我国小麦单产的增加,除了品种改良的作用以外,很大程度上取决于化肥的利用。但是,大量事实表明,在我国目前的粮食生产中普遍存在重视化肥,轻视有机肥的现象,从而导致土壤有机质含量下降、土壤板结、透气性变差,进而影响到产量的进一步提高。该文拟在探讨施化肥(Ｎ、Ｐ)量固定的 The increase of wheat yield in our country depends largely on the utilization of chemical fertilizers, besides the effect of variety improvement. However, a large number of facts show that in the current grain production in our country, there is a widespread phenomenon of emphasis on chemical fertilizers and sloppy organic fertilizers. As a result, soil organic matter content decreases, soil compaction and air permeability deteriorate, further affecting output. This article intends to explore the application of chemical fertilizers (N, P) amount of fixed
