栽培密度对中秆和矮秆黄秋葵生长发育及产量的影响

摘要

[Objective] The aim was to compare effects of differen! planling densities on growth and developmenl and yiehl of medium height and short height Hibiscus esulelltt+s L.. [Method] The effects of six planting densities on growth and development and yiehl of two ftibiscus esulenttis L. cuhivars( medium height and short height Hibiscus esulentus L.) were studied. [Result] The results showed that there was no significant effect on the growth progress and friut characters of Hibiscus estllentus L.., hut significant effect on the plant height and the total yieht of two Hibiscus estslenttls 1,. euhivars, the plant was heigher with the planting density increased. It was concluded that the feasible planting density of medium height Hibiscus esulentus L. was 37 500 plants/bm2, and the feasible planting density of short height Hibiscus esulentus L. was 49 500 plants/hm2. [Conclusion] The appropriate planting den- sities of medium height and short height Hibiscus esulenttls L.. were 37 500, 49 500 plants/hm2, respectively.%【目的】比较不同密度对中秆和矮秆黄秋葵生长发育及产量的影响。【方法】对中秆和矮秆黄秋葵进行了6个栽培密度研究，分析密度对其生长发育及产量的影响。【结果】不同密度处理对中秆、矮秆黄秋葵的生育进程和花后4d嫩荚性状影响不大；对株高的影响较大，随着密度的加大，株高增高；对嫩荚产量的影响最大，中秆—黄啾葵在密度为37500株m2时产量最高，矮秆黄秋葵在密度为49500株／hm2时产量最高。【结论】确定了中秆黄秋葵与矮秆黄秋葵的适宜栽培密度分别为37500、49500株／hm2。
