基于Prosumer的互联网农业分享经济模型

构建分散小农户合作化联合,碎片化消费者社群化聚合,消费者充分参与生产端消费体验并与生产者融合为Prosumer的互联网农业共享经济模型.研究表明,消费者社群化聚合,生产者合作化联合,消费者与生产者融合为生产消费者是互联网农业分享经济有效实现形式,可促进供应链信息对称,产销对接和交易成本降低,提升农产品质量安全水平和消费者对国内农产品质量安全的信心."土地托管","乡村货的"和"俺家特供"是当前我国农业分享经济在生产,流通和消费端出现的典型案例,它们的融合发展必将成为我国互联网农业分享经济发展的主要方向.

近红外光谱技术在土壤养分分析中的研究进展及应用前景

精准农业是近年来国际上农业科学研究的热点领域,是现代信息技术和传统农业紧密结合的产物。近红外光谱技术(NIRS)作为一种无损、实时、准确的分析手段,在土壤学领域的应用逐渐得到了人们的重视,是实现精准农业的有效手段之一。对其目前在土壤学领域的应用进行了介绍和分析,认为NIRS在土壤学领域的发展方向应该是田间信息实时采集技术,即在田间条件下利用便携式NIRS分析仪对土壤养分和农作物苗情进行实时分析和处理,另外NIRS还可以与空间遥感技术相结合,宏观掌握农作物所需营养及其长势信息,从根本上改变我国粗放型农业现状。     

An Operations Research Approach to the Problem of the Sugarcane Selection

Selection for superior clones is the most important aspect of sugar cane improvement programs, and is a long and expensive process. While studies have investigated different components of selection independently, there has not been a whole system approach to improve the process. This study observes the problem as an integrated system, where if one parameter changes the state of the whole system changes. A computer based stochastic simulation model that accurately represents the selection was developed. This paper describes the simulation model, showing its accuracy as well as how a combination of dynamic programming and branch and bound can be applied to the model to optimise the selection system, giving a new application of these techniques. The model can be directly applied to any region targeted by sugarcane breeding programs or to other clonally propagated crops.

Applications of Infrared Spectroscopy to Biochemical,Food, and Agricultural Processes

Abstract

Integrated investigations on infrared spectroscopic characteristics of metabolites and on applications of infrared spectroscopy to foodstuff production, food processing, and tasting are described. As the important metabolites, saccharides, which play very important roles in various functions, located in the central position of the metabolic pathways, were selected, and the spectral features of the saccharides and related materials are discussed. Additionally, the applications of spectral analysis to the monitoring of the enzyme reaction and the sugar metabolic processes, which are the main materials in food processing, are described. Furthermore, the studies on the spectroscopic measurements during the cultivation of agricultural products as foodstuffs and in the tasting as the final quality evaluation of foods are represented. These results suggest that infrared spectroscopy could be very effective for evaluating foodstuff production and the tasting of the processed foods and that the applied topics should provide fundamental information about the spectral behavior of the metabolites and bioproducts.
