近来,笔者在走访城郊菜农及农民时发现,实行家庭承包责任制后,由于农民对科学种田知识了解较少,缺乏科学的施肥方法,对承包土地的土质、肥力状况不了解,盲目施肥浪费较大,经济效益下降愈来愈严重.造成农民盲目施肥的原因有以下几方面. Recently, when I visited farmers and peasants in the suburbs, I found that after practicing the family contract responsibility system, farmers have little knowledge of scientific farming practices and lack of scientific methods of fertilization. They do not understand the soil quality and fertility of the contracted land and blindly waste fertilizers Big, economic decline is more and more serious.Was caused by farmers blindly fertilization for the following reasons.
