摘　　要：以光明集团配方肥应用示范基地建设项目为依托,通过设置肥料对比试验探寻适宜上海农场地区的配方肥种类。选择当前上海农场常规水稻品种作为供试品种,于水稻种植期间在上农16队开展配方肥试验,在上海市配方肥推荐目录中,选择适宜上海农场土壤的配方肥,在总氮量一定的情况下,与上海农场常规施肥模式进行对比,通过调整施用量来设置不同的试验处理,比较水稻生长发育及产量效益等确定所选用的配方肥是否适合上海农场地区大面积推广。结果表明,相较于常规复合肥,推荐配方肥在群体、穗粒数以及千粒重方面均有一定的优势,但优势不明显,相较于控失肥,推荐配方肥不能有效地控制施肥节奏,最终效益低于控失肥。因此推荐的配方肥可替代上海农场当前使用的复合肥,但相较于缓控释肥,还有一定的不足。Based on the construction project of Bright Food(Group)Co.,LIT formula fertilizer application demonstration base,the types of formula fertilizer suitable for Shanghai farm area by setting up fertilizer comparison test were explored.The current Shanghai farm routine rice varieties were selected as the tested varieties.During the rice planting period,the formula was tested in the Shanghai farm 16 team.In the recommended list of Shanghai formula fertilizers,the formula fertilizer suitable for the Shanghai farm soil was selected.In the case,compared with the conventional fertilization mode of Shanghai farm,different trial treatments were set by adjusting the application amount,and finally the rice growth and yield benefit and other projects were compared to determine whether the selected formula fertilizer was suitable for large-scale promotion in Shanghai farm area.The results showed that compared with conventional compound fertilizer,the recommended formula fertilizer had certain advantages in terms of population,grain number per panicle and 1 000-grain weight,but the advantage was not obvious.Compared with conventional controlled fertilization,the recommended formulated fertilizer could not effectively control the fertilization rhythm.The benefit was lower than the conventional controlled fertilization.Therefore,the recommended formulated fertilizer can replace the compound fertilizer currently used in Shanghai farms,but there are certain deficiencies compared to the controlled-release fertilizer.
