微生物菌肥与化学肥料配施对盈江省藤生长的影响

为了解不同肥料种类及其施肥量对盈江省藤生长的影响,采用L₉(3⁴)正交试验设计对其2年生幼林进行连续3年的微生物菌肥与复合肥和磷肥配施试验。结果表明,3年中不同因素的各水平组合间苗木的地径、株高、叶片数和冠幅均呈现极显著的差异(P<0.01)。施用复合肥和磷肥总体呈现显著(P<0.05)或极显著(P<0.01)地抑制盈江省藤生长的现象。不同肥料配施试验组合的地径、株高和叶片数均大于对照的相应指标。试验期间,单施微生物菌肥0.3~0.6 g/株即可满足盈江省藤生长的需求。

基因型和环境对小麦烘烤品质的影响

利用１２个小麦品种在５个地点的试验结果，分析了品种、环境以及品种与环境的互作对小麦烘烤品质的影响，结果表明：品种、环境以及品种与环境的互作对小麦烘烤品质都有显著影响，品种和地点的互作效应在同一品种不同地点间是不同的，在较差的环境下，也有表现好的品种。不同环境下，烘烤品质指标的变化大于籽粒蛋白质含量的变化，小麦品种品质的评价，不仅应考虑其蛋白质含量在不同地点之间的变化，更重要的是研究最终加工品质的变

可控硅移相单异步电动机的研究

由于单相异步电动机本身产生的磁场是脉振磁场,没有起动转矩,因此需要用一些辅助方法使其产生旋转磁场而得到起动转矩。以往采用的方法有:电容移相、电阻移相、罩极移相等辅助起动方法。本文介绍一种用双向可控硅移相的单相异步电动机起动方法,并用富里叶级数及双旋转磁场理论对系统中单相异步电动机输出转矩M随可控硅控制角α变化的规律进行了分析,求出了输出转矩M随α变化的函数关系,给出了出现最大转矩时的控制角α_M。最后,用实测值和理论值进行了比较,对理论值和实测值间的误差原因进行了分析。     

Adaptability of various models of the water production function for rice in Jilin Province,China

The existing irrigation schedule of most rice-growing areas in Jilin Province is not in full compliance with the Water Requirements Law of the rice; these discrepancies affect the yield of rice to some extent. Thus, research on rice water regulations and selection of an appropriate water production function model (WPFM) is very important. In this study, according to the water demand characteristics of rice, we used drought treatments separately during the tillering, jointing booting, flowering, and milky stages. Evapotranspiration and yield data were obtained using a test pit experiment and production measurements in 2011 and 2012, respectively. Five commonly used WPFMs (the Jensen, Blank, Minhas, Stewart, and Singh model) were selected for this study, and the water sensitivity index of each model was calculated based on the evapotranspiration, yield, and the model equations. The Jensen model was found to be the most suitable WPFM for this region; furthermore, a mathematical relationship between the water sensitivity index and days after rice planting was established. These results have important theoretical and practical implications for guidelines regarding rice irrigation in Jilin Province.     

Limited awareness of animal influenza prevention and control among Dai Lue smallholder farmers in Southwest China

Awareness of animal influenza and its prevention and control is important for ensuring livestock health, production and welfare. In China, a country stereotyped as a major source of emerging zoonotic infectious diseases, research on the public understanding of animal influenza is limited to the Han, the main ethnic group. The present qualitative study in Southwest China investigated awareness of animal influenza among the Dai, an ethnic minority. The participants (15 men and 10 women, ages 18–83) were smallholder farmers of pigs and poultry in rural areas of Jinghong, Xishuangbanna, Yunnan Province. A mixture of interviews and group discussions took place in homes and villages. The participants were asked about their knowledge of avian influenza (H7N9), swine influenza (H1N1), precautions taken to protect against influenza, procedures when animals were sick and perceived risk of animal influenza. The data were analysed following coding and thematic analysis. The findings demonstrated a limited understanding of animal health and welfare among participants. Specifically, they were largely unaware of animal influenza (H7N9, H1N1) including its causes, symptoms, prevention and treatment. The farmers were also uninformed of the risks they faced and unknowingly engaged in behaviours which increased direct or indirect exposure to infected animals, a risk factor for human infection. They also reported poor usage of veterinary services. In order to guarantee the health, welfare and production of their livestock, immediate action is needed to enable Dai smallholder farmers to prevent and respond to animal influenza effectively and timely.     

沼液浸种对黑麦草种子发芽的影响

为了研究沼液浸种对黑麦草种子发芽的影响,设置4个浓度沼液分别浸泡黑麦草种子,分析种子各项发芽指标的变化。结果表明:各处理均能正常发芽,黑麦草种子的发芽率和发芽势等4项发芽指标均随着浸种沼液浓度的增加呈现先上升后下降的趋势,以75%沼液浓度浸种效果最优,但沼液浸种对发芽率和发芽势的影响要高于苗高和根长。综合分析认为利用沼液浸泡黑麦草种子是提高其生产性能的有力措施,适宜在生产中推广利用。
