我省配方施肥的重点是东部农业区川水、浅山、脑山三个自然区,作物以粮、油为主。为了进一步探讨各地区当前土壤肥力条件下,氮、磷、钾化肥的肥效、有机肥与化肥配合施用的增产效果、肥料利用率、土壤供肥量等参数,以验证配方施肥的有关资料,因此安排了以下试验。 The key points of formula fertilization in our province are the three natural areas of Chuanshui, Shallow Hill and Beishan in the eastern agricultural area. The crops are mainly grain and oil. In order to further explore the fertility of nitrogen, phosphorus and potassium fertilizers, yield increasing effect of organic manure and chemical fertilizers, fertilizer use efficiency, soil available fertilizer and other parameters under the current soil fertility conditions in various regions to verify the information about formula fertilization, The following test was arranged.
