摘要
[目的]探索适宜鄂西北低山丘陵区的夏播玉米全程机械化集成生产技术，加快机械化进程，促进鄂西北山地玉米产业发展。[方法]2012—2015年连续开展夏玉米品种筛选试验、播期试验和种植密度试验，筛选适宜鄂西北山区机械化生产的夏玉米品种，研究相应的栽培技术，并结合农机具进行了机械化生产试验，论证其可行性以及评价其生产效益。[结果]筛选出最适宜鄂西北低山丘陵地区夏播玉米机械化生产的玉米品种郑单958，播种时间控制在6月15日前最佳，种植密度为7．50×104株／hm 2最佳。[结论]研究出一套适宜低山丘陵地区的夏播玉米全程机械化生产模式，缓解了当前农村劳动力不足与老龄化问题。
Abstract
Objective]To explore a suitable fully mechanized integrated production technology for the summer sowing maize in low mountain and hilly region of northwest Hubei Province ,promote the process of mechanization and improve the development of northwest mountain maize .[ Meth-od]We screened summer maize varieties, sowing date and planting density of summer corn from 2012 to 2015.Based on the results, to determine the suitable summer maize varieties and the corresponding cultivation techniques in the northwest mountain mechanized production .At the same time, we conducted the production mechanization development , so as to analyze the feasibility of this technology and its production efficiency . [ Result] Zhengdan 958 was suitable for the summer sowing maize production mechanization in low hilly land of northwest Hubei Province .The best sowing time was before June15.The best planting density was 7.5 ×10 4plants per hectare.[Conclusion]We studied mechanized production technology for summer corn in low mountain and hilly region ,which could alleviate the current rural labor shortages and the aging problem.
