选育和推广早地小麦新品种是提高旱地小麦产量一项投资小、耗能低、见效快的增产技术措施。观察研究旱地小麦的某些特点,对引种、生态育种,品种合理布局等工作有一定的意义。我县半干旱地区(中、高位浅山),海拔在2300—2700米,年平均温度3—4℃,年降雨量400—500毫米,≥0℃积温1700—2000℃,作物生长季为150—170天一年一作。该地区小麦种植面积35万亩左右,约占我县小麦面积的80％,旱地小麦产量丰欠与否,对我县小麦产量影响很大。
Breeding and promotion of early wheat varieties is an investment in dryland to increase wheat yield a small investment, low energy consumption, quick increase yield technical measures. Observing and studying some characteristics of dryland wheat is of certain significance to the introduction, ecological breeding and rational distribution of varieties. Arid areas in our county (middle and high shallow mountain), elevation of 2300-2700 meters, the annual average temperature of 3-4 ℃, the annual rainfall of 400-500 mm, ≥ 0 ℃ accumulated temperature of 1700-2000 ℃, crop growth season for the 150- 170 days a year for the work. The area of 350,000 acres of wheat planted in the region, accounting for about 80% of the area of wheat in my county, dry or insufficient production of wheat, wheat yield in our county a great impact.
