太行山前平原冬小麦综合节水技术效应分析

Effect of comprehensive water-saving techniques on winter wheat in Talhang Piedmont

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／hm²，水分利用效率达18kg／hm².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／hm²·mm，为太行山前平原实施节水农业提供了科学依据。

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 eficiency(WUE)are achieved．With watel-saving wheat varieties and straw cover． WUE of wheat reachs 24．3kg／hm²·mm．
