Analysis of the Current Situation of Fertilization and the Reduction and Efficiency of Chemical Fertilizer in Songzi City
Scientific fertilization is an important means and way to improve the quality and efficiency of agricul-ture.In order to protect the fertility of cultivated land,improve the utilization rate of chemical fertilizer,and pro-mote the improvement of agricultural quality and efficiency,the first-hand data were obtained by means of house-hold survey of fixed fields and fixed farmers,and the data of 2006,2021 and 2022 were analyzed.The results showed that the amount of chemical fertilizer used per mu decreased significantly.From 2006 to 2022,the amount of chemical fertilizer per mu decreased by 6.8 kg,with a decline rate of 22.3％;The amount of medium and trace element fertilizers has increased,and the fertilization method has also changed from the traditional spreading method to the mechanical concentrated deep application method.It is proposed that the ways of reducing and in-creasing the efficiency of chemical fertilizers are mainly reflected in four aspects:"refinement,adjustment,modifi-cation and replacement".
