现代农机在大型生态旅游区园林作业中的应用

随着人们环保意识的提高和城市绿化事业的发展,各地开始兴建大型生态旅游园区,由于生态旅游区的绿化面积较大,其种植、移植和养护过程中离不开机械自动化技术的支持。为此,本研究将现代化农机设备引入到了大型生态旅游区园林作业过程中,分析了当前园林机械的发展现状和存在的不足,并以修剪机械和自动化喷药装置为例,对生态旅游区引入农机设备的意义进行了论述。最后,重点对自动化喷药装置的作业效率和质量进行了验证,结果表明:采用自动化喷药装置比传统的喷药装置效率高,精准施药效果好,成本较低,适合引入到生态旅游区的园林作业中。

多功能园林作业机推土作业仿真分析

通过三维软件建立了多功能园林作业机推土作业的仿真模型,结合ADAMS 软件对推土作业过程进行了仿真分析,得出了推土作业时推土铲位移、速度、加速度的变化曲线及受力状况,为多功能园林作业机的结构优化设计提供了理论参考。

基于社会公众认同的绿化行业工装需求分析

作业工装是园林绿化行业一线作业人员的重要装备,文章立足于上海绿化行业现状及需求,通过问卷调查和实际调研的方式,对作业工装的需求、功能、材质等10多项指标进行统计分析,结果表明:绿化行业工装有而不一、杂而不齐,缺少相关的技术标准,从而造成工装存在功能性偏弱、舒适性偏差、标识性不强等问题。在此基础上,进一步分析总结了上海绿化行业工装目前存在问题,并提出建议性策略,以期为上海乃至全国绿化行业工装配置提供一定的参照依据。

Allelopathic effects of leaf litters of Eucalyptus camaldulensis on some forest and agricultural crops

Allelopathic effects of different doses of Eucalyptus camaldulensis leaf litters were investigated through an experiment in the green house of Institute of Forestry and Environmental Sciences, Chittagong, Bangladesh. Three popular agricultural crops： Falen （Vigna unguiculata）, Chickpea （Cicer arietinum）, Arhor （Cajanus cajan） and two widely used plantation trees： Sada koroi （Albizia procera） and Ipil ipil （Leucaena leucocephala） were selected as bioassay species. Experiment was set on tray at room temperature 27℃. The effects of different doses of leaf litter extracts were compared to the control. Results suggest that leaf litters of E, camaldulesis induced inhibitory effects, It was also found that the effect depend on concentration of extract and litterfall, type of receiver species. Higher concentration of the materials had the higher effect and vice versa. Though all the bioassay species were suppressed some of them showed better performance. Vigna unguiculata, Cicer arietinum are recommended in agroforestry based on this present Experiment output. In mixed plantation, Leucaena leucochephala is a better choice while compared to Albizia procera.

Benin Farmers Advance Through Chinese Agrotechnology

THE fluttering red,five-starred Chinese national flag guided us to the China-aided Agrotechnology Demonstration Center in Seme,20 or more km east of Cotonou,Benin＇s largest city.It stands within a gray-tiled,white-walled Chinese garden-style compound.＂Over the past several years,groups of Chinese agricultural experts and management staff have come to Benin to cooperate with locals in crop cultivation and breeding,animal husbandry and poultry, so speeding up Benin＇s agricultural development and contributing to the country＇s poverty reduction drive,＂ general manager of the center Huang Jianping said.
