玉米宽窄行栽培是一种保护性耕作方式,为了大面积推广应用宽窄行栽培技术,2012年在我镇试验基地对该项技术进行了试验,品种选择了郑单958,探索在不同密度和不同施肥水平条件下其产量表现,从中筛选出该品种适宜的密度及施肥水平,确定出相应的高产配套栽培技术,为指导全县农业生产提供可靠的科学依据。1.材料与方法1.1供试品种供试品种为郑单958。1.2试验设计与方法(1)密度:设为4个处理,即5万株/公顷、6万株/公顷、7万株/公 Corn width and width row cultivation is a kind of conservation tillage. In order to popularize wide and narrow row cultivation techniques for large area, this technique was tested in our town base in 2012. The variety chose Zhengdan 958 to explore different density and different Fertilization level under the conditions of its performance, from which screening of the appropriate species of the density and fertilization levels to determine the appropriate high-yielding cultivation techniques to guide the county’s agricultural production to provide a reliable scientific basis. 1. Materials and methods 1.1 Test varieties for the test varieties Zhengdan 958.1.2 Experimental Design and Methods (1) Density: set to 4 treatments, namely 50000 plants / hectare, 60,000 plants / hectare, 70,000 plants / public
