种好黄花菜菜农收益丰

山东省枣庄市山亭区桑村镇地处枣庄西北部,周围5公里内没有大型工厂,土壤肥沃,水质优美,是全市典型的无污染区,使无公害黄花菜(又称金针菜)种植获得了得天独厚的地理优势。因为种金针菜比种植其它农作物赚钱多(一般情况下,露地一级黄花菜卖到12元/千克,特级卖到15-16元/千克;大棚早期卖36-38元/千克。),且省时、省力,黄花菜便成了农民们的“香饽饽”。山亭区桑村镇王庙村青年农民、区农广校优秀学员陈家珍栽种的1亩黄花菜,年收益八千余元。现将其栽培技术介绍如下。1繁育壮苗黄花菜主要采用分株繁殖,时间在花蕾采毕后到冬苗萌发前,也可在冬苗枯萎后春苗抽生前的一段时间,但以前者为好。挖苗分苗时应尽量少     

忠诚是一种职场生存的方式

根据英国某权威医学杂志公布的美国军医的一项调查显示,部署在亚洲某地的美国海军陆战士兵中,90%都曾受到过攻击,大多数人都看到过战友阵亡或受伤.由于常期处于紧张状态和时刻面临危险,陆战队员的心理健康受到了严重的损害.该调查表明,1/6的上兵在完成任务后出现了心理问题,这个比例和"越战"时期不相上下.     

中国式思维

去美国不久,我搬进了表哥的公寓,我们的邻居名字叫汉森,表哥和他比较熟。他们最近还一起参加了一个电脑网络培训班,老师让他们去买一本参考书,表哥和汉森跑遍了当地所有的书店都没买到,他们只好去图书馆,每人借了一本。过了两个星期,我发现汉森把这本书全部复印了下来,原书归还了图书馆,表哥借的那本书却还没有还,表哥说,“这书我不打算还了。复印这本书需要大概50美元,而我只用到图书馆办个遗失书的手续,只需交纳10美元。”在一旁的汉森听了这话惊讶地说“:可图书馆里的书是公共资源呀,你怎么可以占为己有?”当地图书馆有规定,如果读者不慎…     

底栖鱼类对水田上覆水中磷素动态的扰动效应

[目的]研究底栖鱼类泥鳅对水田上覆水中磷素动态的扰动效应,探讨生物扰动机制.[方法]基于模拟试验,使用离子色谱法和分光光度法,对比分析上覆水中磷素含量在有/无泥鳅活动时的差异.[结果]扰动组的TP、DTP和PP浓度在试验开始阶段与对照组无显著差异,在试验中、后期显著高于对照(P<0.05).扰动组要的PP/TP高于对照组,扰动组中TP浓度的增加主要是由于PP的增加,扰动组的DIP/DT在试验中、后期显著高于对照(P<0.05).[结论]底栖鱼类对水田上覆水中的磷素产生了扰动作用,增加了水稻生长可利用的的磷素养分. Abstract： [Objective] The research aimed to investigate the bioturbation effects of benthic fish Misgurnus anguillicaudatus on phosphorus dynamic in overlying water of paddy field,as well as to explore the bioturbation mechanism.[Method]Based on simulation experiment,the phosphorus contents in overlying water were analyzed comparatively with and without Misgurnus anguillicaudatus by the using of ion chromatography and spectrophotometry. [Result] The concentrations of total phosphorus (TP),dissolved total phosphorus(DTP)and particular phosphorus(PP) in bioturbation group had no significant differences with those in control group in initial stage of experiment,and became significantly higher than control group in middle and late stages of experiment(P<0.05).The PP/TP ratios in bioturbation group were bigger than those in control group,the increase of TP concentration in bioturbation group was mainly due to the increase of PP.The ratios of dissolved inorganic phosphorus(DIP) to DTP (DIP/DTP) were significantly bigger than those in control group in middle and late stages of experiment (P<0.05). [Conclusion] The benthic fish had bioturbation effects on phosphorus in overlying water of paddy field,which increased the available phosphorus for rice growth.

