棉花叶枝数与种植密度对单株结铃数的影响

为了探明棉花叶枝数和密度对单株结铃的影响规律,试验设置5种留叶枝方式：不留叶枝（CK）、留1叶枝、留2叶枝、留3叶枝、留全部叶枝;5个种植密度（万株·hm^－2）：2.25,3.00,3.75,4.50,5.25。研究结果表明：在同一密度条件下,随叶枝的增多,单株铃数增加;留1叶枝单株铃数较对照增加10%左右,留2、3叶枝单株铃数较对照增加15%左右,保留全部叶枝较对照增加25%左右。在同一叶枝处理下,随密度的增加,单株铃数减少;密度每增加7500株·hm^－2,5种留叶枝方式的单株结铃分别减少2.60个、3.04个、3.06个、3.44个和3.71个。总铃数随叶枝和密度的增加而增加,当总成铃为88.24万个·hm^－2时产量最高。     

Explaining urban governance in the midst of political transformation: The city of Macao

This paper takes a close look at the urban governance and political culture of Macao, the world largest casino city. Macao has experienced spectacular economic growth since gaming liberalisation in 2002 and China's Free Individual Travel scheme launched in 2003. However, the booming gaming sector has crowded out other sectors of Macao. It has not only made the city's economy mono‐structured and consequently extremely vulnerable to external shocks and fluctuations but also induced serious social divisions and political controversies within the local community. By tracing the root cause of the ongoing dilemma and crisis in the mode of governance, the dynamic relationships between formal and informal institutions, consensus politics and the social group culture are intensively discussed in a historical context. In fact, the sustainable development of the former Portuguese colony has largely been hindered by its residents' passive attitudes toward political communication, non‐transparent urban governance, the absence of a middle class and the dominance of pro‐establishment social groups.

不同耕作模式下水稻产量与器官多要素响应的比较研究

认识和理解水稻产量影响要素是实现水稻高产稳产的关键。选取冬水田、垄作免耕和常规水旱轮作3种处理,采用相关分析、主成分分析与主成分多元线性回归3种方法对水稻产量与成熟期根、茎、叶、籽粒碳同位素组成,根系特征以及养分的响应关系进行比较与综合分析。结果表明不同耕作模式下垄作免耕的水稻产量最高,根、茎、叶、籽粒的碳同位素组成与水稻产量有极显著的负相关关系(P0.01);主成分分析提取的6个主成分累计贡献率超过80%;主成分多元线性回归模型能够解释冬水田、垄作免耕和常规水旱轮作水稻产量67%、73%和97%的变异;与常规水旱轮作相比,冬水田和垄作免耕水稻产量与碳同位素组成及磷的关系更密切。该研究表明,垄作免耕具有较好的推广应用价值。     

喷施非嗜食植物汁液对温室白粉虱的影响

温室白粉虱取食广泛,寄主繁多,但它也有非嗜食植物。非嗜食植物对温室白粉虱可能有很好的控制作用。研究了4种植物的汁液对温室白粉虱的影响,结果表明,供试植物的汁液对温室白粉虱都有很好的控制作用,使温室白粉虱落卵量减少65%以上。非嗜食植物次生物质在温室白粉虱的控制中会有良好的前景。

优质强筋小麦龙麦30配粉特性的研究

以强筋小麦龙麦30为主粉与中筋小麦克丰6号等3个品种进行不同比例配粉研究其面包烘焙品质的影响。试验结果表明,龙麦30与面筋含量高,面团拉伸阻力适中,延伸性长的克丰6号品种搭配,配粉以60%∶40%比例的湿面筋含量和延伸性显著增加,面团流变学特性加以改善,蛋白质数量与质量指标较为均衡,面包体积增大,面包芯部结构、平滑度等指标均得到提高,面包烘焙品质为最佳。     

杏鲍菇形态特征获取的图像分割算法

食用菌工厂化生产中,菇房环境对食用菌生长的影响很大,由工人根据食用菌的形态特征来判断菇房环境是否适宜,会由于个体主观差异或人为因素不能及时判断,造成菇房环境调节滞后,影响了食用菌的产量和质量。以杏鲍菇为研究对象,提出了获取杏鲍菇形态特征的蚁群算法改进的模糊C均值(FCM)聚类分割算法,该算法能够针对杏鲍菇生产中获取的图像,进行有效地分割,从而满足自动获取杏鲍菇形态特征的需要。
