玉米是河南省的主要粮食作物之一,产量的歉与丰对保障国家粮食安全具有一定的影响。为探索出一条适合玉米种植全程机械化的生产模式,玉米稳产、高产的有效途径,2012年在河南省驻马店市开展了夏玉米免耕机械播种和化肥深施对夏玉米产量影响的对比试验。通过试验,采集并分析了大量的技术数据,为实施免耕机械播种及合理施用化肥提供了科学依据。
Corn is one of the major food crops in Henan Province. The apology and abundance of output have some impact on ensuring the national food security. In order to explore a mechanized production mode suitable for maize planting and an effective way of stable and high-yielding corn, a comparative experiment on the effect of no-tillage mechanical sowing and chemical fertilizer application on summer maize yield was conducted in Zhumadian City, Henan Province in 2012. Through experiments, a large number of technical data were collected and analyzed, providing a scientific basis for sowing tillage machinery and applying fertilizer rationally.
