渭北旱原位于关中川道以北,延安以南,包括23个县(市),1600万亩耕地,其中旱地1450多万亩,南北窄而东西狭长,有旱腰带之称。该区土层深厚,适于小麦生长,麦田面积占总耕地50%以上,商品率高,是我省的粮仓。因此,如何发挥该区优势,坚持三为主(即粮食以夏粮为主,夏粮中以小麦为主,小麦生产以歇茬麦为主)的原则,尽快把小麦生产搞上去,对加快全省农业生产步伐具有重要作用。长期以来,影响这个地区小麦增产的主要问题是干旱和缺肥。实践证明,一般年份只要做好蓄水保墒工作,自然降雨基本可以 Weibei dryland is located north of Guanzhong River, south of Yan’an, including 23 counties (cities), 16 million mu of cultivated land, of which 1450 million mu of dry land, narrow north-south and east-west long, called the belt. This area is deep soil, suitable for wheat growth, wheat fields accounted for more than 50% of the total arable land, high commodity rates, is our granary. Therefore, how to give full play to the advantages of the region, insist on the principle of “three dominate” (that is, the grain is mainly summer grain, the summer grain is mainly wheat and the wheat is mainly wheat grain), and start wheat production as soon as possible, The pace of agricultural production has an important role. For a long time, the main problems affecting wheat yield in this area were drought and lack of fertility. Practice has proved that, as long as the general vintage water and soil moisture conservation work, the basic rainfall can be natural
