防治核桃黑斑病药剂筛选及田间药效试验

核桃细菌性黑斑病是一种危害核桃的重要病害。为明确不同杀菌剂对核桃细菌性黑斑病菌的抑制作用以及田间防效。通过室内抑菌试验及田间喷雾防治试验,研究了中生菌素等14种杀菌剂对核桃细菌性黑斑病的抑制作用。结果表明,中生菌素等7种供试杀菌剂对核桃细菌性黑斑病原菌成团泛菌具有一定的抑制作用,其EC₅₀在40.27～252.41 mg·L^-1,其中中生菌素的抑制作用最强,EC₅₀为40.27 mg·L^-1,噻霉酮、硫酸链霉素和春雷霉素的抑制作用相当,EC₅₀分别为50.62、53.25、54.88 mg·L^-1,氟啶胺的EC₅₀为176.96 mg·L^-1。中生菌素、噻霉酮、氟啶胺和春雷霉素4种药剂田间药效试验结果表明,4种药剂对核桃黑斑病均有良好的防治效果,田间防效依次顺序为:中生菌素>噻霉酮>氟啶胺>春雷霉素。中生菌素对核桃果实黑斑病防效为81.35%,对核桃叶部黑斑病防效为82.65%。春雷霉素对核桃果实黑斑病防效为71.58%,对核桃叶部黑斑病防效为74.87%。中生菌素、噻霉酮、氟啶胺和春雷霉素等药剂可作为防治核桃细菌性黑斑病的理想药剂。     

Evaluation and Analysis of Bacteria Pollution in Dwelling Indoor Air

Tests and study were carried out on indoor air bacteria pollution in dwelling house inChongqing city. Based on the data of measured bacteria concentration of the indoor air,the reasons for indoor air pollution were analyzed. Ith was found that the bacteria seriously polluted the indoor air. The main factors influencing the indoor air bacteria pollution are moisture, natural ventilation and lighting conditions. The construction forms and decoration of the dwelling house are the secondary reasons for indoor air bacteria pollution. Measures and suggestions of preventing the indoor air bacteria pollution and improving the indoor air quality and environmental quality were presented.     

Study on the Energy Consumption of Atrium Buildings

This paper reviews the evolvement of the atrium. In this paper the function of atria in buildings and the thermal performance and climatic factors of atria were described. The factors influencing the energy consumption of atrium buildings were analyzed and some measures for energy saving were presented. By using a computer simulation, the impact of the atrium's physical parameters including atrium proportion, top-glazing area and atrium wall mass on its energy costs was studied.

广州市室内植物种类及应用状况调查

采用踏查和抽样调查法对广州市的商场、酒店、医院及写字楼等公共场所室内观赏植物的种类和应用情况进行了调 研。结果表明：在广州市大型商场、酒店、医院和办公大楼常用的室内植物共77 种（含变种和品种）,隶属62 属33 科,60%为观叶植物,25%为观花植物,13%为观形植物,2%为观果植物。广州的室内观赏植物以天南星科和龙舌兰科的观叶植物最为丰富,但多为外来植物,以草本植物最丰富,其次为灌木类和乔木类,蕨类植物和藤蔓类种类较少;应用频率较高的植物种类为绿萝（Epipremnum aureum）、富贵竹（Dracaena braunii)、也门铁（Dracaena arborea）、马拉巴栗（Pachira aquatica）、金钱树（Zamioculcas zamiifolia）、红掌（Anthurium andraeanum）、金心也门铁（D. arborea ’Victoria’)、心叶蔓绿绒（Philodendron scandens）、巴西铁（D.fragrans）、散尾葵（Chrysalidocarpus lutescens）。广州市室内植物以土培或基质栽培方式为主,水养花卉日渐流行,基于以上调查结果袁分析了广州市室内植物的应用现状,提出了要加强乡土室内观赏植物开发与研究的建议。