The cultural politics of the agroecological transition

Scholarly attention to sustainability transitions is rapidly increasing. This article explores how cultural politics constrain agricultural change. Cultural politics, or conflicting values about appropriate types of agriculture, are an underexplored variable influencing whether or not farmers adopt agroecological methods. The research focuses on the environmental, cognitive, and relational mechanisms that influence cultural politics. It analyzes the intersection of mechanisms and cultural politics in an Amazonian agrarian reform settlement of the Brazilian Landless Workers’ Movement (MST). Insights into the factors confounding the agroecological transition are derived from an analysis of longitudinal spatial data derived from historic aerial photographs and remotely sensed images, and ethnographic data from participant observation and semi-structured interviews. Drawing on a political ecology of education perspective, the cultural politics surrounding the agroecological transition are traced to the confluence of the region’s historical usage for cattle ranching (environmental mechanisms), farmer’s conceptions of space (cognitive mechanisms) and the combination of agricultural extension and government credit (relational mechanisms). The MST’s agroecological education initiatives hold the promise to drive the sustainability transition, but are also constrained by these cultural politics and associated mechanisms.     

农民文化需求与新农村文化建设研究

新农村文化建设是新农村建设不可缺少的关键性要素之一。要搞好新农村文化建设,就要关注农民日益增长的精神文化需求,进而繁荣农村文化。当前农民的精神文化需求强烈,对于大众性文化活动、文化场所和文化设施的建设、民间传统文化的浸染和传承等方面的需求日趋高涨。为了有针对性地满足和引导农民群众的文化生活需求,就要注重精神文化产品的开发,加大对农村文化基础设施建设的投入力度,发掘、保护民族民间文化,使优秀传统文化一脉相承,凝聚人心。     

Persistent cultural systems

I have indicated here some features of a kind of entity which I have called a cultural identity system, and I have focused on a variety of this general type-the persistent system. In general terms it is best described as a system of beliefs and sentiments concerning historical events. I suggest using the term "a people" for the human beings who, at any given time, hold beliefs of this kind. These are phenomena with which we have been long familiar, but they have not been systematically studied by any but a few investigators. I have emphasized that a persistent system is a cumulative cultural phenomenon, an open-ended system that defines a course of action for the people believing in it. Such peoples are able to maintain continuity in their experience and their conception of themselves in a wide variety of sociocultural environments. I hold that certain kinds of identifiable conditions give rise to this type of cultural system. These may best be summarized as an oppositional process involving the interactions of individuals in the environment of a state or a similar large-scale organization. The oppositional process frequently produces intense collective consciousness and a high degree of internal solidarity. This is accompanied by a motivation for individuals to continue the kind of experience that is "stored" in the identity system in symbolic form. The persistent identity system is more stable as a cultural structure than are large-scale political organizations. When large-scale states disintegrate, they often appear to decompose into cultural systems of the persistent type. Large-scale organizations also give rise to the kind of environment that can result in the formation of new persistent systems. It is possible that, while being formed, states depend for their impetus on the accumulated energy of persistent peoples. A proposition for consideration is that states tend to dissipate the energy of peoples after transforming that energy into state-level integrations, and then regularly break down in the absence of mechanisms for maintaining human motivations in the large-scale organizations that they generate.

温岭嫁接黄瓜的特征特性与栽培技术

温岭黄瓜(俗称肖村刺瓜),是温岭市本地品种,属蔬菜、水果兼用型,清脆爽口,表面光滑,无瘤刺。该品种在温岭市已有50年的栽培历史,并推广到温州和台州各县市种植。据不完全统计,2005年仅温岭市栽培面积就达73 hm2。近年,温岭市因受枯萎病等土传病害的严重危害,黄瓜产量逐步下降。
