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。
The results of comparative experiments in the summer of wheat stripe rust showed that the tillage of wheat after harvesting could reduce the density of self-grown seedling, delay the growth period and reduce the occurrence of stripe rust, so as to reduce the incidence of stripe rust over summer and reduce the incidence of autumn seedling effect. In contrast, mechanical tillage was more obvious than tillage tillage, and the effect of turning tillage 30 days after wheat harvesting was more pronounced than that of conventional wheat tillage after 10 days of tillage. The effects of tilling and milling after tilling were sometimes reduced . According to the characteristics of Linxia area, about 30 days after harvesting of wheat, winter wheat should be plowed before sowing, and plowing promotion should be intensified in Pingchuan wheat area. Taking into account the role of harrowing also moisturizing, plowing and grinding should be suppressed after tilling.
