储粮环流熏蒸系统调质通风试验

粮食在储藏期间和通风过程中,容易造成水分减量,安全水分以内的储粮水分下降,不仅造成储粮数量损失,而且水分过低不利于储粮品质保鲜,影响其加工品质,整精米率降低。因此,为了减少储粮水分降低带来的粮食损失,改善稻谷加工品质,对储粮进行通风调质势在必行。     

高大平房仓库存小麦整仓调质试验

粮食在保管过程中，为确保储粮安全。采取机械通风或自然通风方式降低粮食温度、水分，同时粮粒本身在生命活动过程中，消耗干物质，造成粮食含水量降低、数量减少，影响到粮食的加工工艺品质和企业的经济效益，给企业造成无形的损失。为此，中央储备粮临沂直属库对即将出库的62#仓，利用人工增湿设备进行调质，实现出库粮食水分达到或基本接近国家规定标准，效果比较理想，经济效益可观。同时大大改善了粮食的加工工艺品质，取得良好的社会效益。     

巧用轴流风机、环流风机通风降温

机械通风是常用的一种储粮技术，在安全储粮中起重要任用。秋冬两季是通风降温、冻仓的好时机。在过去通风降温时，多采用自然通风、离心风机通风降温。使用离心风机虽然降温迅速，但成本高、易造成储粮水分减量，影响出库数量，给单位造成一定的经济损失。在实际操作中，我们利用新建高大平房仓所安装的轴流风机、环流风机进行通风降温，不仅成本低、易控制储粮水分减量，而且方法简单易行、效果明显。     

稻谷增湿调质通风的效率与安全

通过合理安排通风方式,使增湿、缓释储存、通风平衡等3个过程在粮堆不同部位同步进行,节约通风时间,并根据环境条件适时调整造雾量,以达到最佳气化效果,提高增湿调质通风的效率;通风过程中及时掌握最高水分的动态,根据最高水分确定结束增湿调质通风的时机,确保增湿调质通风的安全。     

储粮保量通风过程中的死角处理试验

储粮保量通风是为了降低储粮机械通风过程中的水分减量而进行的一种机械通风方式.保量风机风速低、风量小,在通风过程中,由于粮堆内杂质聚集、通风系统漏风、堵风等原因在粮堆内容易形成通风死角.     

机械通风储粮技术在高水分玉米安全储藏中的研究与应用

近年来大批高水分玉米进入市场，给安全储粮带来很多隐患。利用机械通风技术达到降温降水、调质的目的，使散装高水分玉米在房式仓中安全度夏，安全储藏，既省时、省力、降低费用、减少损失，又提高了企业效益。山东鲁中国家粮食储备库通过机械通风储粮新技术对高大平房仓散装储藏高水分玉米(14．7％)安全度夏问题进行了应用性生产试验。     

稻谷通风技术系列报道

三 稻谷增湿调质通风技术 我国是世界上稻谷生产大国。由于早籼稻收获时期正值高温季节,因而含水量普遍较低,一般为11％左右;同时,近年来个别地区,运用机械通风储粮不够合理,在低湿度条件下运转致使稻谷水分值降得更低。这种水分值对稻谷的安全储藏显然有益,但对稻谷加工来说降低了食用品质,促使碎米率增大,出米率降低,精度下降,口感较差,机械磨损加块,加工成本增大,从而降低了企业经济效益。     

小麦调质通风应用研究

小麦在储藏管理工作中,由于水分的下降和自然损耗等原因,导致出库时造成不同程度的粮食质量损失。对散装小麦仓,在确保粮食安全的前提下,就减少粮食质量损失,采用不同的调质通风方法进行对比试验研究。结果表明：对散装小麦进行调质通风,能均匀地增加粮食水分含量,可以达到保质、增效的目的。     

