对两个抗旱性强的旱地小麦品种和一个抗旱性弱的水地品种,在不同水肥条件下进行了生态生理学的系统比较研究。结果表明,两个旱地品种分别属于御旱力较强的旱肥型和耐旱力较强的旱薄型。它们各自形成的系统发育条件和适应干旱的方式有所不同。在黄土旱塬地区。抗旱育种指标应着重于御旱性状,各项耕作栽培措施应紧紧围绕“种好”、促进种子根下扎、培育壮苗这一中心环节。鉴定抗旱性的田间试验应采用水肥双重控制法。
Two ecotype physiological and physiological studies were conducted on two drought-tolerant wheat cultivars and one drought-resistant water cultivar under different water and fertilizer conditions. The results showed that the two dryland cultivars belonged to drought-type with stronger drought-resistance and drought-thin with stronger drought-resistance. Their respective phylogenetic conditions and adaptation to drought are different. In the loess plateau area. Drought resistance breeding indicators should focus on the drought-resistant traits, the cultivation and cultivation measures should be closely around the “good”, and promote seedling root bar, nurturing strong seedlings of this central aspect. Field trials to identify drought resistance should be doubled with water and fertilizer control method.
