增加化肥投入是发展农业生产的一项重要措施。科学地增施化肥,有力地促进了农业生产的发展,既提高了作物产量,又改善了作物品质,而且无机促有机,无机肥和有机肥配合,可以有效地增加土壤有机质,从而提高土壤肥力。施用化肥的技术性强,施肥得当,增产增收,产品品质改善,土壤肥力提高,否则,产品品质恶化,土壤肥力下降。由于土壤、作物、肥料性质的不同,化肥效益受到很大的影响。当前我国化肥的利用率,碳肥不到40％,磷肥不到20％,钾肥50～60％,比国外先进水平一般低10％以上。如果能把我国
Increasing fertilizer input is an important measure for the development of agricultural production. Scientifically increasing chemical fertilizers has effectively promoted the development of agricultural production. It has not only increased crop yields, but also improved crop quality. In addition, organic inorganic, inorganic and organic fertilizers can effectively increase soil organic matter, thereby increasing soil fertility. . The application of chemical fertilizers has strong technical capabilities, proper fertilization, increased production and income, improved product quality, and improved soil fertility. Otherwise, product quality deteriorates and soil fertility decreases. Due to the different nature of soil, crops, and fertilizers, the benefits of fertilizers are greatly affected. At present, the utilization rate of chemical fertilizers in China is less than 40% for carbon fertilizer, less than 20% for phosphate fertilizer, and 50 to 60% for potash fertilizer, which is generally lower than the advanced level in foreign countries by more than 10%.
