摘要
以河南主推的玉米品种为材料,在2020—2021年研究不同基因型玉米间作对玉米多种病害抗性和产量的影响,旨在为河南种粮大户提供理论依据。以德单5号、登海605、中科玉505、裕丰303为材料,研究品种间作对群体产量以及茎腐病、小斑病、穗腐病和南方锈病发病的影响。结果表明,不同基因型玉米间作较单作能够提高复合群体对茎腐病、小斑病、穗腐病和南方锈病的抗性,间作产量均远远高于各品种单作产量,增产效益显著。德单5号与登海605间作更能提高复合群体产量,稳产性更有保障。
In 2020-2021,the effects of intercropping of different maize genotypes on multiple disease resistance and yield were studied using the main maize in Henan Province as materials,aiming at providing theoretical basis for farmers in Henan Province.Dedan 5,Denghai 605,Zhongkeyu 505 and Yufeng 303 were used as materials to study the effects of intercropping on population yield,as well as the incidence of stem rot,leaf spot,ear rot and southern rust.Results showed that intercropping different genotypes of maize could improve the resistance of the composite population to stem rot,small leaf spot,ear rot and southern rust compared to monocropping.The yield of intercropping was significantly higher than that of monocropping each variety,with significant yield increase benefits.Intercropping between Dedan 5 and Denghai 605 could improve the yield of the composite population and ensure the stability of yield.
