<正>近年来,我国缓控释肥产业得到了快速发展,然而由于其成本高却严重制约了缓控释肥在全国大面积推广应用,无形中也影响了缓控释肥进一步快速发展。今年,作为我国缓控释肥龙头企业的金正大公司明确提出了"成为高端肥料供应商和受人尊重的农化服务商"的战略目标。金正大认为只有完善产业链,掌控原材料获取成本优势,精耕终端获取网络与服务优势,才能从根本上提高企业核心竞争力,彻底解决缓控释肥成本高的问题。为此,金正大实施了一系列重大的行动,不仅加大科研力度,降低生产成本,而且从上游资源到渠道下沉以及服务上下功夫,凸现产 相似文献

缓控释肥是一种通过各种调控机制使其养分最初释放延缓,延长植物对其有效养分吸收利用的有效期,使其养分按照设定的释放率和释放期缓慢或控制释放的新型肥料,具有增效、节肥、省工、安全、环保的明显优势。国家农业部目前正在重点推广这一新品种。然而,在缓控释肥的发展过程中,业界还存着诸如怎样降低成本、提高技术含量、出台并规范行业标准及配套措施、帮助农民认知并接受这种新型肥料等现实问题,不解决这些问题,势必会影响缓控释肥的推广和应用。 相似文献

沸石与化肥制成复混肥 减少无效施肥的高昂成本 总被引:1,自引:0,他引:1
中国农业在过去20年来实现了农业奇迹,即只用了全球7%的耕地,生产了全球20%的粮食,但与此同时,也消耗了全球35%的化学肥料。化肥的对土壤生态的破坏早已不言而喻,加上天候环境的恶变,许多良田沃土在本世纪面临了严峻的退化形势,而缓/控释肥也因精准的抓住了现代农业的需求而迎来起飞点。根据国际肥料工业2010年专题报导,使用包衣性的缓/控释肥,每年每公顷于土壤中所残留的化学树脂材料为50~500公斤。然而,二害相权取其轻,对比 相似文献

Workload control under continuous order release 总被引:1,自引:0,他引:1
Workload control is a production planning and control concept specifically designed for complex manufacturing environments. Past research on Workload control has been essentially focused on discrete order release. This means that release of orders to the shop floor takes places on a periodic basis. Continuous order release has been somehow neglected, in spite of its apparent potential for improving system performance, including the reduction of order flow times. This paper presents a simulation study of this order release approach. The study contributes for improving the basis for setting workload norms, selecting the workload control strategy and deciding upon routing alternatives under continuous order release. 相似文献

We examine the out-of-market gap – the time between the end of a film’s theatrical run and its release on DVD – for a sample
of U.S. films during 1988-2005. The average gap declined from 58.14 days in 1998 to 27.93 days in 2005; by 2005, 39% of the
films were released on DVD prior to leaving the theaters. Probit and hazard models are estimated to explore the factors that
influence a distributor’s decision to release a film on DVD before it exits the theaters, and the timing of the release for
films that appear on DVD after they leave the theaters.

A simple, spreadsheet-based rapid modeling approach to analysis of input control is developed. This approach uses relationships which allow decomposition of a job shop queuing network. Order release is based on a minimum release time interval, dictated by the bottleneck machine utilization. The objectives are to develop insights into how input control affects work flow and how rapid models can help in achieving this. The rapid model performs well and the order release mechanism is shown to be robust. Economic analysis based on throughput, inventory and lead time tradeoffs is provided. The value of input control is shown to be dependent on the cost structure. The impact on profitability is small, however, relative to the impact of operating at the optimal utilization level. 相似文献

2011年6月23日国际能源机构(IEA)宣布计划释放总量达6000万桶的石油储备,以缓解利比亚原油出口中断对国际石油市场的冲击。本文认为,此次石油储备释放计划的出台,是金融危机以来主要发达国家面临经济复苏乏力和公共政策工具匮乏的产物,具有试探性,以观察其对国际油价和相关各国的影响。鉴于本次储备释放量的有限性、欧佩克可能作出的负面反应以及抵消性的挥发-抑制效应,本次储备释放对油价的影响将是比较小的。但考虑到世界宏观经济状况的不确定性,对其后续影响仍需谨慎判断。中国正在逐步形成庞大的石油储备规模,对IEA特别是美国石油储备释放的历史考察,有助于促使中国认真思考、谨慎建构科学的战略石油储备运用制度。 相似文献

《Telecommunications Policy》2017,41(4):242-252
It has been argued that infrastructure unevenness rigidifies into more lasting structures of socio-economic and political privilege and advantage. This paper focuses on telecommunication infrastructure as the backbone of the fast-growing digital economy, and raises important questions about the early National Broadband Network (NBN) rollout in Australia. The paper asks whether there was any case of pork barrelling in the selection of early release sites that enjoyed a regional competitive advantage against other localities that had to wait several years to receive the infrastructure. The answer to this question then leads to a second question about the degree to which voting in the early NBN release sites has swung following the infrastructure rollout. In order to answer these questions the paper examines the voting patterns in the earlier NBN release sites versus all electorates in the Federal elections in 2007–2013 using the data available via Australian Electoral Commission. Findings show trends of politically targeted funding, followed by vote swing in the very next election. 相似文献
