摘要: 本文以紫菜头品种‘BR07-5’为试验材料,研究天津地区不同播种期、不同播种覆土厚度、不同栽播方式和不同采收期对紫菜头生长和产量的影响。结果表明,夏末秋初播种的紫菜头单根重和产量随着播种期的延后而显著降低,但播种过早,肉质根的质地较硬,确定适宜的播种期为8月5日。0.5 cm播种覆土处理的出苗时间较1.5 cm处理和2.5 cm处理的显著变短,且0.5 cm播种覆土处理的出苗率显著高于其他2个处理。幼苗移栽处理的紫菜头株高显著小于直播处理,而叶片数和叶片重量大于直播处理,肉质根的纵径、横径、单根重和产量均显著小于直播处理,可以在间苗时,通过幼苗移栽来弥补缺苗,以保证较高的产量。11月7日采收的紫菜头单根重、产量和质地较好。

Abstract: With red beetroot(Beta vulgaris L. var. rapacea Koch.)cultivar ‘BR07-5’ as the experimental material, effect of different sowing dates, different covering soil thickness after sowing, planting and sowing patterns and different harvest dates on growth and yield of red beetroot were studied in Tianjin area. The results showed that individual root weight and yield of red beetroot sowed in late summer and early autumn were significantly decreased as postponing sowing date, but fleshy root texture was firmer when red beetroot was sowed too early, so it was confirmed that the appropriate sowing date was August fifth. Seedling emergence time of treatment of covering soil 0.5 cm after sowing was significantly shorter than those of treatments of 1.5 cm and 2.5 cm and seedling emergence rate of treatment of covering soil 0.5 cm after sowing was significantly higher than those of other two treatments. The plant height of transplanting seedling treatment was significantly lower than that of direct sowing treatment, while leaf number and leaf weight were greater than that of direct sowing treatment, transverse diameter and vertical diameter of fleshy root, individual root weight and yield were all lower than that of direct sowing treatment. While thinning seedling we could remedy missing seedlings and ensure higher yield through transplanting seedling. Individual root weight, yield and texture of red beetroot harvested in November seventh were better.
