不同种植方式对寒地玉米产量和效益的影响

Different Cultivation Mode on Yield and Benifit of Maize in Cold Region

以大田直播为对照,以先玉335和德美亚1号为试材,采用覆膜、育苗移栽和覆膜育苗移栽模式下的130.0、97.5、65.0 cm不同垄距对寒地玉米产量和效益的影响进行了对比研究,以期筛选出效益高的种植模式。结果表明:相同垄距不同模式产量对比,育苗移栽处理>覆膜育苗移栽处理>覆膜处理>直播对照;相同模式不同垄距产量对比,垄距97.5 cm处理>垄距130.0处理;垄距130.0 cm育苗移栽种植方式效益最高,比常规直播种植增收60%以上,适合推广应用。

Taking maize varieties of Xianyu 335 and Demeiya No.1 as experimental materials to study the effect of three different ridge distance of three different cultivation modes on yield and the efficiency of maize.The rage distance was 130.0,97.5,67.0 cm,respectively.The results showed that the yield comparison of different cultivation modes with the same ridge distance,the raise seedling and transplanting mode〉film and raise seedling and transplanting mode〉film mode〉directly sowing mode.The yield comparison of different ridge distance with the same cultivation mode,the ridge distance of 97.5 cm treatment〉the ridge distance of 130.0 cm treatment.The raise seedling and transplanting mode with the ridge distance of 130.0 cm could obtain the highest benefit,which could increase the income by 60% compared to the common directly sowing,suitable for application.
