我社东山大队1976年购买40多吨过磷酸钙,用它与碳酸氢铵或氨水制成氮化过磷酸钙,群众叫磷固氮。用磷固氮给1,000多亩玉米、高粱、谷子、大豆等作物作口肥和追肥,增产效果很好。去年虽然遇到低温等严重自然灾害,但全大队粮谷作物平均亩产624斤,比1975年增产87％。一队玉米随播种亩施磷固氮30斤作口肥,平均亩产620斤,比亩施碳酸氢铵20斤增产24％。
Our company Dongshan Brigade purchased more than 40 tons of superphosphate in 1976, and made it into nitriding superphosphate with ammonium bicarbonate or ammonia. The masses called phosphorus nitrogen fixation. Phosphorus nitrogen fixation to more than 1,000 acres of corn, sorghum, millet, soybeans and other crops as fertilizer and top dressing fertilizer, yield is good. Although it encountered serious natural disasters such as cold weather last year, the entire grain production of whole-grain cereal crops has averaged 624 kilograms per mu, an increase of 87% over 1975. A team of maize sowing phosphorus and nitrogen fixation 30 kg as mouth fat, the average yield of 620 kg, 20 kg more than the output of ammonium bicarbonate Mushu yield 24%.
