我县自1978年开始,推广施用氨化过磷酸钙,使粮、棉、油连续三年获得丰收。自制的氮、磷复合化学肥料—氨化过磷酸钙,是用碳酸氢铵或氨水氮化处理过磷酸钙而获得。1978年全县各社队自制氨化过磷酸钙2万多吨,至1980年达4万多吨。在粮、豆面积连年减少的情况下,平均每年以增产4千多万斤的幅度递增。在1980年,虽然遭受干旱,病虫等多种自然灾害,但粮、棉、油仍获得全面丰收。粮豆总产量达4亿多斤,比1979年增产6千多万斤;粮豆单产达597斤,比1979年每亩增加123斤。皮棉总产1.3万担,比1979年增加4.4千担;单产91斤,比1979年增加44斤。花生总
Since 1978, our county has promoted the use of ammoniated superphosphate to make the harvest of grain, cotton and oil three consecutive years. Homemade nitrogen and phosphorus compound chemical fertilizer - ammoniated superphosphate, ammonium bicarbonate or ammonia nitrogen is treated with superphosphate obtained. In 1978, the community-owned teams made more than 20,000 tons of ammoniated calcium perphosphate to more than 40,000 tons in 1980. In the case of food and bean area declining year by year, the average annual increase rate of more than 4 million kilograms has been increasing. In 1980, despite various natural disasters such as droughts, pests and diseases, the overall harvest of grain, cotton and oil was still abundant. The total output of grain beans reached 400 million kilos, an increase of more than 6 million kilograms more than in 1979; the yield of grain beans reached 597 kilos, an increase of 123 pounds per mu in 1979. The total output of lint cotton was 13,000, an increase of 4.4 kilograms over 1979; the yield was 91 pounds, 44 kilograms more than in 1979. Peanuts always
