小麦省水灌溉试验研究,在于探索省水而又减产程度不大的灌溉技术。试验地前茬为谷子,肥力中等(耕层土壤全氮量为0.79—1.02%,含有机质1%左右),壤土,田间持水量25.4%,供试品种为偃大25。试验设8个处理(表1),重复两次,小区长13.5米,宽4.5米(3畦),面积为0.91分。各处理间设保护区一畦,宽1.1米。 Experimental research on water-saving irrigation in wheat is to explore irrigation technologies that reduce water consumption and reduce production to a lesser extent. The former crop was millet with medium fertility (0.79-1.02% total nitrogen content in topsoil and 1% organic matter content), and the loamy and field water content was 25.4%. The tested variety was Yan 25. The experiment set 8 treatments (Table 1), repeated twice, the cell length of 13.5 meters, 4.5 meters wide (3 畦), an area of ​​0.91 points. Protected area between the treatment of a 畦, 1.1 meters wide.
