摘要
1986～1989连续四年,采用大麦改良品种与小麦现代主栽品种在盆地丘陵典型的土壤生态位进行了不同密度、不同施肥水平的复杂裂区设计的产量对比试验.确认大麦的产量潜力显著高于小麦,分析了相应的作物生理学基础.提出了调整四川盆地麦类生产布局、开发大麦生产,促全省粮食、饲料生产再上新台阶的建议.
Improved barley cultivars and local commerciallygrown wheat cultivars were planted on typical soil ecological niches in the hilly regions of Sichuan Basin in 1986-1989. A split-split-plot design was utilized with different Plant densities and fertilizer rates. It was prooved that yield potentials of the barley cultivars tested were significantly higher than those of wheat cultivars. The Physiological base of yield increase of barley was discussed. A Proposals concerning the readjustment of the geological distribution pattern of barley and wheat and the extension of barley cultivated area, thus promoting the grain and forage production of Sichuan Province to a higher level Were offered.
