论我国非粮生物质原料的非粮属性   总被引:1,自引:1,他引:0  
能源安全与粮食安全既相互依赖又相互影响,发展生物质能源具有非常重要的战略地位,而非粮原料供应是生物质能源产业发展的最大瓶颈。非粮原则的本质是不能影响粮食安全,因而狭义的非粮生物质应定义为谷物籽粒以外的生物质。以谷物为粮食生产统计的国际口径,我国已基本实现了粮食自给,而且,据预测2029年当我国人口达到最多时,仍能保持基本的粮食安全。因此,谷物类籽粒毫无疑问不属于非粮生物质原料的种类,谷物籽粒类以外的农林业产品属于非粮生物质原料。豆类作物籽粒、薯类作物薯块、油料作物类籽粒和糖料作物含糖器官,属于受限制发展的非粮生物质原料种类;非食用的动植物产品及其他有机废弃物属于鼓励发展的非粮生物质原料种类。  相似文献

国外兽用抗生素减量化实践经验及其对我国的启示   总被引:1,自引:0,他引:1  
兽用抗生素减量化行动对畜禽养殖业绿色健康发展具有重要意义,由于我国兽用抗生素减量化行动起步较晚,目前尚无具体的行动指南,同时畜禽养殖环境差异较大导致全面推行也较困难。因此,在借鉴国际相关组织和畜牧业发达国家兽用抗生素减量化实践经验的基础上,结合我国畜禽养殖业发展现状,提出以下建议:普及安全用药知识,健全法律法规体系,添加畜产品“减抗、无抗”标签,开展动物性食品兽用抗生素残留风险评估工作,建立养殖场与兽医关系网,指导养殖场做好生物安全防控,完善兽用抗生素使用监控管理网络,以期为我国全面开展兽用抗生素减量化行动提供参考依据。  相似文献

The application of mineral and organic phosphorus fertilizers to arable land has greatly increased crop yield to meet the world food demand. On the other hand, impurities in these fertilizers, such as heavy metals, are being added to agricultural soils, resulting both from the raw materials themselves and the processes used to obtain the final product. Cadmium, a non-essential and toxic heavy metal, has been found in relatively high amounts in common P fertilizers obtained from sediments. This metal poses a high risk for soil fertility, crop cultivation, and plants in general. Furthermore, human health might be compromised by the cadmium concentrations in agricultural and livestock products, due to the bioaccumulation effect in the food web. The accumulation in the different matrixes is the result of the high mobility and flexible availability of this harmful metal. This review summarizes risks to human health, the factors influencing cadmium movement in soils and crop uptake, as well as common plant responses to its toxicity. In addition, it summarizes cadmium balances in soils, trends, long-term experiments, and further studies. Cadmium inputs and outputs in arable soil, together with their calculated concentrations, are compared between two different regions: the European countries (in particular Germany) and China. The comparison appears useful because of the different proportions in the inputs and outputs of cadmium, and the diverse geographical, environmental and social factors. Moreover, these variables and their influences on cadmium contamination improve the understanding of the pollution from phosphate fertilizers and will help to establish future mitigation policies.  相似文献

Within a given culture – whether industrialized or more tradition oriented – essentially the same fundamental medical theories, practices, and pharmacopoeia tend to be applied to human and non-human sickness and patients. In modern industrialized societies, however, healthcare services are sharply divided between human and veterinary medicine. There is likewise a sharp division between practitioners in these two health sectors: medical doctors and veterinarians. Yet in non-Western, traditional or indigenous medical systems, the same practitioners often treat both humans and animals. There is a growing body of literature that attests to the efficacy of traditional health practices and herbal medicines for the prevention and treatment of both human and livestock ailments.The authors argue for an intersectoral approach to human and veterinary health services in poor countries, especially those targeted to rural people with LIMITED access to modern health services. Extension of conventional medical and veterinary services is particularly difficult and costly in Third World countries where the necessary infrastructure (roads, clinics, labs, cold chains, etc.) is poorly developed and where much of the populace and their livestock reside in remote, rural areas, or where people may be nomadic or transhumant. Consideration should therefore be given to the joint delivery of human and livestock healthcare and related services, as well as to linking informal, ethnoveterinary practices and practitioners with more formalized systems of veterinary AND medical practice. Several advantages of such an approach are identified and explored.  相似文献

