1产量与经济效益共赢的高效生态农业模式:以弘毅生态农场为例显示文摘化学物质的大量投入以及元素不能循环导致农田生态系统退化,耕地质量和产量均呈下降趋势,食物链受到污染.本研究从低产田开始,通过秸秆养牛、腐熟牛粪还田恢复地力;以物理+生物方法控制虫害;以人工+机械管理杂草,停用农药、化肥和除草剂,同时不用地膜、人工合成激素、转基因种子生产优质安全食品,并在线上与线下销售.10年的长期实验结果表明,所在村庄农田生态环境改善,减少农药用量58.3%;物理+生物控虫效果明显,每盏灯年捕获量从2009年的33 kg下降到2014年的2.1 kg,下降93.8%;年消耗秸秆1000 t,秸秆利用率从1.1%提高到62.5%.有机肥还田提高了土壤生物多样性,有机果园蚯蚓数量317条m^(-2),而普通果园只有16条m^(-2);大量有机肥还田(75 t hm^(-2)),土壤有机质从实验初期的0.7%提高到2.4%.粮食产量从最初的11.43 t hm^(-2)提高到目前的17.43 t hm^(-2),其中冬小麦(Triticum aestivum)、夏玉米(Zea mays)、大豆(Glycine max(Linn.)Merr.)和花生(Arachis hypogaea Linn.)产量分别超出山东省平均水平42.6%,60.9%,32.2%和38.1%.由于质量好,产品已销售往除西藏以外的30个省、市、自治区,经济效益明显,平均每公顷效益是普通农田的3~5倍,带动所在村庄67户农民从事高效生态农业.本研究可为国家制定生态农业发展规划、精准扶贫、农村环境保护等提供科学依据.蒋高明 郑延海 吴光磊 刘慧 池云花 冯素飞 李勇 李彩虹 李宗奉 苏本营 董群 乌云塔娜 LUCAS Mario LEFORT Zoe REGOLINI Margot 曾祥伟 贺新华 郭立月 战丽杰 唐海龙 韦继光 周平 曾彦 杨煜 宋守宽 刘秀 甄珍 刘海涛 孟杰 李静 李霄 李占 丁娜 博文静 虞晓凡 程达 梁啸天 李立君 徐磊 谷仙 宋彦洁 MUMINOV A.

2Science and prediction of monsoon heavy rainfall显示文摘With the increasing incidence of heavy rainfall events,particularly over the monsoon regions,the highly dense populations are more vulnerable[1].Research initiatives on observation,modeling,and prediction of monsoon heavy rainfall have been promoted actively by World Weather Research Programme's(WWRP)Working Group on Tropical Meteorology Research(WGTMR)of the World Meteorological Organization(WMO)since 2010.Series of monsoon-heavy-rainfall workshops were held in Beijing(2011),Petaling Jaya(2012),and New Delhi(2015)to benefit scientists worldwide and forecasters from the National Meteorological and Hydrological Services.An international Research and Development Project,namely,the Southern China Monsoon Rainfall Experiment(SCMREX)[2]was established in 2013 to coordinate field campaign experiments and to conduct scientific research on presummer(April-June)heavy rainfall processes in southern China.Yali Luo Liye Li Richard HJohnson Chih-Pei Chang Lianshou Chen Wai-Kin Wong Jing Chen Kalli Furtado John LMcBride Ajit Tyagi Nanette Lomarda Thierry Lefort Esperanza O.Cayanan 2019Science Bulletin2019,64,21:4
