以乌塌菜为试材,采用正交实验设计,研究了品种、海拔高度、播期、栽培密度4个主要栽培因子对乌塌菜产量的影响,以提高乌塌菜在高海拔地区的增产潜力。结果表明:最佳品种为“淮南黑心乌”;最佳海拔为1 500m;最佳播期为4月15日;最佳栽培密度为15cm×15cm。
The experiment was carried out by using Oryza sativa L. using orthogonal design. The effects of four major cultural factors including cultivars, altitude, sowing date and planting density on the yield of Brassica oleracea were studied in order to increase the yield of Brassica campestris in high altitude potential. The results showed that the best varieties were “Huainan black heart Ukraine”; the best altitude was 1 500 m; the best sowing date was April 15; and the best planting density was 15 cm × 15 cm.
