摘　　要：[目的]获取华南地区黄秋葵高产的最佳刈割高度。[方法]设置刈割高度1008、06、04、53、0 cm几个处理,以摘叶处理为对照,测定不同刈割高度对黄秋葵茎、叶产量及茎叶比的影响。[结果]黄秋葵叶产量以刈割高度30 cm的处理最高,为15 622.20 kg/hm2,最低的是刈割高度100 cm的处理;茎产量以刈割高度45 cm的处理最高,为95 550.60 kg/hm2,最低的是摘叶处理;茎叶比以刈割高度100 cm的处理最高,为1.49,最低的是刈割高度45 cm的处理;总物质产量以刈割高度45 cm的处理最高,为79 155.60 kg/hm2,摘叶处理的最低。如果种植用于取叶片青饲动物则应取30 cm的刈割高度;以黄秋葵的茎叶为材料的饲料加工种植应取45 cm的刈割高度。[结论]为黄秋葵生产实践提供了理论依据。[ Objective] The highest cutting height of high-yielding okra grown southern China was explored. [ Method ] The treatment of cutting height of 100, 80, 60, 45, 30cm and removal leaf（CK） was designed and the effect of the different cutting heights on okra stem, leaf yield and the rate of item and leaf was measured. [Results] The result showed that the yield of leaf was the biggest atthe cutting height of 30 cm（15 622.20 kg/hm^2） and its lowest yield was at the height of 100 cm. The yield of stem was the biggest at the cutting height of 45 cm（95 550.60 kg/hm^2） and its lowest yield was from the CK. The ratio of stem and leaf was best at the cutting height of 100cm（1.49） and its lowest yield was at the height of 45cm. The highest total biomass was at the height of 45 cm（79 155.60 kg/hm^2） and its lowest yield was from the CK. The highest yield of the leaf as feed was at the cutting height of 30 cm and the highest yield of the stem and leaf as feed was at the cutting height of 45 cm. [ Conclusion ] The theoretical basis of okra production was provided.
