徐学明 《中国农机化学报》2021,42(11):180

从危机沟通的渠道、危机沟通的具体策略、危机沟通的后续行动三个方面,为中国农机企业的危机沟通提供可行建议。以形象修护理论为基础,结合移动互联网环境传播特点以及中国农业机械化发展的实际情况,分析新浪新闻手机客户端、今日头条手机客户端上的两条农机质量纠纷视频。推荐农机企业使用的8条具体策略包括:否认事件不实部分;表明事件的意外属性;阐明自身出发点;阐明自己的贡献及所做出的努力;提出物质补偿;提出改进措施;承担有错部分;主动向用户征询意见。提出危机沟通应在线上、线下两种渠道进行,危机沟通应与具体行动相结合。  相似文献

饲粮精料水平和蛋氨酸铬添加剂量对舍饲滩羊生长性能、屠宰性能、肉品质和脂肪沉积的影响     

金亚东  贾柔  周玉香  马青 《动物营养学报》2021,33(2)

本试验旨在探究饲粮精料水平和蛋氨酸铬(Cr-Met)添加剂量对舍饲滩羊生长性能、屠宰性能、肉品质和脂肪沉积的影响。采用2×3双因素试验设计,2个因素分别为饲粮精料水平和Cr-Met添加剂量,其中饲粮精料水平分别设为35%(低精料饲粮,饲粮精粗比为35∶65)和55%(高精料饲粮,饲粮精粗比为55∶45),Cr-Met添加剂量分别设为0、0.75和1.50 g/(d·只)。将60只雄性滩羊羔羊[平均体重为(21±1)kg]随机分配到6个试验组,每组10只。试验期为80 d,其中预试期15 d,正试期65 d。结果显示:1)与低精料饲粮组相比,高精料饲粮组滩羊的平均日增重、屠宰率、背膘厚度、肌内脂肪含量和后腿肉比重显著增加(P<0.05),但料重比与肌肉蒸煮损失、剪切力、pH、亮度(L*)值、红度(a*)值和黄度(b*)值则显著降低(P<0.05)。2)低精料饲粮组滩羊背膘厚度、皮下脂肪厚度、肌内脂肪含量和后腿肉比重随Cr-Met添加剂量的增加而线性降低(P<0.05),但肌肉pH则线性升高(P<0.05)。3)高精料饲粮组滩羊肋肉比重、腰肉比重以及肌肉剪切力和pH随Cr-Met添加剂量的增加而线性升高(P<0.05),而肌内脂肪含量和肌肉a*值则线性降低(P<0.05)。综合本试验测定指标,建议在滩羊养殖中选择精粗比为55∶45的高精料饲粮,Cr-Met的适宜添加剂量为1.50 g/(d·只),且不建议在精粗比为35∶65的低精料饲粮中添加Cr-Met。  相似文献

Exogenous application of allelopathic water extracts helps improving tolerance against terminal heat and drought stresses in bread wheat (Triticum aestivum L. Em. Thell.)          下载免费PDF全文

M. Farooq  F. Nadeem  M. Y. Arfat  M. Nabeel  S. Musadaq  S. A. Cheema  A. Nawaz 《Journal of Agronomy and Crop Science》2018,204(3):298-312

The allelopathic water extracts (AWEs) may help improve the tolerance of crop plants against abiotic stresses owing to the presence of the secondary metabolites (i.e., allelochemicals). We conducted four independent experiments to evaluate the influence of exogenous application of AWEs (applied through seed priming or foliage spray) in improving the terminal heat and drought tolerance in bread wheat. In all the experiments, two wheat cultivars, viz. Mairaj‐2008 (drought and heat tolerant) and Faisalabad‐2008 (drought and heat sensitive), were raised in pots. Both wheat cultivars were raised under ambient conditions in the wire house till leaf boot stage (booting) by maintaining the pots at 75% water‐holding capacity (WHC). Then, managed drought and heat stresses were imposed by maintaining the pots at 35% WHC, or shifting the pots inside the glass canopies (at 75% WHC), at booting, anthesis and the grain filling stages. Drought stress reduced the grain yield of wheat by 39%–49%. Foliar application of AWEs improved the grain yield of wheat by 26%–31%, while seed priming with AWEs improved the grain yield by 18%–26%, respectively, than drought stress. Terminal heat stress reduced the grain yield of wheat by 38%. Seed priming with AWEs improved the grain yield by 21%–27%; while foliar application of AWEs improved the grain yield by 25%–29% than the heat stress treatment. In conclusion, the exogenous application of AWEs improved the stay green, accumulation of proline, soluble phenolics and glycine betaine, which helped to stabilize the biological membranes and improved the tolerance against terminal drought and heat stresses.  相似文献   

Identification and quantification of anthocyanins in different coloured cultivars of ornamental kale (Brassica oleracea L. var. acephala DC)

Anthocyanins are responsible for the colour of many fruits, vegetables, flowers, and coloured-leaved trees. Ornamental kale (Brassica oleracea L. var. acephala DC) is widely cultivated for its colourful inner leaves. To investigate the relationship between the degree of colouration and anthocyanin distribution, content, and composition in ornamental kale, the authors studied the pigment characteristics of five cultivars with different coloured leaves (white, pink, red, purple, and purple-black). Microscopy observation, spectrophotometer, and high-performance liquid chromatography-mass spectrometry (HPLC-MS) analysis of fresh inner leaves revealed that pink, red, and purple colourations were associated with high levels of anthocyanin, while purple-black was the result of the combination of anthocyanins and chlorophyll. In the coloured cultivars, anthocyanins were abundant mainly in the first and second cell layers below the epidermis in both the hypocotyls and inner leaves. No anthocyanin was found in the white-leaved phenotype cultivar. Anthocyanin content increased as leaf colour deepened from pink, red, to purple cultivars, which had little chlorophyll and carotenoid. The authors identified eight anthocyanins in the four coloured cultivars, including one non-acylated, four monoacylated, and three diacylated cyanidin glycosides. Cyanidin-3-(sinapoyl)(feruloyl)-diglucoside-5-glucoside was the most abundant anthocyanin in the four coloured cultivars followed by cyanidin-3-(sinapoyl)-diglucoside-5-glucoside. The analysis of anthocyanin accumulation characterisation provides important information on evaluating colouration patterns in coloured plants, and will be helpful for breeding desired leaf colours in ornamental kale.  相似文献

花生品质性状的稳定性和基因型-环境互作研究，可为花生品质育种及不同生态区域花生品种的选择提供参考依据。本研究利用GGE-biplot工具，对我国黄淮海花生主产区16个花生品种两年间的品质性状进行了综合分析，包括含油量、油酸、亚油酸、棕榈酸和蛋白质含量等。结果显示，5个品质性状均有较高的GGE总变异值（主成分因素PC1和PC2变异的总和），变幅在61.5%-79.9%之间，以含油量的GGE变异值最低，为61.5%，油酸含量的GGE变异值最高，为79.9%。16个花生品种2年间部分品质性状表现较为一致，其中濮花9519的含油量表型值波动最小，山花9号的亚油酸含量表型值波动最小，开农49是油酸含量表型值最为稳定的品种，天府23号是棕榈酸含量和蛋白质含量表型值最为稳定的品种。初步明确了徐州和濮阳分别适合高油花生和高油酸花生种植，确定了不同生态类型试点下较适合种植的品种，为花生品种推广应用提供了参考。  相似文献
