The study was conducted to develop electrical sow feeding (ESF) system for improving animal welfare of group housed sows.They were fed daily at a level of 2kg using automatic feeding system.The period of each feeding was set at about 20 minutes.The maximum possible number of sows fed by ESF system was around 45 heads.The ESF system ran well without any mechanical problems throughout the entire experiment.Feed intake of both individual and group housed sows showed similar range (below 2kg).ESF system was very effective in reducing feed loss.The amount of feed loss of ESF system was only 100g, while individually housed sows showed about 700g feed loss.About 85% of sows took feed once a day with ESF system.However the individually housed sows took it 2-3 times a day.

甘孜藏族自治州的乡城县是四川苹果产量较多的县之一,也是中国苹果的优质生态区,其主栽品种有金冠、红星、红冠、红富士、新红星等,近年新引进的早中熟新品种红津轻、红月、乔纳金等表现良好,现在大面积推广.当前,病虫危害是制约苹果产业发展的重要因素,严重影响乡城苹果产业的健康有序发展,为推广苹果病虫绿色防控与农药减量使用技术,实现病虫的可持续治理,乡城县农牧和科技局从保护生态环境和病虫害可持续治理的观念出发
搞好农药和药械的需求与预测工作对于确保防治农作物生物灾害、引导市场、调整农药品种结构、提高农产品质量、增加收入等具有重要意义.因此,根据河南省植保站豫保[2015]25号《关于做好2015年农药实际用药及2016年农药与药械需求预测工作的通知》的要求,信阳市植保站组织各县区植保专业技术人员,按照通知的要求,对本地区农作物种植情况、病虫草害发生与防治情况、农药械销售情况等进行了调查,并根据调查情况对
蔬菜是武山县推动县域经济发展和富民增收的首位支柱产业,全县蔬菜种植面积达2.43万hm2,总产量102万t,总产值近20亿元,蔬菜收入占到农民人均纯收入的46％.2014年,武山县被农业部和甘肃省农牧厅列为蔬菜病虫专业化统防统治与绿色防控融合试点示范县,按照"科学植保、公共植保、绿色植保"理念,积极探索蔬菜病虫害专业化统防统治与绿色防控融合试点工作,为实现绿色防控积累经验,取得了初步成效.
当前,随着我国现代农业的飞速发展,农药"双刃剑"的矛盾也日益突显,寻找"减药不减产"的抗灾减灾新出路迫在眉睫.专业化统防统治与绿色防控融合是坚持"预防为主、综合防治"的植保方针,树立"科学植保、公共植保、绿色植保"理念,以保障农业生产安全、农产品质量安全、生态环境安全、农业贸易安全"四大安全"为目标,以病虫防治专业化服务组织、新型农业经营主体为依托,以专业化统防统治为主要形式,以农作物病虫害全程绿
