摘要:

为探究化肥与腐殖酸配施对烤烟产量和品质的影响,本研究以K326为试验材料,设置了5个化肥施用水平(G0:常规施肥;G1:常规施肥减量15%;G2:常规施肥减量30%;G3:常规施肥减量45%;G4:不施肥)和2个腐殖酸施用水平(H1:主要通过叶面喷施腐殖酸;H0:不施腐殖酸,施用等量清水),通过在云南楚雄烟区开展大田试验,分析了不同处理对植株表型性状、烟叶化学指标及烟叶产量和产值的影响。结果表明,楚雄地区烤烟种植中的常规化肥施用量超过了植株对养分的需求,在常规施肥量的基础上,将施肥量减少15%~30%后对烟叶的产量和产值无显著影响;施用腐殖酸(H1)会导致烟叶最大叶长、最大叶宽和叶片数增加,烟碱含量提高,总糖含量降低,产量、均价和产值分别增加6.60%、5.26%和11.68%,同时化肥施用量与腐殖酸的交互作用对烟叶表型性状、产量和产值的影响不显著。因此,在云南楚雄烟区烤烟种植中,将化肥施用量减少15%~30%,同时配施腐殖酸,能够有效提高烟叶产量和产值。

Abstract:

To investigate the effects of the combined application of chemical fertilizer and humic acid on the yield and quality of flue-cured tobacco,we used K326 as the experimental material in this study,and a field experiment was conducted in the tobacco-planting region in Chuxiong,Yunnan Province. The effects of five levels of chemical fertilizer(G0:conventional chemical fertilizer application rate;G1:reduced application rate of G0 by 15%;G2:reduced application rate of G0 by 30%;G3:reduced application rate of G0 by 45%;G4:no fertilizer application)and two levels of humic acid(H1:humic acid mainly applied as foliar fertilizer;H0:equal amount of water without humic acid)on plant phenotypic traits,tobacco chemical indexes,tobacco yield and its production value were analyzed. The results showed that the amount of conventional fertilizer applied to tobacco in Chuxiong exceeded the nutrient demand of the plants,as reducing the amount of conventional fertilizer by 15%-30% had no significant effect on the yield and production value of tobacco leaves. Compared with the treatment of water,applying humic acid(H1)increased the maximum leaf length,maximum leaf width and number of leaves;increased the nicotine content but decreased the total sugar content of the leaves. Furthermore,the yield,average price and production value of tobacco grown under H1 were increased by 6.60%,5.26% and 11.68%,respectively,compared with those grown under H0. Overall,there were no significant interactions between the effects of chemical fertilizer application rate and humic acid on the phenotypic characters,yield and production value of tobacco leaves. Therefore,reducing 15%-30% of the conventional chemical fertilization rate and applying extra humic acid could increase the yield and production value of tobacco leaves if tobacco is planted in the Chuxiong tobacco-growing area of Yunnan Province.
