永寿县位于渭北旱原西部,主产小麦。据近33年统计,全县年种植小麦31.9万亩,占粮田总面积的55.5％,产量4109.95万斤,占粮食总产的53.4％。当前,影响小麦大面积稳产高产的突出问题是干旱、地力瘠薄和耕作栽培粗放。三者相互交错,成为旱地小麦急待解决的问题。一、干旱问题从历年看,永寿地区降水量并不算少,年降水量298.2—853.8毫米,平均600毫米左右。属于半干旱半湿润过渡地区。科学试验说明,在土壤肥力较好的条件下,每生产1斤小麦,只需消耗0.7—1.0毫米的降水,这样估计,常年亩产小麦可达400—500斤,甚或更 Yongshou County is located in the western part of Weibei drylands, the main production of wheat. Nearly 33 years of statistics, the county planted 319,000 acres of wheat, accounting for 55.5% of the total area of ​​grain, output 41,099,500 kg, accounting for 53.4% ​​of total grain output. At present, the prominent problems that affect the steady and high yield of wheat in large areas are drought, poor land fertility and extensive cultivation and cultivation. The three intertwined, a drought of wheat urgent problem. First, the drought problem From the calendar year, Yongshou area precipitation is not less, the annual rainfall of 298.2-853.8 mm, an average of about 600 mm. Semi-arid and semi-humid transitional areas. Scientific experiments show that under the condition of better soil fertility, each kilogram of wheat produced consumes only 0.7-1.0 millimeters of precipitation. In this way, the annual output of wheat per year can reach 400-500 kilos, or even more
