摘要
【目的】为探究生物炭用量对烤烟生长及产量、质量的影响。【方法】以烤烟K326和云87品种为材料,在安宁和寻甸两个不同气候生态点进行了不同用量生物炭(分别为0、450、600和750 kg/hm^2)对烟株生长及烟叶产量、质量的影响试验。【结果】不同生物炭用量明显影响烤烟烟株的生长、成熟、产量、产值和烟叶化学成分,且两个试验点皆有相似规律。生物炭施入土壤后,对生长阶段的烟株呈现出明显的前期抑制与后期促进的影响,且在烟叶初烤前,两地均以600 kg/hm^2处理长势最好;两个试验点烤烟的产量和产值也皆以600 kg/hm^2处理最好;而采烤期间的烟叶SPAD值在寻甸点以600和750 kg/hm^2处理,在安宁点以450和600 kg/hm^2处理相对更为适宜;初烤烟叶化学成分协调性在寻甸以750 kg/hm^2,安宁以600 kg/hm^2处理相对更好。【结论】建议烤烟生产中生物炭施用量以600 kg/hm^2处理为宜。
[ Purpose ] Our purpose was to explore the effect of biochar application amount on growth, yield and quality of Flue-cured tobacco plants. [ Method] Field experiments were conducted to study the influence of biochar in different amount i. g. 0, 450, 600 and 750 kg/hm2 respectively on the growth, leaves yield and quality of flue-cured tobacco plants with variety K326 in Xundian and Yun 87 in An'ning. [ Results ] The results indicated that tobacco plants' growth, maturity, yield, economic value and quality were significantly affected by biochar application amount. Moreover, similar tendency existed in two sites. Biochar application both resluted into undesirable growth in early stage, but better condition when approching to the harvest. Compared with the contrast, better growth, better maturity and the highest leaves yiled and economic value were obtained for the plants with biochar applied at600 kg/hm2. Meanwhile rational chemical components were found with biochar application amount at 600 kg/hm2 in An'ning and 750 kg/hm2 in Xundian. [ Conclusion ] It is suggested that biochar could be applied at 600 kg/hm2 in flue-cured tobacco production at the similar sites.
