小麦是我国主要的粮食作物之一。河南是我国小麦主产区,2011年冬小麦播种面积532.67万hm2,占全国的22.02%。喷灌作为一种现代化的灌溉技术,在我国得到了广泛应用。在小麦产量的诸多影响因素中,水和肥起着十分关键的作用。适宜的灌水可以促进肥料的转化和作物对肥料的吸收利用,提高化肥利用率。而适宜的施肥也可以调节水分利用
Wheat is one of the main food crops in our country. Henan is the main wheat producing area in China. In 2011, the sown area of winter wheat was 5.3267 million hm2, accounting for 22.02% of the national total. Sprinkler irrigation as a modern irrigation technology, has been widely used in our country. Water and fertilizers play a crucial role in many factors affecting wheat yield. Appropriate irrigation can promote the transformation of fertilizers and the absorption and utilization of fertilizers by crops, and improve the fertilizer utilization rate. The appropriate fertilization can also regulate water use
