前几年,我镇大多数村重用地轻养地,重视氮化肥忽视磷、钾肥和有机肥,从而导致土壤有机质含量降低,氮磷钾比例严重失调,出现了粮食产量徘徊不前的局面。自1987年,通过小麦、玉米秸秆还田和小麦高留茬等措施,逐渐培肥了地力,提高了产量。我镇秸杆还田面积已达4.4万亩,增产粮食325.6万公斤,增加经济 A few years ago, most villages in my town re-used land lightly and emphasized the neglect of phosphorus, potassium and organic fertilizers by nitrogenous fertilizers. As a result, the content of organic matter in the soil was reduced and the proportion of nitrogen, phosphorus and potassium was seriously imbalanced. As a result, the grain output stagnated. Since 1987, wheat, corn stalks and wheat stubble and other measures to gradually fertilize the fertility and increase production. My town straw field has reached 44,000 mu, an increase of 325.6 million kilograms of grain, increase the economy
