摘　　要：为研究控释肥养分释放特性及烤烟养分吸收与利用的规律,探求提高烟叶质量的新途径,通过控释肥养分释放试验和烤烟盆栽试验,研究了控释肥对烤烟农艺性状的影响。结果表明：烤烟移栽后100d,控释肥处理与CCF处理相比株高增幅为1.5~16.5cm,茎围增幅为0.54~1.22cm,最大叶面积增幅为50.2~199.6cm2,叶片干物质累积量增幅为20.6~29.0g,且控释肥处理叶片和植株干物质累积量与CCF处理差异皆达到5%显著性水平,因此施用控释肥能够促进烤烟生长,显著促进干物质累积,其中尤以SRPF、CRPF和CRCF控释肥处理效果显著。In order to study the nutrient release characteristics of controlled release fertilizer and the regularity of nutrient absorption and utilization of flue-cured tobacco,explore new ways to improve the quality of tobacco leaves,through the nutrient release experiment of controlled release fertilizer,the effect of controlled release fertilizer on agronomic characters in flue-cured tobacco was investigated in pot experiments.The results showed that after transplanting flue-cured tobacco for 100 d,plant height of controlled release fertilizer treatments had an increase of 1.5~16.5cm,stem girth had an increase of 0.54~1.22 cm,maximum leaf area had an increase of 50.2~199.6cm2,dry matter accumulation in leaf had an increase of 20.6~29.0g compared with the CCF treatment.Among fertilization treatments,the dry matter accumulation reached significant difference at 0.05 level between controlled release fertilizer treatments and CCF treatment.SRPF,CRPF and CRCF treatments could significantly increase dry matter accumulation of tobacco.
