摘要
为研究宽窄行种植模式在陕西省宝鸡市对玉米产量构成及产量的影响,通过设置两种宽窄行种植比例T1(80 cm∶40 cm)、T2(70 cm∶50 cm)与等行距种植模式(60 cm)对玉米品种宝玉803成熟期产量构成及产量的影响,结果表明,在T2处理下,宝玉803穗行数、行粒数、穗长、百粒重有增加趋势,产量显著增加5.00%。因此宝玉803在宝鸡地区采用“70 cm∶50 cm”的宽窄行比例有利于产量的提高。
To evaluate the effects of wide–narrow row planting on yield components and grain yield of maize‘Baoyu 803’in Baoji,Shaanxi Province,two wide–narrow row configurations—T1(80 cm:40 cm)and T2(70 cm:50 cm)—and an equal-row spacing pattern(row spacing of 60 cm)were compared at maturity.The results showed that,relative to equal-row spacing,T2 showed increasing trends in the number of kernel rows per ear,kernels per row,ear length,and 100-kernel weight,while grain yield increased significantly by 5.00%.Therefore,the wide–narrow row configuration of 70 cm:50 cm is recommended for maize‘Baoyu 803’in the Baoji region to increase grain yield.
