摘　　要：利用珍珠岩、草炭、蛭石为育苗基质,施用农业跨越计划包膜控释肥中试项目制作的控释肥(20-8-10),进行包膜肥在波斯菊穴盘育苗上的效果试验,分析不同施肥量对波斯菊苗期生长的影响,探讨控释肥在穴盘育苗上应用的可行性及最佳施用量。研究结果表明,控释肥处理的育苗基质养分释放与波斯菊幼苗对养分的吸收基本吻合,达到了“供-需”的动态平衡;每个穴盘施入控释肥量为117g(克)时,由于施肥量过大对波斯菊幼苗的生长产生抑制作用,施入控释肥量为35g(克)时,育苗效果最好。The effects of controlled-release fertilizer applied in plug-seedling with medium of calliopsis （Coreopsis tinctorta ）were studied. The controller- release fertilizer（20 -8- 10）made by Manufacturing Technologies of Controlled- Release Fertilizers of the National Ministry of Agriculture program were used to study the feasibility of controlled - release fertilizers on Plug - seedling and the optimum amount of fertilizer. Compared with the effects of CRF on calliopsis at different application rates. The results showed that nutrient released from controlled -release fertilizgr and the nutrient absorption of seedlings were similar and reached“supply-demand” dynamic balance. When controlled- release fertilizer application amount was 117 g, the growth of seedlings was restrained. The optimum amount of fertilizer on calliopsis plug - seedling was 35 g.
