随着农业生产的发展和栽培技术水平的提高,化肥推广使用在我区有了很大的发展,对提高粮食产量起了重要作用。1970年全区氮,磷化肥总施用量为36625吨,平均每亩施肥量为17.5斤,1976年全区氮、磷化肥总施用量增加到137040吨,平均每亩施肥量为59.2斤。1976年以后,每年化肥用量均在13万吨左右。1980年全区粮食总产量达到14.6亿斤,比1979
With the development of agricultural production and the improvement of cultivation techniques, the promotion and use of chemical fertilizers have made great progress in our region and played an important role in raising grain output. In 1970, the total nitrogen and phosphorus fertilizer application volume was 36,625 tons and the average amount of fertilizer per acre was 17.5 kg. In 1976, the total nitrogen and phosphorus fertilizer application rate in the region increased to 137,040 tons and the average amount of fertilizer per acre was 59.2 kg. After 1976, the annual amount of fertilizer is about 130,000 tons. In 1980, the total grain output in the region reached 1.46 billion kilograms, more than in 1979
