Factors and scenarios affecting a farmer’s grain harvest logistics

This paper explores how changes in Australia’s grain industry supply chains are likely to impact on the nature and profitability of an Australian farmer’s grain harvest logistics. A simulation model is used to show how receival site rationalisation, cheaper on‐farm storage, larger trucks, higher‐yielding crops and new harvest technologies, separately and in combination, affect the nature and profitability of a farmer’s grain harvest logistics. Applying the model to a typical Australian grain farm shows that many of these changes unambiguously advantage the farm business, and often, the combination of these changes increases a farmer’s harvest profits by at least 10 per cent. For many farmers, the task of efficiently designing and managing harvest logistics will be an increasingly difficult yet important series of choices due to the range of storage options, grain pathways, crop portfolios and market opportunities that are arising. A farmer’s decisions about cost‐effective on‐farm storage and transport, and their judicious use, will be a key contributor to additional profit in future years.     

Domestic grain market reform in china: the contribution of economic policy research funded by ACIAR

This paper reports an assessment of the impact of economics research into domestic grain marketing policy in China, which was partly supported by the Australian Centre for International Agricultural Research. A financial analysis was conducted to value the contribution of these projects in bringing forward the adoption of more liberalized grain marketing policy. An estimate had to be made of the potential welfare gains from market reform in China because grain marketing policy in China in recent decades has been characterized by periods of reform alternating with periods of retrenchment in the face of uncertainty about how best to ensure food security. Any attempt to attribute some share of these potential gains to a particular research project is highly subjective when there are multiple sources of policy advice. The potential benefit cost ratio from the Australian investment may be in the order of 5 to 10:1.     

我国玉米生产地位、优势与自给率分析

[目的]系统分析我国玉米生产地位、优势和世界人口大国玉米自给率水平,提出未来我国玉米自给率目标及实现路径,为国家粮食安全决策提供参考。[方法]以1980—2017年我国玉米及小麦和水稻等主要粮食作物生产与进出口系列数据、2010—2017年世界人口大国玉米生产与进出口系列数据、我国玉米主产区及美国主要粮食作物生产成本数据、我国玉米主产区主要粮食作物灌溉用水数据、我国主要粮食作物示范田最高单位面积产量、未来我国玉米等主要粮食消费需求等数据为样本,应用时间序列比较分析方法,分析我国玉米生产地位、优势和降低玉米生产成本的关键所在。[结果]玉米是我国规模最大、发展最快、自给率水平最高、生产优势最为明显、增产潜力和消费需求增长空间最大的粮食作物;世界上绝大多数人口大国保持玉米自给。[结论]我国玉米生产具有相对优势,具有很大的降本增产潜力,是决定未来我国粮食安全的重要要素,应将玉米与水稻和小麦予同样重要地位,继续保持目前95%以上的自给率水平。

碎麦提取物与昆虫信息素提取物混合诱捕多种储粮害虫效果研究

本文通过实验室模拟仓实验,研究了碎麦提取物与锈赤扁谷盗Cryptolestes ferrugineus、、锯谷盗Oryzaephilus surinamensis、赤拟谷盗Tribolium castaneum、玉米象Sitophilus zeamais、米象Sitophilus ory zae、谷蠹Rhyzopertha dominica信息素提取物混合诱捕储粮害虫效果的影响:本实验应用6种储粮害虫信息素提取物与碎麦提取物混合分别对多种储粮害虫进行诱捕,发现当多种害虫共存时,碎麦提取物与害虫信息素提取物混合对同种害虫的诱捕超过了单独使用碎麦提取物或同种害虫的信息素提取物的诱捕效果,而对于其它害虫的诱捕也都有较显著的增强作用。如碎麦提取物与米象信息素提取物混合除了对米象诱捕有增强作用外,对玉米象也有较好的诱捕作用;结果再次证明昆虫信息素结合食物引诱剂对监测害虫,特别是储粮害虫有较好的增效作用。
