地处乌蒙之巅的威宁县由于受海拔高、气候冷凉、耕地细碎分散和土地石漠化严重等因素的制约，导致玉米种植产量长期较低。通过实地试验，以寻求适合威宁县种植和推广的玉米良种。结果表明：同时施用农家肥与复合肥，临奥4号的生育期最短，为148d；产量最高，为8720．0kg／hm2；经济效益最佳，为11178．0元／hm2。因此，可在威宁地区推广种植临奥4号，同时施用农家肥与复合肥，可获得明显的增产、增收效果。

Weining County Located in the top of the Wumeng,with the high altitudes, cold climate,land fragmentation,land rocky desertification severe crushing and other factors ,so that the corn yield was low in long term. In this paper,based on field trial ,improved varieties suited to cultivation and promotion were studied in Weining County.The experiment results showed that the growth period of Linao 4 was shorter under applying farmyard manure and compound fertilizer,it was 148 days;with the higher yield was 8 720.0 kg/hm2,the optimal economic benefits was 11 178.0 yuan/hm2, Consequently,plant Linao 4 in Weining area, use farmyard manure and compound fertilizer,it will increase production and benefit obviously.
