文摘This paper first described the current status of wheat nitrogen fertilizers utilization rate. Then,from balanced fertilizer application,applying slow/controlled release fertilizer,deep application of nitrogen fertilizers and graded application,controlled application amount,selection of application time according to soil properties,diagnosed application of fertilizer with instrument,addition of synergist,and precise fertilizer application,it summarized biological nitrogen saving methods and introduced prospects of future biological nitrogen saving technology.
