小麦种子的类别

种子的类别分为育种家种子 ,原种和良种。育种家种子是指育种家育成的遗传性状稳定的品种或亲本最初一批种子。原种是指用育种家种子繁殖的第一代至第三代或按原种生产技术规程生产的达到原种质量标准的种子。良种是指用常规种原种繁殖的第一代至第三代和杂交种达到良种质量标准的种子。以上规定是对所有农作物种子而言的。具体到小麦 ,育种家种子指由育种家直接掌握 ,用来繁殖原种的遗传性状稳定 ,纯度达１００ %的那部分种子。其性状代表该品种的标准性状 ,有时也称为原原种。在育种家种子不能满足生产需要时 ,由育种者在该品种选取足够数…     

对加速实施广西农作物种子产业化工程的思考

加快种子产业化进程

种子是农业增产中最重要的因素,选育和使用良种是促进农业增产的一项投资少、见效快的主要措施。建国以来,我国种子工程取得了很大成绩,一大批良种的育成和推广应用,为促进农业发展做出了重要贡献。但目前种子工作还存在不少问题,主要是用种"多、乱、杂",经营"小、散、低",管理体制"政、事、企"不分,科研与生产"育、繁、推"脱节。如何解决这些问题,记者日前采访了农业部有关方面的负责人。这位负责人介绍说,为了切实改变这种状况,今年国家将积极推进种子产业化,目标是达到"五化",即:生产标准化、经营企业化、管理法制化、育繁推销一体化、种子商品化,力争5年内使粮棉油等主要作物品种更新1～2次,良种覆盖率达到95%以上,小麦、水稻等常规作物统一供种率由20%提高到

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.
