【背景】异养氨氧化细菌(heterotrophic ammonia-oxidizing bacteria,haoB)通过增加叶片细胞分裂素含量促进多花黑麦草的再生,但其促进植物再生的具体机制尚未探明。【目的】揭示haoB调控细胞分裂素的合成促进多花黑麦草再生的机制。【方法】以一株haoB菌株(S2_8_1)为试验菌株,盆栽多花黑麦草作为植物材料。试验处理设计包括:常规供水(TA);添加空白富集培养基(TB);添加硝化抑制剂3,4-二甲基吡唑磷酸盐(3,4-dimethylpyrazole phosphate,DMPP)(TN1);添加DMPP和20 mmol/L的NO_(3)^(−)-N(TN2);添加DMPP和30 mmol/L的NO3−-N(TN3);添加DMPP和40 mmol/L的NO_(3)^(−)-N(TN4);接种菌株S2_8_1(TI)。【结果】30−40 mmol/L NO_(3)^(−)-N对提高叶片细胞分裂素含量和根向叶片传递效果最好,从而促进叶片再生。在根际土壤硝化作用诱导的细胞分裂素增加达到最大限度时,接种菌株S2_8_1进一步增加了根中细胞分裂素的合成,提高了叶片中细胞分裂素的浓度。所测试的haoB菌株S2_8_1通过双重作用显著提高了叶片细胞分裂素的浓度,促进了多花黑麦草再生。【结论】本研究揭示了haoB菌株在根际发挥双重作用促进植物生长的机制,为提高牧草产量和农业可持续发展提供直接应用价值。

为满足新一代航空发动机的高推重比需求,提出一种支板与混合器一体化加力燃烧室方案,采用数值仿真方法,对比分析进口马赫数Ma (0.3~0.45),涵道比B (0.25~0.37)和不同飞行高度H(0~20 km)对加力燃烧室热态流场特性的影响。研究表明:在研究参数范围内,进口马赫数增大,壁式稳定器回流区及下游区域的燃气温度受到影响,区域内燃气温度逐渐升高,沿程径向温度不均匀性逐渐减小,总压损失增大,燃烧效率逐渐下降,但出口燃烧效率仍基本高于0.90;进口涵道比B增大,壁式稳定器下游及中心锥轴线位置的燃气温度开始下降,沿程燃气总压损失增大,燃烧效率随之升高,B从0.25增大至0.28时,燃烧效率提升较大,继续增大涵道比,燃烧效率提升较少;随着飞行高度升高,整体燃烧效率逐渐下降,在0 km和11 km飞行高度之间燃烧效率下降较少,而在20 km飞行高度时燃烧效率下降相对明显。
