从八十年代以后,各地施用化肥量有较大幅度增长,平均每亩小麦施用化肥六斤,重点农区达25斤左右。这和其它地区相比,虽然差距很大,但对改善我县土壤缺磷少氮培肥地力,提高生产起着积极作用。由于宣传检查指导不够,不少地方没有注意施用磷肥和掌握施用磷肥的方法,致使土壤氮、磷比例失调。 Since the 1980s, the amount of chemical fertilizers applied has increased by a great margin. Six kilos of chemical fertilizers per mu of wheat are applied on average, and the key agricultural areas are about 25 kilos. This compared with other regions, although a great gap, but to improve my soil phosphorus and nitrogen fertilizers soil fertility, improve production play a positive role. Due to inadequate publicity and inspection guidance, many places did not pay attention to the application of phosphate fertilizer and the method of applying phosphate fertilizer, resulting in the imbalance of nitrogen and phosphorus in soil.
