摘要
为探寻德州地区玉米种植适宜的施肥模式,开展了田间试验,设置4个不同的施肥模式,比较了不同施肥模式对玉米产量、品质和种植经济效益的影响。结果表明,减氮0%~20%,控释肥与尿素配施提升玉米种植经济效益,特别是减氮20%时,经济效益最高。总体来说,氮肥减施20%条件下,控释肥与尿素配施是德州地区玉米种植适宜的施肥模式。
In order to explore the appropriate fertilization pattern for maize planting in Dezhou,a field experiment was conducted.Four different fertilization patterns were set up to compare the effects of different fertilization patterns on maize yield,quality and planting economic benefits.The results showed that under the condition of 0%~20% reduction of nitrogen fertilizer,controlled release fertilizer and urea combined application can improve the economic benefit of maize planting,especially when nitrogen reduction of 20%,the economic benefit is the highest.In general,combined application of controlled release fertilizer and urea is the suitable fertilization pattern of Maize Plant in Dezhou area under the condition of 20% reduction of nitrogen application.
