80年代随着农业生产水平的提高和化肥用量的增加,确定合理施肥已成为施肥技术中的核心。对施肥技术的要求也有了很大的提高,从使用单一肥料发展到多种营养元素配合施用,凭经验施肥已不能适应生产要求,必须改变常规的用肥量和施肥方式,现已在生产实践中找到了最佳“配方施肥技术”.所谓配方施肥是综合运用现代化科技成果,根据作物生长规律、土壤供肥性与肥料效应,在已有有机肥为基础的条件下,产前提出氮、磷、钾和微肥的适宜用量和比例.
In the 1980s, with the improvement of agricultural production and the increase of the amount of chemical fertilizers, the rational fertilization has become the core of fertilization technology. The requirements of fertilizer technology has also been greatly improved from the use of a single fertilizer to the development of a variety of nutrients with the application of fertilization by experience has been unable to meet the production requirements must change the conventional amount of fertilizer and fertilization methods are now in production practice Found the best “formula fertilizer technology.” The so-called formula fertilization is the comprehensive utilization of modern scientific and technological achievements, according to crop growth law, soil fertility and fertilizer effect, in the existing organic fertilizer-based conditions, prenatal nitrogen, Appropriate amount and proportion of phosphorus, potassium and trace fertilizer.