Research Progress and Prospect of Life Cycle Assessment in Animal Husbandry   总被引:1,自引:1,他引:0  
Life Cycle Assessment (LCA) is a generally accepted method to evaluate the overall environmental burden and production efficiency during the entire life cycle of a product, which is widely used for production management structure optimization in the enterprises and policy formulation in governments. In recent years, for food safety and environmental protection considerations, more and more studies emphasize that the LCA method should be used in animal husbandry to comprehensively assess the environmental burden and resources consumption during the animal-source food production. In China, LCA research and application of animal husbandry are rare, especially in the northern grassland pastoral area, which are the main livestock produce region, and no LCA research on the local livestock production system has been carried out. This paper reviewed the framework and research status of livestock production LCA methods on the main sections and processes, including (1) the goal and scope definition of livestock husbandry LCA; (2) life cycle inventory (LCI); and (3) life cycle impact assessment (LCIA). Through review the domestic and foreign LCA literatures on animal husbandry production, we noticed that the frame and methodology of animal husbandry LCA had been constructed well in developed country. It had an importance instructing significance for the research and practical application of Chinese animal husbandry LCA. However, we also needed to recognize that due to the differences in the specific situations of the livestock industry between domestic and foreign country, foreign LCA experience should not be applied directly in China. First of all, in the northern pastoral areas of China, family farm is the main production system mode of local livestock production, unclear boundaries between herdsmen's life needs and livestock production inputs exist in this system, therefore, it is difficult to apply the foreign experiences directly. Secondly, it is really a challenge to collect the data required for livestock husbandry LCA, which is the biggest restrictive factor of LCA application in livestock production in China. Third, compared with the animal husbandry developed countries, such as European countries, the United States and Australia, due to the gaps in livestock production technology and management methods, the livestock production in the northern pastoral areas of China is affected more by natural factors, such as precipitation, and various marketing factors, including the market supplies and demands. This is also an important issue that must be considered in the research and application of animal husbandry LCA in China. In order to widely practice Chinese livestock husbandry LCA, the following aspects should be improved: (1) the investigation about material input and output of livestock husbandry production in the northern pastoral areas of China should be carried out to collect necessary data; (2) the Chinese animal husbandry LCA database should be established in order to improve the accuracy of livestock husbandry LCA; and (3) we should strengthen the interdisciplinary study to clarify the natural and social driving factors in the development of animal husbandry, and to provide data reference and technology support for the sustainable development of animal husbandry in the northern pastoral areas of China.  相似文献

生命周期评价(life cycle assessment,LCA)作为一种全程评价产品总体环境影响和生产效率的方法,被广泛应用于企业优化生产经营结构和政府政策制定等方面。近年来,出于粮食安全保障和生态环境保护的考虑,LCA在农牧生产中的应用越来越受到重视。但我国相关方面的研究和应用并不多见,特别是作为畜牧业重要产区的北方草原牧区,尚没有开展针对当地畜牧生产体系的LCA研究。在这一背景下,本文围绕主要环节和流程对国内外畜牧生产LCA方法框架和研究现状进行了综述,主要从LCA研究目的与范围的确定、生命周期清单分析和影响评价三个方面展开。国内外文献综述表明,国外畜牧产业中LCA的应用已相当普遍,无论从方法上还是技术上都已经相当成熟和完备,对我国畜牧产业LCA科学研究和实际应用均有较强的借鉴意义。然而,由于国内外畜牧产业的具体情况差异,国外LCA经验难以直接应用到国内。首先,在我国北方牧区,家庭牧场是当地畜牧生产的主要经营方式,具有季节性放牧与圈养舍饲结合、不同牲畜混养、牧民生活和生产经营界限不明确等特点,难以直接套用国外方法。此外,在我国开展畜牧生产LCA研究所需的数据收集非常困难,这是制约我国畜牧生产LCA应用的最大短板。最后,由于畜牧生产技术及经营方式的差距,相比于欧美澳等畜牧业发展成熟国家,我国北方牧区畜牧生产受降水等自然因素及市场供求价格因素影响年际间差异更大,这也是我国开展畜牧生产LCA研究必须考虑的问题。为了使 LCA 能够精准且广泛地应用于我国畜牧产业,应从以下几个方面进行改进:首先,开展我国北方牧区不同规模畜牧生产经营系统物料投入和产出的调查和研究,为畜牧产业LCA研究收集必要数据;其次,根据我国畜牧产业的特征建立并完善适合国情的畜牧业LCA标准方法和数据库,提升我国LCA结论的准确性;第三,在我国畜牧LCA研究中还应加大学科交叉力度,理清畜牧产业发展中的自然和社会驱动因素,为我国北方牧区畜牧产业的可持续发展提供数据参考和科技支撑。  相似文献

Sensing technologies for precision specialty crop production   总被引:6,自引:0,他引:6  
With the advances in electronic and information technologies, various sensing systems have been developed for specialty crop production around the world. Accurate information concerning the spatial variability within fields is very important for precision farming of specialty crops. However, this variability is affected by a variety of factors, including crop yield, soil properties and nutrients, crop nutrients, crop canopy volume and biomass, water content, and pest conditions (disease, weeds, and insects). These factors can be measured using diverse types of sensors and instruments such as field-based electronic sensors, spectroradiometers, machine vision, airborne multispectral and hyperspectral remote sensing, satellite imagery, thermal imaging, RFID, and machine olfaction system, among others. Sensing techniques for crop biomass detection, weed detection, soil properties and nutrients are most advanced and can provide the data required for site specific management. On the other hand, sensing techniques for diseases detection and characterization, as well as crop water status, are based on more complex interaction between plant and sensor, making them more difficult to implement in the field scale and more complex to interpret. This paper presents a review of these sensing technologies and discusses how they are used for precision agriculture and crop management, especially for specialty crops. Some of the challenges and considerations on the use of these sensors and technologies for specialty crop production are also discussed.  相似文献
