟比例均显著高于对照,而在烤后烟叶化学成分含量和评吸结果方面,处理与对照较为接近。
Field experiment was conducted to study the effects of mulching with wheat stalk after cultivation and earthing up on the agricultural characters, roots, dry matter accumulation, nutrient uptake, yield, and quality in flue-cured tobacco. Results showed that mulching with wheat stalk after cultivation and earthing up had little effect on early growth of tobacco plants, while promoted the growth after topping. The plants mulched had a bigger leaf area for the leaves on the upper and middle position of the stalk, accumulated more dry matter, and absorbed more nitrogen, phosphorus and potassium than contrast, resulting in higher yield and total revenue. However, no significant difference was observed between tobacco plants with and without mulching with regard to chemical content and smoking evaluation.
