不同种植模式对春播黄秋葵嫩荚和种子产量的影响

Effects of Different Planting Patterns on Fresh Pod and Seed Yields of Spring Planted Hibiscus esculentus L.

为了探究不同种植模式对春播黄秋葵嫩荚和种子产量的影响,以新东京5号为试验材料,采用高密度等行距、中密度大小行两种种植模式,分期采收黄秋葵嫩荚和种子并计产。结果表明:结荚期内,伴随生育进程,两种种植模式下的嫩荚产量变化趋势一致,产量主要集中在前期;尽管中密度大小行种植管理比较方便,但高密度等行距处理的嫩荚和种子较中密度大小行种植模式分别增产16.8%和13.3%。实行合理密植是黄秋葵高产的重要措施。

In order to study the effects of different planting patterns on fresh pod and seed yields of Hibiscus esculentus L.,the New Tokyo No. 5 was directly planted under two planting patterns（ equal row spacing with high density,wide- narrow row spacing with middle density）,and the fresh pod and seed were harvested and measured by stages. The results showed that during the pod- setting stage,the change trend of fresh pod yield under two planting patterns was consistent with the growth process moving forward,and the yield was mainly focused on the earlier stage. Compared to wide- narrow row spacing with middle density,the fresh pod and seed yields under equal row spacing with high density increased by 16. 8% and 13. 3% respectively.Thus,rational close planting was an important measure to increase yield of okra.
