一、试验研究方法为了筛选适宜夏播的小麦品种,我们自1981—1983三年先后从各地广泛征集了国内外春小麦品种资源723个。在夏播小麦适宜栽培地区,海拔为1000公尺的丘陵旱地,选择了太原市北郊区丈子头公社丈子头大队进行引种观察试验。当地因春旱比较严重,冬、春小麦产量极不稳定,丰收年亩产仅百斤左右。夏播小麦可以躲过春旱,充分利用夏秋降雨。太原7月上旬 First, the experimental research methods In order to screen suitable summer sowing wheat varieties, we from 1981-1983 three years has from all over the extensive collection of domestic and foreign spring wheat varieties 723 resources. In summer sowing wheat suitable cultivation area, elevation of 1,000 meters hilly drylands, chose the northern suburb of Taiyuan Zhangzitou commune Zhangzitou brigade introduction test. Due to the severe drought in spring, the output of wheat in winter and spring is extremely unstable. Summer broadcast wheat can escape the spring drought, take full advantage of summer and autumn rainfall. Taiyuan in early July
