Question:什么叫农业节水?Answer:农业节水并非一味地减少用水量,而是为了可持续性地实现一定农业生产目标,高效利用一切可用农业水资源,尽量减少农业用水过程中的一切无效损耗,提高农业水资源转化为农产品的效率。随着人口增加,保障粮食安全已成为世界可持续发展的首要问题,2030年世界人口将达75亿,粮食需求达33亿吨,按现有用水效率计算,农业灌溉用水将增加30%(现有2810立方千米),缺口达750立方千米,水资源短缺已成为全球粮食安全的主要制约因素。缓解粮食增产需求与农业可供
Question: What is agricultural water saving? Answer: Water saving in agriculture is not to reduce water consumption blindly, but to achieve certain agricultural production goals in a sustainable manner, make efficient use of all available agricultural water resources and minimize any inefficiencies in agricultural water use Loss, improve the efficiency of agricultural water resources into agricultural products. As the population increases, ensuring food security has become the most important issue for sustainable development in the world. By 2030, the world’s population will reach 7.5 billion and the demand for food will reach 3.3 billion tons. According to the existing water use efficiency, the agricultural irrigation water will increase by 30% With 2810 cubic kilometers) and a gap of 750 cubic kilometers. The shortage of water resources has become a major constraint on global food security. Ease demand for grain production and supply of agriculture
