阿合奇县地处高寒山区。海拔1730～5958米,气候寒冷,热量不足,无霜期150～165天,≥10℃有效积温2500～2600℃只能满足一年一熟小麦、油料、蚕豆和苜蓿等作物的热量需要。县农技推广站1998年8月,从自治区农科院引进新冬17号、19号、16号、18号和奎冬5号等5个冬麦品种进行品比试验,选定新冬17号作为推广品种。至今已4年之久,现将栽培技术要点总结如下。 一、新冬17号试验推广情况 1998年8月引进新冬17号等5个品种进行多点试验。试验结果表明,新冬17号的综合表现最好,单产高达617公斤/666.7米~2,比当地品种高出345公斤,增幅达67％,因此确定为推广品种。新冬17号不但适应性强、单产高,还有较强的抗寒、抗病、抗灾能力,荒地、草地、新开地都能增产,深受广大农牧民欢迎。 Alchic County is located in the alpine mountains. Elevation 1730 ~ 5958 meters, cold climate, lack of heat, frost-free period of 150 to 165 days, ≥ 10 ℃ effective accumulated temperature of 2500 ~ 2600 ℃ can only meet the one-year cooked wheat, oil, beans and alfalfa and other crops caloric needs. County Agricultural Extension Station August 1998, from the Academy of Agricultural Sciences introduced new winter 17, 19, 16, 18 and Kui Dong 5 winter wheat varieties such as five ratio test, the selection of new winter 17 No. as a promotion of varieties. It has been 4 years, now the cultivation techniques summarized as follows. First, the promotion of the experiment of Xin Dong 17 In 1998 August the introduction of Xin Dong 17 and other 5 varieties of multi-point test. The results showed that the comprehensive performance of Xin Dong 17 was the best, with a yield of 617 kg / 666.7 m ~ 2, 345 kg more than that of the local variety, an increase of 67%. Therefore, it was identified as a promotion variety. Xin Dong 17 not only adaptable, high yield, there are strong cold, disease resistance, resilience, wasteland, grassland, newly opened can increase production, welcomed by the majority of farmers and herdsmen.
