种植密度对黄秋葵生长势、抗病性和产量的影响
|
摘要
为研究不同种植密度对黄秋葵生长势、抗病性和产量的影响,对‘石秋葵1号’‘红玉’和‘五福’这3个品种进行了5个种植密度的研究,调查分析了密度对其生长势、抗病性和产量的影响。结果表明,种植密度对‘石秋葵1号’‘红玉’和‘五福’的茎粗、株高、单株结果数、单果质量等影响差异显著。随种植密度的增大,茎粗、单株结果数和单果质量基本呈逐渐下降的趋势,株高逐渐增高,667 m~2产量先缓慢升高后快速降低,在株距45、50 cm(中密度)时产量最高。种植密度在株行距45 cm×70 cm和50 cm×70 cm时,黄秋葵的品质和产量最优。
To study the effects of planting densities on the growth vigour, disease resistance and yield of okra, three okra varieties('Shiqiukui No.1', 'Hongyu' and 'Wufu') were used in this study, five planting densities were carried out, and the growth vigour, disease resistance and yield of of three okra varieties were investigated. The results showed that the stem diameter, plant height, the fruit number of per plant, single fruit weight, single plant yield and yield per 667 m~2 of 'Shiqiukui No.1', 'Hongyu' and 'Wufu' were significantly affected by the planting density. With the increase of planting density,the stem diameter, the fruit number of per plant and the weight of single fruit gradually decreased, while the plant height increased gradually with the planting density, however, the yield on per 667 m~2 increased slowly and then decreased rapidly with the increase of planting density. The plants showed the highest yield when the plant spacing was 45 cm and 50 cm.In conclusion, when the planting density was 45 cm×70 cm and 50 cm×70 cm, the quality and yield of okra were optimal.
