不同类型早熟桃、油桃采后贮藏效果研究

采用不同肉质类型的桃、油桃果实为材料,对采后低温和自发气调包装等对果实硬度、失重和SSC含量等的变化进行了研究,结果表明：(1)不同类型桃、油桃采后果实硬度变化差异较大,常温下24-30和中桃2号果实硬度下降较慢,而中油桃5号、10号较快,在冷库低温条件下,24-30、中油桃5号和中油桃10号两周后硬度出现迅速下降,而曙光和中桃2号在贮藏后即迅速下降,带皮硬度与去皮硬度之间有一定差异,但变化趋势基本一致;(2)MA包装能有效地延缓采后桃、油桃果实硬度的降低,在常温及低温条件下均是如此,不同肉质类型间差异明显,曙光和中桃2号非常敏感,而中油桃10号则不太敏感,即MA包装对其果实硬度降低的延缓没有其它品种明显;(3)采后桃、油桃果实的SSC含量均有一定的降低,低温下该过程较慢,MA包装在常温下有加剧SSC下降的趋势,低温下则不明显,这可能与常温下采后立即进行MA包装不利于“田间热”及呼吸热的及时散发而加剧呼吸有关。(4)桃、油桃采后果实失重明显,低温有助于大大减缓贮藏桃、油桃的失重,常温下1天的失重相当于低温条件下1周的失重,不同类型品种表现有一定差异,常温下曙光失重较慢,而冷库低温条件下中桃2号失重要快于曙光和中油桃10号。     

农产品包装上外文文字的设计和说明

农产品包装上外文文字的编排需要认真推敲,精心布置;要注意整体性,注意主次、大小、位置等的综合处理;针对农产品的特定消费对象,不同形态的包装和表述内容的层次应设计不同的字体;采用光点信息或有颤动感的装饰字体等,具有强烈的现代感。包装上的文字应简洁、真实、生动、适时、易读、易记。外文文字翻译必须要懂得译入语的语言特征,熟悉译入语国家的文化,文字应简练,避免直译或字译;纯天然的农产品在国外很受欢迎,包装上应显著标明。

Computerised data management system for cereal breeding

A program package for wheat breeding was compiled inMartonvásár in 1983 and was used for over 10 years with minormodifications to satisfy breeding requirements. Due to new ideas andadvances made in the field of computer science and othertechnologies the data structure and program package have been redesigned.The chief emphasis in developing the Martonvásár Wheat BreedingSoftware is on the handling of genealogical and observation data and on theclassifications required for well-based selection decisions. The widely-usedWindows 9x/NT operational system, the MSAccess data base-handlingsystem and the Visual Basic 5.0 programming language have been chosenfor this purpose. The subprograms controlling major breeding tasks includethe transfer of the data of the selected lines, with the necessarymodifications, to the data base of the new experimental year, the handlingof new crosses and seed shipment data, the preparation of the field plan,various output (label, fieldbook) and input (manual, online) possibilities anda simple statistical module.

Music work: Traditional Cambodian music and state‐building under the Khmer Rouge

Recent scholarship has opened questions as to the everyday actions of the Khmer Rouge and those living under the regime which led to the Cambodian Genocide. Current work examines the critical cultural geographies of the Khmer Rouge: photography, poetry and music, for example. Music specifically has an interesting underpinning, as it was previously understood to be have been eradicated in the genocide as the standard narrative has us believe. This paper instead investigates the pieces of evidence that exist, which explain the use of music by the Khmer Rouge. I explore the geographies of music beyond the lyrics and look at the transformation and use of music in Cambodia and Democratic Kampuchea. What elements of traditional Khmer music were used during the regime? What modifications occurred to the music of Cambodia during the regime, and how did the Khmer Rouge modify existing Cambodian (and other) music to best fit their desired uses (state‐building and genocide)? This paper goes beyond traditional geographies of music, which rely on lyrical analyses, to bring an ethnomusicological perspective to the work of music and its role in shaping the idea of the Democratic Republic of Kampuchea.

Popular music in a transnational world: the construction of local identities in Singapore

As an area of geographical inquiry, popular music has not been explored to any large extent. Where writings exist, they have been somewhat divorced from recent theoretical and methodological questions that have rejuvenated social and cultural geography. In this paper, I focus on one arena which geographers can develop in their analysis of popular music, namely, the exploration of local influences and global forces in the production of music. In so doing, I wish to explore how local resources intersect with global ones in a process of transculturation. Using the example of English songs by one particular songwriter and artiste whose works are part of the popular music industry mainstream, and that of Mandarin songs of the genre xinyao, I will show that, despite increasing globalising forces, music is still an expression of local/national influences. Indeed, I will argue that globalisation intensifies localisation.
