Brassica has long been of paramount importance to agriculture and human nutrition. Among the Brassica genus, Brassica rapa,the AA diploid, stands out as a prominent representative, valued for its versatility both as a vegetable and oil crop and its genetic proximity to other Brassica species. Economically, B. rapa plays an important role in the food industry, contributing to 12%of the global edible oil supply and 10%of vegetable yield [1].

在人机交互领域,预测躯干肌电信号极具应用潜力。但手部操作、平衡条件等因素会导致躯干肌肉控制模式转换,破坏躯干基于运动信号和肌电信号间的映射关系,因此很难实现高精度躯干肌电预测。为实现对应意图的躯干肌电预测,在设定弯伸腰任务内,测量一组部分椎旁肌肌电信号及运动信号,通过对多维椎旁肌肌电信号的多次两步聚类编码,将其转化为聚类编码号组成的动作向量,作为BiLSTM-CRF算法的输入,实现躯干肌肉动作的分时段标注,进而利用筋骨假人分别校正躯干肌电预测结果。预测校正结果可反映个体特征、躯干和手部动作意图。

为全面准确评估中华绒螯蟹(Eriocheir sinensis)养殖池塘中后期水体浮游植物群落结构特征及其与环境因子的关系,于2022年6—10月逐月监测水质指标,同时采用基于形态学和宏基因组学的人工镜检和高通量测序两种方法分析浮游植物的群落结构特征,探讨浮游植物优势种与环境因子的关系。结果显示,人工镜检鉴定的浮游植物共4门65种,而高通量测序数据分析所得浮游植物共4门1463种,其中人工镜检鉴定的优势种为蓝藻门的水华微囊藻(Microcystis flos-aquae)、细小隐球藻(Aphanocapsa elachista)以及硅藻门的中肋骨条藻(Skeletonema costatum),而高通量测序数据分析所得优势种为蓝藻门的水华束丝藻(Aphanizomenon flos-aquae)、铜绿微囊藻(***)。人工镜检方法计算所得多样性指数普遍低于高通量测序结果。两种方法共同分析得出溶解氧(DO)、叶绿素a(Chl-a)、总氮(TN)和氨氮(NH3-N)是影响浮游植物群落结构的关键环境因子。建议采用人工镜检与高通量测序法相结合的方式分析养殖期间的浮游植物群落结构,以便更全面、准确地评估养殖生态系统中的浮游植物群落结构特征及其与环境因子的关系。

In order to realize intelligent control of flower greenhouse＇ s parameters of atmospheric temperature and humidity, lighting intensity, CO2 concentration and soil water content, it carries out design with ZigBee network, embedded controller and intelligent fuzzy control algorithm as core. With advantages of high precision and stability, the design of sensor circuit mainly employs digital module sensors. In order to save energy, the sensor circuit is controlled by relay switch to work at the proper time. The gateway node is designed by employing high performance 32-digit embedded controller and WinCE6.0 embedded OS is self customized. And embedded SQlite database is realized on WinCE6.0 for effectively managing data. The closed loop control is realized by employing fuzzy control algorithm and the test result shows that the deviation of atmospheric temperature is controlled within ± 0.5° C, the deviation of illumination intensity is controlled within ± 283 LUX, the deviation of CO2 concentration is controlled within ± 24 PPM, the deviation of atmospheric humidity is controlled within ± 13% and that of soil water content is controlled within ± 0.9%, thus all parameters fully meet practical requirements of flower greenhouse.

养殖水体中的微生物群落结构及功能组成对养殖生态系统具有重要作用。为了全面系统评估中华绒螯蟹(Eriocheirsinensis)养殖中后期水体微生物群落结构和功能组成,于2022年6―10月逐月监测上海市崇明区中华绒螯蟹养殖池塘内水质指标,同时基于宏基因组学技术分析了养殖期内水体中微生物物种组成及功能结构特征,并探讨了二者与环境因子的关系。结果显示,该养殖池塘在养殖中后期主要超标水质指标为p H、高锰酸盐指数、总磷和总氮。在养殖期水体中,6―8月的微生物群落多样性以及7―8月的微生物群落丰富度处于较高水平,优势门为细菌中的变形菌门(Proteobacteria)、拟杆菌门(Bacteroidetes)、放线菌门(Actinobacteria)、疣微菌门(Verrucomicrobia)、蓝细菌门(Cyanobacteria)和病毒中的尾噬菌体门(Uroviricota),而在属水平上,丰度占比前10的优势属在多组之间均存在显著差异,如7月蓝藻门微囊藻属(Microcystis)细菌和8―10月的有尾噬菌体目(unclassified_o_Caudovirales)病毒丰度明显高于其他月份。微生物的主要功能为代谢功能包括能量代谢、全局和概览图、氨基酸代谢等,不同月份的功能组成存在显著差异,尤其是6―7月代谢途径丰度明显高于8―10月,而优势细菌变形菌门、放线菌门和拟杆菌门是上述功能的主要贡献者。环境因子对微生物群落结构和功能组成的影响趋势一致,叶绿素a和pH是影响最显著的环境因子,溶解氧、总磷的影响作用稍弱。在养殖水体中,丰度占比较大的致病菌为肠道沙门氏菌(Salmonella enterica)、爱德华氏菌(Edwardsiella ictaluri)和金黄色葡萄球菌(Staphylococcus aureus)。研究结果可为中华绒螯蟹养殖池塘水体微生物群落结构和功能组成研究提供基础数据,并可为养殖水质调控及生态系统构建提供理论依据。
