【摘要】 针对燕山山麓高产粮区特殊的生态条件及生产中存在的问题 ,1996～ 1999年在河北省遵化市团瓢庄乡进行了冬小麦—夏玉米轮作条件下土壤养分限制因子与排列序谱及高产、高效施肥指标的试验。结果表明 ,在燕山山麓冬小麦—夏玉米轮作条件下 ,冬小麦的养分因子排序为 :N >P >K >S >Mn >Cu >B >Zn ,限制因子为N、P、K、S ,而Zn、Mn、B、Cu则为非限制因子。夏玉米的养分因子排序为 :N >K >P >Zn >Mn >Cu>B >S ,限制因子是N、K、P、Zn、Mn ,非限制因子是S和B。最佳效益施肥量为 :N 45 0kg hm2 ;P2 O5 90～ 12 0kg hm2 ;K2 O 15 0kg hm2 。更多还原

【Abstract】 In view of the special ecological conditions in high yield grain fields at Yanshan foot and production problems, an experiment was conducted from 1996 to 1999 in Tuanpiao town, Zunhua city, Hebei province about soil nutrient factors, their order, and concentrated fertilization index. The study indicates that when winter wheat and summer corn are rotated, order of winter wheat nutrient factors is N>P>K>S>Mn>Cu>B>Zn, and that of restriction factors is N, P, K, S. But order of summer corn nutrient factors is N>K>P>Zn>Mn>Cu>B>S, that of restriction factors is N, K, P, Zn, Mn, that of non restriction factors is S and B. Optimum fertilization is N 450 kg/hm 2, P 2O 5 90～120 kg/hm 2, K 2O 150 kg/hm 2.更多还原
