    摘要:

    为了解河北平原冬小麦、夏玉米农田基础产量状况,提高养分管理水平,对2011~2014年在河北省开展的894组小麦和952组玉米配方施肥农户示范数据进行了分析,评价了河北省冬小麦、夏玉米农田施肥量、基础产量、施肥产量、养分效率和地力贡献率。结果发现,河北冬小麦、夏玉米平均施氮(N)量分别为242和234 kg/hm2,施磷(P2O5)量分别为65和59 kg/hm2,施钾(K2O)量分别为45和61 kg/hm2;冬小麦、夏玉米平均农田基础产量分别为4 509和5 979 kg/hm2,农民习惯施肥平均产量分别为6 390和7 905 kg/hm2;氮肥偏生产力分别平均为25.3和39.9 kg/kg,磷肥偏生产力平均为47.3和115.2 kg/kg,钾肥偏生产力平均为102.9和136.0 kg/kg。河北平原冬小麦、夏玉米的农田基础产量贡献率平均为70.6%和71.6%,农田地力贡献率随着基础产量水平的提高呈显著提高趋势,基础产量与施肥产量呈极显著线性相关关系。提高基础产量水平是保证河北省冬小麦、夏玉米高产的关键。

    Abstract:

    In order to understand the soil basic yield and percentage of basic soil fertility contribution(PBSFC)to winter wheat and summer maize in Hebei plain,a dataset include 894 wheat and 952 maize demonstration experiments,which were conducted by the National Soil Testing and Formulated Fertilization Project in Hebei Province,was built to evaluate the farmers’ fertilization rates,basic yield,fertilization yield,nutrient use efficiency and percentage of soil fertility contribution.The results showed that the averaged farmers’ fertilizer input of wheat and maize for N was 242 and 234 kg/hm2,respectively; for P2O5 was 65 and 59 kg/hm2,respectively; for K2O was 45 and 61 kg/hm2,respectively.The averaged basic yield of wheat and maize was 4 509 and 5 979 kg/hm2,respectively; while the farmers’ fertilization yield was 6 390 and 7 905 kg/hm2,respectively.The partial fertilizer productivity(PFP)of wheat and maize for N was 25.3 and 39.9 kg/kg,respectively; for P was 47.3 and 1152 kg/kg,respectively; for K was 102.9 and 136.0 kg/kg,respectively.The averaged percentage of basic soil fertility contribution for wheat and maize in Hebei plain was 70.6% and 71.6%,respectively.The PBSFC significantly increased with the basic yield level increasing,and the fertilization yield significant linearly correlated with the basic yield.This research indicated that the increasing the basic yield was the key factor which guaranteed the high yield of winter wheat and summer maize in the Hebei plain.
