水稻是中国最主要的粮食作物之一,其产量约占粮食作物总产量的40%;在全国约11×108hm2的粮食作物总面积中,稻田面积约占28%。20世纪80年代以来,水稻产区的水资源短缺已成为当地农业生产中的重要问题,各地试验、开发、应用与推广了许多种水稻节水灌溉模式。文章根据这些新的水稻灌溉模式试验结果与推广经验,将我国水稻节水灌溉主要模式归纳为浅、湿、晒结合,间歇淹水,半旱栽培和蓄雨型等4类。阐述了这些模式的田间水分控制标准以及节水、增产和提高水分生产率的潜力;提出了该4类模式的选择原则以及应用这些模式时应注意的问题;分析、讨论了推广这些模式能够持续节水与提高水分生产率的机理以及对环境的影响。

For improving wastewater quality, one of the dare of steelworks is reducing cyanide in wastewater of gas washing treatment of blast furnaces. Costs of existing treatments, stringent environmental regulations and changeable composition of water from gas treatment, have led to study how available treatments can be modified and to examine new ones. Ozonation is one of cyanide treatments, tested within a European project. A process model was set up with Aspen Plus®, to assess operating conditions and wastewater distinctive characteristics and to demonstrate treatment robustness. Process was modeled by theoretical reactors, taking into account all more affecting reactions. A genetic algorithm was exploited to find kinetic parameters of these reactions. After validation, the model was used to analyse scenarios, by considering also real contexts. Pilot tests were extended, process knowledge was enhanced and suggestions were obtained. To promote cyanide removal with ozone, temperature and pH values were 30°C and 10, respectively. With an ozone (mg/h)/water (L/h) ratio of 100 mg/L, batch mode ensure reaching cyanide regulation limit (0.2 mg/L) after maximum 4.5 h, if initial amount was less than 20 mg/L. Higher removal was obtained than in continuous mode due to constraints related to this last run. Higher wastewater contamination needed further time and more ozone.

稻田养鱼是一种传统的综合养鱼方式。近几年来,一批以特种经济品种为主导的稻渔综合种养新模式不断涌现,在经济、社会、生态等方面取得显著的成效。为了推广稻渔综合种养的经验,本文实地调研了湖北省两种典型的稻渔综合种养模式,其中“虾–稻共作”模式亩均纯收入超过3 000元,亩纯收入则是单纯种粮的3~4倍;“鳖–虾–鱼–稻共作”模式亩均纯收入近万元,是单一种植水稻亩均效益的12.8倍。本文还提出了加快产业发展的建议,包括进一步拓展种养殖空间、促进产业融合发展及加大政策扶持力度等。
