近几年来,全国各地普遍反映,化肥肥效有所下降,如何提高化肥增产效率和经济效益是当前的主要课题。我省各地多年来的研究结果表明,化肥的增产效率波动很大,每斤营养成分增产粮食1—2斤到10—20斤。我省每年用肥按160万吨计,其中30%的肥料增产效益只有1—2斤粮食的水平。如果能把这部分化肥的增产率提高到全省目前平均增产率的水平,每年就可多生产6亿斤粮食。
In recent years, it has been generally reported across the country that the fertilizer efficiency has declined, and how to increase the efficiency and economic efficiency of chemical fertilizer production is the current major issue. Over the years, our province’s research results show that the efficiency of chemical fertilizer production fluctuations, grain yield per kilogram of grain 1-2 pounds to 10-20 pounds. The annual output of fertilizer in our province is 1.6 million tons, of which 30% of the fertilizer production efficiency is only 1-2 kg of grain. If we can increase the yield of this part of chemical fertilizer to the current level of the average rate of increase in the province, we can produce 600 million extra kilograms of grain per year.
