山东是灌溉农业大省,也是全国水资源十分紧缺的省份之一。农业是用水大户,占社会总用水量的72.4%,节水有较大潜力。山东是全国主要商品粮生产基地之一,冬小麦总产居全国首位,而冬小麦喷灌具有节水增产、改善农田小气候、提高灌溉水利用系数和水分生产率等明显效果。目前,全省节水灌溉面积已发展到284.1万hm~2,
Shandong is a major agricultural province for irrigation and is also one of the provinces where water resources are scarce in the country. Agriculture is a big user of water, accounting for 72.4% of the total social water consumption, saving more potential. Shandong is one of the country’s major commodity grain production bases with the total winter wheat output ranking the first in the country. The winter wheat sprinkler irrigation has the advantages of water saving and yield increase, microclimate improvement in farmland, and improvement of irrigation water utilization coefficient and water productivity. At present, the province’s water-saving irrigation area has been developed to 2.841 million hm ~ 2,
