摘要
通过对马铃薯品种同薯20号和晋薯15号的根系拉力与冠层覆盖度测试,以及在旱作生态区的适应性试验,对上述2个品种的抗旱性进行了鉴定,结果表明,同薯20号与晋薯15号在干旱胁迫下根系拉力强、冠层覆盖度大、产量水平高、适应性强,是很好的抗旱性品种,可以在全国一季作区及各旱作生态区推广应用。
Through test the root pulling resistance,the canopy cover degrees and the suitability in the dryland ecological region,drought resistance identification of potato variety of the Jinshu 15 and Tongshu 20,was carried out. The results indicated that Tongshu 20 and Jinshu 15 potato showed strong root pulling resistance ,large canopy cover,high yield, strong adaptability ,and they are good drought resistant variety ,which can be popularized in one-season planting region and dryland ecological region in China.
