摘　　要：在冀西北半干旱高寒区的两种不同的土壤中,进行饲用玉米产量表现的研究.结果表明,玉米的产量滩地明显高于沙地.沙地追氮对饲用青玉米有明显增产效果,而滩地追氮对饲用青玉米没有明显增产效果.Yields of forage maize were studied in two kinds of soils in JI Northwest Dryland. The result showed that yield of forage Maize in medium loam meadow chestnut soil was higher than that in sandy chestnut soil. The result also showed that yield was obviously increased after nitrogen application in sandy chestnut soil, but not effectively in medium loam meadow chestnut soil.
