我国是世界上水资源贫乏的国家之一,特别是北方地区耕地面积占全国的45%,但水资源仅占全国总量的9.7%,以全国第三产粮大省河北为例,用占全国0.7%的水生产了全国6%的粮食,养育了全国5%的人口。但这是以严重超采地下水为代价换来的。所以依靠科技的力量大力发展节水农业日益重要。农业节水以成为当今社会十分关注的热点问题,本文将浅要谈谈我国农业的节水技术。
China is one of the countries with poor water resources in the world. Especially in the northern region, cultivated land accounts for 45% of the country’s total. However, water resources account for only 9.7% of the national total. Taking Hebei as the third largest grain-producing province in China as an example, About 0.7% of the country’s water produced 6% of the country’s food and raised 5% of the country’s population. But this is in exchange for a serious over-exploitation of groundwater. Therefore, relying on the power of science and technology to develop water-saving agriculture is increasingly important. To save water in agriculture has become a hot issue that pays close attention to in today’s society. This article will briefly talk about the water saving technologies of agriculture in our country.
