以西南地区麦/玉/薯三熟制种植模式为研究对象,研究了不同保护性耕作模式下旱地土壤水分动态变化、水分利用效率、作物产量和经济效应。结果表明,不同保护性耕作对整个农田生态系统产量和水分利用效率具有显著影响。秸秆覆盖(TS)、地膜覆盖(TM)、秸秆覆盖+地膜覆盖(TSM)和垄作+秸秆覆盖+地膜覆盖(RSM)能改善7,10月份0—60cm土层土壤含水量及贮水量,而垄作(R)、垄作+秸秆覆盖(RS)和垄作+地膜覆盖(RM)的作用不明显。与平作(CK)相比,RSM,RM,RS,TSM,TM,TS和R分别使系统增产10.52%,6.11%,6.77%,4.59%,5.12%,3.15%,1.24%。这些处理对水分利用效率和降水利用效率的增幅分别为1.26%～11.08%,1.27%～10.57%。研究结果说明,从WUE、降水利用效率、产量效应、经济效益这4个方面来看,垄作+秸秆覆盖+地膜覆盖耕作模式综合效益最佳。

A field experiment was conducted in order to evaluate the economics of different genotypes of cotton planted under various planting densities at Agronomic Research Area, University of Agriculture Faisalabad during the summer season in 2013. Sowing was done manually with the help of dibbling method on both sides of the bed in standing water, with bed distance of 75 cm. The crop was sown in May and the experiment comprised of following FH-142, FH-114 at various densities (S1 = 10 cm, S2 = 15 cm, S3 =20 cm, S4 = 25 cm, S5 = 30 cm). Data regarding net field benefit, benefit cost ratio, dominance analysis, and marginal rate of return were collected. The experimental results showed that maximum NFB of (Rs. 222,575), (Rs. 202,483) was achieved in FH-142 and FH-114 when planted at a plant spacing of 20 cm and 15 cm respectively. While the maximum benefit cost ratio (BCR) of 1.76 was found in genotype FH-142 at plant spacing of 20 and 25 cm and FH-114 depicted maximum BCR of 1.62 and 1.61 when planted at plant spacing of 15 and 20 cm, respectively. Dominance analysis of FH-142 planted at 10 and 15 cm while FH-114 at plant spacing of 10, 15 and 20 cm was dominated due to their lower net field benefits as compared to other treatments, while maximum marginal rate of return (1494%, 788%) by planting FH-142, FH-114 was obtained at 30 cm and 25 cm recorded respectively.

An experiment was conducted at Rice Research Institute, Kala Shah Kaku in 2010 during kharif season to study the influence of nitrogen (N) and potash (K) on severity of Bacterial leaf blight (BLB) of rice (Oryza sativa L.) aimed at improving productivity. The experiment was laid out in randomized complete block design with factorial arrangement with three replications. Treatments comprised of: 0 kg N ha-1, 75 kg N ha-1, 100 kg N ha-1, 125 kg N ha-1 and 0 kg K ha-1, 50 kg K ha-1, 75 kg K ha-1, 100 kg K ha-1. Data on disease severity and paddy yield were recorded using standard procedures. Paddy yield was affected significantly by various combinations of N & K. In case of bacterial leaf blight, minimum diseased incidence percentage was observed when nitrogen alone was applied @ 75 kg·ha-1 in contrast to fertilizer applied @ 125 kg N ha-1 + 50 kg K ha-1 which showed maximum diseased incidence percentage. Maximum paddy yield (4.32 t·ha-1 ) was recorded when rice was fertilized @ 75 kg N ha-1 + 100 kg K ha-1 as compared to sole fertilization of 75 kg K ha-1 that produced minimum paddy yield (2.40 t·ha-1). Maximum gross income, net returns and benefit cost ratio were obtained where rice crop was fertilized @ 75 kg N ha-1 and 100 kg K ha-1.

One of the main reasons behind reduced cane yield is pathetic method of planting. Planting method and row spacing are the most important yield contributing factors in sugarcane. A field experiment was carried out in order to determine quality and yield of sugarcane in various spatial arrangements. Treatments are 180 cm spaced trenches with triple row strips;180 cm spaced trenches with alternate row strips;120 cm spaced trenches with double row strips and 60 cm spaced furrow with single row. Perusal of data revealed that 3.6%, 13.4%, 15%, 15.3% more cane diameter (cm), cane length (cm), stripped cane yield (t·haˉ1), sugar yield (t·haˉ1) were obtained from 180 cm spaced trenches with triple row strips as compared to conventional planting method i.e. 60 cm spaced furrows. While the number of millable canes mˉ2, polarity %, cane juice purity %, cane juice %, commercial cane sugar % and cane sugar recovery % remained non-significant by different planting techniques.

电致化学发光是一种电化学反应导致的化学发光现象。常见的电化学发光体系有钌配合物、鲁米诺、半导体量子点、纳米簇、光泽精和过氧化草酸酯等。其中钌配合物和鲁米诺电化学发光由于适用范围广、灵敏度高、重现性好、成本低等优点,而成为研究最多的体系之一,特别是钌配合物电化学发光在临床分析中的广泛应用更使之成为重点的研究体系。电化学发光中常常用到纳米材料,如将含有发光试剂的纳米材料作为标记物用于免疫分析、核酸分析和基于适配子的分析、将纳米材料用作电化学发光的催化剂或将纳米材料作为电化学发光试剂等[1-3]。而电化学发光分析性能等与其所使用的纳米材料的组成和结构等密切相关。在这里我们介绍近一两年内开展的纳米材料制备及其在吡啶钌和鲁米诺电化学发光分析应用的部分工作,如纳米多面体电化学发光催化研究、基于功能化二氧化硅球的臭氧的检测方法、基于能量转移的TNT分析方法和基于重氮盐功能化纳米材料的电化学发光分析等[4-7]。

Aim: To estimate the rates of cataract blindness and cataract surgical coverage and to assess the visual outcome of cataract surgery among individuals aged ≥50 years in Orakzai Agency, Pakistan. Methods: 1600 individuals aged ≥50 years were selected using probability proportional to size sampling. The main outcome measure was bilateral cataract blindness which was defined as visual acuity of <3/60 in the better eye with best available correction and with obvious central lens opacities/ absence of red reflex in both eyes. Results: A total of 1549 people were examined; the coverage rate was 96.8%. Of individuals who were examined, 958 (61.8%) were men. The overall prevalence of bilateral cataract blindness was 4.8%(95%CI: 3.8%to 5.9%). Women had a 2.1-fold greater prevalence of bilateral cataract blindness than men (7.1 %(5.0%to 9.2%) v 3.4%(2.3%to 4.6%); p=< 0.0001). However, cataract surgical coverage rates were lower for women than men. The overall quality of previous cataract surgery was poor: 43.1%eyes with cataract surgery had VA <6/60. 73.3%people with bilateral cataract blindness reported they could not undergo cataract surgery because they were too poor to afford its cost. Conclusion: The unacceptably high rates of cataract blindness and poor affordability and visual outcome of cataract surgery calls for the establishment, in the agency, of static cataract surgical services that are high quality, affordable, and gender sensitive.
