结合内蒙古自治区玉米生产实际,于2011~2013年进行了玉米不同种植模式定位试验,通过连续3年对植株生长发育、产量构成及经济效益等指标测定及分析。结果表明:高产高效模式通过多因素调控,土壤环境、种植密度和肥料配比为玉米提供良好的生长条件,玉米叶面积指数,单位面积干物质积累量各生育时期均高于农户模式和无肥模式;产量数据表明,高产高效模式3年平均比农户模式和无肥模式分别增产13.7%、35.7%,多增加收入776.05元/hm2、1732.64元/hm2。
According to the actual maize production in Inner Mongolia Autonomous Region, different planting patterns of maize were tested in 2011-2013. The growth and development, yield components, economic benefits and other indexes of maize were determined and analyzed for three consecutive years. The results showed that high yield and high efficiency model provided good growth conditions for maize through multi-factor regulation, soil environment, planting density and fertilizer ratio. The leaf area index and dry matter accumulation per unit area of maize were higher than those of peasant households The yield data showed that the high-yield and high-efficiency model increased 13.7% and 35.7% respectively over the three-year average of farmers and non-fertilization modes, and increased the income by 776.05 yuan / hm2 and 17,332.64 yuan / hm2.
