河南省唐河地区在小麦施肥应用的过程中经历了4个阶段,一是只施土肥,产量150kg/667m2;二是单一施氮肥,产量250kg/667m2;三是氮、磷、钾配合,单产350kg/667m2;四是科学配方施肥,产量450kg/667m2。近几年,虽然通过培育良种、改善生产条件,但是产量≤600kg/667m2。为了创造更高的产量,采用施用硅钾基复混肥,结果使小麦产量平均达到606kg/667m2,个别地块达794kg/667m2。
The application of wheat fertilization in Tanghe area of Henan province has gone through four stages. The first one is soil fertilization only, the output is 150kg / 667m2. The second one is single application of nitrogen fertilizer with the yield of 250kg / 667m2. The third is the combination of nitrogen, phosphorus and potassium, yield 350kg / 667m2; Fourth, scientific formula fertilization, yield 450kg / 667m2. In recent years, although the breeding conditions have been improved to improve the production conditions, the yield is ≤600kg / 667m2. In order to create higher yields, the use of Si-K based fertilizers resulted in an average wheat yield of 606 kg / 667 m2 and individual lots of 794 kg / 667 m2.
