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 。
In view of the special ecological conditions and production problems in the high-yield grain-growing area of Yanshan Mountain, 1996-1999, the limiting factors and arrangement of soil nutrients under winter wheat-summer maize rotation were studied in Tuanzhuang Village, Zunhua City, Hebei Province. , Efficient fertilization index test. The results showed that under winter wheat-summer maize rotation conditions, the nutrient factors of winter wheat were ranked as N> P> K> S> Mn> Cu> B> Zn and the limiting factors were N, P, K, , Mn, B, Cu is a non-limiting factor. The nutrient factors of summer maize were sorted as N> K> P> Zn> Mn> Cu> B> S, the limiting factors were N, K, P, Zn and Mn, and the unrestricted factors were S and B. The best benefits of fertilizer: N 45 0kg hm2; P2 O5 90 ~ 120kg hm2; K2 O15 0kg hm2.
