摘　　要：研究了6个不同播期对红秋葵生长及发育的影响,结果表明：播期在3月24～31日,对红秋葵株高、茎粗、开展度、叶面积、折算产量、果形和品质均有明显的促进作用;播期在3月11～18日,对红秋葵茎粗、分枝数和折算产量也有作用,明显降低第一果节位,但畸形果比例增加;播期在4月7～14日,对红秋葵株高和果实品质有作用,但折算产量明显较低.折算产量与开展度、叶面积和可溶性糖之间存在明显的相关.Effects of six different sowing dates on the growth and development of H. coccineus （Medicus） Walt were studied. The result showed that sowing dates from March 24 th to 31 st had remarkable promoting effects on plant height, stem-diameter, leaf area, conversion yield, fruit shape and quality of the plant; sowing dates from March 11 th to 18 th also promoted stem-diameter, number of branches and conversion yield, and the first fruiting node was lowered, but a high rate of irregular fruit was recorded; in the treatment of sowing on April 7-14 th, plant height and fruit quality were improved, but the conversion yield was relatively low. Coversion yield was found to be in significant correlation with expansion degree, leaf area and soluble sugar content.
