摘　　要：为探讨玉米在粗放种植管理条件下的产量水平和经济效益。选择了6个适应性较强的玉米品种,在整个生育期中不施用任何肥料,不喷施农药的粗放生产管理条件下,考查玉米品种之间对土壤的生产能力。结果表明桂单0818活杆成熟、果穗长、粒大、折干率较高,经济产量和生物产量极显著最高,经济效益明显。667m^2生物生产力3527.7kg,经济生产力721.70kg,产值2293.28元,纯收益1013.28元。桂单0818是粮食与饲料兼得相对较好的一个品种。To probe the product and economic effect under extension cultivate management condition of maize, 6 varieties have a good adaptability were selected as materials to planted without fertilization and pesticide, then examined the production ability of soil among maize varieties. The results were as follow： Guidan 0818 had many advantages, such as live stem mature, long ear, big kernel, higher drying rate, which had obvious economic benefits because of its supreme economical and biological yield and had a significant at 0.01 level compared with others. The biological and economical productivity were 3527.7 kg/667m2 and 721.7kg/667m2 respeetively, and its production value was reached up to 2293.28 Yuan/667m2 and got 1013.28 Yuan/667m2 as net return.
