利用GPRS无线传输，实现我省环境监测传输系统

我省环境监测的远程数据传输也应用多年，但目前普遍存在着设备老化、传输手段落后、设备运行不稳定等状况，急需对现有系统进行换代或改造。通过对目前常用的数据传输方式的比较分析，采用GPRS传输方案实现我省环境监测数据远程传输系统是最优的，是斜学的、可行的。     

纳米技术在环境保护中的应用

介绍了纳米技术在环境保护领域中的应用现状、存在问题和今后的研究方向。纳米光催化剂、纳米过滤技术和纳米级的水处理剂在水处理中有着广泛的应用;纳米级的汽车尾气净化催化剂和其它纳米催化剂在大气污染控制方面有着普通材料无法比拟的优势;纳米技术在噪声污染控制和环境监测等方面也有广泛的应用。但是,纳米技术同时也存在光催化时光利用率低、催化效率低、纳米功能材料工作条件要求高等问题。     

Integrated nutrient management and waste recycling for restoring soil fertility and productivity in Japanese mint and mustard sequence in Uttar Pradesh, India

Supplementing the nutrient requirement of crops through organic manures plays a key role in sustaining soil fertility, and crop productivity and reducing use of fossil fuels. Field experiments were conducted for 2 years at two different locations (i.e. Lucknow and Pantnagar) in Uttar Pradesh, India. The objectives of the study were to assess the herb and essential oil yields of Japanese mint (Mentha arvensis cv. Hy 77), and its nutrient accumulation under single and combined applications of organic manures and inorganic fertilizers (NPK). Changes in physical and chemical characteristics of the soils (Fluvisols, Mollisols) were also determined. Eight treatments comprising different combinations of NPK through inorganic fertilizers and farm yard manure (FYM) were compared. The distilled waste of mint after extraction of essential oil was recycled to soils in the plots to supplement the nutritional requirement of the succeeding mustard crop (Brassica juncea cv. Pusa Bold). Herb and essential oil yield of mint were significantly higher with combined application of organic and inorganic sources of nutrients as compared to single applications. Accumulation of N and P was at par under full inorganic and combined supply whereas, K accumulation was higher with the former. Soil organic C and pH after harvest of mint did not significantly differ among the treatments, but the level of mineralizable N, Olsen-P and NH₄OAc extractable K were higher in soil with integrated supply of nutrients. Significant increase in soil water stable aggregates, organic C, available NPK and microbial biomass, and decrease in soil bulk density were observed with waste recycling over fertilizer application. These benefits were reflected in the seed and stubble yield of mustard which succeeded mint. This study indicates that combined application of inorganic fertilizers with organics helps in increasing the availability of nutrients and crop yield and provides a significant effect to the succeeding crop. Similarly, recycling crop residues reduces the need for fossil fuel based fertilizer, and helps in sustaining and restoring soil fertility in terms of available nutrients and major physical and chemical characteristics of the soil.
