【摘要】 在小麦条锈病核心越夏区对比试验结果表明,小麦收获后翻耕,具有降低自生麦苗密度、推迟生育期、降低条锈病发生程度,从而减少条锈病越夏菌源,降低秋苗发病程度的作用。相比较而言,机械翻耕比畜力翻耕的作用更明显,延迟到麦收后30d翻耕比传统的麦收后10d翻耕的作用更明显,翻耕后镇压耙磨有时表现有降低发病的作用。根据临夏地区特点,小麦收获后30d左右、冬小麦播种前应进行耕翻,在平川麦区应加大机耕推广力度。考虑到耙磨还有保墒作用,翻耕后均应镇压耙磨。更多还原

【Abstract】 The comparison experiments in the key over-summer region of wheat stripe rust indicated that post-harvest vil-lage could reduce the density and shorten growth duration of volunteer seedlings,decrease occurring degree of wheat stripe rust,and reduce the amounts of over-summering pathogen and the incidence of wheat strip rust on autumn wheat seedlings.Compared with village with livestock,village with machine had significant effects on controlling wheat stripe rust.Tillage after harvest 30d had more significant effects than conventional tillage after harvest 10d.Squashing,harrow-ing and milling after tillage sometimes could reduce occurrence degree of wheat stripe rust.According to the characteris-tics of Linxia,tillage should be conducted in post-harvest 10d or before sowing seed of winter wheat.Tillage with machine should be extended in the Pingchuan wheat region.Taking into account of harrowing and milling have the role of soil moisture conservation,squashing,harrowing and milling should be made after tillage.更多还原
