71 团玉米密植高产全程机械化生产技术模式发展调研
本文从种植品种、种植密度与种植方式、机械化作业和收储烘干等环节对新疆生产建设兵团第四师71团场玉米生产技术的发展进行了调研。分析表明,71团场位于西北灌溉玉米区,通过规模化、标准化生产和统一作业管理,以密植增产为基础、籽粒收获为核心、绿色防控与秸秆还田为保障构建的玉米密植高产全程机械化绿色生产技术,实现了高产和高效的协同提高与绿色可持续生产。经农业农村部专家指导组田间测产验收,2012年、2014年和2017年连续创造16701 kg/hm2(1113.4kg/亩)、18414 kg/hm2(1227.6 kg/亩)和18447 kg/hm2(1229.8kg/亩)的全国玉米大面积(10500万亩)高产纪录,净利润在15000元/hm2(1000元/亩)以上,为现代玉米生产树立了成功的模式和样板。
英文摘要:
In this study, based on such technical procedures as planting variety, planting density, total mechanization operation, storage and drying, a survey was carried out on the progress of maize production in 71st farm, 4th Agriculture Division, XPCC, China. According to the analyzed result, it is shown that, the maize production technology based on dense planting for high yield, lied in mechanical grain harvesting, and emphasized on green prevention and straw returning, has constantly achieved the nationwide high yield records of maize at large area (700hm2) in 71st farm in the irrigation production area of maize, Northwestern China, respectively,which were identified by the experts from the ministry of agriculture and rural affairs of PRC in 2012(16701 kg/hm2), in 2014(18414 kg/hm2), and in 2017(18447 kg/hm2). With a net profit over 15000Yuan/ hm2, it has realized the coordinative improvement between high yield and high efficiency, as well as green sustainability of maize production, thereby, thus setting a representative mode of modern maize production.
