【摘要】 针对内蒙古中西部地区水资源严重匮乏、年降雨量少、在马铃薯生产中水资源利用率低的现状,开展了抗旱节水丰产高效技术研究。试验以耕翻35 cm、垄沟每隔5 m设一挡水堰、培土3次、培土厚度18 cm、喷施大西北微肥3次9kg/hm~2为旱作丰产高效技术集成处理条件,以耕翻20 cm、无挡水堰、培土2次、培土厚度12 cm、不喷施任何调节剂为对照条件。结果表明:集成试验产量32 278.05 kg/hm~2,比对照增产41.59%;集成试验纯收益13 281.90元/hm~2,集成试验比对照增效6 627.15元/hm~2,增效率为99.58%。在旱地马铃薯栽培上应用旱作高效集成技术,可以显著提高马铃薯产量,增加经济效益。更多还原

【Abstract】 To address the current situation of severe shortage of water resources,low annual rainfall and low utilization rate of water resources in potato production in the central and western regions of Inner Mongolia autonomous region,research on drought-resistance,water-saving and high-yield efficient technology were conducted.The conditions of integrated treatment were as follows.Ploughing depth was 35 cm;the gully was set to a water retaining raft per 5 m;the soil was ploughed 3 times;the thickness of the soil was 18 cm;and the micro-fertilizer was sprayed 3 times at 9 kg/hm2.The potato yield reached32 278.05 kg/hm2,which was increased by 41.59% compared with the control.The economic benefit was 13 281.90 yuan/hm2,which was increased by 99.58% compared with the control.The conditions of the control were as follows.Ploughing depth was20 cm;the gully was not set;the soil was ploughed 2 times;and the micro-fertilizer was not sprayed.The application of highefficiency integrated technology of dryland potato cultivation can significantly increase potato yield and economic benefit.更多还原
