摘　　要：以油肥1号、沣甜糯1号为材料,研究薹肥兼用油菜翻压还田对双季鲜食玉米产量及土壤养分的影响,并对薹肥兼用油菜—双季鲜食玉米种植模式的经济效益进行分析。结果表明,与对照相比,油菜翻压还田,土壤中有机质、碱解氮、速效钾、全磷及有效磷含量均显著提高,分别提高了30.9%、3.9%、17.3%、16.7%和15.2%;后茬双季鲜食玉米产量也显著提高,鲜穗总产量达到20 023 kg/hm^(2),增产17.49%;通过新增一季菜薹,该模式总产值可达189 434元/hm^(2),经济效益显著提高。The overturning effect of combination of bolting and fertilizer rapeseed on the yield of double-cropping fresh corn and soil nutrients was studied using Youfei No.1 and Fengtiannuo No.1 as test materials,and the economic benefits of the planting pattern of double-cropping fresh corn and combination of bolting and fertilizer rapeseed were analyzed.Compared with the control,the contents of organic matter,alkali hydrolyzable nitrogen,rapidly available potassium,total phosphorus and available phosphorus in the overturning soil of rapeseed were significantly increased by 30.9%,3.9%,17.3%,16.7%and 15.2%,respectively.The yield of double-cropping fresh corn was significantly improved,and the yield of total fresh ear reached 20023 kg/hm^(2),an increase of 17.49%compared with the control.By adding another season of flowering Chinese cabbage,the overall output value of this planting pattern reached 189434 yuan/hm^(2) with significant improvement in economic benefits.
