在我国农业生产中,水资源紧缺问题越来越突出。我国现有耕地中灌溉面积9.25亿亩、旱作近10亿亩,年灌溉用水3600亿方、缺口300亿方,每年受灾面积高达4~5亿亩、损失粮食600亿斤。以国产卷盘式喷灌机为代表的节水灌溉装备成为实现水资源高效利用,化解地下水超采危机,降低农业劳动成本,保证我国农业可持续发展的战略选择。
In China’s agricultural production, the issue of water shortage is more and more prominent. China currently has 925 million mu of irrigated land, nearly 1 billion hectares of dry land, 360 billion cubic meters of irrigated water a year, a 30 billion-square-foot gap and an area of 400-500 million mu each year, with a loss of 600 billion jin of grain. Water-saving irrigation equipment represented by domestic reel-type irrigation machines has become a strategic choice for realizing efficient utilization of water resources, resolving the crisis of over-exploitation of groundwater, lowering agricultural labor costs and ensuring the sustainable development of agriculture in China.
