本试验采用田间鉴定法,两年来通过对12个不同莜麦品种(品系),在不同生育时期的抗旱形态指标、抗旱生理指标和丰产性状等指标的测定,经过多方面比较,综合分析,肯定了高8—21、高8—25、578、7413、华北二号等为抗旱性强,经济性状表现好的品种,是目前我区旱地莜麦良种不足,产量不高情况下,最适宜于内蒙西部旱作区推广、应用的优良品种,该品种随着生产上的使用,对提高我区莜麦产量,将会有着积极作用。 In this experiment, the method of field appraisal was adopted. In the past two years, the determination of 12 drought-resistant morphological indexes, physiological indexes of drought resistance and high yield traits at different growth stages was conducted through the comparison and comprehensive analysis of 12 different varieties of 莜 varieties (lines) High 8-21, high 8-25,578,7413, North China II, such as drought-resistant, good economic performance of the varieties, is the lack of wheat in the dry land in our area, yield is not high, the most appropriate Inner Mongolia, arid areas to promote the use of fine varieties, with the use of the variety of production, to improve the yield of oats in our region, will have a positive effect.
