摘　　要：以海藻酸钠、有机硅、核黄素、80%大豆低聚糖和水杨酸为试材,采用土培试验,对比研究了几种植物生理活性物质在其最佳施用浓度时对蕹菜生长及品质的影响。结果表明:喷施有机硅对蕹菜促生长效果最好,鲜重和干重分别比对照增加38.5%和74.5%;此外,还能显著提高叶片中维生素C含量。其次是水杨酸处理,鲜重比对照增加37.7%,维生素C含量和可溶性蛋白质含量也均显著提高。海藻酸钠和80%大豆低聚糖的促生长效果相对较差。Sodium alginate,silicone,riboflavin,80%soybean oligosaccharides and salicylic acid were used as test materials,soil culture was used to comparatively study effects of several physiologically active substances from plants at their best application concentration on the growth and quality of water spinach（Ipomoea aquatica Forsk.）.The results showed that spraying silicone had the best growth-promoting effects on water spinach under this experiment condition,which respectively increased fresh weight and dry weight by 38.5%and 74.5%,compared with the control;moreover,vitamin C content in leaves was significantly improved.Next came the treatment of salicylic acid.Its fresh weight was increased by37.7%,and the contents of vitamin C and soluble protein were also significantly improved.The growth-promoting effects of sodium alginate and 80%soybean oligosaccharides were comparatively worse.
