从参加复合肥料生产技术国际研讨班的22个国家农业国情,分析近10年来世界人口、粮食、肥料生产与消费情况,提出应注意提高肥料利用率,发展缓释肥料,并应正确估价化肥的作用。要采取正确施肥、合理的灌溉技术、改良土壤、繁殖根系发达和耐肥的作物品种、加强田间管理等措施提高谷物的单产
From the national conditions of 22 countries participating in the International Workshop on Compound Fertilizer Production Technology, we analyzed the situation of world population, food, and fertilizer production and consumption in the past 10 years and proposed that attention should be paid to increasing fertilizer use efficiency, developing slow-release fertilizers, and correctly assessing chemical fertilizers. effect. We must adopt measures such as proper fertilization, reasonable irrigation techniques, soil improvement, breeding of developed root systems and fertilizer-resistant crop varieties, and strengthening of field management to increase the yield of cereals.
