摘　　要：试验选择红壤旱地上不同培肥措施的土壤,分别代表不同肥力水平的土壤:即荒地土(低肥力)、茶园土(中肥力1)、花生地(中肥力2)和菜园土(高肥力),通过设置施肥与不施肥盆栽试验,研究不同肥力水平红壤旱地的基础地力贡献率和肥料贡献率。结果表明:施肥可以显著提高玉米产量,各肥力水平的玉米产量的变化趋势为菜园土>花生地>茶园土>荒地土,在红壤旱地上,有机培肥措施不仅可以提高作物产量,而且可以提高土壤肥力和基础地力对产量的贡献率。The experiment selected the soil with different fertilization measures on dry land of red soil,the soil representing differentfertility levels such as uncultivated soil(low fertility),tea garden soil(medium fertility),peanut fields soil(medium fertility)and vegetablefield soil(high fertility),based on the experiment of fertilization and non-fertilization,the basal soil fertility contribution rate and fertilizercontribution rate of red soil dry land with different fertility levels were studied.The results showed that fertilization could increase maizeyield significantly,the trend of corn yield in each fertility level was vegetable field soil>peanut field soil>tea garden soil>uncultivatedsoil,in red soil dry land,organic fertilization measures can not only increase crop yield,but also improve soil fertility and contribution rateof basic soil fertility to yield.
