为探讨关中平原小麦-玉米水分高效利用的栽培技术方式,采用田间定点观测方法,研究秸秆还田+接种蚯蚓处理对土壤含水量的影响。设置CK(对照)、S_(1)(秸秆还田3000 kg·hm^(-2))、S_(2)(秸秆还田6000 kg·hm^(-2))、E(接种蚯蚓)、S_(1)E(秸秆还田3000 kg·hm^(-2)+接种蚯蚓)、S_(2)E(秸秆还田6000 kg·hm^(-2)+接种蚯蚓)共6个处理。结果表明:各处理较CK处理均提高了土壤含水量,S_(1)、S_(2)、E、S_(1)E、S_(2)E处理下土壤含水量分别增加0.21%~27.47%、0.43%~32.85%、1.00%~15.53%、3.25%~36.52%、2.97%~51.24%。CK、S_(1)、S_(2)、E、S_(1)E、S_(2)E处理下土壤含水量分别为15.51%、17.14%、17.66%、16.33%、17.94%、18.91%;S_(2)E处理土壤蓄水保水效果最佳,S_(2)、S_(1)处理次之,E处理效果最差。由小麦扬花期、收获期到玉米抽雄期、收获期,不同处理下0~100 cm土壤含水量整体呈增长趋势,最大均值在玉米收获期(20.60%),最小均值在玉米抽雄期(8.63%)。相比于CK处理,其余处理均扩大了高含水区范围,且接种蚯蚓处理下土壤高含水区范围大于未接种蚯蚓处理。对小麦-玉米生长期土壤含水量影响因素相关分析结果显示,土壤含水量与>0.25 mm的大团聚体、SOC含量、TN含量呈显著正相关关系(P<0.05),与0.053~0.25 mm、<0.053 mm的土壤团聚体、pH值、毛管孔隙呈显著负相关关系(P<0.05)。可见,秸秆还田与蚯蚓活动有利于增加土壤含水量,扩大深层高含水区,提高土壤蓄水能力,进而提高降水利用效率。

传统高温大曲是经自然发酵而生产的,存在微生物群落组成复杂、所需的风味组分及含量难以控制等缺点。为了优化高温大曲微生物菌群结构和提高大曲品质,以小麦为原料,将高温大曲中分离筛选的地衣芽孢杆菌BL44、酿酒酵母SCY62、宛氏拟青霉PV3、微小根毛霉RP1和嗜热子囊菌TC1分别制备成固态菌剂,按不同添加比例构建2种人工合成菌群替代传统母曲(CK)制作高温大曲,并进行实验室酿酒试验分析。高通量测序结果表明,3种大曲的优势真菌属为Lichtheimia,优势细菌属为Bacillus。大曲的理化指标测定结果显示,接种人工合成菌群的高温大曲的液化力和糖化力比CK均有显著提高。气相色谱-质谱分析结果显示,接种人工合成菌群替代传统母曲能显著提高大曲及酒醅中四甲基吡嗪的含量。人工合成菌群1和菌群2接种的大曲中四甲基吡嗪含量分别为31.90 mg/kg和56.73 mg/kg,比CK分别提高了2.80、4.99倍;高温堆积发酵酒醅中人工合成菌群1和菌群2的四甲基吡嗪含量分别为0.76 mg/kg和2.74 mg/kg,比CK分别提高了4.03和14.61倍。以上结果表明,人工合成菌群在定向调控大曲酶活性以及白酒中某些特定风味组分及含量等方面具有潜在的应用价值。

Atomization Inhalation of Terbutaline and Budesonide Efficiently Improved Immunity and Lung Function of AECOPD Patients

Cellular & Molecular Immunology 2008年第4期5卷 287-291页

作者： Guilan xiong lijun Xu Liu Wei Xiaodan Li Department of Respiratory Medicine The First Hospital of Jilin UniversityChangchun 130021 China

Chronic obstructive pulmonary disease （COPD） is a syndrome of chronic progressive airflow limitation as a result of chronic inflammation of the airways and lung parenchyma. COPD patients always have airway hyperreactivity （AHR）, so how to reduce AHR becomes the key purpose of clinical treatment. It is hypothesized that combined inhalation of corticosteroids and β2-agonists can reduce the AHR in COPD. In this study, atomization inhalation of budesonide and terbutaline plus conventional therapies was applied to treat AECOPD （acute exacerbation of chronic obstructive pulmonary disease） patients for two weeks. The results showed that additional inhalation of budesonide and terbutaline could upregulate serum IL-2 levels, the percentages of CD3^＋ T and CD4^＋ T cells, and CD4/CD8 ratio, and decrease eosinophils and serum CRP level more efficiently than conventional treatment in patients with AECOPD. And the lung function of the atomization inhalation group was improved more obviously after the treatment compared with the conventional treatment group. Thus, atomization inhalation of terbutaline and budesonide can control AECOPD effectively, and has wide clinical perspective in controlling and preventing the exacerbation of COPD.
