黑龙江省地域辽阔、土地资源丰富,农业增产潜力很大。国营农场在农业经济中占有重要地位,机械化程度高。化肥在这种条件下对粮食增产具有重要作用,每年大约有30—50亿斤粮食来源于化肥的增产。因此,逐年增加化肥施用量,不断改进施肥技术、提高化肥的增产效果,对于实现农业现代化具有重要意义。我省化肥增产率较低,全省平均每斤氮素约增产粮食7—10斤,最高增产20斤
Heilongjiang Province has a vast territory with rich land resources and great potential for increasing agricultural output. State-owned farms occupy an important position in the agricultural economy and have a high degree of mechanization. Under such conditions, chemical fertilizers play an important role in increasing grain output. Each year, about 3 to 5 billion kilograms of grain comes from the increase of chemical fertilizers. Therefore, it is of great significance for the modernization of agriculture to increase the amount of chemical fertilizers every year, continuously improve fertilization techniques and increase the yield of chemical fertilizers. Fertilizer yield increase in our province is lower, the province’s average yield of about 7-10 kg of nitrogen per kilogram of grain, the highest increase of 20 kg
