【摘要】 在河北省鹿泉市南铜冶村试区实施了工程、农艺等综合节水技术,冬小麦全生育期浇2次水,使小麦产量达7500kg/hm~2,水分利用效率达18kg/hm~2·mm。若种植节水品种、实施秸秆覆盖节水措施,冬小麦水分利用效率可达24.3kg/hm~2·mm,为太行山前平原实施节水农业提供了科学依据。更多还原

【Abstract】 By carrying out comprehensive water-saving techniques such as engineering and agricultural measures in Nantongye experimental region in Luquan City of Hebei Province and irrigating twice during wheat growth period, 7500kg/hm2 yield and 18kg/hm2·mm water use efficiency (WUE) are achieved. With water-saving wheat varieties and straw cover,WUE of wheat reachs 24.3kg/hm2·mm.更多还原
