摘要
为探究不同有机肥与无机肥比配对南阳烟区烟草上部叶品质、改善土壤碳氮结构的作用,以烤烟品种云烟87为试验材料,以沼渣和芝麻饼肥为有机氮源,根据有机氮∶无机氮的不同配比设置6个处理[T1(0∶10,纯化肥)、T2(1∶9)、T3(2∶8)、T4(3∶7)、T5(4∶6)、T6(5∶5)],对相应的烟叶和土壤样品进行检测分析。结果表明,与T1处理相比,施用沼渣有机肥和芝麻饼肥处理的烟草叶片大小、单叶重、钾氯比、淀粉含量、产值、香气总量等均显著提升,其中T4处理烟叶的叶长、叶宽、钾离子含量、淀粉含量、均价、产值、香气总量分别较T1处理提升了9.23%、10.49%、21.79%、31.91%、21.31%、26.57%、19.92%。与T1处理相比,施用有机肥处理的土壤有机碳含量、土壤碳氮比及微生物量碳、氮含量均明显提高。在南阳烟区按照有机氮∶无机氮配比为3∶7施用沼渣有机肥和芝麻饼肥能够有效提升烟草上部叶质量、耐熟性及成熟度,并改善土壤碳氮比。
To explore the effect of different organic fertilizer and inorganic fertilizer application ratio on tobacco upper leaf quality and soil carbon and nitrogen structure in Nanyang tobacco area,taking flue-cured tobacco variety Yunyan 87 as the test material,biogas residue and sesame cake fertilizer were used as the organic nitrogen sources,and 6 treatments were set according to different ratios of organic nitrogen to inorganic nitrogen[T1(0∶10,purified fertilizer),T2(1∶9),T3(2∶8),T4(3∶7),T5(4∶6),T6(5∶5)]to analyzy the corresponding tobacco leaves and soil samples were analyzed.The results showed that compared with T1 treatment,the leaf size,single leaf weight,ratio of potassium to chloride,starch content,output value,and total aroma of the treatments with biogas residue and sesame cake fertilizer significantly increased.Among them,the leaf length,leaf width,potassium ion content,starch content,average price,output value,and total aroma of T4 treatment were increased by 9.23%,10.49%,21.79%,31.91%,21.31%,26.57%,and 17.86%compared with T1 treatment,respectively.Compared with T1 treatment,the soil organic carbon content,soil carbon-nitrogen ratio,microbial biomass carbon and nitrogen content were significantly increased in the treatments with organic fertilizer.In Nanyang tobacco area,applying biogas residue and sesame cake fertilizer according to the organic nitrogen∶inorganic nitrogen ratio of 3∶7 could effectively improve the quality,mature tolerance and maturity of upper tobacco leaves,and improve soil carbon-nitrogen ratio.
