摘要
为研究不同施肥方式对黄秋葵生长及产量的影响,以石秋葵1号和红玉为试验材料,以基肥为对照,选用叶面肥(磷酸二氢钾)和N、P、K质量比例为20∶20∶20的大量元素水溶肥料进行肥效对比试验。调查结果发现:施肥对石秋葵1号和红玉的生长势、抗病性和产量具有较大的影响;与对照相比,叶面喷施0.2%的磷酸二氢钾,667 m^2施5 kg大量元素水溶肥料,更利于黄秋葵的生长,而磷酸二氢钾较大量元素水溶肥料更利于提高黄秋葵产量。
In order to study the influence of different fertilization methods on the growth and yield of okra, comparison test was car ried out with foliar fertilizer KH2PO4 and water-soluble fertilizer whose proportion of the N, P, K was 20:20:20. The base fertilizer was used as control(CK) and ’Shiqiukui No.1’ and’Hongyu’ were taken as the experimental materials. According to the survey results, fertilization had a great impact on the growth vigor, disease resistance and yield of ’Shiqiukui No.1’ and ’Hongyu’. Compared with CK, spraying 0.2% KH2PO4 and water soluble fertilizer 5 kg per 667 m^2 were more suitable for the growth of okra. Furthermore, the foliar application of KH2PO4 was more effective than the application of water-soluble fertilizer to increase the yield of okra.
