缺水是我国面临的最严重问题之一,我国农业用水占总用水量的80%,农业生产最受干旱缺水的困扰,而占农业用水65%以上的水稻生产更是首当其冲,每年均有因旱灾造成的水稻减产,大旱年份减产更多。另外,我国已加入WTO,我省农业将面临国际市场的激烈竞争和挑战。对解决我国21世纪水危机和保障十几亿人口食物充足,减轻国际稻米对我省的冲击,发展节水型稻作(旱作稻)具有重大意义。
Water shortage is one of the most serious problems facing our country. China’s agricultural water accounts for 80% of the total water consumption, and agricultural production is most troubled by drought and water shortage. However, rice production, which accounts for more than 65% of agricultural water use, is even more affected each year Droughts caused by the reduction of rice production, dry years, more production cuts. In addition, China has joined the WTO, agriculture in our province will face fierce competition and challenges in the international market. It is of great significance to solve the water crisis in our country in the 21st century and ensure enough food for billions of people, alleviate the impact of international rice on our province, and develop water-saving rice (dry-type rice).
