摘　　要：【目的】明确不同覆膜方式对马铃薯田间杂草的防效以及对马铃薯生理指标、产量和商品薯率的影响。【方法】以马铃薯田主要杂草为研究对象,采用随机区组设计,研究白膜、白膜+330 g/L二甲戊灵、黑膜、黑膜+330 g/L二甲戊灵4种覆膜方式对马铃薯田间杂草的防效及对马铃薯的安全性。【结果】黑膜+330 g/L二甲戊灵处理对主要杂草的防效最好;达到95%以上,马铃薯的出苗率达到95.72%;折合产量达到2334.42 kg/667 m^(2),较对照增产24.30%;商品薯率达80.07%。【结论】黑膜+330 g/L二甲戊灵处理对田间主要杂草防除效果最好,建议推广应用。[Objective]This study aimed to determine the effectiveness of different mulching methods for weed control in potato fields and their effects on potato physiological indicators,yield,and marketable potato rate.[Method]The main weeds in potato fields were studied using a randomized block design.Four mulching treatments,including white mulch,white mulch with 330 g/L dimethomorph,black mulch,and black mulch with 330 g/L dimethomorph,were investigated for their weed control effectiveness and safety on potatoes.[Result]The black mulch with 330 g/L dimethomorph treatment showed the best weed control effectiveness,with a control rate of over 95%and a potato emergence rate of 95.72%.The equivalent yield reached 2334.42 kg/667 m2,representing a 24.30%increase compared to the control.The marketable potato rate reached 80.07%.[Conclusion]The black mulch with 330 g/L dimethomorph treatment exhibited the best weed control effectiveness in the field,and its application is recommended for promotion.
