摘　　要：研究不同花卉专用控释肥对白掌生长的影响,为白掌栽培生产筛选合适的花卉专用控释肥,为我国花卉生产提供科学依据。以白掌品种“美酒”为供试作物,5种不同花卉专用控释肥为供试肥料,通过盆栽试验,研究不同花卉专用控释肥对白掌生长和整体品质的影响,施用控释肥((15-10-12+2MgO+TE)控释期210~240 d)白掌株高、冠幅、EC值、分枝数、整体品质、鲜重等多方面表现突出。在出货期间,花卉专用控释肥((15-10-12+2MgO+TE)控释期210~240 d)比施用等养分水溶肥料处理(CK)分别提高7.78%、29.91%、185.0%、21.2%、27.0%;花卉专用控释肥((15-10-12+2MgO+TE)控释期210~240 d)的养分释放速率能够与白掌需肥规律同步,能够促进白掌对营养物质的吸收,从而提高肥料利用率。花卉专用控释肥((15-10-12+2MgO+TE)控释期210~240 d)可作为白掌的推荐用肥。The effects of different flower specific controlled-release fertilizers on the growth of Spathiphyllum were studied in order to screen suitable flower specific controlled-release fertilizers for cultivation and production of Spathiphyllum and provide scientific basis for flower production in China.Five kinds of flower specific controlled-release fertilizers were used to study the effects of different flower specific controlled-release fertilizers on the growth and overall quality of Spathiphyllum by pot experiment.The application of controlled-release fertilizer((15-10-12+2MgO+TE)with 210-240 d controlled release period)showed outstanding effects on the height,crown width,EC value,branch numbers,overall quality and fresh weight of Spathiphyllump;compared with the application of water-soluble fertilizer(CK)treatment,the flower specific controlled-release fertilizer treatment increased by 7.78%,29.91%,185.0%,21.2%and 27.0%,respectively.The nutrient release rate of flower specific controlled-release fertilizer((15-10-12+2MgO+TE)with 210-240 d controlled release period)could keep pace with the law of fertilizer demand of white palm,and promote the absorption of nutrients by Spathiphyllum,so as to improve the fertilizer utilization rate.Flower specific controlled-release fertilizer((15-10-12+2MgO+TE)with 210-240 d controlled release period)could be used as the recommended fertilizer for Spathiphyllum.
