聚天门冬氨酸与壳聚糖配施对烤烟生长及烤后烟叶品质的影响OA
Effects of Combined Application of Polyaspartic Acid and Chitosan on Growth of Flue-Cured Tobacco and Quality of Cured Tobacco Leaves
为明确聚天门冬氨酸(PASP)与壳聚糖(CTS)配施对毕节干旱地区植烟土壤含水率、烟株及根系生长发育、烟叶品质的调控效应,以云烟 87 为试验材料,施加不同浓度PASP及CTS(CK:施等量清水;T1:3.0 kg/hm2 PASP,0.3 kg/hm2 CTS;T2:3.0 kg/hm2 PASP,0.6 kg/hm2 CTS;T3:6.0 kg/hm2 PASP,0.3 kg/hm2 CTS;T4:6.0 kg/hm2 PASP,0.6 kg/hm2 CTS),测定烤烟不同生育期植烟土壤及根系指标、烟株生长发育指标及烤后烟叶品质指标.结果表明,与其他处理相比,T3 处理对土壤含水率提升显著,团棵期浅层土壤含水率相较CK处理提升 15.01%,深层土壤提升10.16%.T4 处理对侧根、不定根数目、根体积及根系活力提升显著,与CK处理相比分别提升 34.07%、29.12%、25.70%和 29.56%.二者配施对烤烟生长发育及干物质积累提升显著,浓度越高作用效果越明显,与CK处理相比,T4 处理叶面积及茎围分别提升 18.3%和 12.3%,干物质积累量提升26.04%.烟叶化学成分、感官及外观质量均得到不同程度的提升,T2 处理提升效果最显著,与CK处理相比分别提升10.36%、7.76%和 7.30%.烟叶质量评价较CK处理提升 7.57%.PASP与CTS配施能够有效提升土壤含水率,促进烤烟根系发育,改善烟叶品质.3.0 kg/hm2 PASP与 0.6 kg/hm2 CTS处理综合表现最优,可有效缓解干旱导致毕节烟区烤烟产质量下降的问题.
To clarify the regulatory effects of a polyaspartic acid(PASP)combined with chitosan(CTS)on soil moisture content,tobacco plant and root growth and development,and tobacco leaf quality in the arid tobacco area of Bijie,field experiments were conducted using Yunyan 87.Different concentrations of PASP and CTS(CK:same amount of water;T1:3.0 kg/ha PASP+0.3 kg/ha CTS;T2:3.0 kg/ha PASP+0.6 kg/ha CTS;T3:6.0 kg/ha PASP+0.3 kg/ha CTS;T4:6.0 kg/ha PASP+0.6 kg/ha CTS)were applied.Soil and root indexes,growth and development parameters and quality indexes of flue-cured tobacco leaves were measured at different growth stages.The results showed that compared with other treatments,T3 treatment significantly increased soil moisture content.At the rosette stage,the moisture content of the shallow soil layer increased by 15.01%and that of deep soil layer increased by 10.16%compared with CK.T4 treatment significantly increased the number of lateral roots and adventitious roots,as well as root volume and root activity,by 34.07%,29.12%,25.70%and 29.56%respectively compared with the CK.The combined application of PASP and CTS significantly promoted growth,development,and dry matter accumulation of flue-cured tobacco,with higher concentrations leading to more obvious effects.Compared with CK,the leaf area and stem circumference of T4 treatment increased by 18.3%and 12.3%respectively,and the dry matter accumulation increased by 26.04%.The chemical composition,sensory and appearance quality of tobacco leaves were improved to varying degrees.The improvement effect of T2 treatment was the most significant,with increases of 10.36%,7.76%and 7.30%respectively,compared with the CK.The quality evaluation of tobacco leaves was 7.57%higher than that of CK.The combined application of PASP and CTS can effectively increase the soil moisture content,promote the root development of flue-cured tobacco,and improve leaf quality.The optimal treatment(3.0 kg/ha PASP+0.6 kg/ha CTS)alleviated the decline in yield and quality of flue-cured tobacco caused by drought in Bijie.
