鲁西南短季棉大豆不同间作模式产量及经济效益分析

为有效解决传统棉作模式存在的作物间茬口不顺、环节间衔接不畅、产业间技术协同不强等问题,探索适合鲁西南短季棉的栽培模式,以大豆品种齐黄34和棉花品种鲁棉2387为供试材料,设计单作棉花、单作大豆和棉豆间作(二四式、四四式、四六式)5个处理,研究了棉豆间作模式对大豆和棉花生育进程、农艺性状、产量及经济效益等的影响。结果表明:二四式棉豆间作的棉花吐絮早2~5 d,吐絮畅,而且铃大,衣分高,单株结铃增多1.0~2.5个,烂铃较少,2行均为边行,通风透光较好,边行优势明显;二四式棉豆间作的每666.7 m^(2)经济效益最高(625.6元),分别比四四式棉豆间作、四六式棉豆间作、单作大豆、单作棉花高81.3元、106.0元、294.2元、245.1元。综上,二四式棉豆间作模式的复合群体空间分布合理,较为适于鲁西南地区。

Effectiveness of Xiaoyao capsule(逍遥丸)on sleep disorders and mood disturbance in patients in recovery from coronavirus disease 2019:a randomized controlled trial

OBJECTIVE:To study the efficacy of Xiaoyao capsule(逍遥丸)in improving the clinical symptoms of sleep and mood disorders during recovery from coronavirus disease 2019(COVID-19).METHODS:The study cohort comprised 200 patients with sleep and mood disorders during recovery from COVID-19.Patients were randomized into the control group and the experimental group in a 1:1 ratio by blocked randomization.The patients received either Xiaoyao capsule(experimental group)or a placebo Xiaoyao capsule(control group)for 2 weeks.The improvements in the Traditional Chinese Medicine(TCM)syndrome scales,total effective rates,and disappearance rates of irritability,anxiety,and poor sleep were compared between the two groups.RESULTS:The TCM syndrome pattern scales,total effective rates,and disappearance rates of irritability,anxiety,and poor sleep did not significantly differ between the experimental group versus the control group in the full analysis set and the per protocol set after 1 and 2 weeks of treatment(P>0.05).CONCLUSIONS:Xiaoyao capsule do not significantly improve the clinical symptoms of sleep and mood disorders in patients in recovery from COVID-19.
