摘要:

本研究分析新型生物有机肥在烟草种植上的应用效果,旨在阐明其对烤烟植株生长发育的调控作用。通过盆栽试验,设置5个处理[仅施烟草复合肥(CK)、施烟草复合肥和腐熟有机肥(O)、施烟草复合肥和微生物菌剂(M)、施烟草复合肥和普通生物有机肥(BOF1)、施烟草复合肥和新型生物有机肥(BOF2)],分析其对烤烟旺长期和成熟初期农艺性状、根系形态、叶绿素含量及生物量的影响,并通过相关性分析揭示根系发育与地上部生长的关联。结果表明,在旺长期,2个生物有机肥处理的烤烟茎粗、最大叶长、最大叶宽和SPAD值均显著高于其余处理(P<0.05);各处理根长表现为BOF2>BOF1>O>M>CK,根表面积表现为BOF2>O>BOF1>CK>M(P<0.05);BOF2处理的烤烟鲜重总量、地上部干重和干重总量均显著高于其他处理。在成熟初期,BOF2处理烤烟的株高、茎粗、最大叶宽和SPAD值均达最大值,其地上部鲜重、干重亦为最高,较CK提高44.95%、61.31%。相关性分析表明,烤烟根系形态与最大叶长、有效叶数、地上部鲜重等多个地上部指标具有显著相关性。新型生物有机肥较其余处理显著提升了烤烟多项农艺性状,提高了烤烟早期根系生长速率,增强了烤烟地上部和地下部干物质积累,促进了烤烟生长发育。

Abstract:

This study aims to analyze the effects of a novel biological organic fertilizer on tobacco cultivation, specifically its regulatory impact on the growth and development of flue-cured tobacco plants. A pot experiment was conducted to study the impact of five treatments on root indicators, agronomic traits, and biomass of flue-cured tobacco. The treatments included tobacco-specific compound base fertilizer (CK), tobacco-specific compound base fertilizer with composted organic fertilizer (O), tobacco-specific compound base fertilizer with microbial agents (M), tobacco-specific compound base fertilizer with ordinary microbial fertilizer (BOF1) and tobacco-specific compound base fertilizer with novel biological organic fertilizer (BOF2). At vigorous growth stage, the stem diameter, maximum leaf length, maximum leaf width and SPAD value of the two bio-organic fertilizer treatments were significantly higher than those of the other treatments (P<0.05). The root length of each treatment showed the order of BOF2>BOF1>O>M>CK, the order of root surface area was BOF2>O>BOF1>CK>M (P<0.05). The total fresh weight, shoot dry weight and total dry weight of flue-cured tobacco in BOF2 treatment were significantly higher than those in other treatments. At the early maturity stage, the plant height, stem diameter, maximum leaf width and SPAD value of BOF2 treatment reached the maximum value, and the fresh and dry weights of aerial parts were also the highest, which were 44.95% and 61.31% higher than those of CK. The correlation analysis showed that the root morphology of flue-cured tobacco was significantly correlated with the maximum leaf length, the number of effective leaves and the fresh weight of aboveground parts. Compared with the other treatments, the new bio-organic fertilizer significantly improved many agronomic traits of flue-cured tobacco, increased the growth rate of root system at early stage, enhanced the dry matter accumulation of aboveground and underground parts, and promoted the growth and development of flue-cured tobacco.
