不同播期对黄秋葵生长及发育的影响

Effects of Different Sowing Data on the Growth and Development of Hibiscus esculentus L.

研究了6个不同播期对黄秋葵生长发育的影响。结果表明,播期在3月24～31日,对黄秋葵株高、茎粗、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,对黄秋葵茎粗、分枝数和折算产量也有作用,并降低第一果节位,但果实畸形率高;播期在4月7～14日,对黄秋葵株高和果实品质有作用,但折算产量明显较低。

Effects of six different sowing data on the growth and development of H.eseulentus L. were studied. The result showed that sowing data on March 24-31th had remarkable effects on plant height, stem-diameter, leaf area, eoversion yield, fruit shape and quality. It had some effects on stem-diameter, number of branches and eoversion yield, while relatively low node of first fruit and high irregular fruit rate to sow in March 11-18th. It had remarkable effects on plant height and fruit quality, while relatively low plot yield to sow in April 7-14th.
