摘要
为进一步提高南皮县小麦种植中的水肥利用效率,减少灌溉水用量和肥料施用量,在河北省沧州市南皮县小麦种植区进行大田水肥管理试验,在等施肥量下设置常规施肥、喷灌施肥和浇灌施肥3种灌溉施肥方式。结果表明,喷灌施肥和浇灌施肥可促进小麦的生长,其中喷灌施肥株高和穗鲜重分别比常规施肥处理高11.39%和23.91%。与常规施肥处理相比,喷灌和浇灌施肥千粒重提高3.50%~4.70%,产量提高40.82%~43.36%,水分利用效率提高62.22%~91.85%,肥料偏生产力显著提高。
A field experiment was conducted in Cangzhou,Hubei Province to study the effects of three fertigation methods on growth,yield and water use efficiency of wheat.The results showed that sprinkler and drip fertigation promoted the growth of wheat.Compared to the traditional fertigation,the height and ear fresh weight of wheat increased by 11.39%and 23.91%under sprinkler,and the 1 000-grain weight,yield and water use efficiency increased by 3.50%-4.70%,40.82%-43.36%and 62.22%-91.85%under sprinkler fertigation and flood fertigation,and fertilizer partial productivity significantly improved.
