摘　　要：连续８年的试验进一步表明，渭北旱地小麦仍有巨大的生产潜力。采用以水肥高效利用为中心的高效节水耕作法，选用抗旱高产良种，实行科学配方施肥，适期播种培育壮苗，建立合理的群体结构等综合配套技术，就可使旱地小麦蕴藏的生产潜力得以挖掘，在１０年中，至少有７年产量可达６０００ｋｇ／ｈｍ２，丰水年达７５００ｋｇ／ｈｍ２以上。An eight year study shows that the wheat on Weibei dryland has the tremendous potential productivity. If the comprehensive perfection techniques of high efficient water save tillage method centered around the high effective fertilizer utilization, the selection of drought resistant and high yield varieties, the practice of scientifically prepared fertilizers, the suitability of sowing period,the cultivation of robust seedling, and the establishment of rational population structure are adopted, the potential productivity of dryland wheat can be tapped. At least 7 out of 10 years, a yield of 6000 kg/hm 2 in normal rainfall years and 7500 kg/hm 2 in rich rainfall years can be reached.
