农业是第一用水大户,占全社会用水总量的55%以上,而水稻又是我国用水量最多的粮食作物,水稻灌溉消耗了大量的水资源,特别是传统的淹灌加剧了水资源短缺的矛盾。水稻田滞蓄能力不足,灌水过多,排水沟缺乏控制,直接导致稻田大量排水,田间肥料和农药随之流失和扩散,引起了比较严重的水体及土壤污染。稻田布局不合理,规格偏小,生产效率低,增加了农业生产成本,严重制约了农村发展新型现代化农业及农业的国际竞争力。本项目以节水、控排、提高耕作效率为
Agriculture is the largest water user, accounting for more than 55% of the total water consumption of the whole society. However, rice is also the most water-consuming food crop in our country. Rice irrigation consumes a large amount of water resources, especially traditional flooding aggravates the shortage of water resources Contradictions. Paddy storage capacity is insufficient, excessive irrigation, lack of drainage ditch control, leading to a large number of paddy drainage, fertilizers and pesticides along with the field loss and proliferation, causing more serious water and soil pollution. Irrational layout of paddy fields, small specifications, low productivity and increased agricultural production costs have seriously hampered the rural development of new modern agriculture and agriculture in the international competitiveness. This project is to save water, control row and raise tillage efficiency
