摘要
通过在河北省石津灌区试验区内开展对冬小麦不同条件下的灌溉模式对比试验,包括水分生产效率和粮食产量等项目,并对井渠结合灌区畦田规格进行试验,包括田畦宽10m和3m两种模式。结果表明,在试验区现状肥力条件下,在中等干旱年墒情充足播种基础上,保证冬小麦产量6 750kg/hm2以上,最佳灌溉定额分别为2 250m3/hm2和2 700m3/hm2;项目区井渠结合适宜的田间畦田规格,田畦长度控制在30～50m,田畦宽度应满足耕作要求,一般可选取3m左右或按当地习惯确定。通过对河北省平原区畦灌技术节水试验模式分析,可为其他类似灌区推广节水灌溉提供参考依据。
Border irrigation is one of the most popular surface irrigation methods.The border irrigation technology in the experimental district is promoted and it found the suitable water-saving border irrigation program,which can improve the water use efficiency and relief the water shortage.Comparative test are taken for winter wheat in different irrigation program in Shijin Irrigation District,including water use efficiency and crop yield.It studied the influence of the side of border with the width of 10m and 3min combined well with canals area.The result shows that the optimum irrigation quotas are 2 250m3/hm2 and 2 700m3/hm2 respectively to ensure the yield above 6 750kg/hm2 in the condition of normal soil fertility,medium drought year and sufficient seeding.The optimum border size should be 30～50mlong and 3mwide.