高大平房仓轴流风机通风降温试验

粮食在储藏期间,在冬季利用离心风机机械通风降温造成的水分减量是粮食保管损耗的主要因素之一,并且单位能耗较高。为了降低水分损耗和节能减排,采用小功率轴流风机进行冬季降温通风蓄冷试验。试验表明,利用仓房轴流风机进行缓速通风,既达到了通风降温的目的,又降低了储粮损耗和通风费用,经济效益明显。

Similarities and dissimilarities between the EU agricultural and rural development model and Romanian agriculture. Challenges and perspectives

The main aims of this study are to highlight the differences and the similarities between the European model of agricultural and rural development, and the state of play in the Romanian agricultural sector. Statistically speaking, the agricultural sector's indicators of the past two decades place Romania outside the family picture of the EU countries, with very slight resemblances, and very strong discrepancies between their economic, technical, and institutional characteristics. At present, competition-wise, farming and farmers in Romania are still strongly disfavoured in relation to their competitors in the old EU Member States. In Romania, the economic and institutional mechanisms have most often been devised to the disadvantage of agricultural production, by claiming that subsistence farming would be the sustainable way, and by channelling the added value to other sectors. An option to continue the agricultural policies of the past decades and to abandon the national support lent to agriculture would be particularly risky through its unpredictable and incalculable social and economic effects.     

Land use planning and health and well-being

This paper is concerned with the relationship between the planning of settlements and health. It gives a brief introduction to the issues before summarising the evidence in relation to a range of topics, concluding with some more speculative thoughts on likely future findings.Modern planning was invented in response to inhumane living conditions in 19th century cities. But in the last century the connection was lost. Only now, with concerns over climate change and obesity, is there beginning to be the realisation that the physical environment is an important determinant of health.The paper uses a particular model of this relationship based on eco-system and health determinants theories to structure the review of evidence. The review covers: lifestyle choices in relation to physical activity and diet, mental well-being and community, the local economy and income, health inequalities and strategic land use transport planning, pollution and urban form, and finally impacts on global ecology.There is now a growing consensus that while personal factors are critical in determining health, the urban environment exacerbates or mitigates health and well-being outcomes.The level of active travel (walking and cycling) and outdoor recreational activity is strongly affected by accessibility to local facilities. Access to green, natural environments, and to local social networks, are factors in mental well-being. The wider sub-regional pattern of housing, economic development, land use and transport is a determinant of social exclusion and therefore health inequalities. It also affects health-damaging pollution, adaptability in the face of climate change and the level of carbon dioxide emissions.We have literally been building unhealthy conditions into many of our towns and cities. But comparisons with the best cities in Europe indicate that it is possible to reverse the less desirable trends. Success depends, however, on more radical policies of local authority control over land and finance than any political party has yet advocated. It also requires collaboration between the full range of powerful public and private organizations that influence the built environment.Future research is likely to further strengthen these conclusions. It will become much more obvious that planning for health and well-being is not only the NHS, but about creating a health-promoting physical, social and economic environment.     

Mix and sequencing of economywide and agricultural reforms: Chile and New Zealand

Once committed to economywide and sectoral reforms – stabilization, structural adjustment, and trade liberalization – and companion reforms of institutions, how does government best proceed? With what reforms in response to initial conditions, and in what mix, sequence, strength, and speed? This study examines what factors were most critical to success during transition in two early reformers. The economies of Chile and New Zealand have undergone seismic reforms, starting in the mid-1970s and 1980s, respectively. Comparative analysis of their reforms look at the prior conditions that induced drastic action and the policy choices made in each country. Though similar in many respects, differences in initial economic conditions and implementation led to dissimilar, even contrary results. For Chile, the outcome was a vigorous, recharged economy and agricultural sector; for New Zealand, the economy and the sector are lagging still. How policy choice and implementation, as well as simultaneity of reforms, affected the outcomes is the major thrust of the study. The preeminence of trade and macroeconomic policies over sectoral interventions, and in particular the strategic nature of the real exchange rate in allowing agriculture to compete domestically and internationally highlight the discussion.
